As a conventional example of a lighting fixture using a semiconductor light emitting element (LED), there is one disclosed in Patent Document 1, for example.
This luminaire includes a plurality of LED connectors (semiconductor light-emitting element holders) and a plurality of LED modules integrated with the respective LED connectors (LED elements mounted on a substrate). Each LED connector includes one positive electrode contact and one negative electrode contact, and the positive electrode contact and the negative electrode contact provided on each LED connector are connected to the anode and the negative electrode of the LED element, respectively. The outer peripheral surface of the rectangular housing that forms the outer shape of each LED connector is composed of four flat side surfaces, and the two side surfaces that are spaced apart from each other with the central portion of the housing interposed between the positive electrode contact and the negative electrode One positive electrode contact receiving hole and one negative electrode contact receiving hole for receiving a part of each contact are formed.

However, the above lighting fixture has the following drawbacks.
That is, when connecting each unitary object, the positive electrode wire and the negative electrode cable are respectively formed in the positive electrode contact housing hole and the negative electrode contact housing hole formed on the two surfaces of the respective integrated body (the LED connector) which are separated from each other. Must be connected (inserted).
Therefore, it is not easy to connect (insert) and disconnect (draw) the positive electrode wire and the negative electrode wire with respect to each integrated object, and the assembling workability of the lighting fixture is poor.

  Further, when connecting the integrated objects in a straight line, the positive electrode contact accommodating holes and the negative electrode contact accommodating holes of the adjacent integral objects (LED connectors) are opposed to each other, and the opposed positive electrode contact accommodating holes are positive electrodes. The negative electrode contact receiving holes connected by the electric wire and opposed to each other are connected by the negative electrode electric wire. That is, the operator puts a positive electrode wire and a negative electrode wire into the opposing positive electrode contact accommodation hole and negative electrode contact accommodation hole in a state where a hand (finger) is placed between the opposing surfaces of adjacent ones (LED connectors). Will be inserted. Therefore, since it is necessary to ensure a space for the operator's hand (finger) to be inserted between adjacent ones (LED connectors), it is not possible to dispose each one (LED connector) at a narrow interval.

  An object of the present invention is to easily attach and detach a cable to and from the anode-side cable insertion hole and the cathode-side cable insertion hole of a semiconductor light-emitting element holder, and when connecting a plurality of semiconductor light-emitting element holders in a chain. An object of the present invention is to provide a semiconductor light emitting element holder, a semiconductor light emitting element module, and a lighting fixture capable of narrowing the interval between adjacent semiconductor light emitting element holders.

  The holder for a semiconductor light emitting element of the present invention is formed in a case main body having an accommodation space in which a semiconductor light emitting element unit, which is an integrated body of the semiconductor light emitting element mounted on the substrate and the substrate, can be placed, and the case main body. Each of the semiconductor light emitting elements disposed in the housing space is exposed to the outside of the case body, and formed on only one cable connection surface that forms a part of the outer peripheral surface of the case body and is a plane. Anode-side cable insertion hole and cathode-side cable insertion hole through which a cable can be inserted and removed, and electrically conductive with the anode of the semiconductor light-emitting element supported by the insulating portion of the case body while being positioned in the housing space And an anode contact connected to the cable inserted into the anode-side cable insertion hole and a cathode of the semiconductor light-emitting element and electrically conductive A cathode contact connected to the cable inserted in the pole-side cable insertion hole, and an anode-side support portion and a cathode-side support portion provided inside the case body, wherein the anode contact and the cathode contact are the anode When the cable is inserted into the side cable insertion hole and the cathode side cable insertion hole, the anode side support portion and the cathode are elastically deformed in directions away from the anode side support portion and the cathode side support portion, respectively. It has the elastic deformation part which clamps the said cable between each of the side support parts, It is characterized by the above-mentioned.

  The cable connected to the cathode contact facing the cathode side cable insertion hole of the semiconductor light emitting element holder is connected to the anode side cable insertion hole of the semiconductor light emitting element holder different from the semiconductor light emitting element holder. It may be connectable to the opposing anode contact.

  The module for semiconductor light emitting elements of the present invention is characterized by comprising the semiconductor light emitting element unit disposed in the housing space.

The substrate of the semiconductor light emitting element unit includes an anode and a cathode that are electrically connected to the semiconductor light emitting element, and an indicator that indicates a position of either the anode or the cathode, and the case main body includes the semiconductor light emitting element unit. You may form the hole for parameter | index visual recognition which exposes the said parameter | index outside when it attaches in a regular position with respect to a main body.
Further, the indicator viewing hole may be provided in the vicinity of the anode side cable insertion hole and the cathode side cable insertion hole.

  The lighting apparatus of the present invention is a light projecting member that is capable of transmitting illumination light emitted from the semiconductor light emitting element and that surrounds the semiconductor light emitting element holder, and a heat radiating member that contacts the substrate exposed to the outside through the substrate exposing opening. And a protective cover member.

The holder for a semiconductor light emitting device (semiconductor light emitting device module and lighting fixture) of the present invention has a part of the outer peripheral surface of the case body and a positive cable insertion hole and a negative cable insertion only on one flat cable connection surface. It has a hole. Therefore, when attaching and detaching each cable to and from the semiconductor light emitting element holder, it is only necessary to attach and detach each cable from the one side of the case body to the anode side cable insertion hole and the cathode side cable insertion hole. Each cable can be easily attached to and detached from the light emitting element holder (the anode side cable insertion hole and the cathode side cable insertion hole).
Furthermore, the holder for semiconductor light emitting elements (semiconductor light emitting element module and lighting fixture) of the present invention is such that the cable connection surfaces of the respective semiconductor light emitting element holders face in the same direction (the cable connection surfaces of adjacent semiconductor light emitting element holders). The respective semiconductor light emitting element holders can be connected in a straight line without facing each other. Therefore, the operator does not need to put a hand (finger) between the opposing surfaces of the adjacent semiconductor light emitting element holders when attaching and detaching the cable, so the interval (connection pitch) between the adjacent semiconductor light emitting element holders is shortened. However, it is possible to connect the holders for semiconductor light emitting elements in a chain.

Further, an engaging claw 39 (substrate holding portion) is provided on the rear surface of the lower end portion of the front elastic deformation piece 38 and the front surface of the lower end portion of the rear elastic deformation piece 38, respectively.

The anode-side conductive member 40 (anode-side contact) and the cathode-side conductive member 50 (cathode-side contact) are made of copper alloy (eg phosphor bronze, beryllium copper, titanium copper) or corson copper alloy having spring elasticity in order. It is molded into a shape shown in the figure using a remittance die (stamping), and after a base is formed by nickel plating on the surface, gold plating or tin copper plating is applied.
The anode side conductive member 40 includes a flat base plate portion 44 including a right side portion 41, a front portion 42, and a left side portion 43. A pair of left and right escape recesses 42a is formed at the rear edge of the front portion 42, and a circular hole 45 is formed as a through hole in the right side portion 41. A cable anode contact 47A extends rearward from the rear end portion of the upper surface of the right side portion 41. An elastically deformable portion 48 formed by folding back toward the front is provided at the rear end portion of the cable anode contact 47A. A connecting portion 54 extends upward from the rear end portion of the upper surface of the left side portion 43. A central portion in the longitudinal direction of the LED anode contact 55 (substrate holding portion) extending in the front-rear direction is connected to the upper end portion of the connection portion 54, and contact end portions 56 are provided at the front and rear end portions of the LED anode contact 55.

Each is located in the storage recess 32. Although the elastic deformation of the front portions of the cable anode contact 47A and the cable cathode contact 47B is restricted by the corresponding contact insertion grooves 37, the left and right elastic deformation portions 48 have the anode-side cable insertion groove 30A and the cathode-side cable insertion groove. In the interior of 30B, the base end portion (rear end portion) can be elastically deformed in the left-right direction (further, the rear portions of the cable anode contact 47A and the cable cathode contact 47B can be elastically deformed).

And can be elastically deformed in the vertical direction.

The cover member 60 having a substantially rectangular shape in plan view is formed by injection molding an insulating synthetic resin material. The cover member 60 includes a flat substrate portion 61, and a substrate exposure opening 62 having a rectangular shape in plan view is formed as a through hole in the central portion of the substrate portion 61. Recessed recesses 63 are formed at two positions on the left and right sides of the front and rear edges of the substrate exposure opening 62. Further, at the four positions on the lower surface of the cover member 60, two presser protrusions 64 positioned immediately before the two front clearance recesses 63 and two pressers positioned immediately after the two rear clearance recesses 63. The projection 64 is protruded downward. Engagement convex portions 65 project upward at both front and rear side edges of the upper surface of the substrate portion 61, and engagement holes 66 are formed as through holes in the front and rear engagement convex portions 65. A pair of left and right contact support protrusions 67 project upward in the vicinity of the rear end of the right edge of the upper surface of the substrate 61. Circular through holes 68 are formed in the vicinity of two corners located on the diagonal line of the substrate part 61, and annular protrusions 69 are provided at positions corresponding to the through holes 68 on the upper surface of the substrate part 61, respectively. It protrudes upward.
The cover member 60 is attached to the lower surface of the insulator 20 that supports the anode side conductive member 40 and the cathode side conductive member 50 from below. Specifically, the front and rear engaging convex portions 65 are positioned in the front and rear engaging concave portions 25 while the lower surface of the insulator 20 is closed by the substrate portion 61, and the front and rear engaging projections 26 are associated with the corresponding engaging convex portions 65.

Further, the two elastic deformation pieces 38 (engagement claws 39) on the front side of the insulator 20 pass through the corresponding two escape recesses 42a and the two escape recesses 63 and protrude below the cover member 60. The elastic deformation piece 38 (engagement claw 39) passes through the corresponding two recesses 63 and protrudes below the cover member 60.
In this manner, the insulator 20 supporting the anode side conductive member 40 and the cathode side conductive member 50 and the cover member 60 are integrated to complete the LED holder 15 (see FIG. 8). Also, the anode side cable insertion groove 30A, the cathode side cable insertion groove 30B, the LED storage recess 31, the contact storage recess 32, the right recess 34, the front recess 35, the left recess 36, and the contact insertion groove 37 of the insulator 20, and a cover A space surrounded by the member 60 is a housing space.

The LED unit 70 includes a substrate 71 having the same shape as the substrate exposure opening 62 and one high-luminance type LED 74 (semiconductor light emitting element, anode of the LED 74) that is electrically connected to an electric circuit (not shown) formed on the upper surface of the substrate 71. Is connected to the anode side circuit of the electric circuit, and the cathode of the LED 74 is connected to the cathode side circuit of the electric circuit). On the upper surface of the substrate 71, the anode side circuit and the cathode of the electric circuit are provided. An anode 72 and a cathode 73 respectively formed on the side circuit are formed. Note that a diffusion lens 75 (see FIGS. 1, 2, and 11) that covers the LED 74 may be fixed to the upper surface of the substrate 71 as necessary. Further, the LED unit is configured as a package type by covering the upper surface of the substrate 71 and the LED 74 with a sealant (not shown) made of a thermosetting resin material or an ultraviolet curable resin material having translucency and insulation. May be.
The LED unit 70 is integrated with the LED holder 15 by fitting into the substrate exposure opening 62 from below. When the substrate 71 of the LED unit 70 is fitted into the substrate exposure opening 62, the anode 72 contacts the rear contact end portion 56 while elastically deforming the LED anode contact 55 upward, and the cathode 73 is the LED cathode contact. Since the rear contact end 52 is contacted while elastically deforming 51 upward, the upward movement of the substrate 71 relative to the LED holder 15 is restricted. Further, the front and rear edges of the substrate 71 press the engaging claws 39 to elastically deform the elastic deformation pieces 38 outward (the front elastic deformation piece 38 is the front and the rear elastic deformation piece 38 is the rear). When the board 71 moves above the respective engaging claws 39 (when the board moves over the engaging claws 39), each elastic deformable piece 38 returns to the free state, and the four engaging claws 39 move from the lower side of the board 71. Engages in four places on the lower surface. Therefore, the LED unit 70 is held by the LED cathode contact 51, the LED anode contact 55, and the four engagement claws 39 so that the lower surface of the substrate 71 is flush with the lower surface of the substrate portion 61 (see FIG. 10). ). Even if the LED unit 70 elastically deforms each elastic deformation piece 38 outward, each elastic deformation piece 38 can only be deformed until it abuts the corresponding presser protrusion 64. Therefore, each elastic deformation piece 38 has an elastic limit. It will not be elastically deformed beyond. Further, when the diffusing lens 75 is provided, when the LED unit 70 is integrated with the LED holder 15, the diffusing lens 75 is loosely fitted in the illumination opening 21 (the diffusing lens 75 is positioned in the LED housing recess 31. The diffusing lens 75 is exposed above the insulator 20 through the illumination opening 21).
Thus, the LED module 10 is completed by integrating the LED unit 70 with the LED holder 15 (see FIG. 9).

  One end of two cables 77 can be connected to the LED module 10. The cable 77 having flexibility includes an electric wire 78 in which a large number of metal wires are bundled, and a covering tube 79 made of an insulating material that covers the surface of the electric wire 78. At both ends of each cable 77, the electric wire 78 is exposed by removing the covering tube 79. When one end of each of the two cables 77 is linearly inserted into the anode-side cable insertion groove 30A and the cathode-side cable insertion groove 30B, the exposed end of the electric wire 78 has a corresponding elastic deformation portion 48 ( While being elastically deformed (in a direction approaching the main body side of the cable anode contact 47A and the cable cathode contact 47B), the elastic deformable portion 48 contacts the elastic deformable portion 48 corresponding to the end of each electric wire 78. It is clamped between inner walls (anode-side support part, cathode-side support part) (see FIG. 11). Therefore, each cable 77 can be easily connected to the cable anode contact 47A and the cable cathode contact 47B by one linear pushing operation to the anode side cable insertion groove 30A and the cathode side cable insertion groove 30B. If each cable 77 is connected to the cable anode contact 47A and the cable cathode contact 47B, the cable 77 cannot be pulled out smoothly even if a pulling force is applied to the cable 77. Therefore, when the cable 77 is pulled out from the anode-side cable insertion groove 30A and the cathode-side cable insertion groove 30B, the tip of the pin (not shown) is inserted into the anode-side cable insertion groove 30A and the cathode-side cable insertion groove 30B through the pin insertion hole 27. The elastic deformation portion 48 is inserted into the inside and further elastically deformed (in a direction approaching the main body side of the cable anode contact 47A and the cable cathode contact 47B) by the tip of the pin. The contact pressure with is reduced. In this way, each cable 77 can be smoothly pulled out with a small pulling force.

The LED module 10 and the cable 77 having the above configuration can be used as components of the lighting fixture 80 shown in FIG.
When configuring the lighting fixture 80 as shown in FIG. 13, four LED modules 10 whose top and bottom directions are reversed (a plurality other than four are acceptable) are arranged in a straight line direction (a direction perpendicular to the paper surface in FIG. 12). Line up. That is, as shown in FIG. 13, both ends of the cable 77 are connected to the anode-side cable insertion groove 30A and the cathode-side cable insertion groove 30B of two adjacent LED modules 10, and one end of these cables 77 is connected to the anode side. In the cable insertion groove 30A, the cable anode contact 47A (elastic deformation portion 48) is connected, and the other end of the cable 77 is connected to the cable cathode contact 47B (elastic deformation portion 48). That is, four LED modules 10 are connected in series.
The luminaire 80 includes a synthetic resin base member 81 having a circular shape in plan view. The lower surface of the base member 81 (the lower surface in FIG. 12, in the case where the direction of the arrow line shown in FIG. A recess is formed on the upper surface, and a chassis 82 (heat radiating member) made of a metal plate is fixed to the bottom surface (upper surface in FIG. 12) of the recess. The LED modules 10 connected in a straight line as described above are engaged with the positioning recesses provided in the chassis 82 with the presser protrusions 64, and the corner recesses 23 side with respect to the two through holes 24. The fixing bolt 83 is inserted into the base member 81 and the male screw portion of each fixing bolt 83 that has passed through the through-hole 24 is screwed into two female screw holes (not shown) formed in the chassis 82, respectively. 82). When the LED module 10 is fixed to the base member 81, the lower surface (upper surface in FIG. 12) of the substrate 71 exposed through the substrate exposure opening 62 contacts the chassis 82. Further, on the lower surface of the base member 81 (the lower surface in FIG. 12 and the upper surface when the arrow direction shown in the drawing is used as a reference), a hemispherical light projecting covering the lower surface of the base member 81 and the LED module 10 The cover 84 is covered.
The lighting fixture 80 including the plurality of LED modules 10, the plurality of cables 77, the base member 81, the chassis 82, the fixing bolt 83, and the light projecting cover member 84, for example, projects light from the base member 81 as shown in FIG. It can be fixed to the ceiling plate 85 with a screw or the like with the side opposite to the protective cover member 84 facing upward. An end portion of the cable 77 of the LED module 10 located at one end in the connection direction (linear direction) of the LED module 10 is on the opposite side of the LED module 10 from above the ceiling plate 85 through a through hole 86 formed in the ceiling plate 85. Pull out and connect to the anode of the power source through a control device (not shown), and the end of the cable 77 of the LED module 10 located at the other end in the connecting direction (straight direction) of the LED module 10 is opposite to the LED module 10. The part is pulled out above the ceiling plate 85 through a through hole (not shown) formed in the ceiling plate 85, and is connected to the cathode of the power source through a control device. When the switch (not shown) is switched from OFF to ON, the current generated by the power source is the cable 77, the anode side conductive member 40 (cable anode contact 47A, LED anode contact 55), and the cathode side conductive member 50 (cable. Each LED 74 emits light through an electrical circuit of the substrate 71 via the cathode contact 47B for LED and the cathode contact for LED 51) (if a diffusion lens 75 is provided, it is diffused by the diffusion lens 75). The illumination light emitted from the LED 74 is directed toward the light projecting cover member 84 while being reflected by the tapered reflecting surface 22 of the insulator 20, passes through the light projecting cover member 84, and is irradiated to the outside. On the other hand, when the switch is switched from ON to OFF, the supply of current to the LEDs 74 is interrupted, so that each LED 74 is turned off.

According to the present embodiment described above, the anode-side cable insertion groove 30A and the cathode-side cable insertion groove 30B are formed only on the rear surface (cable connection surface consisting of a flat surface) of each LED module 10 (LED holder 15). . Therefore, when attaching / detaching each cable 77 to / from the LED module 10, each cable 77 is attached / detached to / from the anode-side cable insertion groove 30 </ b> A and the cathode-side cable insertion groove 30 </ b> B from one surface side (rear side) of the LED module 10. Therefore, each cable 77 can be easily attached to and detached from the LED module 10 (the anode side cable insertion groove 30A and the cathode side cable insertion groove 30B).
Furthermore, each LED module 10 (LED holder 15) has the rear surface of each LED holder 15 (a flat cable connection surface) faced in the same direction (the cable connection surfaces of adjacent LED modules 10 face each other). In other words, the LED modules 10 can be connected in a straight line. For this reason, the operator does not need to put a hand (finger) between the opposing surfaces of the adjacent LED modules 10 when attaching and detaching the cable 77, so that each LED module 10 is shortened while shortening the interval (connection pitch) between the adjacent LED modules 10. It is possible to connect the modules 10 in a straight line.

Further, the LED module 10 is integrated with the cable anode contact 47A, the cable cathode contact 47B, the LED cathode contact 51, the LED anode contact 55, and the LED unit 70 (the cable anode contact 47A, the cable cathode contact). 47B, LED cathode contact 51, LED anode contact 55, and LED unit 70 can be fixed to another member (for example, chassis 82), so that LED module 10 can be easily fixed to another member. it can.
Moreover, the LED module 10 can be fixed to another member (for example, the chassis 82) with a small number of steps. Therefore, maintenance when replacing the old LED unit 70 fixed to another member with a new one is easy.
Further, the LED anode contact 47A, the cable cathode contact 47B, the LED cathode contact 51, the LED anode contact 55, and the LED 74 are covered with the LED holder 15, so that the LED module 10 is fixed to another member. When doing so, there is little risk that the LED 74 (diffuse lens 75) will come into contact with other members and be damaged. Further, when the LED holder 15 is fixed to another member by the fixing bolt 83, the fixing force (load) by the fixing bolt 83 is the cable anode contact 47A, the cable cathode contact 47B, the LED cathode contact 51, and the LED anode contact. 55 and the LED unit 70, the members are not deformed. Therefore, the LED module 10 has a good yield (can suppress the occurrence of defective products) and has a long service life.

Further, the heat generated by the LED 74 is dissipated from the substrate 71 and further transmitted from the substrate 71 to the chassis 82 and is also dissipated from the chassis 82, so that the heat of the LED 74 can be efficiently dissipated to the outside. Therefore, it is possible to prevent a decrease in the light emission efficiency of the LED 74 due to a high temperature.
In addition, since the LED module 10 includes the tapered reflecting surface 22 positioned in the immediate vicinity of the LED 74 (diffuse lens 75), the directivity of the illumination light can be controlled, and uneven brightness of the illumination light can be suppressed.
Further, as shown in FIG. 12, most of the head of the fixing bolt 83 is positioned in the corner recess 23 formed in the insulator 20 (the amount of protrusion of the fixing bolt 83 upward from the upper surface of the insulator 20 is small). Therefore, it is difficult for the illumination light to be blocked by the head of the fixing bolt 83.
Further, the cable anode contact 47A, the cable cathode contact 47B, the LED cathode contact 51, and the LED anode contact 55 are not integrated as a separate body, but are integrated as an anode side conductive member 40 and a cathode side conductive member 50, respectively. Therefore, the LED module 10 (LED holder 15) can be easily assembled as compared with the case where the cable anode contact 47A, the cable cathode contact 47B, the LED cathode contact 51, and the LED anode contact 55 are all separated. It is.

Next, a second embodiment of the present invention will be described with reference to FIGS. Note that members substantially the same as those in the first embodiment are given the same reference numerals with a dash ('), and detailed description thereof is omitted.

The LED module 10 ′ (semiconductor light emitting element module) is obtained by attaching an LED unit 70 ′ (semiconductor light emitting element unit) to an LED holder 15 ′ (semiconductor light emitting element holder).

The LED holder 15 ′ includes an insulator 20 ′ (case body) (insulating part), a cathode side conductive member 90, an anode side conductive member 100, and a cover member 60 ′ (case body) as large components.
The insulator 20 ′ having a substantially rectangular shape in plan view is obtained by injection molding an insulating synthetic resin material, and a substantially rectangular illumination opening 21 ′ is formed at the center thereof. On the top surface of the insulator 20 ', a substantially rectangular tapered reflecting surface 22' is formed as a whole located on the outer peripheral side of the illumination opening 21 '.

An indicator 29A (consisting of the character “+”) is provided in a manner adjacent to the character.

The cathode-side conductive member 90 (cathode-side contact) and the anode-side conductive member 100 (anode-side contact) are made of copper alloy (eg phosphor bronze, beryllium copper, titanium copper) or corson copper alloy with spring elasticity in order. It is molded into a shape shown in the figure using a remittance die (stamping), and after a base is formed by nickel plating on the surface, gold plating or tin copper plating is applied.
The cathode side conductive member 90 includes a flat base plate portion 94 including a right side portion 91, a front portion 92, and a left side portion 93. A pair of left and right escape recesses 92 a are formed at the front edge of the front portion 92. A cable cathode contact 95 extends rearward from the rear end portion of the left side portion 93. The cable cathode contact 95 has an elastically deformable portion 96 that is folded forward. A connection piece 97 extends from the lower surface of the left side of the cable cathode contact 95 toward the right side, and a fixing piece 98 extends forward from the right end of the connection piece 97. Further, an LED cathode contact 99 is provided at the rear end portion of the right side portion 91 and extends obliquely downward to the front after facing the left side.
The anode-side conductive member 100 (contact) separate from the cathode-side conductive member 90 includes a base portion 101, an elastically deformable portion 102 folded back from the rear end of the base portion 101, and a left side from the lower surface of the base portion 101. The cable has an anode contact 105 made up of a connecting piece 103 extending and a fixed piece 104 extending rearward from the left end of the connecting piece 103. Further, from the front end portion of the base portion 101 of the anode-side conductive member 100, there is provided an LED anode contact 106 that extends toward the right and then obliquely downward.
The cathode side conductive member 90 and the anode side conductive member 100 are attached to the bottom surface of the insulator 20 ′ in a state of being separated from each other from below. Specifically, the right side portion 91, the front portion 92, and the left side portion 93 of the base plate portion 94 are fitted into the right side recess portion 34 ', the front side recess portion 35', and the left side recess portion 36 'of the insulator 20', respectively, and the cable cathode. The contact 95 and the cable anode contact 105 are attached to the bottom surface of the insulator 20 'by facing the cathode side cable insertion groove 30B' and the anode side cable insertion groove 30A 'in the front-rear direction. The right side portion 91, the front portion 92, the left side portion 93, and the fixed piece 98 of the cathode side conductive member 90 are immobile with respect to the insulator 20 ′, but the elastic deformation portion 96 is centered on the base end portion (rear end portion). The LED cathode contact 99 can be elastically deformed in the vertical direction. The base 101 and the fixed piece 104 of the anode-side conductive member 100 are immobile with respect to the insulator 20 ′, but the elastic deformation portion 102 can be elastically deformed in the left-right direction around the base end portion (rear end portion). The anode contact 106 can be elastically deformed in the vertical direction.

The cover member 60 ′ having a substantially rectangular shape in plan view is obtained by injection molding an insulating synthetic resin material. The cover member 60 ′ has four upward engaging projections 65 ′, and an engagement recess 65 a is provided on the inner surface of each engagement projection 65 ′. Further, an upward wall is erected on the left end of the rear edge of the cover member 60 ', and an anode-side cable insertion hole 69A and a cathode-side cable insertion hole 69B are formed side by side on this wall. .
The cover member 60 ′ is attached from below to the lower surface of the insulator 20 ′ that supports the cathode side conductive member 90 and the anode side conductive member 100. Specifically, while closing the lower surface of the insulator 20 ′ with the board portion 61 ′, the respective engaging convex portions 65 ′ are respectively positioned in the corresponding engaging concave portions 25 ′, and the respective engaging projections 26 ′ are correspondingly engaged. The protrusion 65 ′ is attached by engaging with the engaging recess 65a. Then, the left and right contact support protrusions 67 ′ are positioned (may be brought into contact with each other) while forming a minute clearance immediately below the cable cathode contact 95 and the cable anode contact 105. Further, the two elastic deformation pieces 38 ′ (engaging claws 39 ′) on the front side of the insulator 20 ′ pass through the corresponding two escape recesses 92a and the two escape recesses 63 ′ and protrude below the cover member 60 ′. The rear two elastically deformable pieces 38 ′ (engaging claws 39 ′) pass through the corresponding two escape recesses 63 ′ and project below the cover member 60 ′.
Thus, the LED holder 15 ′ is completed by integrating the insulator 20 ′ supporting the cathode side conductive member 90 and the anode side conductive member 100 and the cover member 60 ′ (see FIG. 19). Also, the anode side cable insertion groove 30A ′, the cathode side cable insertion groove 30B ′, the LED housing recess 31 ′, the right recess 34 ′, the front recess 35 ′, the left recess 36 ′, and the cover member 60 ′ of the insulator 20 ′, The space surrounded by is the accommodating space.

The LED unit 70 ′ includes a substrate 71 ′ having the same shape as the substrate exposure opening 62 ′, and an LED 74 ′ (semiconductor light emitting element) having substantially the same shape as the illumination opening 21 ′. The anode of the LED 74 ′ is connected to the anode 73A via the anode side circuit of the electric circuit of the substrate 71 ′, and the cathode of the LED 74 ′ is connected to the cathode 72A via the cathode side circuit of the electric circuit. Further, in the vicinity of the anode 73A on the upper surface of the substrate 71 ′, an anode side index 76 (for example, an index composed of characters “+” as shown) indicating the position of the anode 73A is provided.
The LED unit 70 'is integrated with the LED holder 15' by fitting into the substrate exposure opening 62 'from below. When the board 71 ′ of the LED unit 70 ′ is fitted into the board exposure opening 62 ′, the cathode 72A contacts the LED cathode contact 99 while elastically deforming the LED cathode contact 99 of the cathode side conductive member 90 upward, Since the anode 73A contacts the LED anode contact 106 while elastically deforming the LED anode contact 106 of the anode-side conductive member 100 upward, the upward movement of the substrate 71 ′ relative to the LED holder 15 ′ is restricted. Further, the four engaging claws 39 'engage with the four positions on the lower surface of the substrate 71' from below. Furthermore, the anode side cable insertion hole 69A and the cathode side cable insertion hole 69B are located immediately after the anode side cable insertion groove 30A ′ and the cathode side cable insertion groove 30B ′. Further, since the anode side index 76 of the substrate 71 ′ is located directly below the index viewing hole 29 of the insulator 20 ′, the operator can view the index viewing hole 29 and the substrate exposing opening of the cover member 60 ′ from above the insulator 20 ′. The anode side indicator 76 can be visually recognized through 62 ′, and at the same time, the indicator 29A adjacent to the indicator visually recognizing hole 29 can be visually recognized.
Thus, LED module 10 'is completed by integrating LED unit 70' with LED holder 15 '(refer FIG. 14, FIG. 15).

  When one end of the cable 77 ′ is linearly inserted into the anode-side cable insertion hole 69A (and the anode-side cable insertion groove 30A ′) of the LED module 10 ′, the exposed end of the electric wire 78 ′ corresponds. The elastic deformation portion 102 is in contact with the elastic deformation portion 102 while being elastically deformed on the right side (in a direction away from the fixed piece 104), and the end of the electric wire 78 ′ is between the elastic deformation portion 102 and the fixed piece 104 (anode side support portion). (See FIG. 20). Further, when one end of the cable 77 ′ is linearly inserted into the cathode side cable insertion hole 69B (and the cathode side cable insertion groove 30B ′) of the LED module 10 ′, the exposed end of the electric wire 78 ′ corresponds. The elastic deformation portion 96 is brought into contact with the elastic deformation portion 96 while being elastically deformed on the left side (in a direction away from the fixed piece 98), and the end portion of the electric wire 78 ′ is connected to the elastic deformation portion 96 and the fixed piece 98 (cathode side support portion). (See FIG. 20). Therefore, each cable 77 ′ has an anode side cable insertion hole 69 A (and anode side cable insertion groove 30 A ′) and cathode side cable insertion hole 69 B (and cathode side cable) with respect to the cable cathode contact 95 and the cable anode contact 105. It can be easily connected by a single linear pushing operation on the insertion groove 30B ′). When each cable 77 ′ is connected to the cable cathode contact 95 and the cable anode contact 105, the cable 77 ′ cannot be pulled out smoothly even if a pulling force is applied to the cable 77 ′. It is inserted into the anode side cable insertion groove 30A ′ and the cathode side cable insertion groove 30B ′ through the pin insertion hole 27 ′, and the elastic deformation part 96 and the elastic deformation part 102 are elastically deformed by the tips of the pins, thereby elastic deformation. By reducing the contact pressure of the electric wire 78 ′ with respect to the portion 96 and the elastically deformable portion 102, it can be smoothly pulled out with a small pulling force.

The LED module 10 ′ and the cable 77 ′ configured as described above can be used as components of the lighting fixture 80 ′ shown in FIG.
As shown in FIG. 21, when configuring the lighting fixture 80 ′, a large number of LED modules 10 ′ whose top and bottom directions are reversed (only four are shown in FIG. 21 but actually more than four) are linearly aligned. Line up. That is, as shown in FIG. 21, the anode-side cable insertion hole 69A (and anode-side cable insertion groove 30A ′) and cathode-side cable insertion hole 69B (and cathode-side cable insertion groove 30B ′) of two adjacent LED modules 10 ′. ) Are connected to both ends of the cable 77 ′, and one end of the cable 77 ′ is connected to the cable anode contact 105 (elastically deforming portion 102) inside the anode side cable insertion hole 69A (and the anode side cable insertion groove 30A ′). ) And the other end of the cable 77 ′ is connected to the cable cathode contact 95 (elastically deforming portion 96). That is, many LED modules 10 'are connected in series.
The luminaire 80 ′ includes a base member 81 and a chassis 82 (heat radiating member) (not shown in FIG. 21), and the connection body of many LED modules 10 ′ is the same as in the first embodiment. It is attached to '. Further, the lower surface of the base member 81 is covered with a channel-shaped light projecting cover member 84 ′ that covers the lower surface of the base member 81 and the LED module 10 ′ (only the upper surface opens).
When the switch (not shown) is switched from OFF to ON, the current generated by the power source flows to the electric circuit of the substrate 71 ′ via the cable 77 ′, the cathode-side conductive member 90, and the anode-side conductive member 100, and each LED 74 ′. Emits light. On the other hand, when the switch is switched from ON to OFF, the supply of current to the LED 74 'is cut off, and thus each LED 74' is turned off.

In the present embodiment described above, the anode-side cable insertion hole 69A (and the anode-side cable insertion groove 30A ′) and the cathode are formed only on the rear surface (cable connection surface comprising a flat surface) of each LED module 10 ′ (LED holder 15 ′). A side cable insertion hole 69B (and cathode side cable insertion groove 30B ′) is formed. Therefore, when attaching / detaching each cable 77 ′ to / from the LED module 10 ′, the anode-side cable insertion hole 69A, the anode-side cable insertion groove 30A ′, and the cathode-side cable from one surface side (rear side) of the LED module 10 ′. Since each cable 77 ′ may be attached to and detached from the insertion hole 69B and the cathode side cable insertion groove 30B ′, the LED module 10 ′ (the anode side cable insertion hole 69A, the anode side cable insertion groove 30A ′, and the cathode side cable insertion hole). Each cable 77 ′ can be easily attached to and detached from 69B and the cathode side cable insertion groove 30B ′).
Furthermore, each LED module 10 '(LED holder 15') has the rear surface (cable connection surface made of a plane) of each LED holder 15 'oriented in the same direction (the cable connection surface of adjacent LED modules 10'). The LED modules 10 'can be connected in a straight line without facing each other. For this reason, the operator does not need to put a hand (finger) between the opposing surfaces of the adjacent LED modules 10 ′ when attaching and detaching the cable 77 ′, so the interval (connection pitch) between the adjacent LED modules 10 ′ is shortened. However, it is possible to connect each LED module 10 'linearly.
Further, from above the insulator 20 ′, the substrate 71 ′ located directly below the index viewing hole 29 can be viewed through the index viewing hole 29 and the substrate exposure opening 62 ′ of the cover member 60 ′. The adjacent index 29A can be visually recognized. In particular, in the present embodiment, the index viewing hole 29 is provided in the vicinity of the anode side cable insertion hole 69A and the anode side cable insertion groove 30A ′, and the cathode side cable insertion hole 69B and the cathode side cable insertion groove 30B ′ (index viewing hole). And the cathode side cable insertion hole 69B and the cathode side cable insertion groove 30B ′ are arranged on the left side of the illumination opening 21 ′). The operator attaches each cable 77 ′ to the anode side cable insertion hole 69A and the anode side cable insertion groove 30A ′, and the cathode side cable insertion hole 69B and the cathode side cable insertion groove 30B ′. The indicator 29A can be visually recognized at the same time. Therefore, when the anode side index 76 can be viewed through the index viewing hole 29 and the substrate exposure opening 62 ′ (when the anode side index 76 is exposed to the outside), the insulator 20 ′ of the LED unit 70 ′ (substrate 71 ′). It can be recognized that the attachment angle (attachment position) with respect to is a regular attachment angle (attachment position) (the anode 73A is in contact with the anode contact 106 for LED of the anode-side conductive member 100). On the other hand, when the anode side index 76 cannot be viewed through the index viewing hole 29 and the board exposure opening 62 ′, the mounting angle (mounting position) of the LED unit 70 ′ (board 71 ′) with respect to the insulator 20 ′ is normal. It can be recognized that the mounting angle (mounting position) is shifted by 180 ° (the cathode 72A is in contact with the anode contact 106 for LED of the anode side conductive member 100).
Further, since the anode side indicator 28A and the cathode side indicator 28B are provided on the upper surface of the insulator 20 ', the operator can use the anode side cable insertion groove 30A' (anode side cable insertion hole 69A) and the cathode side cable insertion groove 30B '( It is possible to reliably recognize which of the cathode side cable insertion holes 69B is a hole connected to the cable cathode contact 95 (cable anode contact 105).

As mentioned above, although this invention was demonstrated based on said each embodiment, this invention is not limited to the said embodiment, It can implement, giving various deformation | transformation.
For example, the case body having the insulators 20 and 20 ′ and the cover members 60 and 60 ′ is integrally formed by insert molding in which the anode side conductive members 40 and 100 and the cathode side conductive members 50 and 90 are placed in the mold. Also good.
The elastic deformation pieces 38 and 38 ′ (engaging claws 39 and 39 ′) may be formed on the cover members 60 and 60 ′ instead of the insulators 20 and 20 ′.
Further, a heat transfer sheet or the like may be interposed between the lower surface of the substrates 71 and 71 ′ and the chassis 82. In this way, the substrates 71 and 71 ′ and the engaging claws 39 and 39 ′ are separated from each other, but the pressing force on the substrates 71 and 71 ′ from the LED cathode contacts 51 and 99 and the LED anode contacts 55 and 106 disappears. Therefore, the continuity between the anodes 72 and 73A and the cathodes 73 and 72A, the LED anode contacts 55 and 106, and the LED cathode contacts 51 and 99 is maintained.
When the lower surfaces of the substrates 71 and 71 ′ are engaged with the engaging claws 39 and 39 ′, the lower surfaces of the substrates 71 and 71 ′ are below the substrate exposure openings 62 and 62 ′ (the lower surfaces of the substrate portions 61 and 61 ′). The length of the elastically deformable pieces 38, 38 ′ (positions of the engaging claws 39, 39 ′) may be set so as to protrude into In this way, when the LED modules 10 and 10 ′ are fixed to the base member 81, the lower surfaces of the substrates 71 and 71 ′ can be more reliably brought into contact with the chassis 82.
The cable anode contacts 47A and 105, the cable cathode contacts 47B and 95, the LED cathode contacts 51 and 99, and the LED anode contacts 55 and 106 may be separated from each other.
Further, the number of the LEDs 74 and 74 ′ placed on the substrates 71 and 71 ′ is plural, and the LED modules 10 and 10 ′ (LED holders 15 and 15 ′) are different from the lighting fixtures 80 and 80 ′. It may be used as a part.

In addition, a cathode side index (for example, an index consisting of a character “−”) is provided in place of the anode side index 76, and the cathode 72A is positioned in the vicinity of the cathode side index, whereby the LED unit 70 ′ ( When the mounting angle (mounting position) of the substrate 71 ′) with respect to the insulator 20 ′ is a normal mounting angle (mounting position), an index viewing hole (a hole corresponding to the index viewing hole 29) formed in the insulator 20 ′ and The cathode side index may be visually recognized through the substrate exposure opening 62 ′ (the operator can recognize that the cathode 72A is in contact with the LED cathode contact 99 of the cathode side conductive member 90). At this time, the insulator 20 ′ is provided with an index (equivalent to the index 29A) (consisting of, for example, the character “−”) in a form adjacent to the index viewing hole (in the vicinity of the index viewing hole). Is preferred.
Furthermore, you may connect LED module 10 and 10 'of said each embodiment in a parallel state. FIG. 22 is a schematic diagram in which a large number of LED modules 10 of the first embodiment are connected in parallel.
