JP, 2014-3009, A

  In the lighting fixture disclosed in Patent Document 1, the heat sink having a heat dissipation function also functions as a substrate attachment member for attaching the LED substrate. At this time, since the substrate attachment member is in contact with the entire back surface of the LED substrate, the entire length of the substrate attachment member is configured to match the entire length of the LED substrate. Therefore, the weight of the substrate attachment member accounts for a large proportion of the total weight of the luminaire, which hinders the weight reduction of the luminaire.

It is a figure which shows the other shape of the board | substrate attachment member in embodiment of this indication. It is a figure which shows the internal structure of the conventional lighting fixture.

  Hereinafter, each embodiment will be described in detail with reference to the drawings. In the following description, the illumination direction of the luminaire, specifically, the direction perpendicular to the light emission surface of the light source is defined as the Z direction. Further, an X direction and a Y direction perpendicular to each other are defined in a plane perpendicular to the Z direction, and the longitudinal direction of the lighting apparatus is defined as the X direction.

  First, the configuration of the lighting apparatus according to the present embodiment will be described. FIG. 1 is a perspective view showing the appearance of a luminaire 10 according to an embodiment of the present disclosure. The luminaire 10 is a luminaire that can be used indoors and outdoors, and has an elongated light emitting surface and a generally elongated shape. In particular, the luminaire 10 can be employed in a refrigerated / freezed showcase or the like used in a store or the like that handles foods and beverages.

  The lighting fixture 10 has a cover 18 that accommodates an LED substrate or the like inside, a first cover 20 that covers one end of the cover 18, and a second cover 22 that covers the other end of the cover 18 as a configuration visible from the outside. And

  The cover 18 has a straight pipe shape and is formed of a translucent material such as a resin. The specific shape of the cover 18, particularly the cross-sectional shape will be described later. The cover 18 allows the light emitted from the internal LED to be transmitted to the outside, and forms the appearance of the luminaire 10 as a light emission surface. Moreover, when the lighting fixture 10 is installed in a refrigeration and freezing showcase, the cover 18 protects components, such as a LED board, from cold air.

  The first lid 20 and the second lid 22 are formed of a material such as resin, and are attachable to and detachable from the cover 18. An electric wire 24 connected to an external power supply is attached to one of the lids, for example, the first lid 20. One end of the electrical wiring 24 is connected to the LED substrate inside the cover 18 or the first lid 20.

  FIG. 2 is a perspective view showing an internal configuration of the lighting apparatus 10. FIG. 2 shows a disassembled state of the lighting device 10 in which the cover 18 is pulled out in the longitudinal direction from the first lid 20 instead of the usage state of the lighting device 10 shown in FIG. 1. FIG. 3 is a cross-sectional view of the luminaire 10 corresponding to the III-III cross section shown in FIG.

  The luminaire 10 includes an LED substrate and a substrate attachment member 16 as an internal configuration. Here, a plurality of LED substrates may exist. Therefore, the lighting fixture 10 includes at least two LED substrates of the first LED substrate 14a and the second LED substrate 14b (see FIG. 4). The first LED board 14a and the second LED board 14b have the same shape and the same configuration, respectively. Therefore, the shape and configuration will be described below by taking the first LED substrate 14a as an example.

  The first LED substrate 14 a is a substrate extending in the longitudinal direction. A plurality of LEDs 12 as light sources are mounted on the surface 140 of the first LED substrate 14a at predetermined intervals along the longitudinal direction. In addition, although LED is employ | adopted as an example of a light source in this embodiment, it is also possible to employ | adopt light emitting elements other than LED. Moreover, on the surface 140, although several LED12 shall be arranged in 1 row along a longitudinal direction, it is good also as what is arranged in parallel along a longitudinal direction.

  In addition, the first LED substrate 14 a has a through hole 141 penetrating between the front surface 140 and the back surface 148 in the vicinity of each of the end portions 142 and 143 in the longitudinal direction. The through holes 141 are, for example, formed at an intermediate position between any adjacent LEDs 12 in accordance with the arrangement of the LEDs 12.

  The substrate attachment member 16 enables attachment of one or both of the first LED substrate 14 a and the second LED substrate 14 b, and is held in contact with the cover 18. In the present embodiment, there are two types of substrate mounting members 16: a first substrate mounting member 16a and a second substrate mounting member 16b.

  FIG. 4 is a perspective view showing a state in which the first LED substrate 14a or the second LED substrate 14b is attached to the first substrate attachment member 16a and the second substrate attachment member 16b.

  The first substrate attachment member 16a enables attachment of each of the first LED substrate 14a and the second LED substrate 14b. That is, the first substrate mounting member 16a is attached in a state where the end 143 of the first LED substrate 14a and the end 144 of the second LED substrate 14b are close to each other, the first LED substrate 14a and the second LED substrate 14b It can also be said that it is a substrate connecting member for connecting in series. That is, in the lighting device 10, if the plurality of first substrate mounting members 16a are used, not only the first LED substrate 14a and the second LED substrate 14b, but also three or more LED substrates can be connected in series.

  The second substrate attachment member 16 b enables attachment of the LED substrate closest to either the first lid 20 or the second lid 22. Here, referring to FIGS. 2 and 4, the LED substrate closest to the first lid 20 is the first LED substrate 14 a. At this time, the second substrate attachment member 16b attaches the vicinity of the end portion 142 on the first lid portion 20 side of the first LED substrate 14a. That is, in the luminaire 10, the attachment of the end of the LED substrate in the vicinity of the first lid 20 and the attachment of the end of the LED substrate in the proximity of the second lid 22 There are two second substrate mounting members 16b that

  FIG. 5 is a perspective view showing the shape of the substrate attachment member 16.

  FIG. 5A is a view showing the shape of the first substrate attachment member 16 a. The first substrate attachment member 16a is a plate represented by the length L1, the width W2 and the thickness T in the longitudinal direction as a whole, and is formed of a material such as a resin. The first substrate mounting member 16a has, on the surface 30a thereof, two locking pins of a first locking pin 32a and a second locking pin 32b, and a first regulating member including a first wall 36a and a second wall 36b. And a second restricting member including a first wall 38a and a second wall 38b.

As shown in FIG. 4, the first stop pin 32a engages with the through hole 141 on the end portion 143 side formed in the first LED substrate 14a. Referring to FIG. 3, the first stop pin 32 a includes a shaft 32 a ₁ erected from the surface 30 a and two claws 32 a ₂ and 32 a ₃ connected so as to face each other at the tip of the shaft 32 a _1. Have. According to this structure, when the first stop pin 32a is engaged with the through hole 141, the two claws 32a ₂ and 32a ₃ deform so as to approach each other according to the opening diameter of the through hole 141. The inside of the through hole 141 is advanced. Then, when the front surface 30a of the first substrate mounting member 16a comes in contact with the back surface 148 of the first LED substrate 14a, the two claws 32a ₂ and 32a ₃ completely pass through the through holes 141 and return to the original shape . Thereby, detachment | leave from the 1st board | substrate attachment member 16a of 1st LED board 14a is suppressed.

  As shown in FIG. 4, the second stop pin 32b engages with the through hole 141 on the end 144 side formed in the second LED substrate 14b. The shape of the second locking pin 32b is the same as that of the first locking pin 32a.

  Here, the installation positions of the first locking pin 32a and the second locking pin 32b on the surface 30a of the first substrate mounting member 16a are the through holes 141 formed in advance in the first LED board 14a and the second LED board 14b. It depends on the position. That is, when the first LED board 14a and the second LED board 14b are attached to the first board attachment member 16a, the installation position is the through hole 141 adjacent to the end 143 or the end 144 as shown in FIG. It is decided to fit the position of. In addition, the length L1 of the first substrate mounting member 16a is at least the length required in accordance with the installation positions of the first locking pin 32a and the second locking pin 32b determined based on the position of the through hole 141. Defined to allow for As a result, the length L1 of the first substrate mounting member 16a is shorter than any of the lengths of the first LED substrate 14a or the second LED substrate 14b. Therefore, the first substrate mounting member 16a contacts only a partial region of the back surface 148 including the through hole 141 with respect to either the first LED substrate 14a or the second LED substrate 14b, and the entire back surface 148 Does not touch.

The first regulating member, the 1LED substrate 14a is suppressed from rotating displacing the shaft portion 32a ₁ of the first locking pin 32a as a rotation axis. As shown in FIG. 3, the first wall portion 36a and the second wall portion 36b constituting the first regulating member are installed such that the distance W3 between the inner walls facing each other is slightly larger than the width W1 of the first LED substrate 14a. Be done. Thus, even as the 1LED substrate 14a tries to rotate the shaft portion 32a ₁ as a rotation axis, or side 145 of the 1LED substrate 14a is in contact with the inner wall of the first wall portion 36a, or, sides of the 1LED substrate 14a The portion 146 contacts the inner wall of the second wall 36 b. Therefore, large rotational displacement of the first LED substrate 14a is suppressed. Although the length in the longitudinal direction of the first wall portion 36a and the second wall portion 36b is arbitrary, it is desirable to be as short as possible from the viewpoint of weight reduction and the like.

The second restricting member suppresses the rotational displacement of the second LED substrate 14 b with the shaft portion 32 a ₁ of the second locking pin 32 b as a rotation axis. The suppression principle of the rotational displacement of the second LED substrate 14b by the second restriction member is similar to that of the first restriction member.

  First, the width W2 of the first substrate mounting member 16a is larger than the width W1 of the first LED substrate 14a or the like in order to secure an area in contact with the rear surface 148 of the first LED substrate 14a or the like on the surface 30a.

  Also, as shown in FIG. 3, the cover 18 has a deformed annular cross-sectional shape. Specifically, the cover 18 forms therein a space S1 for receiving the light emitted from the LED 12 and diffuses the light to the outside by the diffusion portion 18a, and the holding portion 18b holding the first substrate attachment member 16a. Including. In particular, the cross-sectional shape of the holding portion 18b can be fixed to the straight pipe shaped cover 18 by simply inserting the first substrate mounting member 16a having the first LED substrate 14a attached thereto. It is desirable that the mounting member 16a be able to be held by friction. Therefore, the holding portion 18b has a first protrusion 18c in contact with the front surface 30a of the first substrate attachment member 16a and a second protrusion 18d in contact with the back surface 30b of the first substrate attachment member 16a. According to this configuration, the first substrate mounting member 16a after being inserted into the cover 18 is held in contact with the cover 18 by being sandwiched between the first projecting portion 18c and the second projecting portion 18d. Therefore, secondly, the width W2 of the first substrate attachment member 16a is sandwiched between the first protrusion 18c and the second protrusion 18d on the side portions 145 and 146 of the first substrate attachment member 16a, respectively. Let the area be a securable value.

  On the other hand, first, the thickness T of the first substrate mounting member 16a is set to a value such that the strength can be obtained so as not to break even if the first LED substrate 14a or the like is held. Second, the thickness T of the first substrate mounting member 16a is a value that allows the cover 18 to be held in contact by being sandwiched between the first projecting portion 18c and the second projecting portion 18d.

  Further, the shapes of the end portions 34 and 35 in the longitudinal direction of the first substrate mounting member 16 a are each tapered. With this shape, when inserting the first substrate mounting member 16a into the cover 18, the first substrate mounting member 16a can easily enter between the first projecting portion 18c and the second projecting portion 18d.

  In addition, the shape of the back surface 30b of the 1st board | substrate attachment member 16a will not be specifically limited if the above conditions can be satisfy | filled.

  FIG. 5B is a view showing the shape of the second substrate attachment member 16 b. The second substrate attachment member 16b is a plate represented by the length L2, the width W2 and the thickness T in the longitudinal direction as a whole, and is formed of a material such as a resin. The second substrate mounting member 16b includes, on the surface 40a thereof, a locking pin 42, a first regulating member including a first wall 46a and a second wall 46b, a first wall 48a and a second wall 48b. And a second restricting member.

  Here, the width W2 and the thickness T of the second substrate mounting member 16b are the same as the width W2 and the thickness T of the first substrate mounting member 16a. On the other hand, since the second substrate mounting member 16b targets only one LED substrate, the length L2 of the second substrate mounting member 16b is shorter than the length L1 of the first substrate mounting member 16a. Good.

  The shape of the locking pin 42 is the same as the shape of the first locking pin 32a and the like. Further, as described above, since the second substrate mounting member 16b targets only one LED substrate, the installation position of the locking pin 42 in the longitudinal direction on the surface 40a is also arbitrary.

  Further, the first restricting member and the second restricting member of the second substrate mounting member 16b are also configured and arranged on the surface 40a in comparison with the first restricting member and the second restricting member of the first substrate mounting member 16a. And, the suppression principle of rotational displacement is the same. Furthermore, it is desirable that the shape of the end portions 44 and 45 in the longitudinal direction of the second substrate mounting member 16b be tapered as in the shape of the end portions 34 and 35 of the first substrate mounting member 16a.

  FIG. 6 is a perspective view showing the shape of the substrate attachment member 50 in place of the substrate attachment member 16.

  FIG. 6A shows a state in which the substrate mounting member 50 is used to function as a substrate connecting member for connecting the first LED substrate 14a and the second LED substrate 14b, similarly to the first substrate mounting member 16a. FIG. The substrate attachment member 50 is a plate represented by the length L3 in the longitudinal direction, the width W2 and the thickness T as a whole, and is formed of a material such as a resin.

  Here, the substrate attachment member 50 differs from the first substrate attachment member 16 a mainly in that it has a notch 52 formed at any position in the longitudinal direction and along the width direction. The thickness of the notch 52 is thinner than the thickness T of the entire substrate mounting member 50.

  The substrate attachment member 50 includes a first portion 50 a and a second portion 50 b with the notch 52 as a boundary. With respect to the length L3 of the substrate attachment member 50 in the longitudinal direction, the length of the first portion 50a is represented by L4, and the length of the second portion 50b is represented by L5.

  The first portion 50a has, on the surface 60a thereof, a first restricting member including a first locking pin 62, a first wall 66a and a second wall 66b, a first wall 68a and a second wall 68b. And a second restricting member. Among these, the shape of the first stop pin 62 is the same as the shape of the first stop pin 32 a and the like. Further, as to the first restricting member and the second restricting member of the first portion 50a, compared with the first restricting member and the second restricting member of the first substrate mounting member 16a, the configuration and the suppression principle of rotational displacement are And so on. Furthermore, it is desirable that the shape of the end 64 in the longitudinal direction of the first portion 50a be tapered similarly to the shape of the end 34, 35 of the first substrate mounting member 16a.

  The second portion 50b has a first stop member 72, a first restricting member including a first wall 76a and a second wall 76b, a first wall 78a and a second wall 78b on the surface 70a. And a second restricting member. Among these, the shape of the first stop pin 72 is the same as the shape of the first stop pin 32a and the like. Further, as to the first restricting member and the second restricting member of the second portion 50b, compared with the first restricting member and the second restricting member of the first substrate mounting member 16a, the configuration and the suppression principle of rotational displacement are And so on. Furthermore, it is desirable that the shape of the end portion 74 in the longitudinal direction of the second portion 50b be tapered similarly to the shape of the end portions 34 and 35 of the first substrate mounting member 16a.

  Here, the installation positions of the first locking pin 62 and the first locking pin 72 on the surface 60a or the surface 70a are formed in advance on the first LED substrate 14a and the second LED substrate 14b, similarly to the first substrate attachment member 16a. Depends on the position of the through hole 141. That is, the installation position may be determined in the same manner as determining the installation positions of the first locking pin 32a and the second locking pin 32b in the first substrate mounting member 16a. Further, the length L3 of the substrate mounting member 50 is also defined to allow the minimum required length in accordance with the installation positions of the first locking pin 62 and the first locking pin 72. Therefore, with reference to the first stop pin 62 and the first stop pin 72, the notch 52 is formed to cross the region between the first stop pin 62 and the second stop pin 72. It can be said that

  FIG. 6B is a view showing a state in which the substrate attachment member 50 is divided with the notch 52 as a fracture region. The thickness T1 of the notch 52 is thinner than the thickness T of the entire substrate attachment member 50 as described above. Therefore, while holding the second portion 50b, the worker applies a force to the first portion 50a as shown in the arrow direction, thereby breaking the substrate attachment member 50 from the portion of the notch 52, and the first portion 50a and the second portion 50b can be separated. The first portion 50a and the second portion 50b thus divided both have shapes similar to the second substrate attachment member 16b. That is, either the first portion 50a or the second portion 50b divided can be used in the same manner as the second substrate attachment member 16b.

  The end 52a on the side of the first portion 50a and the end 52b on the side of the second portion 50b of the end which was the notch 52 before division are based on the notch shape of the notch 52. Naturally, it becomes tapered. Therefore, there is no need to taper each end 52a, 52b after division.

  Next, in order to compare with the lighting fixture 10 which concerns on this embodiment, the structure of the conventional lighting fixture 100 is demonstrated.

  FIG. 7 is a perspective view showing an internal configuration of the lighting fixture 100. As shown in FIG. In addition, in FIG. 7, the same code | symbol is attached | subjected to what can be set as the structure same as the lighting fixture 10, and description is abbreviate | omitted. Moreover, in FIG. 7, the disassembled state of the lighting fixture 100 which pulled out the cover 18 from the 1st cover part 20 to the longitudinal direction is shown similarly to FIG. 2 which concerns on this embodiment.

  Here, it is assumed that the configuration and the shape of the first LED substrate 14a on which the plurality of LEDs 12 are mounted and the cover 18 are the same as those in the present embodiment. On the other hand, the luminaire 100 particularly includes a substrate mounting plate 110 formed of a material such as a zinc steel plate and having a length that matches the entire length of the LED substrate such as the first LED substrate 14a.

  The substrate mounting plate 110 mounts the first LED substrate 14a on its surface. Here, although not shown in FIG. 7, through holes 141 for attaching the LED substrates are formed in advance in the first LED substrate 14a as described in the description of the above-described embodiment. And conventionally, the 1st LED board 14a was attached to the board | substrate attachment plate 110 by the fastening by the screw | thread 120 using the through-hole 141. As shown in FIG.

  The substrate mounting plate 110 is inserted into the cover 18 and held in contact with the cover 18 by being sandwiched between the first projecting portion 18 c and the second projecting portion 18 d. Therefore, it is desirable that the width of the substrate mounting plate 110 be a value that can ensure an area between the first protrusion 18 c and the second protrusion 18 d. For example, the width W 2 of the first substrate mounting member 16 a It may be the same.

  Next, the effects of the lighting apparatus 10 will be described.

  The lighting fixture 10 according to the present embodiment includes a substrate on which light sources are arranged in the longitudinal direction, a substrate attachment member 16 for attaching the substrate, and a cover 18 for holding the substrate attachment member 16 in contact. The substrate has a through hole 141 adjacent to the longitudinal end. The substrate attachment member 16 contacts a partial area including the through hole 141 of the substrate.

  Here, the light source is, for example, an LED 12. In this case, the substrate is an LED substrate such as the first LED substrate 14a or the second LED substrate 14b.

  Conventionally, as shown in FIG. 7, for mounting of the LED substrate, a substrate mounting plate 110 having a length matching the entire length and made of a material such as a zinc steel plate has been used. Therefore, the weight of the substrate mounting plate 110 accounts for a large proportion of the total weight of the luminaire 100. On the other hand, according to the luminaire 10 according to the present embodiment, the substrate mounting member 16 contacts only a region including the through holes 141 that can be used for fixing or engaging the LED substrate instead of the substrate mounting plate 110. Is used. The length L 1 in the longitudinal direction of the substrate attachment member 16 thus defined is shorter than the length in the longitudinal direction of the conventional substrate attachment plate 110. As a result, the weight of the substrate attachment member 16 is reduced compared to the substrate attachment plate 110, and as a result, the weight reduction of the entire luminaire 10 is realized.

  In addition, according to such weight reduction, for example, the material cost of the substrate attachment member is suppressed, and as a result, it also contributes to the suppression of the manufacturing cost of the lighting fixture 10. Moreover, although the conventional board | substrate attachment plate 110 was what is called a sheet metal component, weight reduction can be achieved more by making the substrate attachment member 16 in this embodiment into a resin component.

  On the other hand, it is also conceivable to simply remove the substrate mounting plate 110 from the conventional lighting fixture 100 for the purpose of weight reduction. However, since the width W1 of the LED substrate is shorter than the width W2 of the substrate mounting plate 110, the LED substrate 14 can not reach the first protrusion 18c and the second protrusion 18d of the cover 18. That is, in this case, when the shape of the cover 18 is previously defined, it can not respond. On the other hand, according to the present embodiment, since the substrate mounting member 16 can secure the width W2 to such an extent that it is held in contact by the cover 18, even when the shape of the cover 18 is prescribed in advance It is possible.

  Moreover, in the lighting fixture 10 which concerns on this embodiment, the board | substrate attachment member 16 has a stop pin which engages with the through-hole 141 and suppresses detachment | leave of a board | substrate.

  According to the luminaire 10 according to the present embodiment, for example, when the LED substrate is existing, the substrate attachment member 16 utilizes the screw hole already formed in the LED substrate as the through hole 141 to use the LED substrate It can be attached. That is, this embodiment can be applied to a lighting fixture that uses an existing LED substrate as well as the cover 18. In other words, it is not necessary to newly manufacture the cover 18 or the LED substrate in order to apply the present embodiment.

  Further, by providing the fixing pins directly on the substrate attachment member 16, the substrate attachment member 16 can easily attach the LED substrate without using a separate screw.

  Moreover, in the lighting fixture 10 according to the present embodiment, the substrate includes the first substrate and the second substrate. At this time, the substrate attachment member engages with the through hole formed in the first substrate and engages with the through hole formed in the second substrate. And a second locking pin for preventing detachment of the substrate. The substrate attachment member couples the first substrate and the second substrate in the longitudinal direction.

  Here, the first substrate is, for example, the first LED substrate 14a. The second substrate is, for example, a second LED substrate 14b. In particular, the substrate attachment member in this case corresponds, for example, to the first substrate attachment member 16a, the first stop pin corresponds, for example, to the first stop pin 32a, and the second stop pin, for example, the second stop. It corresponds to the pin 32b.

  According to the luminaire 10 according to the present embodiment, even if there are a plurality of LED substrates in the luminaire 10, the substrate attachment member can connect the LED substrates along the longitudinal direction. Thus, for example, the worker can easily insert and remove the substrate attachment member with respect to the cover 18.

  Moreover, in the lighting fixture 10 which concerns on this embodiment, when the board | substrate attachment member 16 is erected along the longitudinal direction of a board | substrate on the surface which attaches a board | substrate, and the stop pin is engaged with the through-hole 141. The side wall of the substrate has an opposing inner wall.

  Here, assuming that the substrate mounting member 16 is the first substrate mounting member 16a, for example, the locking pin corresponds to the first locking pin 32a, and the wall portion is the first wall portion 36a constituting the first regulating member. And the second wall 36 b.

As described above, in the state where the first stop pin 32a into the through hole 141 is engaged, for example, conceivable that the first 1LED substrate 14a of the shaft portion 32a ₁ of the first locking pin 32a as a rotation axis is rotationally displaced Be On the other hand, according to the luminaire 10 according to the present embodiment, even if the first LED substrate 14a is about to be rotationally displaced in this way, either of the side portions of the first LED substrate 14a and the first wall portion 36a or the second One of the inner walls of the wall portion 36b contacts. Therefore, the rotational displacement of the first LED substrate 14a is suppressed. As a result, the posture of the LED substrate with respect to the substrate mounting member 16 is further stabilized, so that insertion and removal of the substrate mounting member by the operator becomes easier.

  Furthermore, in the luminaire 10 according to the present embodiment, the substrate attachment member 50 has a notch 52 that crosses the area between the first locking pin 62 and the second locking pin 72.

  According to the luminaire 10 according to the present embodiment, it is not necessary to prepare two types of substrate mounting members, one for connecting two LED substrates and one for simply mounting one LED substrate. That is, according to this configuration, when the two LED substrates are used to be connected, the substrate attachment member 50 is used as it is. On the other hand, when only one LED substrate is used for mounting, the substrate mounting member 50 is divided into two from the notch 52, and either the divided first portion 50a or the second portion 50b is used. Just do it.

  As mentioned above, although a preferable embodiment was described, this embodiment is not limited to this, A various modification and change are possible within the limits of the gist.
