Description

Recessed type marker lamp installation device and recessed type marker lamp device

technical field

The present invention relates to a built-in marker lamp installation device for installing marker lamps used for aircraft navigation in airports, etc.

Background technique

As a structure for installing embedded marker lights for airports on the road surface, a base is buried on the road surface in advance, and the embedded marker light is mounted directly on the base or indirectly through an adjustment ring. In addition, wiring for connecting the power supply and other embedded marker lights is carried out in advance in the base. As for the construction method of electrical wiring, there are cutting and bonding method and piping method.

The former is a work method in which a wiring duct is cut out of the concrete constituting the road surface, and electrical wiring is directly bonded in the wiring duct. The base used in this working method is installed with waterproof connection terminals through its side, and the power terminal block is arranged on the inner side of the base, and the connection between the power terminal block and the connection terminals is made by the internal connection wire. connected structure. In contrast, in the recessed marker lamp, the power receiving terminal protrudes from the bottom surface, and the power receiving terminal is connected to the power terminal base when the recessed marker lamp is placed at a predetermined position on the base.

The latter is the work method of threading and wiring in the pipes. It is laid in the concrete constituting the road surface in advance, the pipes with the wiring inside are connected to the base, and the wiring is introduced into the inside of the base. The front end of the wiring is connected to a socket. On the other hand, in the recessed type marker lamp, the connection wire is pulled out from the bottom surface, and the plug is connected to the front end of the connection wire. Then, the plug is attached to the socket, and the embedded marker lamp is connected to the wiring.

However, there are problems in any wiring method. That is, in the cutting and bonding method, although there is no problem described later in the piping method, it is easy to cut the wiring in the wiring duct during foundation construction, and there is a problem of lack of long-term reliability. The piping method was developed as a countermeasure against this problem.

On the other hand, in the piping work method, since rainwater may enter along the piping, it is necessary to tie it with a tape after connecting the plug to the socket when installing the recessed marker light. Therefore, the replacement work of the embedded type marker lamp is time-consuming, and it is difficult to replace it in a short time. On the other hand, in airports, there is a strong demand for the maintenance of embedded marker lights to be completed in a short time, so there is a problem that the marker lamp installation devices used in the conventional piping work method cannot meet the above-mentioned requirements.

It is an object of the present invention to provide a recessed marker lamp installation device which has excellent long-term reliability and which can replace the recessed marker lamp in a short time, eliminating the disadvantages of the conventional ones, and a recessed marker lamp device having the same.

In addition, another object of the present invention is to provide a recessed marker lamp device having an improved recessed marker lamp based on the above.

Summary of the invention

The embedded marker light installation device of the invention of claim 1 is characterized by comprising: a base having an open end formed on the upper surface, a socket connected to the wiring in the pipe is housed inside, and buried in the road surface; It includes an adapter body that accommodates the recess of the embedded marker lamp and is installed on the open end of the base, a power terminal block that is exposed to the inner surface of the recess of the adapter body and connected to the power receiving terminal of the embedded marker lamp, and a secondary power terminal block. An adapter with a plug drawn out to the back of the adapter body and connected to a socket in the base.

In the present invention and the following inventions, the definitions and technical meanings of terms are as follows.

First, the base will be described. In the present invention, the base is embedded in the road surface, and at the same time, wiring is introduced, and a foundation for installing the embedded marker light is provided. That is, the recessed marker light is directly or indirectly attached to the base via an adapter. Therefore, the base is firstly a structure suitable for the piping method. Specifically, it has a structure that can be connected to a pipe. Connections to piping are best made using the sides of the base, but the bottom can also be used if desired.

In addition, openings are made on the top of the base in order to provide a base for mounting the recessed marker light. Furthermore, the adapter is directly or indirectly attached via an adjustment ring. For the installation of the adapter, it is best to use the opening, but if necessary, it can also be a part other than the opening such as the side. In addition, for the installation of the adapter, a screw hole is formed at an appropriate position of the opening end of the base, and a through hole consistent with the screw hole is formed on the adapter, so that the bolt can be screwed into the screw hole through the through hole. However, if necessary, it is also possible to form a through hole through which the stud bolt protrudes from the opening end of the base, and the stud bolt is inserted into the adapter, and the nut is screwed into the stud bolt from the adapter to form a fixed adapter on the adapter. structure on the base.

In addition, in order to supply power to the embedded marker light, a socket connected to the wiring in the piping is housed inside the base. The socket is connected to a plug drawn from an adapter described later.

Next, the adapter will be described. In the present invention, the adapter is interposed between the base and the recessed marker lamp, and the power connection method using the piping method is converted into a better power connection method for replacing the recessed marker lamp. Therefore, the adapter has an adapter body, a power terminal block, and a plug, and has a function of mounting the adapter itself on a base, a function of mounting a recessed marker light, and a function of converting a power connection method.

In addition, the adapter main body has a concave portion for accommodating the embedded marker light on the upper surface. The concave portion is a main part that functions as an attachment for the recessed marker light. That is, the recessed marker lamp is stably supported by accommodating the protruding lower portion of the embedded marker lamp. In addition, it has a structure for fixing the embedded marker light. For example, common fixing means such as stud bolts or screw holes can be used. That is, when the recess is a stud bolt, the stud bolt protrudes upward from the adapter body, and the stud bolt is inserted through the through hole formed on the embedded marker lamp, and the stud bolt is inserted from above the embedded marker lamp. The nut is screwed in and tightened. Conversely, in the case of a screw hole, a screw hole is formed in the adapter body, a through hole is formed in the recessed marker light, and a bolt is screwed into the screw hole through the through hole and fastened.

On the other hand, the adapter body has fixing means for mounting the adapter on the base. For example, there is a mounting device corresponding to the mounting device of the base such as a through hole on the periphery, the bolt is screwed into the screw hole of the base from above the adapter body, and the double head protruding upward from the through hole of the adapter body The nut is screwed in and fastened above the bolt.

In addition, the adapter body may be either a single component or a composite component. In the latter case, the adapter body is composed of a plurality of components, but other parts of the plurality of components may be separated or combined. For example, the bottom part can be separated from other parts and can be connected with fasteners such as bolts. In this case, the inside of the base can be inspected and repaired only by separating the bottom surface without detaching the adapter main body from the base, and the above-mentioned work can be performed more easily and in a short time.

The power terminal block can be configured to be connected to a power receiving terminal protruding from the bottom of the embedded marker light, for example, when the embedded marker lamp is accommodated in the recess of the adapter body in a predetermined order. In other words, by arranging the embedded marker lamp at a predetermined position, the power supply terminal base is automatically connected to the power receiving terminal. In addition, when the embedded marker light is detached from the adapter, the power receiving terminal is automatically detached from the power terminal block. However, the correct position of the embedded marker lamp relative to the adapter can be limited by the installation means between the embedded marker lamp and the adapter. Therefore, it is best to make a When assembling them, even if there is a slight positional deviation, it can be connected, and it has a margin within the allowable range of the position, and can respond flexibly, and a relatively movable structure. In addition, when the positions of the above two are made relatively movable, it is sufficient to make either or both of them movable. If the former is made movable, the embedded marker lamp can be used as two wire Work method with universal design, so it is the best.

In addition, it is preferable that the power supply terminal block has a structure in which a connector is accommodated in an insulating case, so that the power receiving terminal of the embedded marker lamp is accommodated inside and connected. In addition, the power supply terminal block can be equipped with guide pins or guide holes in order to make the connection with the power receiving terminal easier. Of course, in accordance with this, a guide hole or a guide pin on the opposite side to the power terminal block is provided in the recessed marker lamp. That is, a desired guiding effect can be produced during the fitting process of the guide pin and the guide hole. In addition, the opening end of the guide hole has a conical conical surface around it, so that the guide pin can be guided to the guide hole.

The plug and the power terminal block cooperate to perform the conversion function of the power connection mode. Therefore, the plug is drawn out from the power terminal block to the rear side of the adapter body, and is connected to the socket in the base. The plug and the power terminal block can be directly connected by using an insulated coated wire, or can be connected indirectly through a relay terminal that penetrates the adapter body in a waterproof manner. In the former case, since the insulation-coated wire penetrates the adapter body, it is possible to perform waterproof treatment on the penetration part and insulation treatment such as disposing an insulating bushing on the penetration part. In addition, after connecting the plug and the socket of the base, reliable waterproofing can be performed even if it takes time and effort to tie both of them with a tape using an insulating tape. Also, in the latter case, it is preferable to waterproof the adapter body and install the relay terminal.

Next, the action of the present invention will be described. The recessed marker lamp installation device has the structure described above, and the replacement of the recessed marker lamp is carried out as a daily maintenance, as long as the recessed marker lamp is removed from the adapter, and a new recessed marker lamp is installed on the adapter. That's it. Because only by removing the embedded marker light, the power receiving terminal can be separated from the power supply terminal block, and the wiring can be released. In addition, as long as a new recessed marker light is installed, its power receiving terminal can be connected to the power terminal block of the adapter to form the required wiring. Therefore, the replacement work of the embedded marker lamp becomes easy and can be completed in a short time.

In addition, it is possible to configure the embedded marker light designed as the cutting and bonding method to be attached to the base for the piping method. Therefore, long-term reliability can be imparted to the wiring of embedded sign lights at airports. However, it may also be a built-in marker light designed solely for exclusive use.

The embedded type marker light installation device of the invention of claim 2 is characterized in that it has an open end formed on the upper surface, a socket connected to the wiring in the pipe is accommodated inside, and the base is embedded in the road surface; The ring-shaped lower adapter on the open end of the base; and the upper adapter body that includes a recess for accommodating the embedded marker lamp and is installed on the open end of the base through the lower adapter, and the inner surface of the recess of the upper adapter body is exposed. The upper adapter is provided with a power terminal block connected to the power receiving terminal of the embedded marker lamp and a plug drawn from the power terminal block to the back side of the upper adapter body and connected to the socket in the base.

The adapter of the present invention is different from the invention described in Claim 1 in that it is constituted by an upper adapter and a lower adapter. That is, even if the base and the lower adapter are buried in the road surface, if the embedded marker light and the upper adapter are removed, the inside of the base can be seen from above the base and the lower adapter. Therefore, the lower adapter can generally be used in a state of being embedded in the road surface together with the base. In addition, since the upper adapter is made detachable from the lower adapter, and the lower adapter is mounted on the base, the lower adapter is allowed to have a mounting device that can be mounted on the mounting portion of the base, and also has a mounting device for mounting the upper adapter. installation department. However, the lower adapter can also be sandwiched between the base and the adapter in layers. In addition, a transformer connected to the marker light can be built in the base.

Furthermore, in the present invention, by having the structure described above, even if the lower adapter is installed on the base and buried in the road surface, since the base can be seen from above the lower adapter only by removing the embedded marker light and the upper adapter, The inside of the base, so it is ideal for the occasion where the transformer is hidden in the base. That is, in the case of built-in transformers, after the base and the lower adapter are buried in the road surface, the transformer is housed inside the base, or the auxiliary equipment such as the transformer and wiring housed inside the base for maintenance is repaired. Check, when needing to change transformer, the present invention is very convenient.

The embedded marker lamp device of the invention of claim 3 is characterized in that it includes: the embedded marker lamp mounting device according to claim 1 or 2; the embedded marker lamp mounted on the adapter or the upper adapter, The buried type marker lamp includes a lamp body with a light extraction groove arranged on the upper surface, an internal space communicated with the light extraction groove, and a prism for limiting the optical path arranged between the light extraction groove and the internal space in a liquid-tight manner. The optical unit of the light source for projecting light to the prism is arranged in the inner space, and the power receiving terminal is exposed downward from the lamp body and connected to the light source.

As described above, the recessed marker light device of the present invention is composed of a recessed marker lamp and a recessed marker lamp installation device for mounting the marker lamp on a road surface. In addition, the so-called "adapter" refers to the adapter specified in claim 1. In addition, the "upper adapter" refers to the upper adapter specified in Claim 2.

First, a recessed marker lamp will be described. The structure of the recessed sign lamp has at least a lamp body, an optical unit, a power receiving terminal and an installation device. When embedded marker lights are used in airports, for example, they can be configured as taxiway center line lights, guideway center line lights, stop line lights, etc. In addition, for road use, it can be configured to be suitable for necessary uses such as use for intersection signs.

The lamp body has a light extraction groove, an inner space, a prism and a mounting part. In addition, the lamp body is preferably divided into an upper lamp body and a lower lamp body because components such as an optical unit accommodated in the internal space are incorporated. In this case, in order to make the aircraft sufficiently withstand the mechanical force when the upper part of the aircraft travels at high speed, the upper lamp body is preferably formed by casting with a durable and strong metal. On the other hand, since the lower lamp body is housed in the adapter or the upper adapter, it can be formed by stamping or die-casting a relatively weak metal plate.

The light extraction groove is disposed on the upper surface of the lamp body exposed to the road surface. In the case of such a recessed marker light, it is necessary to irradiate the marker light at a small elevation angle with respect to the road surface, so light extraction grooves are formed. The inner space is generally located in a position buried in the road surface. Furthermore, a power receiving terminal and the like of an optical unit to be described later are accommodated.

The prism refracts the light path emitted by the optical unit and is used to limit the light path to a specified elevation angle. That is, it is difficult to set the optical axis from the light source to the prism at a small angle with respect to the road surface in the inner space of the lamp body. Therefore, a prism is interposed therebetween to refract toward the road surface. For arranging the prisms at predetermined positions, it is preferable to employ the following structures. That is to say, a concave part for accommodating the prism is formed on the inner side of the lamp body, and a frame-shaped gasket made of soft elastic material such as rubber is arranged around the back part, that is, the light incident surface, and then a frame-shaped push fitting is used to Support the back of the pad. The push fitting is fixed on the inner surface of the lamp body using screw holes or the like.

The mounting part is a structure for mounting the lamp body on the adapter or the upper adapter, and is formed by using mounting holes arranged at appropriate places around the lamp body. At the upper end of the mounting hole, it is allowed to accommodate the heads of nuts or bolts, etc., and provide a recess that does not protrude from the upper face of the lamp body. In addition, the installation hole is used to adjust the installation position of the embedded marker light of the adapter or the upper adapter, so it is allowed to be a long hole. Therefore, when the upper surface of the lamp body is circular, the elongated hole is arcuate.

The optical unit has at least a light source, and may include other optical devices such as reflectors, color filters, and light reduction filters as needed, and accessory devices such as mounting frames for mounting the above-mentioned optical devices at predetermined positions. From the point of view of small size and high light output, it is better to use halogen bulbs as the light source, and bulbs filled with krypton and xenon gas can also obtain smaller size and high light output. light bulbs or light-emitting diodes, etc. In addition, when a halogen bulb is used, an infrared reflective film is formed on the surface of the bulb to further improve luminous efficiency, so this structure is ideal for the present invention.

The color filter is an optical device for selecting the wavelength of the light beam emitted on the optical path to a predetermined light color, and is arranged on the optical path between the light source and the prism. In addition, as a color filter, a dichroic filter coated with a dichroic filter film by vapor deposition on the surface of a glass plate is ideal because it can efficiently obtain only light of a desired color. In addition, the color filter is arranged at a predetermined position, for example, the color filter is supported by a metal frame, and the metal frame is fastened together with a pressing fitting of the prism.

Reflectors collect light from a light source and are used when entering a color filter. In addition, the reflector may be independent from the light source, or both may be integrated. In the latter case, a dichroic reflective film is formed on a reflective substrate surface having a quadratic surface of revolution or a plurality of divided surfaces and a glass forming base having a cylindrical portion on the top of the reflective substrate surface. The resulting reflecting mirror can be integrated by inserting the sealing portion of the bulb into the cylindrical portion, fixing the cylindrical portion and the sealing portion with an inorganic adhesive. In addition, a dichroic reflective film is preferable because it has optical characteristics of reflecting visible light and transmitting infrared light.

Dimming filter, used when the light output of recessed marker lights is larger than the allowable value. In addition, the light reduction filter is overlapped with the color filter, and is arranged so as to be supported by a metal frame that can be shared with the color filter. In addition, as the light reduction filter, a structure in which a light reduction filter film made of metal vapor deposition is coated on the surface of a glass substrate can be used.

In addition to the optical device, as an additional device, a limit frame that limits the position of the light source and the reflector can be used. The positions of the light source and the reflector are important because the light distribution characteristics specified by the optical unit are given to the recessed marker light. In addition, the light source can be installed on the lamp body by using the limiting frame. In addition, the integrated light source and reflector can be pushed from the back, and a push piece can be arranged so that the front surface can be brought into contact with the stop frame. In addition, the elastic detachment preventer can be detachably mounted on the limit frame so that even if a large impact is applied to the embedded marker lamp, the light source and the reflector will not deviate or fall off from the predetermined position.

Next, the power receiving terminal will be described. The power receiving terminal is a device connected to the power terminal block of the adapter or the upper adapter to receive power from the power source, and is arranged on the bottom or side of the embedded marker light corresponding to the position of the power terminal block of the adapter. In addition, the power receiving terminal is configured to be connectable to the power terminal base. The best structure is to correspond to the structure of the power terminal block, so that the guide hole or guide pin and the insertion blade stand upright from the insulating substrate, the guide hole or guide pin is inserted into the guide pin or guide hole of the power terminal block, and the insertion blade Connect to the connector housed inside the power terminal block.

In addition, the mounting device will be described. The mounting device is a device for mounting the recessed marker lamp to the adapter or the upper adapter, and is constituted by a mounting portion or a fixing member formed on a lamp body of the recessed marker lamp. The fixture is the structure described in technical solution 1.

Finally, the action of the present invention will be described. To mount the recessed marker light, first, the recessed marker lamp is accommodated at a predetermined position in the recess of the adapter or the upper adapter of the recessed marker lamp mounting device. Then, the power receiving terminal of the recessed marker lamp is connected to the adapter or the power supply terminal base of the upper adapter. Next, when the embedded marker light is fixed to the adapter or the upper adapter by the mounting device, the mounting is completed. What is necessary is just to carry out the reverse of the above-mentioned with respect to the detachment of the built-in recessed marker lamp after installation. Therefore, the replacement work of the embedded marker lamp is easy and can be completed in a short time.

In the embedded marker light device of the invention of claim 4, in the embedded marker lamp device of claim 3, the embedded marker lamp has a light incident surface of a prism that is exposed to the lamp body. The liner that is connected, and the pushing frame that is fixed on the lamp body and presses the prism through the liner, and the liner is mechanically combined with the pushing frame.

In the present invention, due to the strong impact exerted on the embedded marker lamp due to driving on the lamp body such as an airplane, it is stipulated to improve the structure of the arranged gasket and the pressure plate so as not to make the arrangement on the embedded sign lamp. The prism on the lamp body of the type marker lamp is not expected to fall off or shift from the specified position of the lamp body. That is, the spacer and the pressure plate are overlapped and in contact with the periphery of the light incident surface of the prism, and can be screwed to the lamp body at two places, for example.

However, deformation centered on the screw fastening part occurs, and the pressing of the gasket does not effectively act. In the high temperature state caused by the heat generated by the lighting of the light source, there is a The deformation of the liner can easily cause the problem of deflection. In addition, this tendency becomes relatively conspicuous as the lateral width of the prism increases. When the position of the above-mentioned part is shifted, the spacer covers the upper part of the light incident surface of the prism, which may cause problems such as blockage of incident light, disturbance of light distribution, or insufficient luminosity of the light beam.

Therefore, in the present invention, the gasket is not simply brought into contact with the pressing frame, but the two are mechanically coupled. The combination of the pad and the mechanism that pushes the frame can be performed at the desired location. For example, it may be configured to be mechanically bonded only to the portion greatly affected by the displacement of the gasket, or may be integrally bonded. In addition, as the mechanical connection, for example, a protrusion is partially formed on the spacer, and a recess or a through hole for fitting the protrusion and the opposing portion of the pressure plate is partially formed. However, contrary to this, the protrusions may be formed on the presser plate and the recesses may be formed on the spacer. In addition, the above two can also be combined if necessary.

Therefore, in the present invention, by mechanically coupling the spacer to the pressure plate, even if the temperature of the internal space of the lamp body rises due to the lighting of the light source, the spacer is unlikely to be displaced in an undesired position, so that the spacer is unlikely to occur. Pad deformation and out of range of the optical path of the situation.

The embedded marker lamp device of the invention of claim 5 is the embedded marker lamp device described in technical claim 3 or 4, characterized in that the embedded marker lamp has an optical unit sandwiched between a prism and a Dichroic and neutralizing filters in the light path between light sources.

The present invention defines a structure for adjusting the luminosity of the beam output of the recessed marker lamp so as to easily enter the range of the standard value. That is, in the present invention, in addition to the dichroic color filter, a light reduction filter is interposed in the optical path. Since the dichroic color filter and the light reduction filter can be placed on the prism side regardless of the front-rear relationship, it is preferable to arrange them so that they overlap or stick together. Therefore, the support structure can be simplified by using a common filter support frame. Alternatively, the supporting frame may be fastened together with the prism and the pressing frame. In addition, in the case of using a common support frame, put the two filters into the support frame, and then push the side edges of the two filters with the elastic push piece, so that the two filters can be reliably fixed with a simple structure. Support. However, when a dichroic color filter and a light reduction filter are overlapped or attached, when at least any one of these filter films is in contact with the other side, the filter film is easily damaged, so it is best to make it in a non-contact state. . Therefore, what is necessary is just to overlap or bond each filter film outward. Alternatively, a single glass substrate may be used to form a dichroic color filter on one side and a light reduction filter on the other side.

Furthermore, in the present invention, since a light reduction filter is provided in addition to the dichroic color filter, even if the light source has a large light intensity, the light intensity of the light beam output can be accommodated within a predetermined range. In addition, since the color filter has a structure of a dichroic color filter film, it is possible to easily obtain transmitted light of a desired light color in a desired wavelength range. In addition, the support structure becomes simple as long as the dichroic color filter and the light reduction filter are supported so as to overlap or stick together. In addition, damage to the filter film can be prevented by configuring the state where each filter film is not in contact with the other side.
