(Points of interest)
In recent years, LED lighting technology has been widely used in various fields as a means to reduce lighting costs and power consumption while maintaining and improving the lighting environment. Introduction to road and tunnel lighting for the purpose of cost reduction has been widely promoted. In particular, tunnel lighting has basic lighting, entrance lighting, exit lighting, and special structure lighting. There are junctions, emergency parking zones, sidewalks, etc., and the entrance and exit lighting sets the boundary, transition, and relaxation areas from high outdoor brightness to basic lighting, 10 times the basic part Designed to require a certain level of road surface brightness, lighting lamps must also have a larger rated luminous flux. To meet these requirements, higher-brightness LEDs are mounted and the number of mounted LEDs is increased. Lighting In order to realize this, it is necessary to increase the degree of freedom of the LED arrangement in the lamp housing and the heat dissipation performance. For housing lighting and special structure lighting, multiple types of housings with different dimensions must be manufactured according to the application, and preparing molds individually increases the manufacturing cost and the sales and installation price. And there was a risk that the maintenance cost would rise.

    Further, according to the installation location of the lighting lamp, the COB arrangement must be individually positioned and incorporated with sufficient durability on the mount base in the lamp housing, but the COB chip substrate is made of ceramic. In some cases, it is easily damaged by tightening and fixing with screws, and it is possible to fix it with heat-dissipating double-sided adhesive tape to prevent such damage to the chip substrate, but fine adjustment of the mounting position after sticking becomes impossible In addition, there are inconveniences such as difficult maintenance work by attaching and detaching, and when connecting the lead wire by the socket type that is easy to attach and detach to the power connection point of the COB / chip board, the deterioration of the power connection point is prevented. In order to achieve this, plating is indispensable, the price of parts rises, and the socket part is buffered by the light distribution control lens. In order to overcome such problems, when soldering is used, the power connection point of the solder connection is exposed on the surface of the chip substrate, and some insulation is required. It was supposed to be.

(Conventional technology)
Reflecting this situation, proposals that can be used to overcome this situation are not unheard of.
For example, as typified by what is proposed in Patent Document 1 (1) below, it includes a plurality of LED chips, a metal substrate that supports the plurality of LED chips, and a support member that disposes a plurality of the metal substrates. A lighting device for a tunnel in which a light source device and a power supply device are attached to a housing, wherein the support member is made of a metal plate having a convex shape in a sectional view, and is connected so as to be in contact with the back surface of the metal substrate. A heat sink made of a metal plate having a convex shape in a sectional view is attached to the back surface of the support member so as to be in thermal contact, and the heat sink and the housing are connected in thermal contact with each other. It is made up of a tunnel LED lighting heat dissipation structure that increases heat dissipation, and a metal material and a resin composition as seen in Patent Document 1 (2), and has an average thickness of 0. A metal material such as an aluminum extrusion molded product having a thickness of 2 to 2.0 mm and a resin composition having an average thickness of 0.5 mm to 3 mm and a dispersity θ of 45 degrees or more are integrally molded, There are some metal / resin composition composite moldings that are lightweight, have heat dissipation properties, and can be manufactured at low cost.

    Moreover, like the thing disclosed in the said patent document 1 (3), it can fix so that an LED light source may be inserted | pinched, and it has the lower side support body and upper side support body which have insulation, A lower side support body is light source arrangement | positioning recessed part, and And a conductive terminal that enables electrical connection to the electrode of the LED light source on the inner side of the upper support, and on the edge of the rear surface of the LED light source of the light source placement recess of the lower support A burr avoiding groove for dropping the burr on the back of the LED light source is provided at the opposite position, and the area surrounded by the burr avoiding groove in the light source arrangement recess is a flat surface that can contact the back of the LED light source. Since the LED light source is fixed by the upper support and the lower support using an insulating material, even if the substrate of the LED light source is made of metal, insulation from the LED light source to the device housing (metal) Ensure sufficient distance In addition, since it is not necessary to directly fix the LED light source with screws, there is no leakage of electricity to the housing through the screws, and further, the conductive terminal of the upper support is from above the surface electrode of the LED light source. Since the LED light source is pressed and fixed so as not to contact the substrate side surface of the LED light source that has not been insulated, the LED light source is short-circuited and does not cause a problem, as in Patent Document 1 (4) And an insulating plate, a through hole provided in the insulating plate, a metal plate accommodated in the through hole, an insulating plate provided on the insulating plate so as to cover the metal plate, and a light emitting portion. It is possible to obtain a light source with excellent luminous efficiency with good heat dissipation and a small mounting area and sufficient insulation. Such as a light-emitting unit distance so as to be secured has already been already developed.

    However, in the tunnel LED illumination heat dissipation structure as shown in the former Patent Document 1 (1), the lamp housing has a rectangular shape in which the side wall is integrally raised from the entire periphery of the bottom surface. Therefore, it is necessary to separately prepare a mold for molding the housing for each housing size depending on the lighting performance, which leaves a problem that the production cost cannot be suppressed. Although the metal / resin composition composite molded product of (2) has a cylindrical shape useful as a casing of a straight tube type LED lighting device, it is basically not decomposed by insert molding of the resin composition. Because it is possible to integrally mold the LED, if the LED is aged or damaged, the lighting device itself will be replaced. maintenance There can be used as it is in the tunnel lighting device to be emphasized were those must be said almost impossible.

In the light emitting device such as Patent Document 1 (3), the lead wire is arranged so as to contact each power supply connection point of the COB, and is electrically connected so as to be suppressed by a fixture. Therefore, it is necessary to apply a plating process to each power source connection point of the COB, and there is little track record of long-term use, and there remains a problem of lack of reliability. Patent Document 1 (4) As shown in Fig. 1, a pair of connectors enables electrical connection with each power connection point of the COB, and the COB / chip substrate is mechanically held and fixed to the insulating plate (mount base). However, even in such cases, it is still necessary to apply plating to each power supply connection point of the COB. Were those forced to not say that.

(Awareness of problems)
As seen above, many of the various LED lighting heat dissipation structures for tunnels that have been proposed so far have been reexamined in terms of heat sink shape and expanded heat dissipation area. -A plurality of lamp housing molds must be prepared, and the problem of increased manufacturing costs remains. Also, a resin having a degree of dispersion θ of 45 degrees or more on a metal material such as an aluminum extruded product. Metal / resin composition composite molded products that are integrally molded from the composition are almost impossible to disassemble and cannot be used as they are for LED lighting fixtures for tunnels that require maintenance and maintenance. In addition, the conventional COB power supply connection points are not necessarily connected with the lead wires held down by connectors or the like. However, in such a connection, when used for a long period of time, it is difficult to make a normal electrical connection due to deterioration of the contact point, which may cause deterioration of lighting performance or failure, and may cause deterioration of durability. Yes, he has been involved in the development, manufacture, provision, installation, maintenance, and maintenance of various lighting devices for many years, and has already completed and provided tunnel lighting fixtures such as Patent Documents 1 (5) and 1 (6). While continuing, based on various knowledge gained from them and information transmitted from various related fields, it is possible to replace with conventional ceramic metal hydride lamps as well as reducing manufacturing costs. However, it will solve many problems such as higher output, smaller size and lighter weight, improved heat dissipation, improved production efficiency and maintenance efficiency. With regard to the configuration enabling practical use of the LED illumination for the inlet of the light, the necessity of further improvement has been felt.

As described above, according to the light source module of the present invention, unlike the conventional ones, the pair of COB holders are mounted by the cover blades of the COB holder by the cover blades of the COB holder. Since the power connection point exposed to the surface is surrounded and covered in an insulated state, a short circuit can be surely prevented, and it can interfere with the COBLED element, the light distribution control lens, etc., and obstruct illumination light. It is possible to reduce the size and weight, and the frame wall and claw are joined to the corresponding parts such as the mounting base mounting flat wall, the regulation groove wall, and the side edge and surface wall of the mounting COB chip substrate, respectively. In addition, by fixing the mounting base to the mounting base adherent portion, the COB can be more accurately and conveniently incorporated at the desired position of the mounting base. , Ruggedized strength, yet because attachment and detachment work is also done easily, can be provided with remarkably enhanced production efficiency and maintenance efficiency.

    In addition, in the case of providing the rotation restricting piece, the posture of the frame wall is more firmly restricted by bringing the rotation restricting piece into contact with the COB chip substrate incorporated in the mount base, so that the COB chip substrate is more accurate. The posture of the frame wall, the claw and the rotation regulating piece with respect to the mount base regulating groove wall and the guide wall can be remarkably improved by providing a posture regulating frame and a posture guiding frame. Because it can be accurately regulated, the mounting position of the COB chip substrate to the mount base is firmly maintained even when external forces such as vibration and impact force are applied. The durability will be increased, the durability will be extended, the maintenance cost will be reduced, and a more economical lighting will be provided.

    The maximum wall thickness of the COB holder is limited to the thickness of the target COB chip substrate plus the height of the cover blades. When the independent light distribution control lens is incorporated for each COB, The holder and the light distribution control lens can be prevented from interfering with each other, and the light distribution control lens can be installed closer to the LED element, so that a wider-angle illumination can be realized. There is an advantage that it can be arranged so as to face the rectangular transparent plate of the opening for illumination more closely.

    The COB holder fixing part can be detachably screwed into one female screw hole used as a mount base COB holder attachment part, and is attached to a through hole drilled in a COB holder corresponding part.

It can be placed close to a rectangular transparent plate for illumination in the lamp housing of the lighting fixture for tunnels, realizing a wider-angle illumination, and an independent light distribution control lens for each light source module. Since it can be installed in the lamp housing of the tunnel lighting lamp, the arrangement and number of light source modules can be freely set according to the conditions of the installation location. A wide variety of light intensity for entrance lighting, exit lighting, and special structure lighting (for merging / merging, emergency parking, sidewalks, etc.) Also a plurality of types of illumination lamp made, outstanding feature that makes it possible corresponding at a low cost is obtained.

    According to the tunnel illumination lamp of the present invention, in addition to the effects of the above-described COB holder and the light source module using the same, a lamp housing having a plurality of types and sizes is manufactured according to various specifications with different illumination light amounts. However, unlike the previous ones, which had to prepare multiple types of molds and it was difficult to reduce the production cost, the main part of the lamp housing was The length dimension of the housing frame that constitutes the lamp frame can be freely set, and the long edge side plates are joined and integrated to the both ends of the casing frame in the length dimension direction, respectively. The length of the body can be set individually and freely, and multiple types of lamp housings with different dimensions can be produced with a single mold, which can be produced extremely efficiently. For basic tunnel lighting, entrance lighting, and exit For special lighting and special structure A great feature is that many types of lighting fixtures with various amounts of light, such as for light (for merging / dividing parts, for emergency parking zones, for sidewalks, etc.), can be produced and provided much more economically. .

    Furthermore, the lamp housing frame is made of a high thermal conductivity material, and is made of extruded metal, more specifically, made of an extruded aluminum alloy. By preparing only one type of mold, it is possible to efficiently produce a plurality of types of lamp housing housing frames having different length dimensions, and at both ends in the length dimension direction of the housing frame, The long end side plate made of high thermal conductivity material, the common long end side plate made of high thermal conductivity material, the common long end side plate made of metal, and more specifically, the common long end side plate made of aluminum alloy die casting shall be combined and integrated. As a result, the production efficiency can be improved, the production cost can be greatly reduced, the heat dissipation can be greatly improved while the size and weight are reduced, and the lamp life can be further extended.

    A product obtained by connecting and integrating the long end side plates to the both ends of the casing frame in the length direction direction via an attachment mechanism can significantly improve production efficiency and maintenance efficiency after installation. A rectangular transparent plate is detachably mounted and sealed in a sealing frame provided with a waterproof packing in the lighting opening that is continuous in a rectangular frame shape on both side walls and long end side plates of the lamp housing. By doing so, it is possible to produce efficiently, and the effect of ensuring high translucency, waterproofness and durability can be achieved.

    A heat sink that divides the interior of the lamp housing into a deep layer near the bottom wall and a surface layer near the lighting opening is detachably mounted so as to be parallel to the bottom wall, and power is supplied to the deep layer. Modules, dimming modules, etc. are arranged, and light source modules are arranged in the surface layer area, so that the light source module or the dimming module etc. does not transmit the heat generated by the power source module or the dimming module to the lamp from the deep area. Heat can be efficiently radiated outside the housing, and the heat generated by the light source module can be efficiently radiated from the surface layer area to the outside of the lamp housing, greatly extending the durability of the tunnel lighting fixture. It is possible to achieve higher density of parts, further downsizing, and the entire light source module can be attached and detached from each heat sink, greatly improving assembly / disassembly workability and maintenance workability. It will be very effective in that it is possible.
