(Points of interest)
Conventional large-sized lighting fixtures installed on roads and tunnels use fluorescent tubes such as high-pressure sodium lamps and fluorescent lamps. When the fluorescent tubes reach the end of their service life, temporarily lane them. The lamp housing has a hinge for opening and closing the transparent cover and a latch that can be locked in the closed state in order to replace only the fluorescent tube using an aerial work vehicle. However, in recent years, the installation of LED lamps that have a longer life than conventional fluorescent tubes has increased, and such LED lamps can be replaced at the installation site even when the LED module reaches the end of its life. Instead, the lamp housing is replaced and installed, the transparent cover of the lamp housing that is brought back to the factory is opened, the LED module is replaced, and maintenance is performed.

    Along with such changes in maintenance work, the LED lighting fixture housing does not require a hinge or latch for opening and closing the transparent cover, and can be opened and closed efficiently in factory work. It is necessary to develop a new housing part for lamps that has a closing mechanism that can keep the annular packing for a long time by closing it so that it is compressed properly without over-compressing the annular packing. became.

(Conventional technology)
Reflecting this situation, proposals that can be used to overcome this situation are not unheard of.
For example, as represented by those proposed in the following Patent Documents 1 (1) to 1 (3), the transparent cover is sealed against the female screw portion or screw hole provided in the main body of the lamp housing. The compressed state of the annular packing that is screwed with screws and arranged along the periphery of the housing body and interposed between the periphery of the transparent cover is managed by the tightening torque of each sealing screw If a notch is provided along the circumference of the annular packing mounting bracket as shown in Patent Document 1 (4) and the tightening force of the sealing screw is too strong, Some of them are elastically deformed and can prevent the annular packing from being excessively crushed.

However, the lamp housings as shown in the former Patent Documents 1 (1) to 1 (3) are all accurate in tightening torque of all the sealing screws when the transparent cover is attached to the housing body. Otherwise, the annular packing may be under-compressed, excessively compressed, or unevenly compressed, which may lead to ingress of water, dust, etc., or early deterioration of the annular packing. In the case of the one represented by Document 1 (4), a mounting bracket provided with an annular cutout corresponding to the annular packing must be provided over the entire circumference of the main body opening of the lamp housing. There is a disadvantage that there is a risk of increasing the manufacturing cost and the weight, and the manufacturing cost.

(Awareness of problems)
As described above, various types of lamp housings that have been proposed so far allow the transparent cover to be detachably attached by a plurality of sealing screws. However, if the tightening torque is not accurately managed, There is a risk of premature deterioration, intrusion of water, dust, etc., and a lamp housing that is equipped with a mounting bracket with a fragile part so as not to require tightening torque management is used for the mounting bracket. It has the disadvantages of increasing the size and weight, making it difficult to produce economically, avoiding the increase in size of the mounting bracket, making it possible to reduce the weight, making it inexpensive and fixing the transparent cover We came up with the idea that a new lamp housing part should be developed that eliminates the need to manage the tightening torque of the sealing screw and increase the efficiency of maintenance work in the factory.

As a result, the seat packing can further improve the waterproofness and dustproofness and achieve an extremely high reliability.

In implementing the present invention having the above-described configuration, the best or desirable mode will be described.
The receiving bracket has a function of enabling the closure of the vicinity of the opening edge of the container-type main body and the hook attached to the vicinity of the outer periphery of the transparent cover combined with the lid of the container-type main body in a lid shape. From the mounting seat that can be fixed to any one of a plurality of locations on the peripheral wall that is balanced around the periphery of the opening edge of the housing container type main body, the mounting posture extends beyond the opening edge of the container type main body. The connecting arm having the sealing screw hole, the anti-hand stopper restricting portion and / or the stopper convex piece should be extended toward the outer wall of the LED lamp housing container body. From the mounting seat that has two or more studs that can be installed in each mounting hole, so that it can be fixed to any one of the parts, and beyond the opening edge of the container-type main body toward the outer side, two or more Female screw hole, anti-hand stopper regulation It is desirable to extend the connecting arm having the stopper convex piece, and as shown in the examples described later, the connecting arm portion from the mounting seat is made of a pressed stainless steel plate having excellent corrosion resistance. It is possible to implant stainless steel bolts at appropriate positions on the mounting seat and to integrate them by welding, or to connect one or a plurality of continuous bolts from the mounting seat or the vicinity of the mounting bolt to the vicinity of the female screw hole. The reinforcing ridges can be integrally formed, and the reinforcing ridges can be replaced with those in which the reinforcing ribs are integrated by welding or the like.

    Each sealing screw hole on the bracket connection arm bears the function of allowing the tip of the sealing screw attached from the mounting hole on the hanging bracket connection arm to be clamped and fixedly connected. Should be concentrically placed in each mounting hole of the hook connecting arm in a combined state, so that each sealing screw should be easily combined, and a separate nut can be built in by providing a fool hole It is possible to provide a fool hole and integrate the nut by welding or fitting, or to engrave a female screw in the through hole itself. The hole can be a female threaded hole, and the anti-hand stopper restricting part of the bracket can restrict the proximity of the hook stopper convex piece to the optimal compression position of the annular packing when tightening the sealing screw To handle the hanging bracket In the case of having a stopper restricting portion, it is possible to obtain a stopper restricting action, so that it is not always necessary to provide a hand stopper restricting portion on the bracket, but in order to obtain the stopper restricting action more reliably, It is preferable that an anti-hand stopper restricting portion and a stopper convex piece are provided on the metal fitting.

    The stopper convex piece of the receiving bracket is in contact with the hanging bracket-to-hand stopper restricting portion when tightening the sealing screw, and has a function that can be regulated to the optimum compression position of the annular packing. In the case of having a piece, it is possible to obtain a stopper regulating action, so that it is not always necessary to provide a stopper convex piece on the metal fitting. However, in order to obtain the stopper regulating action more reliably, the stopper convex piece is provided on the metal fitting. It is preferable that an anti-hand stopper restricting portion is provided.

    The hanging bracket bears the function of making it possible to fix the vicinity of the outer peripheral edge of the transparent cover and the receiving bracket attached to the vicinity of the opening edge of the container-type main body in which the transparent cover is combined in a lid shape, Mounting position from the mounting seat that can be fixed to any one of the outer peripheral wall near the opening edge corresponding to each mounting position when the casing lid type transparent cover is combined with the opening edge of the container body. The connecting arm with bolt mounting hole, stopper convex piece and / or anti-hand stopper restricting part must be extended toward the outer side beyond the bowl-shaped outer periphery at It is preferable that two or more studs that can be mounted in the mounting holes of the respective hanging bracket mounting portions of the lid-type transparent cover are erected, and as shown in the embodiments described later, the portion of the connecting arm from the mounting seat To corrosion resistance It can be made by pressing a stainless steel plate into a suitable place for the mounting seat, and by integrating a stainless steel bolt into the mounting seat at an appropriate location, and by welding. One or a plurality of reinforcing ridges that are continuous with each other can be integrally molded, and the reinforcing ridges can be replaced with one in which reinforcing ribs are integrated by welding or the like.

    The bolt mounting hole of the hanging bracket connecting arm shares the function of enabling the installation of a sealing screw that is screwed into the female screw hole of the receiving bracket connecting arm. With the lid-type transparent cover combined with the container-type main body, It should be concentrically placed in the sealing screw hole or female screw hole of the receiving arm connecting arm, so that the closing screw should be easily attachable. Since it has a function to allow the proximity position of the stopper convex piece to be regulated to the optimum compression position of the annular packing, and the receiving metal fitting has a hand stopper regulating portion, the stopper regulating action can be obtained thereby. Although it is not necessary to provide the anti-hand stopper restricting portion on the hanging bracket, it is assumed that the stopper fitting piece and the anti-hand stopper restricting portion are provided on the hanging bracket in order to obtain the stopper restricting action more reliably. It is good.

    The stopper convex piece of the hanging bracket abuts against the receiving bracket-to-hand stopper restricting portion when tightening the sealing screw, and has a function that enables the optimal compression position of the annular packing to be regulated. In the case of having a convex piece, it is not always necessary to provide the stopper convex piece because the stopper regulating action can be obtained thereby, but in order to obtain the stopper regulating action more reliably, the stopper convex piece and the pair are attached to the hanging bracket. A hand stopper restricting part should be provided.

From the hanging bolt mounting hole, It is possible to connect the two with sufficient strength by reaching the female screw hole, and the screw part can pass through the hanging bolt mounting hole, and the nut or female screw facing the receiving metal sealing screw hole It must be set to a nominal diameter that can be screwed into the hole, and should have a head with a diameter that cannot pass through the bolt mounting hole, and should be made of stainless steel with excellent corrosion resistance. It is desirable to have a special head for preventing mischief, such as a star-shaped (hexlobe) groove, which cannot be easily removed with a normal tool such as a flat-blade screwdriver or a flat-blade screwdriver.

    Each length dimension from the connecting arm of each of the receiving metal fittings of the above-described receiving metal fittings of the receiving metal fittings to the contact position of each of the stopper protruding pieces and the protruding piece of the hanging metal fittings, and the protruding piece of the hanging metal fittings is determined. The container-type main body packing mounting seat and the lid-type transparent cover when the hand stopper restricting part and the hanging stopper stopper projecting piece contact and / or The annular packing interposed between the flange-shaped outer peripheral edges should be set so as to have an optimal and constant dimensional relationship.

    The container-type main body of the LED lamp housing allows the LED module to be housed in an appropriate place inside, and secures an opening that can illuminate the illumination light from the LED module and can be fitted with a lid-type transparent cover. It has a function to fix the bracket in place, it must be a container shape that can store the LED module, and it must have an annular packing along the opening edge, and it can store and install the LED module. A ring-shaped packing is mounted on a packing mounting seat provided along the edge of the opening of the light guide, and is arranged in a balanced manner around the opening edge of the peripheral side wall in the vicinity of the packing mounting seat. It should be the one where the bracket mounting part is set.

It is preferable that the annular packing is a silicone rubber waterproof sponge packing, and a silicone rubber sheet packing is sandwiched between the mounting bracket mounting seat to ensure waterproof and dustproof properties.

    The packing seat on the opening edge of the container-type main body allows the annular packing to be tightly attached along the opening edge of the container-type main body, and allows the annular packing to be compressed between the outer periphery of the lid-shaped transparent cover bowl. In addition to sharing the function of allowing the container-type main body to be sealed, the container-type main body can be of a groove type that opens in the same direction as the opening edge of the main body. It can be of an annular step shape in which the inside of the edge is lowered by one step.

The lid-type transparent cover of the LED lamp housing is capable of closing the container-type main body opening in a sealed manner, sharing the function of allowing the light emitted from the LED module housed in the container-type main body to be transmitted to the outside. The peripheral edge must correspond to the opening edge of the container type main body and be in a shape that can contact and seal the annular packing, and the bowl-shaped outer peripheral edge corresponds to the opening edge of the container type main body and can contact and seal the annular packing When the shape is combined with the opening edge of the container-type main body, it should be the one where the hanging bracket mounting portion is set at each location near the opening edge corresponding to each receiving bracket mounting portion, ensuring high light transmittance, It can be made waterproof and dustproof, made of a material that is not easily deteriorated by transmitted light or heat, and can be made of a transparent synthetic resin that excels in light transmission. With two or more mounting holes And setting, sandwiched sheet packing between the hanging bracket mounting seat, can be provided with securing waterproof and dust resistance, a cover-type transparent cover becomes convenient when the glass cover.
