The inspection lid 13, which is the upper surface portion, can be easily opened and closed from above the facing arch 1.
At this time, the inspection lid 13 is tilted forward, which is the opposite side to the position where the worker is, so that the inspection lid 13 does not interfere with the maintenance / inspection work and the workability is improved.

With the inspection lid 13 open, the tightening bolts 26a on the mounting pieces 26 of the light-emitting body 20 are loosened so that the units 20A, 20B,
20C can be easily taken out through the opening 12. In the present embodiment, since the light emitting body 20 is composed of the LED 23, the light emitting body 20 itself can be designed to be thinner than the most commonly used conventional reflector type, and the light emitting body 20 can be put in and taken out. The area of the opening 12 can be made as narrow as possible.

As shown in FIG. 3, in the opening 12 of the present embodiment, two units 20A / 20B / 20 are provided.
It is possible to take out and put in at the same time in a state where Cs are arranged side by side. However, the opening area of the opening 12 may be set so that at least one largest unit can be inserted,
If it is made smaller, the rainproof property of the entire housing body 11 can be improved.

Further, as shown in FIGS. 7 and 8, since the back side of the substrate 22 constituting each unit 20A, 20B, 20C is covered with the cover member 25 having heat conductivity,
The heat generated from the substrate 22 can be efficiently released. Further, since the cover member 25 is provided with the round hole 25a, the heat radiation effect can be further improved. Moreover, by covering the back side of the substrate 22, it is possible to prevent the operator from directly touching the electronic component 24 and the like, and it is possible to eliminate the risk of electric shock and the like.

As shown in FIG. 1, the housing main body 11 is provided with a receiving rail 32 to which the light emitter 20 is detachably guided and which can be positioned at a predetermined position. It becomes possible to lead to an accurate position in the main body 11. Therefore, the light emitting body 20 can be quickly put in and taken out for maintenance and inspection.

As shown in FIGS. 1 and 9, the leg portion 27 of each unit 20A, 20B, 20C has a receiving rail 32.
It can be slid in the longitudinal direction while being fitted inside. A projection 33 for holding each unit 20A, 20B, 20C in a fixed position is projected on the bottom surface of the receiving rail 32, and the positioning hole 28 in the leg 27 is engaged with the projection 33. Therefore, it can be easily positioned.

After the maintenance / inspection of the light emitter 20,
When actually installed in the housing body 11,
As shown in FIG. 1, if the light-shielding screen 41 is inserted between the light emitting body 20 and the cover body 30, it is possible to carry out a lighting test of the light emitting body 20 without irradiating the light substantially forward. . Since the light shielding screen 41 is detachably guided in the housing body 11 and the locking rail 42 which can be positioned at a predetermined position is provided, the light shielding screen 4 is provided.
The 1 can be quickly installed at the correct position in the housing body 11.

A magnet 43 is provided at the upper end of the front portion 16 of the housing body 11 so that the upper edge of the light-shielding screen 41 positioned by the locking rail 42 comes into close contact therewith, so that light leakage can be reliably prevented. When the lighting test is performed after the maintenance and inspection are completed, it cannot be visually recognized by the vehicle running on the road, and it is possible to prevent the driver of the vehicle from erroneously recognizing it. The magnet 43 may be provided also at a key portion of the inner wall of the housing body 11 where the side edge of the locking rail 42 is in contact.

Further, the housing body 11 may be made of an iron material or the like that adheres to the magnet, and the magnet 43 may be provided on the light shielding screen 41 side. With such a configuration, the magnet 43 need only be provided at one location on the light-shielding screen 41 side. The light-shielding screen 41 is not mounted in the housing body 11 during normal use of the signal lamp 10, but is mounted and used in the housing body 11 only during maintenance and inspection.

The signal lamp 10 according to the present invention is not limited to the above-described embodiment, and, for example, in the above-mentioned embodiment, the inspection lid 13 which is the upper surface of the housing body 11 is moved forward. Although it is configured to fall, it may be configured to open and close so as to fall to the side.

[0056]

According to the signal lamp according to the present invention, the housing body has the rear surface side attached to the front surface of the arch, and the upper surface of the housing body can be opened and closed with respect to the housing body. It is possible to easily open and close the upper surface portion of the housing from above the arch where the rear surface side of the housing faces, without wrapping around the front side of the signal lamp as in the conventional case, and to maintain and inspect the inside. Therefore, it is not necessary to regulate traffic on the road at the time of maintenance / inspection of the signal light device, and it is not necessary to provide a dedicated work road on the arch, and it is possible to prevent traffic congestion and cost increase. . Moreover, since the luminous body is divided into a plurality of units and the opening area opened and closed in the upper part of the housing body is set to a size that allows at least one of the largest units to be inserted, the opening area of the housing body is made as small as possible. Therefore, the rainproof property of the entire housing body can be improved.

Further, according to the mounting structure of the signal lamp according to the present invention, when the maintenance / inspection work of the signal lamp is performed from above the arch, the operator is not only on the arch but also on the scaffolding base of the mounting bracket. You can stand and improve the workability of maintenance and inspection.
