A cam lock fastener socket 30 is attached to both ends of the support plate 25 to which the lighting fixture 10 is attached, and the insertion hole 41 for the fall prevention metal fitting is formed.

The support plate 25 on which the illumination device 10 is mounted is attached to the eyeless 18. As shown in FIG. 3, a metal mold 19 is attached to the interior of the seamless frame 18 a constituting the seamless 18, and a rail 20 is attached to the metal mold 19, and a pulley 21 is attached to the rail 20. Through this, the pulling door 16 is suspended so that it can be opened and closed automatically or manually. Moreover, the hollow part 37 by which the upper end part of the glass of the fitting door 17 is inserted and fixed is provided in the lower end part of the said blind frame 18a, and the lighting fixture 10 of this invention is the attachment of the fitting door 17 In the case of the one-way door 16 using a portion that is not provided, it is attached downward to a substantially central portion of the closed door. In the support plate 25 to which the lighting fixture 10 is attached, in which the attachment member 36 protrudes inside the hollow portion 37, the locking portions 48 formed on both sides of the support plate 25 are press-fitted and locked.
Further, as shown in FIGS. 5 and 6, the support plate 25 may be fixed to the mounting member 36 with screws 38 inside the hollow portion 37.
Further, when the attachment member 36 does not protrude inside the hollow portion 37, as shown in FIG. 8, the upward U-shaped support plate 25 is fixed by protruding to the blind frame 18a with screws 47. Also good.

Below the support plate 25, there is provided a mounting and light distribution plate 28 as a light distribution device having a light distribution long hole 32 for determining the light distribution range of the floor surface by the lighting fixture 10. A cam lock fastener plug 31 that is detachably coupled to the plug insertion hole 44 of the cam lock fastener socket 30 is attached to both ends of the attachment / light distribution plate 28. Since the light distribution elongated holes 32 are formed in the mounting / light distribution plate 28, the light beam from the LED light source 22 has a predetermined light distribution angle θ1 depending on the shape of the light distribution elongated holes 32 in the exit / exit direction. Irradiated with.
This light distribution angle θ <b> 1 can be adjusted by the shape of the light distribution long holes 32. Moreover, you may adjust with the distance of the mounting and light distribution plate 28 and the LED light source 22. FIG. In FIG. 2, θ2 is a light distribution angle in the door opening direction, and the light distribution angle θ2 in the door opening direction may be an angle that sufficiently irradiates the floor surface 14 of the doorway. Is not set.

  In addition, ring portions 46 of the drop-off prevention metal fitting 40 are attached by washers 43 to both ends of the attachment / light distribution plate 28 so as to face the base of the cam lock fastener plug 31. The drop-off prevention metal fitting 40 is wire-like and extends obliquely upward, and has a bent locking portion 45 at the tip. In order to attach the mounting / light distribution plate 28 to the lower surface of the support plate 25 on which the lighting fixture 10 is mounted, as shown in FIGS. 5 and 6, the drop-off prevention metal fittings 40 at both ends of the mounting / light distribution plate 28 are supported by the support plate. 25, and the cam lock fastener plug 31 of the mounting and light distribution plate 28 is inserted into the plug insertion hole 44 of the cam lock fastener socket 30, the cam lock fastener socket 30 and the cam lock fastener plug 31 are coupled by an internal spring. As shown in FIG. 6, the drop-off prevention metal fitting 40 protrudes above the support plate 25.

  When the mounting / light distribution plate 28 is removed from the support plate 25, when the cam lock fastener plugs 31 at both ends are pushed in from below, the cam lock fastener socket 30 is disengaged by the spring. Then, the mounting and light distribution plate 28 is detached, but the bending locking portion 45 at the tip of the drop-off prevention metal fitting 40 is locked on the upper surface of the support plate 25 and does not fall. Even when the cam lock fastener plug 31 is removed from the cam lock fastener socket 30 for some reason, the mounting and light distribution plate 28 does not fall.

Since the light distribution elongated holes 32 are formed in the mounting / light distribution plate 28, the light beam from the LED light source 22 has a predetermined light distribution angle θ1 depending on the shape of the light distribution elongated holes 32 in the entrance / exit direction. Irradiated with.
This light distribution angle θ <b> 1 can be adjusted by the shape of the light distribution long holes 32. Moreover, you may adjust with the distance of the mounting and light distribution plate 28 and the LED light source 22. FIG. In FIG. 2, θ2 is a light distribution angle in the door opening direction, and the light distribution angle θ2 in the door opening direction may be an angle that sufficiently irradiates the floor surface 14 of the doorway. Is not set.

With the above configuration, as described above with reference to FIG. 1, the elevation angle of the LED light source 22 increases as the person 15 approaches B, C, D and the entrance 12, and the LED light source 22 must be looked up consciously. Since the light beam from the light beam does not directly enter the eyes of the human 15, the bright light beam of the LED cannot pass through the eyes and can pass safely until the human person comes close to the door.
The LED light source 22 of the luminaire 10 may be stationary lighting, blinking lighting, constant lighting, lighting synchronized with door opening / closing, or the like.

  In the above embodiment, as shown in FIG. 2, the lighting apparatus 10 for the one-way door 16 has been described. However, the present invention is not limited to this, and as shown in FIGS. Therefore, the two lighting fixtures 10 can be arranged in the longitudinal direction. In this case, the conduction hole 26 is formed for each lighting fixture 10. In addition, the mounting position of the lighting fixture 10 is an upper portion of the summing position of the two double doors 35.

In the said Example, as shown in FIG. 7, the long hole 32 for light distribution which determines the light distribution angle (theta) 1 in the exit / entry direction was formed in the attachment and light distribution plate 28 of the lowest end of the lighting fixture 10, and it was set as the light distribution apparatus. However, the conduction hole 26 of the inner support plate 25 can be shaped to determine the light distribution angle θ1. In this case, the light distribution elongated holes 32 of the mounting / light distribution plate 28 are formed large so as not to obstruct the light distribution angle θ1.
In addition, a lens can be used for the light distribution angle θ1 regardless of the light distribution long holes 32.

  In the said Example, although it was set as the example which attaches the lighting fixture 10 facing the sliding door type automatic doors, such as a building and a vehicle, a rotary type automatic door may be sufficient and a manual door may be sufficient instead of an automatic door. Further, it may be a doorway without a door, a hallway, or the like.

In the above embodiment, it is attached so as to be embedded in the invisible frame 18a, but it can also be directly attached to the ceiling 13 as shown in FIG.
In the above embodiment, the mounting / light distribution plate 28 and the support plate 25 are detachably coupled by the cam lock fastener socket 30 and the cam lock fastener plug 31. Therefore, a wire-like drop-off prevention fitting 40 is attached to the attachment / light distribution plate 28, and the upper end bent portion 45 of the drop-off prevention fitting 40 is passed through the drop-off prevention fitting insertion hole 41 of the support plate 25 to the upper portion of the support plate 25. Protruded. However, the present invention is not limited to this, and the attachment / light distribution plate 28 may be directly fixed to the lower side of the support plate 25 with screws.
