[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to lighting equipment such as foot lights.

[0002]

2. Description of the Related Art FIGS. 3 and 4 show a conventional example. That is, this lighting fixture has an opening 50 on the side surface, and a fixture main body 53 provided with a lamp socket 52 for mounting a lamp 51 therein, and an opening 50 of the fixture main body 53 which is attached so as to close the opening 50. A frame 58 having a light-transmitting portion 57 at a position deviated to one edge portion and a non-light-transmitting portion 62 as a remaining portion, and a peripheral groove interposed between the frame 58 and the peripheral portion of the opening 50 to form a peripheral groove A ring-shaped packing 59 formed with 63;
9 and a light-transmitting panel 60 whose peripheral edge is fitted into the peripheral groove 63. 56 is a reflection plate, 61 is a frame 58 and
It is a tightening screw to tighten.

This luminaire is a footlight which is buried in a wall 64 and illuminates a foot.
7 is provided to cut upward glare.

[0004]

However, this lighting fixture has a drawback that the moisture of the mortar or concrete on the wall 64 enters the fixture from the power supply hole or the like, and dew forms on the inner surface of the translucent panel 60. . Although this lighting fixture is used as a footlight for illuminating the foot, when the fixture is used upside down to form an upper light, a foreign substance may enter the gap between the translucent panel 60 and the frame 58 from the translucent part 57. If water accumulates easily, water may be impaired, or the light-transmitting panel 60 may be damaged by freezing.

[0005] Therefore, an object of the present invention is to provide a lighting fixture which can prevent dew condensation and has no trouble even if the mounting direction is changed.

[0006]

The lighting fixture of the present invention is:
An appliance body having an opening on the side surface and having a lamp socket for mounting a lamp therein, and a light-transmitting portion attached to the appliance body so as to close the opening and displaced to one edge of the opening. A frame having a non-light-transmitting portion as the remaining portion, a ring-shaped packing interposed between the frame and the peripheral edge of the opening, and a peripheral groove formed in the inner periphery, and a peripheral portion in the peripheral groove of the packing. A light-transmitting panel fitted with the light-transmitting portion, and a partition piece for partitioning the non-light-transmitting portion and the light-transmitting portion of the frame to seal a gap between the non-light-transmitting portion and the light-transmitting panel. It is characterized by being formed integrally.

[0007]

According to the structure of the present invention, the lamp light is radiated to the outside from the translucent portion of the frame by turning on the lamp in the appliance body. In this case, since a non-light-transmitting part and a light-transmitting part of the frame are formed integrally with the packing to form a partition piece that seals a gap between the non-light-transmitting part and the light-transmitting panel, the light-transmitting part faces upward. Even if a lighting fixture is installed, water and foreign matter do not accumulate between the light-transmitting panel and the non-light-transmitting part, so that the waterproof property is not impaired and the light-transmitting panel is not damaged. No problem. Even in a state where the light-transmitting panel is not turned on, the sealed portion of the gap between the light-transmitting panel and the non-light-transmitting portion serves as a heat-retaining layer, which can prevent the temperature of the light-transmitting panel from lowering, so that dew condensation hardly occurs. During lighting, the temperature inside the lighting equipment rises and the air expands, but the air in the closed gap between the non-light-transmitting part and the light-transmitting panel expands. Since it is strongly pressed against the edge, the waterproofness can be improved. Further, since the middle portion of the light-transmitting panel is supported by the partition piece, the light-transmitting panel is reinforced. When the frame and the partition piece are bonded, the strength of the light-transmitting panel can be further improved.

[0008]

An embodiment of the present invention will be described with reference to FIGS. That is, this lighting fixture includes a fixture main body 1,
It has a frame 3, a packing 15, and a translucent panel 16.
The apparatus main body 1 has an opening 4 on a side surface and a lamp socket 6 for mounting a lamp 5 therein. The apparatus main body 1 has a box shape as an example, and the lamp socket 6 is attached to a side plate. In the embodiment, a recess 8 for embedding is formed on the floor side of the wall 7, the instrument body 1 is embedded in the recess 8, and the flange 9 at the edge of the opening 4 is locked to the wall surface. Further, a lead wire wired inside the wall 7 is drawn out from the inside of the concave portion 8 and connected to the lamp socket 6. Further, the reflecting plate 2 is disposed on the back side of the lamp 5 so as to reflect light toward a light transmitting portion 14 described later. Reference numeral 17 denotes a mounting portion having a female screw.

The frame 3 is attached to the instrument body 1 so as to close the opening 4 of the instrument body 1, has a light transmitting portion 14 at a position deviated to one edge of the opening 4, and has the remaining non-light transmitting portion 23. And In the embodiment, a hole 19 is provided corresponding to the mounting portion 17, and the frame 3 is mounted on the flange 9 of the instrument main body 1 by being tightened to the mounting portion 17 through the hole 19 by a tightening screw 18.
The packing 15 is interposed between the frame 3 and the peripheral edge of the opening 4 to form a ring shape having a peripheral groove 20 formed on the inner periphery. The packing 15 partitions the non-light-transmitting portion 23 and the light-transmitting portion 14 of the frame 3 to form a non-light-transmitting portion. The partition 22 for sealing the gap A between the light part 23 and the light transmitting panel 16 is formed integrally with the packing 15. In the embodiment, a hole 21 through which a tightening screw 18 passes is formed corresponding to the mounting portion 17, and is attached to the flange 9 of the instrument body 1 together with the frame 3 by the tightening screw 18, and a packing is provided between the frame 3 and the collar 9. 15 is more closely attached.

The light-transmitting panel 16 is formed on the peripheral groove 2 of the packing 15.
The light-transmitting panel 16 is held by the packing 15 by fitting the peripheral portion to the outer periphery. According to this embodiment, the lamp light is radiated from the translucent portion 14 of the frame 3 to the outside by turning on the lamp 5 in the appliance body 1. In this case, the packing piece 1 is used to partition the non-light-transmitting portion 23 and the light-transmitting portion 14 of the frame 3 to seal the gap A between the non-light-transmitting portion 23 and the light-transmitting panel 16.
5, the water and foreign matters do not accumulate between the light-transmitting panel 16 and the non-light-transmitting part 23, so that the waterproof property is impaired even if the lighting fixture is mounted so that the light-transmitting part 14 faces upward. Without damaging the translucent panel 16
Therefore, there is no problem even if the mounting direction is changed.

Further, even when the light is not turned on, the sealed portion of the gap A between the light-transmitting panel 16 and the non-light-transmitting portion 23 serves as a heat insulating layer, and the temperature of the light-transmitting panel 16 can be prevented from lowering, so that dew condensation hardly occurs. During lighting, the temperature inside the lighting equipment rises,
The air also expands. In this case, the air in the instrument body 1 is exhausted from a power supply hole (not shown) or the like, but the air in the closed gap between the non-light-transmitting portion 23 and the light-transmitting panel 16 expands, so that the air in the light-transmitting panel 16 is expanded. The packing 15 is connected to the opening 4 of the instrument body 1.
The waterproofness can be improved because it is strongly pressed against the edge of the.

Further, the light-transmitting panel 16 is formed by the partition piece 22.
Since it supports the middle part, the light-transmitting panel 16 is reinforced,
When the frame 3 and the partition piece 22 are bonded, the strength of the translucent panel 16 can be further improved. Frame 3
May be square or circular.

[0013]

According to the lighting device of the present invention, a partition piece that separates the non-light-transmitting portion of the frame from the light-transmitting portion and seals the gap between the non-light-transmitting portion and the light-transmitting panel is formed integrally with the packing. Therefore, even if the lighting fixture is mounted so that the light-transmitting part faces upward, water or foreign matter does not accumulate between the light-transmitting panel and the non-light-transmitting part. Therefore, there is no problem even if the mounting direction is changed. Even in a state where the light-transmitting panel is not turned on, the sealed portion of the gap between the light-transmitting panel and the non-light-transmitting portion serves as a heat-retaining layer, which can prevent the temperature of the light-transmitting panel from lowering, so that dew condensation hardly occurs. During lighting, the temperature inside the lighting equipment rises and the air expands,
Since the air in the sealed gap between the non-light-transmitting portion and the light-transmitting panel expands, the packing is strongly pressed by the light-transmitting panel against the edge of the opening of the appliance body, so that the waterproofness can be improved. Further, since the intermediate portion of the light-transmitting panel is supported by the partition piece, the light-transmitting panel is reinforced. When the frame and the partition piece are bonded, the strength of the light-transmitting panel can be further improved.
