DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a first embodiment of the lighting equipment of the present invention. This lighting equipment is used by being installed laterally on a wall surface inside or outside the room. The instrument main body 1, the electric component 2, the globe 3, and the reflection plate 8 are provided.

The instrument body 1 is made of metal such as an aluminum plate, and has a flange portion 1b at the peripheral end of a mounting surface portion 1a formed in a rectangular and substantially flat plate shape toward the front side which is one side thereof. It is erected and formed in a substantially box shape that opens to the front side,
The mounting surface portion 1a is mounted so that the one end 1c side of the instrument main body 1 faces upward and substantially abuts on the wall surface 4. A rubber packing 5 is attached to the tip of the collar portion 1b, and a drain hole 1e is provided on the other end of the instrument body 1.

The globe 3 is made of a translucent material such as glass or acrylic resin and has an opening 3a on one side. The vicinity of the opening 3a is narrower than the bottom 3c to form a shoulder 3d. The opening peripheral end portion is housed inside the collar portion 1b of the instrument body 1 so that the packing 5 attached to the collar portion 1b abuts the shoulder portion 3d with a set screw (not shown). It is attached to 1.

The reflecting plate 8 is formed by forming a taper portion 8b by bending one end of a base portion 8c arranged substantially parallel to the mounting surface portion 1a of the instrument body 1 toward the front side and bending upward at an obtuse angle. The end portion 8a on one end side is inside the globe 3 with respect to the opening portion 3a of the globe 3, and is between the end portion 8a on one end side of the reflection plate 8 and the flange tip 1d on the other end side of the instrument body 1. Is longer than the distance between the front end 1d of the collar portion on the other end side of the instrument body 1 and the opening peripheral end portion 3b on the one end side of the globe 3 so as to project inside the globe 3. There is. That is, when the globe 3 rotates around the tip of the collar portion 1b on the other end side of the instrument body 1, the reflector plate 8 is more reflective than the locus drawn by the opening peripheral end portion 3b on one end side of the globe 3. The end portion 8a on the one end side of 8 is configured to project outward.

The electric parts 2 such as the terminal block 2a, the ballast 2b and the socket are mounted on the front side of the reflector 8 and on the instrument body 1 side rather than the end 8a on one end side. On the upper side of the electric component 2, the tapered portion 8b plays a role like a roof.

Because of the above-mentioned structure, in the lighting fixture of this embodiment, the globe 3 is the fixture body 1
Even if the end of the flange 1b on the other end of the globe 3 is rotated around the tip and then comes off, the end 8a on the one end side of the reflector 8 is located outside the locus drawn by the opening peripheral end 3b on the one end side of the globe 3. Exists, the end portion 8a on one end side of the reflection plate 8 hits the inner wall near the opening peripheral end portion 3b on one end side of the globe 3, and the globe 3
It is possible to prevent the rotation of the glove 3 and prevent the glove 3 from being accidentally dropped. In addition, the tapered portion 8b of the reflection plate 8 reflects light downward in front of the luminaire 1 to ensure illuminance below the luminaire, and further, water entering from one end side of the luminaire main body 1 Or, the water droplets that have condensed inside the instrument body 1 do not flow down along the tapered portion 8b of the reflection plate 8 and do not flow down to the electric component 2, but flow out to the outside from the water drain hole 1e to lower the insulation of the electric component 2 or the lamp. It can prevent cracks. In particular, the instrument main body 1 is made of metal, and one end 1c side thereof is not directly exposed to the direct light from the lamp 7 and is likely to cause dew condensation, but water droplets caused by dew condensation at this portion do not reach the electric component 2.

FIG. 2 shows a second embodiment of the luminaire of the present invention. The difference from the first embodiment is the reflector 8 and the other parts are the same as the first embodiment. It is similarly configured.
