Abstract

PROBLEM TO BE SOLVED: To provide a low-cost luminaire wherein a prism plate is used as a reflector and boring is not necessary. SOLUTION: A long reflector 7 comprising a transparent or translucent prism plate, at least one side of which is formed into an uneven surface and whose upper end part is bent, is held by and fixed to both longitudinal side parts of a long-shaped reflector attaching member 5, which is attached to an under surface of a long luminaire body 2 having sockets disposed on opposite ends thereof and whose under surface is adapted to be a reflection surface, such that an upper end part 7a of the reflector 7 is sandwiched between a pressing member 9 which bends along the shape of the upper end part of this reflector 7 and an end part of the reflector-attaching member 5 and that the pressing member 9 is fixed to the reflector-attaching member 5 by a fastener 8. As a result of this, the reflector 7 is hold by and fixed to the reflector- attaching member 5 so that boring holes need not be provided in the reflector 7.

のような穴明け加工には余分なコストがかかる。The use of a prism plate as a reflector has many advantages as described above, but also has disadvantages. That is, the prism plate itself is quite expensive. Further, such a prism plate is easily broken. For example, in order to fix the prism plate to the main body, it is necessary to perform a hole processing for providing a screw or a hole for the latch 21 in the prism plate. The possibility of damaging the prism plate is high. Further, when the prism plate is fastened to the main body with a screw or a latch using this hole, there is a disadvantage that the periphery of the hole of the prism plate is easily damaged. Moreover, such drilling involves extra costs.

In the figure, two sockets 3 are arranged at both ends of a long main body 2, and a straight fluorescent lamp 4 is mounted on each of them. On the lower surface of the main body 2, an elongated reflector attaching member 5 having substantially the same length as the main body 2 is attached to the main body 2 by a latch 6. The reflecting plate mounting member 5 is made of a metal plate, and its surface is painted white, for example, to form a reflecting surface. On both sides in the longitudinal direction of the reflector mounting member 5, reflectors 7 made of a prism plate are mounted. The reflecting plate 7 is made of a transparent or translucent translucent material, such as a synthetic resin plate such as an acrylic resin or a glass, provided with innumerable, for example, triangular irregularities on both surfaces or one surface.

The holding member 9 extends in the longitudinal direction of the main body 2 of the lighting fixture and the reflector attaching member 5, and is bent along the bend of the upper end 7a of the reflector 7 in the cross section. A hole (a hole of the holding member 9 is threaded) is formed in the reflecting plate mounting member 5 and the holding member 9, and the reflecting plate 7 is fixed by tightening a screw 8 as a stopper here. . No holes are formed in the reflection plate 7. The reflector 7 is held at three points: the bent end 9a of the holding member 9, the flat portion 9b, and the end 5a of the reflector attaching member, and is securely attached to the reflector attaching member 5.

Nothing. Further, in the lighting fixture of the present invention, the prism plate does not exist between the fluorescent lamps, but since the reflector mounting member has a reflecting surface, it is possible to prevent a decrease in luminance between the fluorescent lamps and to prevent the fluorescent lamp from being lowered. Since the light is directly reflected in the direction of the prism plate, the reflection efficiency is better than the case where the prism plate exists between the fluorescent lamps. Also, the cost can be reduced as the area of the prism plate is small. Further, since the prism plate is not perforated, the cost for perforation can be reduced without damaging the prism plate.
