Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a lighting fixture, and more particularly to a lighting fixture having a reflector which has a predetermined shape under its own weight.

[Prior Art] Conventionally, for example, as shown in FIG. 9, in a lighting device 20 using a straight tube type fluorescent lamp, a reflector 21 made of a metal plate and curved to a predetermined curve is attached. . 1 reflector
There are cases where there are different types, or there are cases where a plurality of types are prepared and it is possible to select from among them by combining with the lighting fixture body.

[Problems to be solved by the invention] However, the curved reflector is bulky,
It was inconvenient and uneconomical in transportation and storage.

Also, after purchasing and installing lighting fixtures such as these,
If the light distribution is unsatisfactory, or if you want to change from wide-light to narrow-light or vice versa due to changes in the purpose of the room, etc., you can not change it and purchase a new lighting fixture that matches it I had to do it again.

It is an object of the present invention to provide a lighting fixture which does not have these drawbacks, is not bulky, and has a reflector which is convenient for packaging, transportation, storage and the like.

[Means for Solving the Problems] In order to achieve this object, the present invention provides a lighting fixture main body and a lighting fixture having a reflector attached to the lighting fixture main body, wherein one or more reflectors are provided on one side or both sides. It consists of a plate-shaped body with a book groove, and when the reflector is attached to the body of the luminaire and the luminaire is installed, the reflector bends by its own weight according to the angle of the groove to form a predetermined shape. It is configured.

[Operation] The reflector is plate-shaped before being attached to the main body of the luminaire,
When packaged and transported in that state and attached to the main body of the luminaire, the shape of the groove is formed by bending at its groove portion by its own weight according to the angle of the groove that is designed and determined in advance.

[Embodiment] In FIG. 1, a straight tube type fluorescent lamp 2 and a reflector 3 are attached to a luminaire main body 1. The reflector 3 is a plate-like body (FIG. 2), and a plurality of grooves 4 are formed on both the front and back sides in the longitudinal direction thereof.

The reflector 3 is made of a flexible material such as soft vinyl chloride, has a thickness of, for example, 2 to 3 mm, and has a mirror surface treatment such as plating, vapor deposition, or sticking on both front and back surfaces. A plurality of grooves 4 are provided on each of the front and back surfaces (first to third).
FIG. 4), the inclination angle of the groove 4 is different between the front and the back, and for example, the angle B of the groove on the front surface is larger than the angle A of the groove on the front surface (FIG. 4). As will be described later, this angle and the spacing between the grooves are designed in advance so that a desired light distribution can be obtained when the reflector is attached to the main body of the lighting fixture and the lighting fixture is installed, and its surface has a predetermined length. The surface state is such that an angle can be obtained.

The reflector 3 is packaged and transported in a plate-like state, and when the central portion 5 of the reflector 4 is attached to the luminaire main body 5 with a decorative screw or the like at the installation site, the reflector bends downward due to its own weight in the groove portion ( (FIGS. 1 and 5), the bending angle is determined by the angles A and B of the groove 4. When the front side, that is, the angle A side is attached to the lower side, a light distribution curve 6 as shown in FIG. 6 is obtained, resulting in narrow illumination. Also, when the angle B side is attached downward,
It becomes a light distribution curve 7 as shown in the figure, which provides wide illumination.

Incidentally, one surface of the reflector 3 may be mirror-finished and the other surface may be painted white, and the angles A and B of the groove 4 may be the same.

As shown in FIG. 8, the reflector 3 is composed of a plurality of layers in which a flexible film 8 such as a polyester film is arranged at the center and acrylic resin plates 9 whose outer surfaces are mirror-finished are attached to both surfaces thereof. You may

When it is desired to change the light distribution after the lighting fixture is once installed by changing the pattern of the room, etc., the reflector 3 may be removed once, and the reflector 3 may be attached again with the other surface facing down.

In the embodiment, the grooves 4 are provided on both the front and back sides so that both sides of the reflector can be used, but if it is not necessary to use both sides, the grooves may be provided on only one side.

[Advantage of Invention] In the lighting equipment of the present invention, the reflector is provided on one side or both sides.
Or a plate-shaped body having a plurality of grooves, and when the reflector is attached to the main body of the luminaire and the luminaire is installed, the reflector bends by its own weight at the position of the groove according to the angle of the groove to form a predetermined shape. As a result, the reflector is economical because it is not bulky during packaging and transportation, and a large amount can be handled at a time.

Further, even if no special device or mechanism is provided, the reflector is bent by its own weight so as to be bent into a shape such that a predesigned light distribution curve can be obtained.

Furthermore, by providing grooves on both the front and back sides, the front and back sides can be exchanged as required, and different light distribution curves and reflection conditions can be obtained, which is an advantage.
