DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reflector device in which a reflector main body is made lighter and a desired light distribution curved surface is formed by a reinforcing plate. More specifically, the reflector device reflects light and is thin and flexible. The present invention relates to a reflecting mirror device using a flat anti-reflection member as a reflecting mirror having a light distribution curved surface.

2. Description of the Related Art Conventionally, a reflector is made of a base material of a reflector by a casting mold or an extruder using a mold or a mold, or reflects a soft metal material (for example, aluminum or brass) among relatively metal materials. There is a mirror body which is machined as a mirror block. Each reflecting mirror body produces a concave mirror having a shape conforming to desired conditions. In addition, in order to improve the glitter of the reflecting surface of the manufactured reflector, nickel plating is applied as a base on the rough side of the reflector surface, and glossy chrome plating is applied on this nickel plating layer. I have.

[0003]

As described above, in the former method of manufacturing by molding, extruding or cutting, there is a limit in terms of reducing the thickness of the reflector main body. Even if the length of the main body is short, there is a disadvantage that the material cannot be reduced because the material is metal and the thickness cannot be reduced. In order to prevent scattering of the reflected light, if the reflecting surface portion of the reflecting mirror body is made longer, the light collecting property is improved, but on the other hand, there is a disadvantage that the weight of the reflecting mirror body is large and it is difficult to carry. Further, there is a drawback that if the reflecting surface portion of the reflecting mirror is lengthened, uniform plating cannot be applied to the depth of the concave portion of the reflecting surface.

[0004] In addition, since the reflecting mirror is parabolic, there is a major drawback in that processing defects occur in the curved surface portion in the plating process. Casting and cutting use a large amount of material, which increases the cost. Further, if the length of the reflecting mirror body is long, a desired light distribution cannot be obtained. In addition, the curved reflecting mirror has a disadvantage that it takes up a lot of storage space.
An object of the present invention is to eliminate such a drawback by reducing the weight of the main body portion, which becomes a curved reflecting mirror in cross section, by a flat plate reflecting member, and distributing light to the flat plate reflecting member by a light distribution curved surface of a reinforcing plate. It is to form a curved surface and obtain a desired light distribution and robustness.
