DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary device for a reflector main body mounted on a front portion of the reflector main body.
The present invention relates to an auxiliary device of a main body of a reflecting mirror which is used as a reflecting mirror having a curved surface to be distributed, in which a thin flat reflecting member which reflects light and is bent is used as a reflecting mirror.

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 order to improve the brilliancy of the reflecting surface, the manufactured reflector body is plated with nickel on the rough surface side of the reflector body surface as a base, and glossy chrome plating is applied on this nickel plating layer. I have.

In order to efficiently irradiate the object with the reflected light from the reflecting mirror, a reflecting mirror provided with a reflecting mirror auxiliary member as a projector for preventing the reflected light from leaking sideways is disclosed in the front of the reflecting mirror body. There is a patent publication (JP-A-6-27312).
The applicant of the present invention is the same applicant as the present invention.
Further describing the prior application in detail, the reflector base body of the reflector body has a curved inner wall surface, and a light reflective layer provided on the curved inner wall side, It is constituted by a reflector auxiliary member which extends from the opening edge of the front part of the reflector main body and is provided with a light reflecting layer. The reflector auxiliary member is a thin plate surrounding the front of the reflector main body to prevent the reflected light from leaking sideways.

As described above, in the former method of manufacturing by casting or extruding or cutting, there is a limit in the condition that the thickness of the reflecting mirror body is reduced.
Even if the length of the reflecting mirror body to be manufactured is short, there is a disadvantage that the material is metal and the wall thickness is limited in the cutting of the mold, and the weight cannot be reduced. Further, since the reflected light leaks from the side of the reverberation main body, if the reflecting surface of the reflecting mirror main body is lengthened, the light collecting property is improved, but the weight of the reflecting mirror main body is large and there is a disadvantage that it is difficult to carry.

[0005] Prolonging the length of the reflecting surface of the reflecting mirror body has the disadvantage that the plating is not uniform on the inner part of the reflecting surface. Therefore, there is a drawback that many processing defects occur in the plating process. Further, there is a disadvantage that the cost is increased because a large amount of material is used. Moreover, in the latter invention, the reflector auxiliary member is extended at the front portion of the reflector main body in order to improve the light collection. However, there is no drawback that the glitter cannot be enhanced.

An object of the present invention is to provide a light distribution curved surface having a light distribution condition of a reinforcing plate, wherein the auxiliary device of the reflector main body uses a light-weight and flexible flat reflection member and the light distribution condition of the reinforcing plate. An object of the present invention is to form a light distribution curved surface on a flat reflecting member to obtain a desired light distribution and robustness.
