【考案の詳細な説明】
本考案は、自動車などに装備する車両用灯具、
特にその前面レンズの改良に関するものである。[Detailed description of the invention] This invention is a vehicle lamp installed in a car, etc.
In particular, it concerns improvements to its front lens.
車両用灯具は、一般に反射鏡を兼ねたハウジン

る。おな、５は電球である。 Even if the colored part 3 is provided partially on the front surface in this way, if the colored part 3 is located at a position opposite to the seam of the fisheye cut as shown in FIG. When the light enters, it passes through the gap between the colored parts 3 while being condensed, and then diffuses, so it has no effect on parallel incident light, and sufficient illumination power can be obtained. By the way, number 5 is a light bulb.
しかし、このような構造では、側方への照明光

ある。 However, in such a structure, side illumination light is blocked, resulting in reduced side visibility. Also,
Since the front surface of the lens is painted or hot stamped, there is a problem that the lens 2 becomes thicker.
本考案は側方視認性の改善及びレンズの薄肉化
が図れる車両用灯具を提供することを目的とす
る。 An object of the present invention is to provide a vehicle lamp that can improve lateral visibility and have a thinner lens.

ことを特徴とする車両用灯具である。 The present invention has a lamp housing that also serves as a reflector, a fisheye cut on the back side of the lens base material, and a substantially V-shaped groove on the front face at a position opposite to the seam of the fisheye cut. , comprising a reflective film formed on the side wall surface of the groove, a lens filled with an opaque paint in the groove and disposed on the front surface of the housing, and a light bulb mounted in the housing. This is a vehicle light.
以下、本考案を実施例に基づいて詳細に説明す
る。 Hereinafter, the present invention will be explained in detail based on examples.

となる。 FIG. 4 shows an embodiment of the present invention, in which the lens 10 has a fisheye cut 11 formed on the back surface of the base material, and a fisheye cut 11 facing the seam of the fisheye cut 11 on the front surface of the base material. A V-shaped groove is formed at the position, and a reflective film 12 is provided on the side wall surface of the groove by vapor deposition of aluminum or high-reflection silver coating, and an opaque paint 13 is filled in the groove. In this case, the sides of the groove are flat (straight in cross section)
becomes.
このようなレンズ構造とすると、平行入射光ａ

ン上要求される彩色領域も確保できる。 With such a lens structure, parallel incident light a
Most of the light travels in the direction of the optical axis of the lamp while being focused by the light focusing action of the fisheye lens, but some of it is reflected by the reflective film 12.
It is reflected at the front, refracted at the front, and directed to the side. As a result, side visibility is improved. Further, since the reflective film 12 and the paint 13 are located within the grooves of the base material, the lens can be made thinner, and the colored area required for design can be secured.

FIG. 5 shows a case where the groove side wall surface is a spherical surface with a radius R such that the inside of the groove is a convex surface, and FIG. Contrary to the case shown in FIG. 5, this is a case where the inside of the groove is a concave spherical surface with a radius R. In either case of FIG. 5 or FIG. 6, forming the reflective film 12 on the side wall surface and filling the groove with paint 13 is the same as in the case of FIG. 4, and the effect is also the same.

とができる。 As described above, according to the present invention, a fisheye cut is formed on the back surface of the lens base material, a substantially V-shaped groove is formed on the front surface, a reflective film is provided on the side wall surface, and an opaque color is formed inside the groove. Since the front lens is filled with paint, after some of the parallel incident light is reflected by the reflective film,
It refracts and travels laterally, improving lateral visibility. In addition, since the reflective film and paint are located within the grooves of the lens base material, the lens can be made thinner, and the colored area can be secured without interfering with forward irradiation, meeting design requirements. be able to.
