LIGHT REFLECTOR AND METHOD OF DIFFUSING THE REFLECTING LIGHT OF A LIGHT REFLECTOR
First Claim
1. A light reflector comprising the combination of a light transmitting reflecting member, said member having a smooth front surface and a rear surface, a plurality of reflecting elements formed on said rear surface, said reflecting elements being of two varieties, a first variety comprised of reflecting elements having three reflecting planes positioned such that lines normal thereto intersect each other at right angles wherein reflected light rays are reflected therefrom in a direction parallel to light incident thereon and a second variety of reflecting elements having three reflecting planes positioned such that lines normal thereto intersect in a skewed manner while optical axes thereof intersect each other at right angles, wherein light rays incident thereon are reflected therefrom in a skewed direction relative to said incident rays, said first variety of reflecting elements being positioned centrally of said rear surface and said second variety of reflecting elements being positioned in the surrounding said central region, whereby light is diffused to provide comprehensive viewing of said reflector from locations not in line with incident light source and said reflector.

Abstract
A light reflector which diffuses its reflecting light rays received from external light sources such as headlight lamps of vehicles, is disclosed. The reflector comprises a light transmitting reflecting member made of a synthetic resin and having a smooth front surface and a rear face with a number of reflecting elements formed in adjacent relation thereon, each of said reflecting elements being comprised of three reflecting planar surfaces arranged so that their normal lines deviate by a desired angle from the optical axes X, Y, Z of the element which cross each other at right angle, whereby the light rays reflected and emitted from these elements are not reflected in a line parallel to the light rays incident to the respective reflecting elements.
