Light guide parts for lighting fixtures

Abstract

This product is a light guide part for lighting equipment, consisting of a small entrance part in the shape of an elliptical truncated cone with a gentle slope and a larger tapered part in the shape of an elliptical truncated cone with a steeper slope. This product takes in as much light as possible from a light source such as a light-emitting diode through the entrance part, guides the light to the irradiation surface, which is the bottom surface of the tapered part, and irradiates a uniform elliptical light beam from the irradiation surface to the front. In the reference diagram showing the state of use, this product is drawn in blue, but in reality the entire product is a solid transparent body.
