LED REAR LAMP, IN PARTICULAR FOR A BICYCLE

摘要

The present invention relates to a LED rear lamp comprising a light guide (1) arranged in or forming part of a housing (10), said light guide (1) having a plate-like shape with a central aperture (2) surrounded by an inner side face (9) of the light guide. One or several LEDs (3) are arranged in the central aperture (2) such that a main emission direction of each LED (3) is aligned towards the inner side face (9) to couple emitted light through the inner side face (9) into the light guide (1). The light guide (1) is designed to guide a first portion (5) of the emitted light to escape through at least two opposing outer side faces (4) of the light guide (1) and to internally reflect or scatter a second portion (6) of the emitted light traveling towards the two outer side faces (4) to escape through a main surface (7) of the light guide (1). With the proposed LED rear lamp a good rear and side visibility is achieved in an efficient manner.
