THREE-PRIMARY COLOUR LED LAMP WITH DIFFERENT LIGHT-EMITTING SURFACES

摘要

A three-primary colour LED lamp with different light-emitting surfaces, which has three primary colours, i.e. RGB. The surface curvatures of the light-emitting surfaces of each lamp of the RGB lamp are different. The light-emitting surfaces are variable-radius light-emitting surfaces. The refraction angles of all lamps of the three-primary colour, i.e. RGB, lamp on the light-emitting surfaces coincide. Different light-emitting surfaces are used to compensate for different refraction angles when directions of light deviating from a normal are different, so that when RGB light with different wavelengths passes through the light-emitting surfaces, the light emitted at any angle does not generate a difference due to different refraction angles.
