Abstract
A light emitting element array has light emitting elements disposed on a base plate in an array and a rod-like converging lens is disposed adjacent and parallel to this array. The end surfaces of this rod-like lens are curved, or otherwise so shaped that light beams from the array are refracted towards the center of the lens, thereby increasing the relative distance on a target surface that can be effectively irradiated.
Claims5
In a light emitting element array having a plurality of light emitting elements disposed on a base plate in an array and a rod-like converging lens disposed parallel to said array of said light emitting elements, the improvement wherein said rod-like converging lens has end surfaces which are so shaped as to refract light beams from said light emitting elements into central directions.
