Light emitting element array |
摘要 |
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.
