| 英文摘要 | PURPOSE:To easily obtain necessary illumination even from a comparatively small number of light-emitting elements and to enable a desired area to be illuminated with approximately uniform illumination, by disposing light-emitting elements and lenses so that lights projected from the respective light-emitting elements through the corresponding lenses are partially superposed on the illuminating area. CONSTITUTION:Convex lenses 2 are disposed in front of respective light-emitting elements 1 disposed at proper intervals. These lenses 2 prevent divergence of lights emitted from the light-emitting elements The function required for the lenses 2 is only to reduce divergence of the lights, and it is not necessary for them to parallelize and condense the lights. Mutual spacing of the light- emitting elements 1 and the position of the lenses 2 are regulated so that lights emitted from the respective light-emitting elements 1 are partially superposed on an illumination area and a distribution of light intensity is obtained as uniformly as possible. The distribution of light intensity given by one light-emitting element 1 is shown by I1, and that of light intensity synthesized by the whole of a plurality of light-emitting elements 1 is shown by I. |
