<P>PROBLEM TO BE SOLVED: To have reduced loss in the case of radiation emission or radiation-input coupling and comparatively advanced stability for ultraviolet radiation to be had by improving a beam shaping element, in a light emitting semiconductor chip 2 provided with the beam shaping element. <P>SOLUTION: The beam shaping element comprises an hollow body 1 provided with a light emission hole 7 and a light entrance hole 8 opposed to the light emission hole, and a semiconductor chip is in contact with the light entrance hole of the hollow body 1 or penetrates into the hollow body through the light entrance hole. The light emitting semiconductor chip is constituted so that the semiconductor chip emits electromagnetic radiation 3 into the interior of the hollow body, and at least a part of electromagnetic radiation reflects on a wall section 6 of the hollow body toward the light emission hole. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
