<P>PROBLEM TO BE SOLVED: To radiate outside the light emitted from a light emitting element at constant intensity from the surface of an enclosure. <P>SOLUTION: A rough side is formed at an interface between the air and a sealing resin 3. The rough side has such shape that compensates a light intensity distribution (c) on the interface to a light intensity distribution (a). The interface of the sealing resin 3 is formed in an uneven pattern such as the light intensity distribution (c) being inverted and transferred upside down, for providing characteristics of the light intensity distribution (a). Since, at an interface (b), the area just over the light emitting element 1 in the light intensity distribution (c) is the strongest in light intensity, that portion of the interface is concave while its surroundings where the light intensity becomes weaker are convex. <P>COPYRIGHT: (C)2007,JPO&INPIT |
