LUMINESCENT COLOR-CONVERTING MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a luminescent color-converting member from which a highly reliable and highly durable white lighting source can be obtained even if a blue LED device, especially a high power one, is used.

SOLUTION: This luminescent color-converting member converts a part of a blue light emitted from a blue light source to a yellow light and mixes the yellow light with the rest of the blue light to obtain a white light. It is obtained by dispersing an inorganic phosphor in a glass whose softening point is higher than 500°C and has a thickness of not less than 0.2 mm.
