PROBLEM TO BE SOLVED: To improve the enviromental resistance and ultraviolet ray resistance of a semiconductor light emitting device. SOLUTION: In a semiconductor light emitting device provided with a pair of wiring conductors (3, 4), a semiconductor light emitting element (2) fixed to one ends of the pair of wiring conductors (3, 4) as well as a photo- transmissible insulator sealing body, the insulator sealing body is composed of a glass layer (10). In such a constitution, granular fine crystal grains (10a) having phototransmittancy to the irradiated beams from the semiconductor light emitting element (2) as well as made of a fluorescent material absorbing the beams irradiated from the semiconductor light emitting element (2) and converting into the other light emitting wavelength are mixed in the glass layer (10). Besides, the external light emission is performed by converting into specific light emitting wavelength using the granular fine crystal grains (10a) comprising the fluorescent material in the glass layer (10) through the glass layer (10) and a sealing resin (8) encircling the semiconductor light emitting element (2). |
