Abstract:
1. A semiconductor light emitting device comprising: a base substrate; lead electrodes provided on the base substrate; at least one semiconductor light emitting element loaded on the base substrate so as to be spaced apart from the lead electrodes and radiating blue light; a connection member for electrically interconnecting the lead electrodes and the semiconductor light emitting element; a reflector extended from a surface of the base substrate to a predetermined height for surrounding the semiconductor light emitting element, the reflector being made of a metal plate having an insulation film formed on at least a part of a surface thereof so as to reflect the light radiated from the light emitting element and form a uniform planar light, having high reflectance and high thermal conductivity, the reflector discharging the heat radiated from the light emitting element to outside so as to cool an inside of a receiving space for receiving the light emitting element; and a translucent cover layer formed in the receiving space for housing the light emitting element, the translucent cover layer containing a color-shifting substance for absorbing at least a part of blue light radiated from the light emitting element to radiate a light having a different wavelength, whereby the device emits white light by combination of the blue light radiated from the light emitting element and the light having a different wavelength.
