Abstract: A semiconductor light emitting device includes 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 electrodes and the semiconductor light emitting element, a reflector extended from a bottom of the base substrate to a predetermined height for surrounding the semiconductor 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.
