PURPOSE: A light emitting device is provided to obtain white light having a color rendering index approximating to a solar spectrum by mixing blue light emitted from a blue light emitting LED, green light emitted by a first fluorescent material, and red light emitted by a second fluorescent material. CONSTITUTION: A circuit board(2) includes a wiring pattern(7) formed at a base substrate(6) and an upper side of the base substrate. The wiring pattern electrically connects a power source terminal with a terminal of a light emitting diode(3). The light emitting diode is electrically bonded with the wiring pattern through a wire(8). A housing(4) is formed into a hoop shape that surrounds the light emitting diode. A fluorescence lamination layer(5) is installed in order to close a top end portion of the housing. |
