ABSTRACT:
There is provided a white light emitting device that prevents a red phosphor from resorbing wavelength-converted light to improve white luminous efficiency. A white light emitting device according to an aspect of the invention includes a package body; at least two LED chips mounted to the package body and emitting excitation light; and a molding unit including phosphors, absorbing the excitation light and emitting wavelength-converted light, in regions of the molding unit divided according to the LED chips and molding the LED chips. According to the aspect of the invention, since the phosphor for converted red light can be prevented from resorbing light generated from other regions of the molding unit, the white light emitting device that can improve white luminous efficiency or control color rendering and color temperature by adjusting a mixing ratio of converted light for white light emission.
