A light emitting device of the present invention includes at least: at least more than one blue light chip, at least more than one red light chip and a fluorescent layer overlaid and bonded to the blue light light chip and the red light chip. The fluorescent layer is formed from a uniform mixture of a yellow phosphor and a red phosphor with the addition of a transparent plastic material. At least one portion of the absorbed light source is used to emit a light source with a wave length dissimilar to the wave length of the absorbed light or of the same wave length, thereby achieving the effectiveness to increase the illuminance and color rendering of white light.
