Abstract

A light emitting device is provided. The device includes a red light emitting unit, a blue light emitting unit, a green light emitting unit, and a white light emitting unit. The red light emitting unit includes a first blue light emitting chip and a red fluorescent material, and a dominant wavelength of a light emitted by the red light emitting unit is in a range of 615 nanometers (nm) to 635 nm. By designing the light emitting device into a structure including the red light emitting unit, the blue light emitting unit, the green light emitting unit and the white light emitting unit, and designing the structure of the red light emitting unit, the light emitting device can realize the adjustment of ambient light and color temperature by the four light emitting units, thereby reducing cost.
