Abstract:
A light-emitting device (100), comprising a first LED array (10), a second LED array (20), a third LED array (30), and a light-combining component (40). The first LED array (10) comprises a blue-light LED (11) and a cyan-light LED (12), and the blue-light LED (11) and the cyan-light LED (12) are respectively configured to emit blue light and cyan light; the second LED array (20) comprises a green-light LED (21), and the green-light LED (21) is configured to emit green light; the third LED array (30) comprises a red-light LED (31), and the red-light LED (31) is configured to emit red light; the light-combining component (40) is configured to receive the blue light, the cyan light, the green light, and the red light, so as to emit white light. The cyan-light LED (12) and the blue-light LED (11) are simultaneously provided in the first LED array (10), thereby increasing a primary color light source of the light-emitting device (100) and being capable of providing the white light having wider gamut and higher color rendering.
