LIGHT-EMITTING DEVICE |
| 摘要 |
Disclosed herein is a light-emitting device that includes a blue light source, a first phosphor and a red light source. The blue light source emits blue light. The first phosphor is excited by the blue light to emit light that is then combined with the blue light to produce first white light. The first white light falls in a first region of (0.397, 0.502), (0.337, 0.512), (0.26, 0.34), and (0.313, 0.3334), based on a CIE 1931 color coordinate standard. The red light source emits red light to adjust the first white light into second white light. |
