| titleOfInvention | lighting device |
| abstract | Provided herein is a lighting device including a first LED, a second LED and a control unit. The first LED emits white light. The second LED emits white light, the correlated color temperature of the white light emitted from the second LED is lower than the correlated color temperature of the white light emitted from the first LED, and the chromaticity deviation of the white light emitted from the second LED is higher than that of the white light emitted from the first LED chromaticity deviation of white light. The control unit changes the light output ratio of the first LED and the second LED. The correlated color temperature of the white light emitted by the first LED is in the range of 1563K to 4500K, and the chromaticity deviation thereof is in the range of -1.6 to -12. The correlated color temperature of the white light emitted by the second LED is in the range of 1563K to 4500K, and the chromaticity deviation thereof is in the range of +10 to -1.6. |
