METHOD FOR MIXING LIGHT OF LEDS AND LIGHTING DEVICE USING SAME |
| 摘要 |
A method for mixing light of LEDs includes following steps: Firstly, a substrate with a red light LED, a green light LED and a blue light LED arranged thereon is provided. Secondly, a power source for supplying power to the red light LED, the green light LED and the blue light LED is provided. Thirdly, a temperature variation ΔT1 of the red light LED caused by the power source, a temperature variation ΔT2 of the green light LED caused by the power source, a temperature variation ΔT3 of the blue light LED caused by the power source are calculated. And finally, input currents applied to the red light LED, the green light LED and the blue light LED are adjusted according to the temperature variations ΔT1, ΔT2 and ΔT3. A lighting device using the method is also provided. |
