Color correlated temperature correction for LED strings |
摘要 |
<p>An array of LEDs having output light in different wavelength ranges. A control circuit connected to the array includes a temperature variable resistance component and a switch selectively connecting the component to the array. The control circuit limits the current applied to at least some of the LEDs during initial energization of the LEDs prior to steady-state operation of the LEDs. Variations over time of a color correlated temperature (CCT) of output light of the energized array are reduced.</p> |
