WARM DIMMING FOR AN LED LIGHT SOURCE |
摘要 |
A lighting device includes a first LED light source having a first color temperature, a second LED light source having a second, lower color temperature connected in parallel with the first LED light source, and control circuitry operable to apply variable duty cycle frequency modulated power to the first LED light source while continuous power is provided to the second LED light source. A method of operating a lighting device includes providing variable duty cycle frequency modulated power to a first LED light source having a first color temperature, and providing continuous power to a second LED light source having a second, lower color temperature connected in parallel with the first LED light source. |
