Summary: | A lighting system includes one or more methods and systems to control the color spectrum of a lamp in response to both temperature and dim levels. In at least one embodiment, the lighting system includes a controller to control a correlated color temperature (CCT) and intensity of the lamp by independently adjusting currents to electronic light sources based on a dim level of the lighting system and temperature of the lighting system. The controller controls a first current to a first set of LEDs and a second current to a second set of LEDs. The control of the first current by the controller is jointly dependent on a dim level and temperature in the lighting system. In at least one embodiment, the control of the second current is dependent on the dim level or the dim level and temperature. |
