More Information
Summary:Systems to control light color temperature during dimming are disclosed. A power supply drives a load include a first light source (e.g., to emit a first color of light) and a second light source (e.g., to emit a second color of light). The power supply includes a front end circuit, a converter circuit, and a load current control circuit. The front end circuit receives an input voltage from a dimmer and generates a direct current (DC) voltage based on the received input voltage. The converter circuit generates a first voltage to drive the first light source and a second voltage to drive the second light source. The load current control circuit controls the current flowing through the second light source based on a light control setting configured in the dimmer.
