More Information
Summary:An illumination module includes a color conversion cavity with a first interior surface having a first wavelength converting material and a second interior surface having a second wavelength converting material. A first LED is configured to receive a first current and to emit light that preferentially illuminates the first interior surface. A second LED is configured to receive a second current and emit light that preferentially illuminates the second interior surface. The first current and the second current are selectable to achieve a range of correlated color temperature (CCT) of light output by the LED based illumination device.
