摘要
A light source can include an LED configured to emit light having a spectrum of first wavelengths when provided with electrical current, a pumped material configured to absorb at least some of the light emitted by the LED and to emit light having a spectrum of second wavelengths, a power supply configured to provide a series of electrical current pulses to the LED, and a current controller configured to control a time-averaged chromaticity coordinate of a combination of light emitted from the LED and the pumped material by controlling the series of current pulses provided to the LED.
