Abstract: This paper presents a novel white light LED array equipped with a 3-pulse-width-modulation (PWM) control module that could separately adjust either the color temperature or luminous flux without influence on the other. An optical measurement system was set up to provide the complete information of color temperature, illuminance and spectrum of the LED array for analysis. The radiometry quantity of spectral data was converted into photometry quantity. The average percent deviations of color temperatures with a fixed illuminance, and illuminances with a fixed color temperature were estimated, respectively. Comparing with the existing commercial products, the developed LED array has better adjustability, stability and precision. The proposed innovations represent a novel solution for white light LED lighting technology and related applications.
