The paper illustrates the design of a white light solid state lamp, presenting a controlled quality of the emitted luminous flux in terms of both luminance and color temperature. Exploiting the same principle of color mixing adopted in RGB light sources, the designed fixture is based on three LED arrays implementing two primary color emitters (red and green) and a cool white light source. The regulation of intensity and color temperature is achieved by independently adjusting, by PWM dimming… CONTINUE READING
