LED lamps for general room lighting is increasingly popular due to their many advantages including their tunability and color mixing abilities over their predecessors of halogen and fluorescent bulbs. Studies have shown that different color lighting have various effects on humans, but room lighting conditions can vary due to LED color shift or other lighting factors. This paper presents a novel closed-loop control algorithm using a typical Android smartphone camera to control an RGB luminaire. When tested in a controlled lab environment, it was able to produce an average chromaticity difference Δu′,v′ of 0.0225 to the selected colors.
