Abstract :
The white light based on the mixed RGB LEDs with relative position of isosceles right-angle triangle was simulated and investigated in the paper. The colorimetric characteristics of white light were analyzed. The results show that the chromaticity coordinates x increases, y decreases, the chromaticity coordinates shift to red region and color temperature decline with side length of the isosceles triangle increases. When distance between receiving surface and RGB LEDs increase, both of x, y of chromaticity coordinates increase and the color temperatures are changed in small ranges.
