Abstract :
In this paper, the algorithm for the stepless tunable four-chip LED on the black body radiation curve, using the Generalized Reduced Gradient method, is proposed. The lumen outputs of four-chip LED, for color temperatures between 2500K and 6500K, are then calculated in real-time, without using a lookup table, and for high quality lighting design.
