This study proposes an algorithm for calculating the outputs of a stepless, tunable, four-chip LED according to a black body radiation curve; the proposed algorithm is based on the generalized reduced gradient method. The lumen outputs of the four-chip LEDs were calculated in real time at color temperatures ranging between 2500 K and 6500 K without using a lookup table, enabling achieving high-quality...
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.
