  • METHOD FOR MAXIMIZING THE PERFORMANCE OF A LUMINAIRE
    Publication number: 20110241552
    Abstract: A method for maximizing the performance of a luminaire (1) emitting light is provided, which method comprises determining a target color point (T) corresponding to a predetermined color, providing a first light source (2) emitting light at a fixed reference color point (W), and providing a second light source (4) being able to emit light at an adjustable color point (RGB). Said adjustable color point (RGB) is selected such that a combination of light emitted by the first and the second light sources (2, 4) together produces light at the target color point (T), wherein the adjustable color point (RGB) is selected based on the position of the target color point (T) and the reference color point (W) for maximizing the performance of the luminaire (1). With the provision of a solution in accordance with the present invention, fewer computations need to be performed in order to maximize the illumination performance of the luminaire (1).
