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).

Description

technical field [0001] The present invention relates to a method for maximizing the performance of a luminaire emitting light with a predetermined color. The invention also relates to the above-mentioned luminous body, the computer program and the computer program product for carrying out the above-mentioned method. Background technique [0002] Advances in the development and improvement of the luminous flux of light emitting devices, such as LEDs, have made these devices suitable for use in general lighting applications. For lighting, it is often important to have high luminous efficiency and / or good color rendering. The color rendering index (CRI) is a quantitative measure of the ability of a light source to faithfully reproduce the color of various objects as compared to an ideal or natural light source. CRI is the CIE (International Commission on Illumination) scale used to indicate the color rendering accuracy of a light source compared to a reference source of the s...
