A method for producing a light mixing box in which a number of light-emitting diodes is statistically determined, corresponding lighting device and set of lighting devices

摘要

Method for producing a light mixing box (1; 7; 8; 9; 10) having a cavity and a light exit opening (6), the cavity (3) being equipped with a reflecting surface and having a plurality of light emitting diodes (4) in the cavity (3) with at least two different colors, the light emitting diodes (4) being selected from different bins for at least one color; bins representing selection areas within a color chart whose color or color temperature has a certain uniformity or whose color does not vary excessively; Method comprising at least: - selecting light emitting diodes (4) of each color from respective bins; - statistically determining the number of light emitting diodes (4) of each color to obtain a desired color location and a desired value of luminous flux within a respective predetermined tolerance range the desired color locations and / or desired brightness values and the associated tolerances of the egg nzelnen light-emitting diodes are known and wherein the number of participating in the generation of the mixed light LEDs is selected so high that the tolerance or deviation of a setpoint statistically reduced so that the desired color location or the desired brightness is achieved with the desired tolerance ; and - equipping the light mixing box (1; 7; 8; 9; 10) with light-emitting diodes (4) in at least the statistically determined number.
