DEVICE FOR GENERATING LIGHT WITH A VARIABLE COLOR

摘要

An illumination system (100) comprises: a lamp assembly (14); a controller (115); a user input device (19); a memory (120) defining discrete color points, containing a ID hue table (121), a ID saturation table (122), a ID brightness table (123), and a boundary memory (124) defining a boundary of the color space. On the basis of data (xl,x2,x3) received from the user input device and on the basis of the information in the memory, the controller generates color control signals (?l, ?2, ?3) for the lamp assembly. The controller compares the user input data with the information in the boundary memory. If the controller finds that said point is located outside the boundary of the color space, the controller calculates a replacement point on the color space boundary as defined in the boundary memory (124), and generates its control signals on the basis of the replacement point.
