Allochromatic light emitter
First Claim
1. An allochromatic light emitter, comprising:
- an emitter casing with a light exit port;
a fluorescent substance formed by an LED grid, said LED grid having a plurality of LEDs divided into no less than two LED groups, with the LEDs of an LED group emitting light of a wave length differing from the wave length of the emitted light of another LED group;
a controller for controlling the color of the light reproduced on a target plane with an electronic control providing various LED groups independently of one another with a respectively variable operating voltage with the relationships of the operating voltages of different LED groups controlled and/or regulated with respect to one another in accordance with a color to be reproduced on a target plane.

Abstract
An allochromatic light emitter (1) including an emitter casing (2) with a light exit port (3) and further including a fluorescent element provided in the emitter casing and a controller controlling the color of the light reproduced on a target plane. The fluorescent element is formed by an LED grid (4), with the LED grid (4) having a plurality of LEDs (5), wherein the plurality of LEDs (5) is divided into no less than two LED groups (6, 6′, 6″), with the LEDs (5) of an LED group (6) emitting light of a wave length which is different from the wave length of the emitted light of another LED group (6′, 6″). The controller includes an electronic control (7) providing different LED groups (6, 6′, 6″) independently of one another with a respectively variable operating voltage (U, U′, U″). The relationships of the operating voltages (U, U′, U″) of different LED groups (6, 6′; 6″) are controlled and/or regulated in accordance with a color to be reproduced on a target plane.
