Abstract

A polychrome lighting device, including at least one light source for each one of the three primary colors and elements for adjusting the light sources, the adjustment elements being adapted to independently control the adjustment of the luminous intensity of the light sources in order to combine the light beams emitted by the sources into a light beam having the desired shade of color, remote control elements being also provided for setting, storing, and retrieving desired luminous intensity values of the light sources and therefore desired light colors.

Claims

1. A polychrome lighting device, comprising:

at least one light source for each one of three primary colors;

a white-light source;

adjustment means for adjusting said light sources, said adjustment means independently controlling adjustment of luminous intensity and light flux of said light sources to combine light beams emitted by said sources into a light beam having a desired shade of color;

remote control means for controlling said adjustment means, said remote control means setting, storing, and retrieving desired values of the luminous intensity of each one of said light sources, said remote control means comprising data storing means for storing a plurality of combinations of luminous intensity settings of said light sources in order to allow reproducing of preset and user-set lighting conditions; and

said adjustment means comprising a microprocessor and signal detection means, said signal detection means detecting signals sent by said remote-control means.

2. The device according to claim 1, comprising three light sources, each source having a filter for obtaining the three primary colors.

3. The device according to claim 1, wherein said signal detection means comprises an infrared sensor.

4. The device according to claim 1, comprising lighting circuits with power control for driving each one of said light sources, through said adjustment means.

5. The device according to claim 4, wherein said lighting circuits with power control comprise triacs.

6. The device according to claim 3, wherein said adjustment means comprises nonvolatile memory means, said memory means being connected to said microprocessor, said remote control means comprising a further microprocessor.

7. The device according to claim 1, comprising power supply means for powering said microprocessor.

8. The device according to claim 1, wherein said remote control means comprises means for displaying set functions.

9. The device according to claim 1, wherein said remote control means comprise a microprocessor, said means for storing data, and means for entering data for setting luminous intensity values which are independent for each one of said light sources and for retrieving luminous intensity value combinations which are preset or set by a user.

10. The device according to claim 1, wherein said light sources are orientated in a fixed fashion in the same direction.

11. The device according to claim 1, wherein said light sources are orientatable in different directions.

12. The device according to claim 1, wherein said remote control means are radio control means.
