| Title: |
Lighting Device Comprising a Plurality of Controllable Light-Emitting Diodes |
| Abstract: |
A lighting device comprising a plurality of lighting modules which
include a module carrier on which a light source with a plurality of
controllable light-emitting diodes emitting light of different
wavelengths and arranged on a board, a temperature sensor and a module
electronic are arranged. Said module electronic contains a digital
circuit with a microcontroller for the local and autonomous signal
processing, which actuates the LEDs in dependence on the temperature such
that the brightness, color and chrominance of the light mixture composed
of the LEDs emitting light of different wavelengths is constant. Said
lighting modules being connected with other lighting modules or an
external controller via a digital interface for transmitting the board
temperature of the respective lighting module detected by means of the
temperature sensor. A central master module or the external controller
actuates the lighting modules such that a uniform brightness is obtained
over the radiating surface.
