| Title: |
LED Bar |
| Abstract: |
The present invention relates to LED bar modules where the LED groups are
placed at a pixel board. The present invention further concerns a method
for calibration of LEDs. It is the object of the invention to achieve a
highly efficient LED bar for generating a bar of light. A further object
of the invention is to store calibration data for each LED both
electrically and mechanically close to the actual LED. Preferably, the
main printed circuit is placed inside a heat conductive tube, where the
pixel board is placed outside the heat conductive tube in a longitudinal
recess, where the main printed circuit is placed inside an isolation
cover. Hereby, it is achieved that the LEDs are placed on the outside of
the tube in a way where heat generated from the LEDs is conducted
downwards to the tube. Inside the tube, the rest of the power electronics
and also the light controlling electronics are placed.
