| Title: |
LED Bar |
| Abstract: |
An LED device in which LED groups are located on a pixel board has
calibration data for each LED stored both electrically and mechanically
close to the actual LED. Preferably, each LED group has a number of LEDs
of different colors on the pixel board, being electrically connected to a
color controller. The color controller is connected to a power supply,
and the pixel board has a memory circuit having the LED calibration data
related to the LEDs stored therein. The color controller controls LEDs
for generating light based on the LED calibration data stored in the
memory circuit on said pixel board. Preferably, at least one of the LEDs
is formed on a chip that contains the memory circuit for storing the
calibration data.
