Patent ID: 8287144

Claim:
LED bar modules ( 2 ) comprising a number of LED groups, which LED groups comprise a number of LEDs ( 54 ), which LEDs ( 54 ) have different colours, which LEDs ( 54 ) are electrically connected to a colour controller for generating light with changing colours, which colour controller is connected to a power supply, where the power supply is formed at a main printed circuit ( 8 ), where the LED groups are placed at a pixel board ( 6 ), which pixel board ( 6 ) conducts heat from the LEDs ( 54 ), characterized in that the main printed circuit ( 8 ) is placed inside a heat conductive tube ( 4 ), where the pixel board ( 6 ) is placed outside the heat conductive tube ( 4 ) in a longitudinal recess ( 14 ), where a connector is electrically connecting the pixel board ( 6 ) to the main printed circuit ( 8 ), where the main printed circuit ( 8 ) is placed inside an isolation cover ( 12 ), which isolation cover ( 12 ) is placed between the main printed circuit ( 8 ) and the heat conductive tube ( 4 ), which isolation cover ( 12 ) has a longitudinal opening for achieving heat conduction between the main printed circuit ( 8 ) and a central part ( 16 ) of the upper wall of the heat conductive tube ( 4 ).
