An LED lighting module (10) comprising an LED module having one or more single LEDs (20) on a first printed circuit board (PCB) (14), a heat sink (16), and a second printed circuit board (18) is disclosed. The first printed circuit board (14) is in good thermal contact with the heat sink (16) such that heat from the LED(s) (20) is dissipated through the heat sink (16). The second printed circuit (18) is adapted to accommodate the power and control circuitry for the LED(s) (20), and is thermally insulated from both the heat sink (16) and from the first printed circuit board (14) and thus from the LED module. By separating the LED PCB (14) from the control circuitry and components required to power and control the LED (20), it is possible to increase the light output and/or increase the lifespan of the LED lighting module (10). |
