  • Patent number: 9989239
    Abstract: An LED downlight lighting module is provided including an LED module having one or more single LEDs on a first printed circuit board, a heat sink, and a second printed circuit board. In an embodiment, the first printed circuit board is in good thermal contact with the heat sink such that heat from the LEDs is dissipated through the heat sink. In an embodiment, the second printed circuit board is adapted to accommodate a power and control circuitry for the LEDs, and is thermally insulated from the heat sink and from the first printed circuit board, and thus from the LED module. According to an aspect, the LEDs serve as the principal heat generating component on the printed circuit board, thus helping to increase the light output from the LEDs and/or increase the lifespan of the LED downlight lighting module.
