The present disclosure provides a power supply device and a high-power illumination system. The power supply device includes: a housing, where the housing includes a first bottom plate having a first surface on which a first heat sink is provided and a second surface on which a thermal conductive potting layer is provided; and a printed circuit board, where the printed circuit board is located in the housing, the printed circuit board includes a circuit board body and multiple electronic components arranged on the circuit board body, at least part of the multiple electronic components is arranged facing the second surface of the first bottom plate, and the electronic component of the at least part of the multiple electronic components is partially immersed in the thermal conductive potting layer to conduct heat dissipated by the electronic component to the first heat sink for natural heat dissipation of the electronic component.

Power supply device and high-power illumination system

A light module and a manufacturing method are provided. The light module comprises a first and a second substrate separated from a prefabricated substrate along a closed curve, the first substrate is detachable connected and/or fixed with the second substrate; light emitting elements mounted on one of the first and second substrate; and a drive element mounted on the other one of the first and second substrate. The method comprises: determining a closed curve on a prefabricated substrate to separate the prefabricated substrate into a first region and a second region; providing light emitting elements and first electronic element on first surface of the prefabricated substrate; providing second electronic element on second surface of the prefabricated substrate; separating a first and second substrate from the prefabricated substrate along the closed curve; and assembling and connecting the second substrate with the first substrate at a separation opening.
