Abstract
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.
