LED lighting device with replaceable driver-control module

摘要

An LED lighting device with a replaceable driver-control module interface is described. The LED lighting device may include a driver-less LED lighting device, a driver-control module with driver function, and a housing interface on the driver-less LED lighting device to house and connect the driver-control module. The driver-less LED lighting device receives AC from an external AC source and passes the AC to the driver-control module. The driver-control module receives AC from the driver-less LED lighting device and provides DC to the driver-less lighting device to drive LED diodes in the driver-less LED lighting device. The housing interface on the lighting device houses the driver-control module such that, when the driver-control module is fastened to the driver-less lighting device through the housing interface, the driver-control becomes an integral part of the lighting device.
