Embodiments of an end-cap for an LED tube are described. In one aspect, an end-cap for an LED tube may include an end-cap housing, an elastic component, a power connector, and a movable assembly. The movable assembly may include a power pin thereon and configured to connect to an external power source. The elastic component may reside inside the end-cap housing. A first end of the movable assembly may connect to the end-cap housing. A second end of the connecting assembly opposite to the first end thereof may connect to a body of the LED tube through the power connector. The power connector may be electrically disconnected from the power pin when the end-cap housing is pressed. The power connector may be electrically connected to the power pin when the end-cap housing is not pressed.

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.
