A lamp, including: a plate, material thereof being optically transparent, the plate including two parallel surfaces and at least one rough width surface for illuminating outside the lamp; a plurality of illuminating sources disposed adjacent and along at least another width surface of the plate; and a user-movable shutter, for covering any of the plurality of illuminating sources, thereby the at least one rough width surface is uniformly illuminated, and thereby moving of the shutter adjusts intensity of the uniform illumination.

Provided is a power adapter for strip lights having a control function, comprising a main housing, a PCBA, wires, and pins; wherein one end of the wire is electrically connected to the PCBA while the other end is provided with a connection seat for connecting strip lights; the pins partially protrude out of the front face of the main housing; the PCBA is electrically connected with an indicator light which partially protrudes out of the rear face of the main housing; the PCBA has a main control unit which is connected with a power management module, a light control module, an infrared receiver, and a wireless communication module.
