Abstract: A screw-free modular design lighting fixture with interchangeable parts includes a lens cover, a round cover, a PCB, and the heat sink that make up the module, as well as a driver, a fastener on the driver, a frame, and a push release mechanism to secure the driver onto the module, then the module onto the frame to form the fixture. The lighting fixture uses push-release, clip on, twist on, click in, slide in, hinge-on, and other screw-free mechanisms to assemble, interchange, and maintain the module, frame, and drivers, in order to change the applications, light distributions, wattages, voltage, and other needs of the fixture.
