1. Prepare the light box profiles, corner codes, screws and screwdrivers, then align the corners of the light box profiles cut to 45 degrees in advance diagonally, then splice them together with corner codes, and fix each corner with two screws, so that the light box frame is assembled.

2. If the light box is directly installed on the wall, it can be installed without backboard. First, fix the bracket of the light box on the wall with screws, and then hang the frame of the light box that we fixed in advance on the bracket of the light box.

3. The installation of 3.led strips is similar to the installation of light boxes. First, connect the hook with the light bar with a cable tie, then hang the led light bar on the profile of the light box, and install a power supply (gray wire positive electrode, white wire negative electrode) on the edge of the outer frame where the socket is located.

4. Hang the light bars on both ends of the profile respectively to complete the installation. Finally, put on the canvas. There is a silicone rubber strip around the canvas. Just embed the silicone rubber strip into the aluminum frame.
