Under no pressure, the upper parts of the first vertical wall 11b and the second vertical wall 11c rebound. At this time, it can be seen from FIG. 6 that the upper limit groove wall of the lampshade buckle groove 13, the stop bar 111 and the lower limit groove wall are bonded and fixed to the buckle part of the lampshade 14 by sealing glue, effectively preventing the lampshade 14 from falling off.

Install the end caps 15 on both ends of the lamp body 11, and the end caps 15 fasten the two ends of the lampshade 14 and seal them with sealing glue;

Pass the power cord 6 out of the end cover 15;

A fixing bracket 7 is installed at the bottom of the lamp body 1 .

working principle:

The power line 6 is connected to the power supply, and the overall controller of the wall washer controls and outputs the light control signal, which is transmitted to the control module circuit, and the control module circuit converts the acquired light control signal into a corresponding constant current output signal, and converts The constant current output signal lamp bead lights up and displays different colors. The light emits a beam of light through the circular hole in the light-transmitting area.

In the present invention, the lamp body 1 of the LED wall washer lamp is an aluminum alloy lamp body, and the lampshade 14 is tempered organic glass. The aluminum alloy lamp body adopts the snap-back principle to tightly adhere the toughened glass lampshade 14 to the sealant.

Structurally, it can be seen from Fig. 6 that the lampshade 14 and the lamp body 1 are closely interlocked by using the guide inclined wall on the lamp body 11 to cooperate with the first vertical wall 11b and the second vertical wall 11c which have the principle of physical resilience, so as to prevent The glass lampshade 14 in the lampshade buckle groove 13 falls off.

In terms of operation, first apply a layer of waterproof sealant evenly on the buckle groove 13 of the lampshade; then press the lampshade 14 in parallel from the guiding inclined wall of the lamp body 1, and after the upper parts of the first vertical wall 11b and the second vertical wall 11c bounce off Resetting realizes that the lampshade 14 is closely interlocked with the lamp body 11 to ensure that the structure is tightly bonded before and after curing, so as to achieve the best sealing and waterproof effect.
