The front side cover of the mounting cavity 2 is provided with a transparent waterproof cover 5, and the front side cover of the mounting plate 1 is provided with a fastening plate 6, and the fastening plate 6 is provided with a light-transmitting hole 60 for the waterproof cover 5 to extend.

[0033] During installation, the circuit board is installed in the installation cavity 2, and then the waterproof cover 5 is fastened and bolted to the desired longitudinal installation surface. Finally, the fastening plate 6 is placed on the installation plate. The fastening plate can press the waterproof cover tightly, achieving a tight fit on the front side of the installation cavity, ensuring good waterproof performance and preventing moisture and dust from entering.

[0034] Preferably, the installation cavity 2 includes a plate cavity 21 and a component cavity 22 that are connected from top to bottom. The side wall of the plate cavity 21 is provided with a plug-in slot 210 for plugging in the circuit board 3.

The two sides of the circuit board 3 above the component group 30 are plugged into the plug-in slot 210.

[0035] In the above structure, the circuit board 3 is installed by plugging in. The circuit components are assembled in the rear area of ​​the circuit board, and the LED lamp beads 4 are assembled in the front area, so that the LED lamp beads can light up the front side for better effect. At the same time, the component group 30 is close to the installation cavity 2, and the component group can be effectively protected to ensure the service life of the components.

[0036] Preferably, the longitudinal cross-section of the circuit board 3 is a “T”-shaped structure, a lamp bead mounting plate 32 is formed on the front side of the circuit board 3 , and a plurality of the lamp beads 4 are evenly distributed at the bottom of the lamp bead mounting plate 32 .

[0039] The arrangement of the lamp bead cavity 50 enables the lamp bead mounting plate to protrude forward during installation. The structural adaptation of the lamp bead cavity 50 provides effective protection for the lamp bead mounting plate.

[0040] Preferably, the edge of the installation cavity 2 is formed with an installation inner edge 24, and the waterproof cover 5 is connected to the installation inner edge 24 by ultrasonic welding. The ultrasonic welding method is efficient and economical.

[0041] Preferably, the lower edge of the light-transmitting hole 60 extends backward to form a retaining edge 61 that abuts against the bottom of the lamp bead cavity 50. The light-transmitting hole 60 is horizontally opened. The retaining edge 61 can abut against the lower end of the lamp bead cavity 50, thereby making the waterproof cover fit better and ensuring waterproofness.
