Preferably, the light box is also provided with an electrical cover covering the LED module and the electrical box; a second waterproof device is added to further improve the waterproof effect.

Preferably, the front end of the electrical cover is hinged to the light box, the rear end of the electrical cover is detachably connected to the electrical box, and the electrical box is detachably connected to the light box; it is convenient to open and close the electrical cover, and it is convenient to adjust the light Repair or replace the equipment in the box.

Preferably, bayonet sockets are provided on the left and right side walls of the light box to connect adjacent light boxes side by side; multiple street lamps can be connected side by side through the bayonet sockets.

Preferably, the front side wall of the light box is also provided with a bayonet, and the left and right side walls and the front side wall of the light box are all snapped with side light bars through the bayonet; Install side light strips for diffused lighting and decoration.

Preferably, at least one heat-dissipating convex strip is evenly distributed on the electrical cover above the LED module, and the heat-dissipating convex strip is integrally manufactured with the electrical appliance cover; the heat-dissipating convex strip is convenient for reducing the temperature in the light box, and the integrated manufacturing can prevent water leakage occur.

Preferably, the bottom of the light box is also provided with a mounting bar, and the electrical box is fixed on the mounting bar by bolts; it is beneficial to reduce the thickness of the bottom of the light box and strengthen the strength of the light box installed with the electrical box.

Compared with the prior art, the utility model has the advantages that: the structure of the device is simple, by setting a boss at the opening of the electrical box, covering the boss with a sealing ring, and then matching with the sealing groove on the electrical cover. Achieve a high sealing effect, protect the important electrical control parts of the LED street lamp under outdoor working conditions from water ingress, prolong the service life of the LED street lamp, and reduce the failure rate.

detailed description

Referring to Fig. 1, it is an embodiment of an LED street lamp of the present invention. An LED street lamp includes a light box 1, an LED module 2 is arranged inside the light box 1, and the light box 1 is located below the corresponding LED module 2. It is transparent or transparent to ensure that the light of the LED module 2 can be irradiated below. The light box 1 behind the LED module 2 is provided with an electrical box 3, and the electrical box 3 is provided with an upward opening. Electrical appliance cavity 4, as shown in Figure 2, the electrical appliance box 3 is also provided with an electrical appliance cover 5 that closes the electrical appliance cavity 4, and the opening of the electrical appliance cavity 4 on the electrical appliance box 3 is provided with a circle of upward bosses 6, The boss 6 is covered with a sealing ring 7, and the electrical cover 5 is provided with a sealing groove 8 at a position corresponding to the boss 6, and then the electrical cover 5 and the electrical box 3 are tightly fixed together by bolts, The light box 1 is also provided with an electrical cover covering the LED module 2 and the electrical box 3, the front end of the electrical cover is hinged to the light box 1, and the rear end of the electrical cover is detachably connected to the electrical box 3, so that The electrical appliance box 3 is detachably connected to the light box 1, and at least one heat dissipation convex strip 11 is evenly distributed on the electrical appliance cover above the LED module 2, and the heat dissipation convex strip 11 is integrally manufactured with the electrical appliance cover. 1 The bottom is also provided with a mounting bar 12, and the electrical box 3 is fixed on the mounting bar 12 by bolts.

The left and right side walls of the light box 1 are provided with bayonet sockets 9 connected side by side with adjacent light boxes 1, which can be used to connect multiple LED street lights in parallel. The bayonet 9 can be used to install the side light bar 10, which not only serves the purpose of diffusing the light source, but also plays a decorative role. The bayonet 9 can also be provided on the front side wall of the light box 1 to install the side light bar 10. .

Fix the electrical box 3 on the installation bar 12, then connect the LED module 2 with the control unit in the electrical box 3, then fix the LED module 2 in the light box 1, and give the boss 6 of the electrical box 3 Wrap the sealing ring 7, then align the sealing groove 8 of the electrical appliance cover 5 with the sealing ring 7 and cover tightly, then fasten the electrical appliance cover 5 and the electrical box 3 together with bolts, and finally turn down the electrical appliance cover, and the The rear end is screwed on the electrical box 3 by bolts to complete the preliminary assembly of a single LED street lamp.
