The outdoor roads on the market at present have complex structures, poor sealing, and poor waterproof performance. After encountering rain, water is easy to enter, causing water to evaporate into water vapor in the lamp by heat, affecting the brightness and aesthetics of the lamp, and even causing circuit short circuits and fire accidents. In addition, the street lamp structure design of the prior art is unreasonable, the irradiation range is narrow, and a street lamp needs to be installed for a short distance, which is costly. Therefore, it is necessary to design a street lamp with reasonable structure, energy saving and environmental protection, good waterproof performance and wider illumination range on the basis of the existing design.

[0003] An environmentally friendly waterproof LED street lamp with publication number CN101907253B comprises: a lamp module, end caps installed at both ends of the lamp module and end caps with hollow round handles, the lamp module comprises two symmetrically structured first light-emitting units and a second light-emitting unit located between the two first light-emitting units, the two first light-emitting units and the middle second light-emitting unit are connected by a connecting shell, the angle between the two symmetrically structured first light-emitting units is 100 to 150 degrees, the first light-emitting unit comprises a main shell, an aluminum substrate fixed in the main shell, an LED lamp chip welded on the aluminum substrate, a reflector covering the LED lamp chip, glass located on the reflector, and the second light-emitting unit is located in a groove of the connecting shell.

[0007] Compared with the prior art, the present application adopts a dual structure to fully set the lamp assembly inside the mounting cover and the inner frame assembly, and completes the connection and fixation between the components through two detachable connection methods. At the same time, the sealing gasket structure is adopted to fully realize the sealing operation, effectively improve the waterproof characteristics of the lamp assembly, avoid water seepage, ensure that the lamp assembly can operate in the outdoor environment, and avoid water ingress affecting the lighting.

During preparation, the pressure ring and the top ring are both arranged in a ring shape, which can effectively seal and avoid penetration and leakage. That is, when water vapor enters through the screw groove, the water vapor will be sealed in the inclined opening, ensuring the dryness of the lamp assembly and preventing water vapor from entering.
