Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, and in particular to a dual-cavity linked LED street light. Background Technology

[0002] like Figure 7 As shown, the back cover structure of traditional LED streetlights is fixed with bolts. The back cover is fixed to the lamp body around its perimeter with bolts. However, this structure has many problems.

[0003] On the one hand, the integrated bolt-fixed structure requires tools to remove all bolts during installation and maintenance, which is very inconvenient. On the other hand, the back cover of the light source cavity and the back cover of the power supply cavity are independent of each other, but in actual operation, the back covers of the light source cavity and the power supply cavity cannot be opened simultaneously. Operators often try to save time by opening the light source cavity separately, and may cause electric shock due to misoperation without understanding the circuit layout, which poses a great safety hazard. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a lamp with a glass-hole-free rotating device, which makes opening and closing easier and subsequent maintenance more convenient.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a dual-cavity linked LED street light, comprising a lamp body, wherein the lamp body is provided with an independent electrical cavity and a light source cavity, the electrical cavity is provided with an electrical cavity rear cover, the electrical cavity rear cover is hinged to one end of the lamp body, the light source cavity is provided with a light source cavity rear cover, the light source cavity rear cover is hinged to the other end of the lamp body, the electrical cavity rear cover and the light source cavity rear cover open towards each other, and the electrical cavity rear cover presses on the light source cavity rear cover, the electrical cavity rear cover is provided with a buckle, the buckle can be fixed in the buckle groove of the lamp body, and one end of the electrical cavity rear cover presses on the light source cavity rear cover.

[0006] In the above technical solution, a partition is provided between the electrical cavity and the light source cavity, and the fastener groove is located on one side of the partition.

[0007] In the above technical solution, the sealing device is a sealing ring, a sealing ring seat is provided on the partition plate inside the electrical cavity, the sealing ring is installed on the sealing ring seat, and the rear cover of the electrical cavity can be closed on the sealing ring seat.

[0008] In the above technical solution, multiple heat dissipation holes are symmetrically arranged on both sides of the back cover of the light source cavity.

[0009] In the above technical solution, the rear cover of the electrical cavity is hinged to one end of the lamp body via a rotating shaft seat and its rotating shaft, and the rear cover of the light source cavity is hinged to the other end of the lamp body via a hinge.

[0010] In the above technical solution, a sealing device is provided between the rear cover of the electrical cavity and the electrical cavity.

[0011] In the above technical solution, a male and female connector is provided at the connection between the electrical cavity rear cover and the light source cavity rear cover, and the connector of the electrical cavity rear cover covers the connector of the light source cavity rear cover.

[0012] In summary, the advantages of using the technical solution of this utility model compared to traditional technical means are as follows:

[0013] This utility model divides the lamp body into an independent electrical cavity and a light source cavity. The rear cover of the electrical cavity and the rear cover of the light source cavity are hinged to the two respectively. The electrical cavity and the light source cavity can be opened by opening the fasteners used for fixing. The two rear covers can be opened very conveniently without tools. This makes the operation simple and convenient during installation and maintenance, and at the same time, it can meet the usage requirements of sealing the electrical cavity and ventilating the light source cavity.

[0014] Furthermore, the two rear covers of this utility model adopt a linkage opening mechanism, with the electrical cavity rear cover pressing on the light source cavity rear cover. On the one hand, it is more convenient to open, and on the other hand, it ensures that when the light source cavity is opened, the power supply cavity is necessarily opened at the same time. This forces the operator to see and possibly disconnect the power supply connection in the power supply cavity before performing any operation in the light source cavity (such as changing lamps, cleaning, etc.), or at least be aware of the existence of the power supply. This greatly reduces the risk of electric shock due to forgetting to turn off the power, and greatly improves the safety of operation. Attached Figure Description
