LED street lamp

Abstract

The invention relates to an LED street lamp which comprises a lamp shell and a cover plate arranged at the lower portion of the lamp shell. The cover plate is composed of a plurality of branch cover plate bodies. The edges of the two sides of each branch cover plate body are provided with connecting holes, wherein the branch cover plate bodies are connected to the lamp shell through the connecting holes. The LED street lamp has the advantages that the cover plate is separated into a multi-block type, the weight is light, the strength is high, and the LED street lamp is not prone to deformation; due to the fact that a simple heat dissipation groove is formed in the cover plate, heat dissipation is smooth; the edge used for being inserted into a lamp outer frame or being compressed by a bolt is reserved on the cover plate, the cover plate can be conveniently assembled on the lamp outer frame, and convenience and flexibility are achieved; the lamp is rapid and convenient to maintain, and if something is wrong on a certain module, the module can be maintained or taken down to be replaced only by pushing aside or disassembling the corresponding branch cover plate body; the separated-type cover plate is small in required mold, and cost is reduced on the basis that the quality is improved.

Description

technical field [0001] The invention relates to an LED street lamp. Background technique [0002] The current LED street lamp modules are generally divided into two situations, one is connected with the lamp body as a whole, and the other is that the lamp body and the upper cover are separated, but it is a whole cover; in this case, there will be three kinds of problems: 1.

Problems solved by technology

[0002] The current LED street lamp modules are generally divided into two situations, one is connected with the lamp body as a whole, and the other is that the lamp body and the upper cover are separated, but it is an integral cover; in this case, three problems will arise: 1. It is inconvenient to assemble the lamps. 2. It is inconvenient to maintain the lamps. 3. It is very troublesome to solve the heat dissipation. 4. It is not conducive to the reasonable cooperation between the power and the length of the lamps.

[0003] For the first case of "integrating with the lamp body", the module must be assembled together with the parts of the lamp, which is cumbersome and easy to damage the module and lens, affecting the quality of light and the appearance, and the lens has scratches to make it shine It cannot be emitted according to the designed direction and angle, resulting in unqualified lamps. Even if the assembly is successful, if there is a problem with the lamp module during use, the entire lamp housing must be disassembled for maintenance, which affects work efficiency and is very troublesome.

[0004] For the second case, 'the lamp body and the upper cover are separated, but it is an integral cover', it is more convenient to assemble the module, but because the overall cover is larger and the board is thinner, the deformation after assembly is large, and there are Large irregular gaps make it difficult for the lamps to achieve a qualified appearance and excellent quality, especially for LED lamps that need good heat dissipation conditions. In order to meet the heat dissipation conditions, it is necessary to add heat dissipation slots, which makes the thin plate more The strength of the cover plate decreases, and the deformation is serious. When the cover plate needs to be opened, it is often difficult to open it. If there are fewer openings, it will affect the heat dissipation and reduce the service life of the lamp; if you want to increase the power of the lamp, you must increase the power of the lamp. The length of the lamp must increase the cover plate, and the cover plate needs to be redone or molded again, so it is very unreasonable
