Angle-adjustable LED street lamp

Abstract

The invention discloses an angle-adjustable LED street lamp. The angle-adjustable LED street lamp comprises a lamp handle, a lamp body and a connecting joint, wherein the connecting joint is fixedly connected with the lamp body, one end of the lamp handle is used for being connected with a lamp pole of the street lamp, the other end of the lamp handle is fixedly connected with the connecting joint, the lamp body, the connecting joint and the lamp handle are separately arranged, parts are reasonably partitioned, the structure of the lamp body and the structures of the parts are all simplified, and the situation that sectional materials are adopted for manufacturing is made possible. The connecting joint comprises a shaft outer ring and a center shaft penetrating through the shaft outer ring, the contact area of the center shaft of the connecting structure and the shaft outer ring is large, when the angle is adjusted, stress can be shared by a large area, and breakage caused by overlarge stress is not likely to happen. The shaft outer ring is fixedly connected to the lamp handle, the center shaft is fixedly connected with the lamp body, the center shaft and the shaft outer ring can be rotationally connected, and a positioning mechanism capable of controlling the relative rotating angles of the center shaft and the shaft outer ring is arranged between the center shaft and the shaft outer ring. Because the contact area of the shaft outer ring and the center shaft is large, the positioning mechanism also has a large contact area, stress is shared when applied, and damage is not likely to happen.

Description

technical field [0001] The application belongs to the field of lighting equipment, in particular to an angle-adjustable LED street lamp. Background technique [0002] LED, or light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light, and is widely used because of its energy saving, longevity, environmental protection, and easy installation. Based on the above characteristics, LEDs continue to replace traditional light bulbs and become an emerging lighting medium. [0003] The lamp body of the traditional LED lamp is fixed by connecting the joint and the lamp handle. In order to adapt to the use requirements in different situations, the angle of the lamp body to the ground sometimes needs to be preset according to different situations to ensure a better lighting effect, but This requires pre-adjusting the angle of the lamp body each time. Subsequently, people design the s...

Problems solved by technology

[0004] However, the rotatable LED lights in the prior art have the following problems: (1) In order to make an adjustable angle structure, the structure of the lamp body and the connecting joint is complicated and the shape is special, so the mold must be opened and cast, and all of them cannot be made of profiles. (2) Due to the complex structure and many parts, the assembly is difficult, the production efficiency is reduced, the cost is high, and the positioning is not accurate, which is not conducive to the promotion and application of LED street lights with adjustable angles.
