Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lighting equipment, in particular to an LED street lamp with variable projection angle. Background Art
[0002] With the improvement of people's living standards and the development of urban construction, there are more and more facilities in football fields, basketball courts, and outdoor public fitness areas. The lighting requirements for these special places are also getting higher and higher. However, the position of the irradiation center of the mainstream lighting fixtures used in these occasions is not adjustable. Therefore, the installation position requirements are high. Slight deviation will lead to uneven illuminance, and further will cause glare and heat dissipation problems, affecting the service life of the lighting fixtures. Summary of the Utility Model
[0003] Aiming at the above problems, the purpose of the utility model is to provide an LED street lamp with variable projection angle, which can adjust the illumination angle in multiple angles, make the illuminance more uniform, and the adjustment is more convenient.
[0004] To solve the above technical problems, the technical scheme adopted by the utility model is as follows: An LED street lamp with variable projection angle has a housing, an adjusting frame is installed on the housing, the housing can rotate relative to the adjusting frame, a plurality of lighting modules are arranged in the housing, the lighting modules are installed on the housing through a rotating shaft, and a plurality of adjusting holes are arranged on the side close to the housing. An adjusting bolt is arranged on the housing, and the adjusting bolt can be inserted into and fixed in the adjusting holes. In the above technical scheme, heat dissipation holes are arranged in the middle and on both sides of the housing, and an insect-proof filter screen is arranged inside the heat dissipation holes.
[0005] In the above technical scheme, one end of the rotating shaft is installed on the housing, and an adjusting knob is arranged at the end.
[0006] In the above technical scheme, a scale disk is arranged at the connection between the adjusting frame and the housing.
[0007] In the above technical scheme, six lighting modules are arranged in the housing, the lighting modules are arranged in a matrix and are installed on the side wall of the corresponding housing through a rotating shaft.
[0008] In the above technical scheme, four adjusting holes are arranged on the lighting module, and the adjusting holes are arranged in an arc shape.
[0009] In summary, the beneficial effects of adopting the technical scheme of the utility model compared with the traditional technical means are as follows: After the utility model is installed, the housing can be adjusted as a whole at a large angle through the adjusting frame, and each lighting module can be adjusted independently at a small angle through the adjusting bolt and the rotating shaft, so as to achieve the most uniform illuminance on the ground. The whole street lamp does not need to be disassembled during adjustment, which is more convenient. Brief Description of the Drawings
