Description

Technical Field

[0001] The present invention relates to the technical field of high pole lamps, and more specifically, to an LED high pole lamp with adjustable illumination angle. Background Art

[0002] With the acceleration of urbanization and the continuous improvement of infrastructure construction, high pole lamps, as an important part of urban lighting, have an increasing market demand. Especially in some large public places such as stadiums and squares, high pole lamps have become an indispensable lighting equipment.

[0003] The illumination angle of the existing high pole lamp LED lamp head is fixed, and the pitch angle cannot be adjusted according to actual needs. This leads to unsatisfactory lighting effects in some application scenarios, such as the light is too concentrated or the illumination range is insufficient, which cannot meet the lighting needs of specific areas. The expansion range of the lamp arm of the existing high pole lamp is limited, and it cannot be flexibly adjusted according to the site and lighting needs. This limits the installation position and lighting range of the LED lamp head, affecting the lighting effect. In addition, the existing high pole lamp lacks a detection mechanism for the installation stability of the lamp unit. When the lamp unit fails, it is often impossible to detect and maintain it in time. This may lead to a decrease in lighting effects and even cause safety hazards. Summary of the invention

[0037] Working principle: The LED high pole lamp of the present application has multiple LED lamp heads, and the pitch illumination angles of the LED lamp heads and the expansion angles of the first and second rotating lamp arms can be adjusted, so as to achieve the adjustment of the illumination range. Specifically, the vertical slide can be translated by an electric telescopic rod, and as the vertical slide translates, the two U-shaped limit rods translate along, so that due to the cooperation between the U-shaped limit rod and the first strip through groove and the second strip through groove, the expansion angles of the first rotating lamp arm and the second rotating lamp arm can be adjusted. When the vertical slide translates in the direction away from the lamp pole, the expansion angles of the first and second rotating lamp arms become smaller, and because the connecting pull rope, the first pull rope and the second pull rope are shortened, the pulling force becomes smaller, so that under the action of the first spring, the front end of the LED lamp head rotates downward, so that the overall illumination range of the LED high pole lamp becomes smaller. When the vertical slide moves toward the direction close to the lamp pole, the expansion angles of the first and second rotating lamp arms increase, and since the connecting pull rope, the first pull rope and the second pull rope are stretched, the tension increases, so that the front end of the LED lamp head rotates upward, thereby increasing the overall illumination range of the LED high pole lamp.

[0038] The first and second detection plates can abut against the first pull rope and the second pull rope. Under normal circumstances, the measurement values ​​of the angle sensors corresponding to the four detection plates should be equal. When the measurement values ​​of the four angle sensors are inconsistent, it indicates that a fault has occurred, so that maintenance can be reminded in time. Therefore, the detection mechanism can detect the installation stability of the lamp unit.
