Embodiment 1
[0023] Such as Figure 1~3 As shown, a high-efficiency LED solar street lamp includes a vertically arranged light pole 2, an LED lamp 1 is arranged on the light pole 2, and a side bracket 4 is also arranged on the light pole 2, extending outward along the side bracket 4 A plurality of solar panels 5 are distributed in parallel in the direction. In this embodiment, the side bracket 4 and the light pole 4 are vertical and horizontal to the ground; the lower end of the solar panel 5 is hinged on the side bracket 4 in the horizontal direction. The upper end of the panel 5 is hinged on an upper support rod 7 in the horizontal direction, and the upper support rod 7 and the side support 4 are arranged in parallel; the upper support rod 7, the solar panel 5, the side support 4 A parallelogram structure is formed through a hinged relationship; a power device for fixing and pushing the upper support rod 7 to move up and down is also arranged. The power device in this embodiment is an el...
Embodiment 2
[0025] exist image 3 In this case, the angle between the sunlight incidence angle and the light pole is small, in this case, the previous solar panel 5 will not block the light of the rear solar panel 5; figure 2 Among them, the previous solar panel 5 is in the critical position of blocking the light of the rear solar panel 5 . if figure 2 The incident angle of the medium ray is the maximum value of the incident angle of sunlight in a day in a certain area. Then the solar panels 5 of the solar street light are arranged in parallel, and the vertical distance between two solar panels 5 is set as L, and the distance L should be the length in the figure. Even when sunlight is irradiated at the maximum angle in a day, the preceding solar panel 5 will not block the light of the latter solar panel 5 .
Embodiment 3
[0027] This embodiment further explains that the rotating mechanism of the above-mentioned embodiment 1 includes a motor located on the light pole 2, and a gear driven by the motor, the gear is located inside the light pole 2, and the sleeve 3 The inner wall of the inner wall is provided with inner teeth meshing with the gear. Driven by the motor, the gear meshes with the teeth provided on the inner wall of the sleeve 3, so that the sleeve 3 can be driven to rotate around the light pole 2.
