[0002] Solar energy is widely used in various fields, and solar lighting systems are particularly common. However, traditional solar lamps have many problems: First, the position of the sun changes all the time, and the altitude and azimuth angles change constantly throughout the day. Fixed-angle solar panels are difficult to receive light efficiently. When the light is oblique in the morning and evening, a lot of light energy is wasted, and it is impossible to provide sufficient power for lamps and energy storage devices; second, the sun's trajectory varies greatly in different seasons, and fixed panels cannot adapt. The sun's altitude and azimuth are different in spring, summer, autumn and winter, and the collection efficiency is limited. In the long run, the power supply of lamps is unstable, and lamps in areas with insufficient light are prone to extinguishing due to insufficient power.

[0003] Therefore, the existing energy-saving solar lamps need to be further improved. Summary of the invention

[0004] The purpose of the present invention is to provide an energy-saving solar lamp and a control method, which can make the solar panel better align with the sun's position and increase the efficiency of energy reception.

Compared with traditional fixed-angle solar panels, the light energy collection efficiency is significantly improved. At the same time, the vertical adjustment achieved by the lifting ring assembly, the transmission gear assembly and the height adjustment structure allows the solar panel to adjust the tilt angle in real time according to the changes in the sun's altitude angle. From the lower angle at sunrise, to the almost direct sunlight at noon, and then to the gradually lower angle at sunset, the panel always maintains a nearly perpendicular posture to the light, ensuring that the sunlight can be incident vertically, reducing reflection losses, and further enhancing the efficiency of converting light energy into electrical energy, storing more power for the battery in the lighting fixture body, and ensuring stable and long-lasting lighting power supply. At the same time, the height adjustment structure can drive the solar panel to flip its angle during its rotation, imitating the trajectory of the sun rising in the east and setting in the west, ensuring that the solar panel is always facing the sun, and the lifting ring assembly and the synchronous adjustment ring cooperate so that the synchronous adjustment ring is not affected by the rotation angle and always ensures the meshing transmission of the transmission gear assembly.

[0030] The rotating assembly 2 in the lighting fixture body 1 is responsible for adjusting the horizontal position of the solar panel. The truncated cone rotating seat 201 serves as a basic support, on which the rotating truncated cone 202 is mounted and a circular groove 203 is provided at the bottom. The inner ring gear 204 on the inner wall of the circular groove 203 meshes with the driving gear 206 at the output end of the forward and reverse motor 205 in the truncated cone rotating seat 201. When the forward and reverse motor 205 is started, the driving gear 206 rotates and drives the inner ring gear 204 to rotate, thereby driving the rotating truncated cone 202 to perform a circular motion on the truncated cone rotating seat 201, so that the flip solar panel assembly 3 installed on the rotating truncated cone 202 can rotate 360 ​​degrees in the horizontal direction, track the east-west movement trajectory of the sun in real time, and ensure that the solar panel always faces the approximate direction of the sun during the rising and setting process.

[0031] Lifting ring assembly 4 linkage: The lifting ring assembly 4 includes a lifting ring body 401 sleeved on the outer circumferential wall of the rotating table 202, which is closely associated with the rotating assembly 2. During the rotation of the rotating assembly 2, the height adjustment structure 7 plays a key role. The ring member 701 is fixed to the lamp holder body 101, and the arc guide groove 702 thereon is movably interlaced with the guide shaft 703 on the outer wall of the outer adjustment ring 602. Since the arc guide groove 702 is U-shaped, when the rotating table 202 rotates, the guide shaft 703 slides in the arc guide groove 702, driving the outer adjustment ring 602 to change its height. The outer adjustment ring 602 uses the clamping rotation relationship between the limit ring 601 and the limit ring 601 on the outer circumferential wall of the lifting ring body 401 and its own annular limit groove 603, so that the lifting ring body 401 is lifted and lowered synchronously.

In this way, through this series of gear meshing transmission power, the lifting movement of lifting ring body 401 is converted into the angle tilt of solar panel 302 around flip mount 301, so that solar panel can accurately track the change of solar altitude angle in vertical direction, from the lower angle at sunrise to the highest angle at noon and then to the lower angle at sunset, so as to always maintain a good lighting angle.
