The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.
[0016] like Figure 1-4 A solar street light with a heat dissipation function is shown, comprising a lamp body 1 and a heat dissipation component installed inside the lamp body 1, the lamp body 1 comprises a shell 2 and a control board, the control board is installed inside the shell 2, a solar cell is fixedly installed on the outer wall of the shell 2, the heat dissipation component comprises a cover plate 4 and an electromagnet 7, a heat dissipation port 6 is opened on the outer wall of the shell 2, the cover plate 4 is movably installed above the heat dissipation port 6, the electromagnet 7 is fixedly installed on the inner wall of the heat dissipation port 6, the electromagnet 7 is electrically connected to the control board, and a metal plate 10 is embedded and installed on the outer wall of the cover plate 4 facing the electromagnet 7, and the installation position of the metal plate 10 corresponds to the electromagnet 7.
[0017] A hole is opened at one end of the cover plate 4, a fixing rod is fixedly installed on the outer wall of the housing 2, and one end of the cover plate 4 is installed on the outside of the fixing rod through the opening, and the metal plate 10 is made of iron metal. Mounting holes are opened on both sides of the outer wall of the housing 2, and a heat sink 3 is embedded in the mounting holes. A fan 5 is installed inside the heat sink 3, and the fan 5 is connected to the control board. A plurality of slots are opened through the outer wall of the heat sink 3.
[0018] A support rod 8 is installed between the inner walls on both sides of the heat dissipation port 6, and both ends of the support rod 8 are rotatably connected to the inner wall of the heat dissipation port 6. The shape of the support rod 8 is Ω-shaped, and the support rod 8 is installed below the cover plate 4. A torsion spring 9 is sleeved and installed at the end of the support rod 8, and one end of the torsion spring 9 is fixedly connected to the inner wall of the heat dissipation port 6, and the other end is fixedly connected to the outer wall of the support rod 8.
[0019] Embodiment: The control panel inside the shell 2 controls the start and stop of the light source of the lamp body 1 and the internal temperature detection. When the temperature inside the shell 2 is high, the fan 5 will start, and the hot air inside the shell 2 will be discharged through the heat dissipation chamber 3 to cool the inside of the shell 2. In the initial state, the electromagnet 7 is in a normally open state, adsorbed with the metal plate 10 on the cover plate 4, and the support rod 8 is pressed down by the cover plate 4 inside the heat dissipation port 6. When the temperature inside the shell 2 is too high and the heat dissipation efficiency of the fan 5 is insufficient, the electromagnet 7 is powered off, the cover plate 4 and the electromagnet 7 are no longer adsorbed, the torsion spring 9 rotates the support rod 8 upward through torsion, and the support rod 8 flips the cover plate 4 upward, so that the heat dissipation port 6 is opened, and a large amount of external cold air enters the shell 2 to cool the shell 2. After the cooling is completed, the electromagnet 7 will be powered on again, and the metal plate 10 will be driven by the strong suction force of the electromagnet 7, and adsorbed with the electromagnet 7 again, pressing down the support rod 8, and closing the heat dissipation port 6.
