Embodiment 1
[0026] like Figure 1-4 As shown, a cooling and dust-removing LED street lamp based on the Bernoulli principle includes a lamp body, the lamp body includes a lamp cap 1 and a lamp cover 2, the interior of the lamp cap 1 is fixedly connected with an LED lamp tube 3, and the middle part of the bottom surface of the lamp cap 1 is arched upwards Setting, the peripheral side wall of lamp cover 2 is provided with a plurality of cooling holes 4, it is worth mentioning that, near the center of the upper side wall of lamp cap 1 is provided with a plurality of ventilation holes 14, and the upper side wall of lamp cap 1 is fixedly connected There is a shielding cap 15, which is arranged on the upper ends of a plurality of ventilation holes 14, and the shielding caps 15 can prevent dust and rainwater from entering the interior of the lamp body through the ventilation holes 14, and the upper end of the LED lamp tube 3 is provided with a cooling fan arranged horizontally 5. The cooling fan ...
Embodiment 2
[0037] like Figure 5-7 As shown, the difference between this embodiment and Embodiment 1 is that the upper end of the threaded rod 6 extends to the upper end of the lamp cap 1 and is fixedly connected with a ventilating plate 16, and the ventilating plate 16 is rotatably connected with the upper side wall of the lamp cap 1 and covers multiple The upper end of each vent hole 14, the vent plate 16 is provided with two arc-shaped communication openings 17 arranged symmetrically about the central axis of the vent plate 16.
[0038] In this embodiment, in the initial state, the air-permeable plate 16 will seal the air hole 14, such as Figure 6 As shown, it can effectively prevent dust from entering the interior of the lamp body through the vent hole 14. When the memory spring 8 or the wing plate 10 drives the threaded rod 6 to rotate, the breathable plate 16 fixedly connected to the upper end of the threaded rod 6 will follow the threaded rod 6 Rotating, the arc-shaped communica...
