Embodiment 1
[0019] Such as figure 1 As shown, a high heat dissipation LED billboard with self-cleaning function includes a housing 1, an LED panel 2 and a controller 3 electrically connected to the LED panel 2 are installed in the housing 1, and one side of the housing 1 is opened. And a transparent protective plate 4 is installed, and a heat dissipation fin is also embedded in the housing 1, and the heat dissipation fin is close to the inner wall of the transparent protective plate 4, which can continuously reduce the temperature at the inner wall of the transparent protective plate 4, and prevent water from being caused by the temperature difference between the inside and outside. The fog condenses, and the upper end of the housing 1 is fixed with a driving box 5, which is made of heat-conducting material, and a horizontal rack 6 is arranged inside the driving box 5, and the rack 6 is connected to the inner side of the driving box 5 through the memory spring 13 The wall is fixedly conne...
Embodiment 2
[0025] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the dust removal brush 14 is composed of a dust removal roller 18 and a brushing layer 19 sleeved outside the dust removal roller 18, and the brushing layer 19 can rotate freely around the dust removal roller 18, and the dust removal roller Both ends of 18 are fixed with cable 15, and fins 20 are installed at the two ends of brushing layer 19.
[0026] In this embodiment, the hot air in the casing 1 is exhausted from the exhaust pipe 17, and the airflow flows through the fins 20, driving the scrubbing layer 19 to rotate, further improving the cleaning effect on the transparent protective plate 4.
