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.

Abstract

The invention belongs to the field of LED lamps, and in particular relates to a high heat dissipation LED billboard with a self-cleaning function, which includes a housing in which an LED panel and a controller electrically connected to the LED panel are installed. One side of the opening is provided with a transparent protective plate, the upper end of the housing is fixedly installed with a drive box, the drive box is provided with a horizontal rack, and the rack is fixed to the inner wall of the drive box by a memory spring connected, the inner bottom surface of the drive box is rotatably connected with a tooth column, the tooth column meshes with the rack, and a ventilation box is fixed above the drive box, and the ventilation box communicates with the housing through a ventilation tube. There is a rotating shaft rotating horizontally inside the ventilation box, and an exhaust fan and a crown gear are coaxially fixedly installed outside the rotating shaft, and the crown gear meshes with the tooth column. The invention can spray relatively hot air in the casing to the surface of the transparent protective plate, and condense water droplets when it encounters condensation, thereby facilitating the cleaning and maintenance of the transparent protective plate while achieving a good heat dissipation effect.

Description

technical field [0001] The invention belongs to the field of LED lamps, in particular to a high heat dissipation LED billboard with self-cleaning function. Background technique [0002] LED advertising is a form of new media advertising, which is a perfect combination of new media technology and outdoor advertising. It controls the display mode of semiconductor light-emitting diodes to display text and images on the display screen. [0003] Most of the current outdoor LED billboards are embedded in the shell, which is not conducive to heat dissipation. Most of the outdoor LED billboards work continuously throughout the day, and their internal temperature is high, which is easy to accelerate the aging or even damage of internal electrical components. If it is outside for a long time, dust will accumulate on the screen, which will affect the viewing and publicity effect. Since LED billboards are mostly set at higher positions to facilitate pedestrians to observe, it is very tr...
