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 A transparent protective plate 4 is installed, and heat dissipation fins are embedded in the housing 1. The heat dissipation fins are close to the inner wall of the transparent protective plate 4, which can continuously reduce the temperature of the inner wall of the transparent protective plate 4 to prevent water caused by the temperature difference between the inside and the outside. When the fog condenses, a drive box 5 is fixedly installed on the upper end of the housing 1. The drive box 5 is made of heat-conducting material. The drive box 5 is equipped with a rack 6 arranged horizontally. The rack 6 is connected to the inner side of the drive box 5 through a memory spring 13 The wall is fixedly connected, the...

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 scrubbing layer 19 sheathed outside the dust removal roller 18. The scrubbing layer 19 can rotate freely around the dust removal roller 18. Both ends of 18 are fixed to the cable 15, and fins 20 are installed at both ends of the scrubbing layer 19.

[0026] In this embodiment, the hot air in the casing 1 is discharged from the exhaust pipe 11, and the airflow flows through the fins 20, which drives the scrubbing layer 19 to rotate, which further improves the cleaning effect of the transparent protective plate 4.

Abstract

The invention belongs to the field of LED lamps, particularly to a high-heat-dissipation LED advertising board with a self-cleaning function. The advertising board comprises a shell, wherein an LED panel and a controller electrically connected with the LED panel are installed in the shell; an opening is formed in one side of the shell, and a transparent protective plate is mounted at the opening;a driving box is fixedly mounted at the upper end of the shell; a rack which is horizontally arranged is arranged in the driving box; the rack is fixedly connected with the inner side wall of the driving box through a memory spring; a toothed column is rotatably connected to the inner bottom surface of the driving box and is engaged with the rack; an air exchange box is fixed above the driving box; the air exchange box communicates with the shell through an air exchange pipe; a rotating shaft horizontally rotates in the air exchange box; an exhaust fan and a crown gear are coaxially and fixedly installed outside the rotating shaft; and the crown gear is engaged with the toothed column. Hot air in the shell can be sprayed to the surface of the transparent protection plate, and water drops are condensed when the hot air is in a cold environment, so a good heat dissipation effect is achieved, and cleaning and maintenance of the transparent protective plate are facilitated.

Description

Technical field [0001] 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. Background technique [0002] LED advertising is a new media advertising form, which is a perfect combination of new media technology and outdoor advertising release form. It controls the display mode of semiconductor light-emitting diodes to display text and video display screens. [0003] The current outdoor LED billboards are mostly embedded in the shell, which is not conducive to heat dissipation. Most of the outdoor LED billboards work uninterruptedly throughout the day. The internal temperature is high, which is easy to accelerate the aging or even damage of internal electrical components. If you stay outdoors for a long time, dust will accumulate on the screen, which will affect the viewing and publicity effects. However, because LED billboards are mostly set up at a higher position to facilitate pedestrian ...
