[0029] The working principle of the adjustable brightness LED advertising board device will be described below.

[0030] As Figures 1-5As shown, when placing the LED advertising board mechanism 1, the lifting slider 25 can be moved downward by sliding on the outer wall of the slide rod 24 in the storage column 22, and at the same time, the pull block 295 on the left side of the locking box 29 below the left end of the storage column 22 is pulled, and then the locking hole 251 below the left end of the inner wall of the storage column 22 is aligned with the docking hole 221 below the left end of the inner wall of the storage column 22. When the locking hole 251 below the left end of the lifting slider 25 is aligned with the docking hole 221 below the left end of the inner wall of the storage column 22, the pull block 295 can be released, and the elastic energy released by the compression spring 291 can make the pressing plate 292 drive the insertion rod 293 to pass through the docking hole 221 and be clamped and limited in the locking hole 251 below the left end of the lifting slider 25, so that the lifting slider 25 is fixed at the bottom of the inner cavity of the storage column 22, and the four extension ground contact plates 27 are clamped into the four clamping grooves 28 by the connecting plate 26. The bottom of the base plate 21 has a large stress area, so that the overall storage column 22 is placed more stably. When storage is performed, the lifting slider 25 is only slid upward until it abuts against the top of the inner wall of the storage column 22, and the pull block 295 is pulled and released according to the same principle. The pressing plate 292 drives the insertion rod 293 to pass through the docking hole 221 and be clamped and limited in the locking hole 251 above the left end of the lifting slider 25, so that the four extension ground contact plates 27 are lifted, the storage space of the base plate 21 is reduced, and the LED light bar 111 in the inner cavity of the overall advertising board box body 11 is powered and lit by the LED light bar power supply 13 connected by an external wire. At the same time, the input current effective value of the light source can be changed by using the dimmer 14 to achieve the purpose of dimming. When the LED light bar 111 emits light, the advertising content on the advertising content paper 115 can be displayed by emitting light, so that the content on the advertising content paper 115 can be observed through the protective glass plate 114. When the LED light bar 111 is working, the cooling fan 151 in the inner cavity of the heat dissipation box 15 is also started. After the external air is filtered by the filter screen 152, it is uniformly blown into the inner cavity of the advertising board box body 11 through the air deflector 113 on the inner wall of the air inlet 112. The heat emitted by the LED light bar 111 is blown upward, so that it is blown out through the bottom of the vertical position of the rear side of the door-shaped air outlet duct 16, and the heat dissipation effect is achieved. The door-shaped air outlet duct 16 can prevent dust and foreign matter from falling into the inner cavity of the advertising board box body 11.
