Abstract

The invention discloses an LED lamp used on an LED display screen. A second bearing and a first bearing are installed on the side walls of the left side and the right side in an LED unit correspondingly. A fixed shaft is fixed in the LED unit through the first bearing and the second bearing; a second bevel gear is mounted on the rotating shaft at one end of the fixed shaft; a motor is installed above the second bevel gear, a first bevel gear is arranged on the surface of a rotating shaft of the motor, the first bevel gear is meshed with the second bevel gear, and openings are formed in the twosides of the LED unit, wherein a movable plate is installed on the surface of one opening, and one end of the movable plate is hinged to the opening of the LED unit through a hinge. The problem thatan LED lamp or a PCB is damaged due to the fact that an existing LED display screen is poor in waterproof and dustproof effect can be solved, the problem that the LED lamp is damaged and difficult toreplace can also be solved, and meanwhile, the problem that normal use of the LED display screen is affected due to the fact that the LED lamp is damaged can be solved.

Description

technical field [0001] The invention relates to the field of LED display devices, in particular to an LED lamp used on an LED display. Background technique [0002] At present, LED display modules on the market are generally poor in waterproof effect, and are easily corroded by rain or dust in bad weather such as rain, snow, and wind, resulting in large-scale damage to the LED lights inside the LED display module or damage to the PCB board. In the case of the LED display, the LED lights inside the LED display module are damaged due to various factors during the use of the LED display. However, due to the limitation of the structure of the LED display itself on the market, it will be difficult to replace the LED lights. Conditions that affect the normal operation of the LED display. [0003] Publication number: CN206363711U, discloses a LED display screen, which cannot solve the above-mentioned poor waterproof effect of LED display modules in the market, and is easily corrod...
