Rotating rgb full color led display

Abstract

The rotating RGB full-color LED display screen of the present invention includes a base, the base includes a support plate and support legs, the upper surface of the support plate is fixed with a motor through a bracket, the outside of the motor is wound with a primary coil, and the rotating shaft of the motor is fixed to the bottom of the PCB board. On the surface, a sleeve is arranged outside the rotating shaft of the motor, and a secondary coil is wound on the outside of the sleeve, and the secondary coil provides power supply for the PCB board; the upper surface of the PCB board is welded with a main control chip, a driver chip and a display screen, The display screen includes three rows of parallel red LEDs, green LEDs, and blue LEDs. Each LED light is connected to a driver chip through a protection resistor, and each driver chip is connected to the main control chip respectively. The PCB board One end is welded with a zero-crossing detection circuit, and the zero-crossing detection circuit is connected with the main control chip. The invention has the advantages of simple structure, convenient use, low cost and low power consumption, and can form better image effects.

Description

technical field [0001] The invention relates to the field of LED lamp control design, in particular to a rotating RGB full-color LED display screen. Background technique [0002] Nowadays, various display screens are erected in the streets and alleys to attract the attention of pedestrians, but there are some shortcomings in the current small display screens. [0003] The existing small LED full-color display screens all appear in people's eyes in the form of a dot matrix, and its cost is not low, and its power consumption is also relatively large. [0004] The existing rotating POV designs are all related products made of monochrome LEDs, the colors are not bright enough, and they also need battery power, which is harmful to the environment, and a large part of the existing products use brushes. Power supply will not only cause great wear and tear, but also cause a lot of waste of electric energy, because a lot of heat energy will be generated during the friction process, ...
