High-voltage three-color LED horse race lamp belt

Abstract

The invention discloses a high-voltage three-color LED horse race lamp belt which comprises a double-faced flexible belt-shaped circuit board. The circuit board is welded with three pieces of LED paster with different light-emitting colors, and a printed conductor and a printed power source wire are arranged. The lamp belt further comprises an LED control module which is connected with the power source wire. The three pieces of LED paster with the different light-emitting colors respectively refer to the LED paster I, the LED paster II and the LED paster III. The power source wire comprises a public live wire and three null lines which refer to the null line I, the null line II and the null line III, wherein the null line I, the null line II and the null line III are used for controlling the LED paster I, the LED paster II and the LED paster III respectively. The null line I, the null line II and the null line III are connected to signal output ends of the LED control module respectively. According to the high-voltage three-color LED horse lamp belt, low electrical levels are sequentially output to the null line I, the null line II and the null line III through the LED control module, the LED paster of different colors on each light-emitting unit is controlled to be sequentially lightened and extinguished, and the light-emitting effect of a color intrigue horse race lamp is achieved.

Description

technical field [0001] The invention relates to an LED light strip, in particular to a high-voltage three-color LED marquee light strip. Background technique [0002] Existing high-voltage LED marquee strips are usually composed of three LEDs R (red), G (green), and B (blue) and corresponding control ICs welded on a circuit board. The whole light strip is divided into several loops, one loop contains 3 LED lamp beads and one IC, the LED circuit can be controlled through the LED control module to control the IC, so as to control the luminous effect of the LED light strip. The disadvantage of the existing light strips is that multiple control ICs need to be welded on the circuit board on which the LED lamp beads are welded, resulting in a cumbersome welding process. In addition, the power lines of traditional high-voltage LED marquee strips are generally buried on the core strip, which is easily exposed and penetrates the insulating sleeve, causing electric shock accidents. ...
