However, most high-voltage lamp belts in the current market only use the traditional simple power supply mode, and only use a bridge stack or a diode to perform full-bridge rectification on the mains supply to obtain a direct current and then directly supply power to the lamp belts; for some high-end double-color high-voltage LED lamp belts, only a plurality of fixed light modes are provided, and only the light modes can be switched in sequence, the mode sequence is fixed, free control cannot be realized, and intelligent control cannot be further realized; common RGB controllers in the market have complex circuit structure, high cost and poor stability, and are not beneficial to popularization and use in popular occasions; there are some theoretically more complicated controllers, which are complicated in that not only the switching power supply, the detection circuit, the dedicated chip, etc. are required, but also the CPU, etc. is required to participate in control and logic judgment.
If with the polychrome lamp area of current polychrome lamp area or attached control and the polychrome LED lamp area of driver, directly control at the high-pressure side, carry out the control in corresponding colour LED lamp area through the mode of simple control commercial power phase line promptly to realize traditional, simple, reliable control and mode of connection, go unlawful, light then can not normally work, if unusual scintillation, noise etc. then have heavy potential safety hazards such as burn out, commercial power short circuit, will cause serious consequence.
In summary, the conventional high-voltage LED multi-color lamp strip controller has a simple and fixed mode and cannot be freely selected and controlled; or the volume is large, the circuit and the structure are complex, the power consumption is large, the cost is high, and the device is not suitable for mass production and use with low cost and popularization; more importantly, the mode selection and control can not be simply and freely carried out on the high-voltage side, and the development and the application of the high-voltage LED multi-color lamp strip controller are limited to a certain extent. Therefore, the prior art needs to be improved and improved, control is only performed at the high-voltage end, simple and reliable free control and intelligent control are realized, the complexity of a circuit and a structure and the cost of a product are reduced, and mass production and use can be performed.
