Multicolor high-voltage lamp strip control and drive device for high-voltage end control

Abstract

The invention belongs to the field of high-voltage lamp strip control and drive, and particularly relates to a multicolor high-voltage lamp strip control and drive device for high-voltage end control.The multicolor high-voltage lamp strip control and drive device comprises a commercial power input and control module (A), a surge protection module (B), an EMC protection module (C), a mode indication module (D), a high-voltage detection module (E), a full-bridge rectification module (F), an output selection control module (G), an output detection and protection module (H) and a lamp strip output module (I). The on-off (brightness and the like) of lamp strips with corresponding colors is controlled by directly controlling the on-off (phase and the like) of a 220V or 110V mains supply phase line, so that free selection and intelligent control of light modes are realized.

Description

technical field [0001] The invention belongs to the field of high-voltage lamp strip control and drive, and in particular relates to a multi-color high-voltage lamp strip control and driver for high-voltage end control. Background technique [0002] With the continuous improvement of the quality of life and the reduction of the cost of LED lamp beads, the demand for LED light strips is also increasing. LED light strips are often used to outline the outlines of various buildings, build large-scale lighting patterns, and various residential and indoor lighting decoration occasions, which have attracted much attention and favor from people. At present, there are several series of high and low voltage LED strips such as single-color LED strips, two-color LED strips and RGB strips on the market. [0003] High-voltage LED strips are more and more popular because they are easy to install, can be directly driven by a high-voltage driver, and can work normally after being connected ...

AI Technical Summary

Problems solved by technology

However, most of the high-voltage light strips currently on the market just follow the traditional simple power supply method, only using bridge stacks or diodes to perform a full-bridge rectification of the mains, and directly supply power to the light strips after obtaining a DC power; for some high-end two-color high-voltage LED lights There are only a certain number of fixed lighting modes, and the lighting modes can only be switched in order. The order of the modes is fixed, and it cannot be controlled freely, let alone intelligently controlled; common RGB controllers on the market have complex circuit structures, high costs, and stability. poor performance, which is not conducive to popularization and use in popular occasions; there are also some theoretically more complex controllers, which not only need switching power supply, detection circuit, special chip, etc., but also need processors such as CPU to participate in control and logic judgment, and even is complicated

[0004] If the existing multi-color light strip or multi-color LED light strip with control and driver is directly controlled on the high-voltage side, that is, the corresponding color LED light strip is controlled by simply controlling the mains phase line, thereby realizing the traditional Simple, simple and reliable control and wiring methods will not work, ranging from abnormal work, such as abnormal flickering, noise, etc., to serious safety hazards such as burning, short circuit of mains power, etc., which will cause serious consequences

[0005] To sum up, the current high-voltage LED multi-color light strip controllers are either simple and fixed in mode and cannot be freely selected and controlled; or they are bulky, complex in circuit and structure, high in power consumption, and high in cost, which is not suitable for low-cost, popular Mass production and use; more importantly, the simple and free selection mode and control cannot be performed on the high-voltage side, which limits the development and application of high-voltage LED multi-color light belt controllers to a certain extent
