Explosion-proof, short-circuit-proof and stroboflash-free high-voltage lamp strip driving control circuit

Abstract

The invention discloses an explosion-proof, short-circuit-proof and stroboflash-free high-voltage lamp strip driving control circuit, which comprises a power supply input end J1, a master control chipJ2, a power supply output end J3, a rectifier bridge D1, a control chip U1, a transformer T1, a protection chip U3, a protection chip U4, a field effect transistor Q1, a field effect transistor Q2, afield effect transistor Q4, a field effect transistor Q5, a diode D2, a diode D3, a diode D4, a diode D4, a diode D5, a diode D8, a diode D9, a diode D12, a diode D13, a diode D14, a diode D15, a diode D17, a polar capacitor C2, a polar capacitor C3 and a polar capacitor C6. According to the invention, the output frequency is high, so that a lamp is not stroboscopic; a circuit is cut off in timewhen a current is too large or short-circuited, so that the explosion-proof and short-circuit-proof effects are achieved; and the output voltage is stable, so that the explosion-proof, short-circuit-proof and stroboflash-free high-voltage lamp strip driving control circuit is suitable for different lamp strip using requirements.

Description

technical field [0001] The invention relates to a control circuit, in particular to an explosion-proof, short-circuit-proof, and flicker-free high-voltage strip drive control circuit. Background technique [0002] The existing high-voltage light belt drive power supply and high-voltage light belt plug products on the market generally have the following shortcomings: 1. There is stroboscopic flicker when turning on the light. Working or living under the light generated by the high-voltage light belt of this product directly leads People's vision declines and affects their health. 2. The power supply has no explosion-proof and short-circuit-proof functions, so that when users use this type of product, they will be directly injured by electric shock and personal safety, and during long-term use, this type of product will generate high temperature, causing short circuit of the product and prone to fire. 3. The dedicated power supply matches the dedicated light strip, resulting ...

[0002] The existing high-voltage light belt drive power supply and high-voltage light belt plug products on the market generally have the following shortcomings: 1. There is stroboscopic flicker when turning on the light. Working or living under the light generated by the high-voltage light belt of this product directly leads People's vision declines, affecting physical health

2. The power supply has no explosion-proof and short-circuit-proof functions, causing users to be directly injured by electric shock and personal safety when using this type of product, and during long-term use, this type of product will generate high temperature, causing short-circuit of the product and prone to fire

3. The special power supply matches the special light strip, which leads to poor applicability of the product during use, which is not conducive to user update and use
