High-voltage constant current soft lamp strip

The utility model discloses a high-voltage constant current soft lamp strip. The high-voltage constant current soft lamp strip comprises a rectifier bridge Q, LED lamp modules and control modules. According to the high-voltage constant current soft lamp strip, technical innovation is realized according to defects of conventional high-voltage soft lamp strip products in the market, the circuit principle is redesigned, a constant current power supply mode is designed according to the characteristic of LEDs, and resistors are not needed to be employed for voltage dividing; in each control module, only a constant current control chip U, a small capacitance filtering C, a current setting resistor R are needed, the circuit structure is simple, temperature protection is provided, when the temperature rises to a certain extent, the chip can automatically reduce the current, continuous temperature rise is prevented, the LEDs are protected, dynamic adjustment enables the LEDs to always operate at an optimal current, light failure is reduced, the service lifetime is extended, and the product quality is improved.
