Abstract

The invention provides a high-voltage LED light belt. The high-voltage LED light belt comprises an electric connector and a light belt body; an LED circuit is arranged in the light belt body; a rectifier and filter circuit is arranged in the electric connector and comprises a rectifier bridge and a filter capacitor; and the input ends of the rectifier bridge are connected with a mains supply, the output end of the rectifier bridge is connected with the filter capacitor, and the two ends of the filter capacitor form the output ends of the rectifier and filter circuit to be connected with the LED circuit. The high-voltage LED light belt is characterized in that the rectifier and filter circuit further comprises an NTC thermistor, and one of the input ends of the rectifier bridge is connected with the mains supply through the NTC thermistor. When the high-voltage LED light belt is just connected with the mains supply, the resistance value of the NTC thermistor is large, the voltage between the two ends of the filter capacitor is small, and sparks are avoided; and after an electric current flows into the filter capacitor for a period of time, the temperature is raised, the resistance value of the NTC thermistor is decreased, the voltage between the two ends of the filter capacitor is increased, and the LED circuit works normally.

Description

technical field [0001] The invention relates to the lighting field, in particular to a high-voltage LED lamp strip. Background technique [0002] On January 18, 2017, the applicant submitted an invention patent application to the State Intellectual Property Office of China for "High-voltage LED strips that can effectively weaken the stroboscopic phenomenon". The patent application number is 201710039743.3. The stroboscopic phenomenon of the strip, but at the moment of contact when the plug of the strip is inserted into the socket, the current increases instantly due to the charging and discharging of the filter capacitor, which is easy to generate sparks and makes the user feel uncomfortable in the sense. improved. Contents of the invention [0003] The invention provides a high-voltage LED light strip, which is used to solve the problem in the prior art that sparks are easily generated at the instant when a plug of the light strip is inserted into a socket. [0004] Tec...
