Abstract

The invention, which relates to the technical field of the LED illumination, provides an LED lamp circuit comprising a current-limiting resistor, a capacitor, an anti-reverse-connection circuit, and aplurality of LED beads. The anti-reverse-connection circuit is composed of a comparator, a triode and a relay; the triode is arranged between the comparator and the relay; the comparator is connectedto the capacitor; the relay is arranged at the input terminal of an external power source; and the plurality of LED beads are arranged between the relay and the multiple LED beads. The LED lamp circuit has advantages of simple structure and low cost. With the current-limiting resistor arranged in the LED lamp circuit, the working current is limited by the resistor and the current can be controlled, so that the service life of the product is prolonged effectively; and with the anti-reverse-connection circuit, burning of the elements and light source caused by manual reverse polarity connectionduring the installation and maintenance processes can be prevented.

Description

technical field [0001] This application relates to the technical field of LED lighting, in particular to an LED lamp circuit. Background technique [0002] With the development of the economy and the progress of the society, energy conservation has become a social consensus and an inevitable development. LED lamps are an energy-saving and environmentally friendly green product, and are currently developing more and more rapidly in the lighting industry. Since LED is a sensitive semiconductor device with negative temperature characteristics, it needs to keep its working state stable during the application process. Unlike ordinary incandescent bulbs, LED can be directly connected to AC mains. LED is 2-3V For low-voltage driving, it is necessary to design a circuit that meets the requirements to drive it to work normally. At present, LED lights are usually made of several LED lamp beads in series. Due to the discreteness of LED lamp beads, if constant current drive is not used,...
