Abstract
An LED reversal protector comprises a control module, a lamp socket and a diode. The control module and the diode are mounted in the lamp socket. The LED reversal protector is characterized in that a cathode of the diode is connected with the control module, an anode of the triode is connected with a negative pole, and the negative pole is riveted on the lamp socket. The LED reversal protector can effectively solve the problem that an LED lamp is burned due to reversed connection of a positive pole and the negative pole.
Description
Technical field
The utility model relates to a kind of car headlight device, is a kind of LED reverse protection device concretely.
Background technology
Because of the control of the switch of automobile has the anodal output of control and two kinds of patterns of negative loop, and the LED bulb has the differentiation both positive and negative polarity, and both positive and negative polarity connects instead might cause burning of bulb and chip.
Summary of the invention
The purpose of this utility model is to provide a kind of LED reverse protection device, makes guaranteeing the function of former automotive lighting, also has advantages such as little power consumption, bulb be not fragile.
The utility model is realized with following technical scheme: this a kind of LED reverse protection device critical piece is made up of control module, lamp socket, diode, and control module and diode are contained in the inside of lamp socket.It is characterized in that the negative electrode of diode is connected with control module, anode is connected with negative pole, and the negative pole riveting is on lamp socket.Diode is contained on the loop of negative pole, can guarantee effectively that power line connects instead, and anodal electric current can not enter control module by diode and arrive the LED bulb, thereby protection LED lamp and control module are not burnt.
The beneficial effects of the utility model are to have effective solution both positive and negative polarity and connect burning of opposition LED lamp.
