Abstract
The utility model discloses an over-current protective device for a light-emitting diode (LED) lamp. The over-current protective device consists of the following components: an LED lamp bulb, a current stabilizing module, a first line and a second line, and is characterized in that the second line is connected with the current stabilizing module, and an output terminal of the current stabilizing module is connected with the LED lamp bulb by means of the first line. The over-current protective device for the LED lamp efficiently eliminates the influence of current instability on the service life of the LED lamp.
Description
Technical field
The utility model relates to a kind of car headlight device, is a kind of LED lamp overcurrent protective device concretely.
Background technology
Because of automobile under steam, inevitably to increase or reduce throttle, the voltage of generator also increases thereupon or reduces, electric current is excessive, and the LED lamp will be burnt.
Summary of the invention
The purpose of this utility model is to provide a kind of LED lamp overcurrent protective 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 lamp overcurrent protective device mainly is made up of LED bulb, current stabilization module, first circuit, second circuit.It is characterized in that second circuit is connected with the current stabilization module, current stabilization module output is connected with the LED bulb by first circuit.At first second circuit is connected with the bulb power end of former car, opens switch, switch conduction, the electric energy of storage battery arrives the current stabilization module through switch, behind current stabilization module current stabilization, current stabilization is transported to the LED bulb, and the LED bulb is lighted.
The beneficial effects of the utility model are to efficiently solve the too high influence to the LED lamp life-span of electric current.
