Embodiment Construction

[0010] Depend on figure 1 , 2 Known, a turn signal LED module alarm module, is made up of circuit board 1, LED circuit board 2; LED particle 11 and resistor 12 are arranged on LED circuit board 2; MOS tube 24, power resistor 25 are installed on circuit board 1 , a single chip microcomputer 23, a drive control IC 22, and a current detection resistor 21; the circuit board 1 and the LED circuit board 2 are connected by wires. The LED particles 11 are powered by the drive control IC22, so that the current of each LED particle 11 is controlled at 150ma0.5W, and the current of 7 LED particles is about 3.5W. The current detection resistor and the single-chip microcomputer monitor the LED working status in real time. W, so that the power reaches 21W; when two or more LEDs are damaged, the single-chip microcomputer detects the failure of the LED module, turns off the drive output so that the current of the whole lamp is basically zero, and the flasher of the whole vehicle flashes quic...

Abstract

A steering lamp LED module alarm module is composed of a circuit board (1) and an LED circuit board (2). The LED circuit board (2) is provided with LED particles (11) and resistors (12). The steering lamp LED module alarm module is characterized in that the LED particles (11) are powered up by a drive control IC (22), the LED particles (11) are monitored in real time by a current detection resistor (21) and a single chip microcomputer (23), the current of each LED is controlled to be 150 ma 0.5 W, an MOS transistor (24) and a power resistor (25) constitute additional power, and accordingly the output power reaches 21 W. By means of the steering lamp LED module alarm module, the problem that the power of a steering lamp LED module is not matched with the power of a halogen lamp light source is solved, LED module faults can be detected, the current of an entire lamp is basically made to be zero when drive output is closed, and a Flasher of an entire vehicle flashes quickly and gives an alarm.

Description

technical field [0001] The invention relates to the industry of automobile lamps, in particular to an energy-consuming module of an LED module of a turn signal for an automobile headlamp. Background technique [0002] At present, LED is widely used as the light source in the headlights of new cars. At the same time, many lamps of old models have been upgraded, and the original halogen light source has been changed to LED light source. Turning halogen light sources are generally 12V21W, and general LED modules are 12V6~8W, resulting in a mismatch between the power of the turn signal LED module and the power of the halogen light source. When the LED module fails due to low power, the flashing alarm on the vehicle Unable to perceive and alarm. Contents of the invention [0003] In view of the above-mentioned defects, the object of the present invention is to provide a turn signal LED module alarm module, by adding a MOS tube and a power resistor on the circuit board, the pow...
