What would be the most important part for the leds? Of course it will LED chips and circuit
An LED driver circuit and method are disclosed where an array of light emitting diodes have a transistor connected to each respective array of light emitting diodes. A PWM controller has an input for receiving a voltage reference and an output connected to selected transistors for driving selected transistors and setting a PWM duty cycle for the selected arrays of light emitting diodes to determine the brightness of selected light emitting diodes. An oscillator is connected to the PWM controller for driving the PWM controller.Automobiles typically use standard bulbs in the stop-tail-turn combination lamps located at the rear of automobiles
The driver circuit is the key point for the IC driver ,which will affect the application for more cars and stable for the led lights.
