LED car headlights work by utilizing light-emitting diodes (LEDs) to produce a bright and efficient beam of light. Here's how they work:

An electrical current is applied to the LED chip, which is made up of semiconductor materials that emit light when a current is passed through them.

The LED chip is then placed in a reflector or lens that directs the light into a focused beam.

A driver module is used to regulate the voltage and current supplied to the LEDs, ensuring they operate at the correct intensity and temperature.

The headlights are typically arranged in an array of several small LED bulbs, which allows for more precise control over the direction and focus of the light.

LED headlights are designed to be energy-efficient, with lower power consumption than traditional halogen headlights, while still providing a brighter and more focused beam of light.

LED headlights are also long-lasting and durable, with a lifespan of up to 20,000 hours or more, compared to around 1,000 hours for halogen headlights.

Overall, LED car headlights provide a brighter and more efficient source of light compared to traditional halogen headlights, while also being energy-efficient, long-lasting, and durable.
