Future or LED headlights to indicate driving direction

LED technology has been widely used in automobiles, including daytime running lights, tail lights, and width lights. The illuminance of LED lights can meet the needs of current car safety. Behind the LED light technology is a complex electronic control strategy.

LED advantages

LED lights have many advantages over halogen and xenon lamps. Designers can use the LED light unit to lay out a more aesthetically pleasing design. In terms of luminous efficiency and safety, LED lights are also superior. The light emitted by the LED is closer to the wavelength of the sun. For other road users, the discomfort of the LED light is much less than that of halogen and xenon lamps. In conjunction with the driver assistance system, today's LED lights can also adjust the focus of the spotlight to prevent glare to others.

LED lamps have a lifetime of approximately 10,000 hours, approximately 10 times that of conventional bulbs. In terms of energy consumption, a single LED lamp unit has a power of 18 watts, while a xenon lamp has a power of 35 watts.

The importance of the control unit

Unlike traditional headlights, LED lights are not powered by a 12-volt electrical system and have their own unique electronic control unit.

In the latest adaptive headlamp technology, electronic control components need to perform more system cooperation tasks.

In some cars, daytime running lights are LED lights, while fog lights use halogen or xenon lamps. The control unit can simultaneously control LED lights and other types of lights.

LED light standard

The number of models with front LED headlights is increasing, and now even compact models are equipped with LED lights.

Future LED lights

In the future, LED lights can not only illuminate the center of the road, but also illuminate pedestrians on the edge of the road based on the driver assistance system. According to the navigation system information, the car will give directions to the driver in the form of LED light pulses. With the advent of matrix LED lamp technology, mechanical components will be abandoned in the future headlight unit, and thermal management and lighting control will become more complicated.

In general, future LED lights will be more than just a single lighting system that will be combined with automotive safety systems and auxiliary systems to provide drivers with greater comfort and ride safety.
