Application of Optics in Vehicle Projection Headlamp Design

Under the background of automobile intelligence to further improve driving safety, in order to enhance the interaction between vehicles and pedestrians, the vehicle projection headlamp can play a role in alerting pedestrians outside the vehicle through the precise control of lights, such as the corresponding pattern projected on the road surface. This article will introduce the application of optics in the design of vehicle projection headlamp.

Lighting Effect Improvement

By individually adjusting the angle, brightness, and pattern of each light source, the vehicular projection headlamp achieves more refined control of the lights and a higher definition display effect. At the same time, in some control strategies, in order to adapt to the different requirements of the vehicle lighting in different driving conditions, the vehicle projection headlamp will implement different strategies of left and right separate control or unified control to provide drivers with a better view.

Higher Resolution

The vehicle projection headlamp allows control of tens of thousands of individual pixels. By changing the angle of reflection of the light, the light can create dark zones in a specified area. By controlling the frequency of the light, the projection pattern can be dynamically displayed to alert pedestrians or cyclists in low light conditions.


Due to the large number of light sources in the vehicle projection headlamp assembly, the system is able to adjust the light with high precision through the control of each micro-lens, thus precisely controlling the headlamp to adjust the angle of light transmission and the size of the dark zone. Under the premise of ensuring the driver's maximum field of vision as much as possible, the vehicle projection headlamp can cause no light pollution to oncoming traffic and people.


By adding appropriate filters and optical components to the vehicle projection headlamp, the optical projection technology can realize different lighting effects, such as inter-oral running lights, turn signals, anti-glare, and so on. This not only improves the recognition and aesthetics of the headlamp, but also can remind other drivers to pay attention and reduce accidents through special lighting effects.

In conclusion, optical projection technology has an important value in vehicle projection headlamp design and lighting effect improvement. It is believed that optical projection technology will have more applications in the design of headlamps and make greater contributions to the safety and comfort of night driving.
