Headlights are known as the eyes of cars. Whether the vehicle's shape is good-looking is closely related to headlights.
With the development of automobiles, headlights have also gone through the era of acetylene lamps, incandescent halogen lamps, xenon lamps, and the current era of LED and laser headlights. Its function has also evolved from traditional lighting to atmosphere creation, body beautification, and even emotional interaction. And with the advancement of automobile electrification and intelligence, what is the trend of headlights?
The advent of the smart electric era has allowed car owners to feel the fun of car intelligence, the safety of assisted driving, and the energy saving of electrification. Automotive suppliers and car companies have also begun to work hard on headlights.
Energy-saving-oriented, lightweight route. The energy saving of vehicles is not only about high-power power systems, but also the energy consumption of headlights. For this, we must start with the volume and lightweight of headlights. For example, the SSL | HD headlight module reduces the space by 75% compared to traditional headlights; in addition, the latest FlatLight can reduce the energy consumption of vehicle taillights by 80%. Guided by intelligence, manual to adaptive. With the continuous advancement of intelligent driving, the vehicle's cruise has been upgraded from the previous fixed-speed cruise to the currently widely used L2 adaptive cruise. At this time, the vehicle can automatically adjust the speed according to the judgment of the speed of the vehicle in front and the surrounding vehicles.
Similarly, adaptation has also been applied to headlights, such as the high and low beam lights from manual control to adaptive. At this time, the vehicle can adjust the high and low beams according to the ambient brightness, oncoming vehicles, etc., and can even project guide lines at night, and project lane change signs when sensing road construction ahead. Guided by the driver's emotions, different patterns cater to different needs. In addition to meeting the necessary lighting needs, car companies have also widely integrated optical electronics, algorithms and programming into life. Car lights can also project interactive signals such as welcoming, farewell, and mood to meet the emotional needs of consumers. For example, Tesla can currently perform a light show accompanied by music after parking.
Car companies differentiate themselves and show the extended attributes of headlight modules. Car companies can customize their needs and use the flexibility and expansibility of the headlight module to reprogram the light language and achieve differentiation of the lights. This can strengthen the brand attributes, and the vehicle can easily attract attention on the road, thus playing a role in publicity. Taking the taillights as an example, many car companies have added signals, logos, and personalized images like "I love U" to the through-type light strips; and the taillights on both sides have achieved infinite extension in geometric patterns, pursuing slenderness and refinement.
From the trend point of view, headlights are developing in the direction of low energy consumption, intelligence, customization and personalization. In this process, how to better provide diversified technologies and products for vehicle manufacturers and consumers in the new era has become an important issue for technology providers.
Through the intelligent control of up to 25,000 LED pixels per chip, more interactive and safe expressions can be achieved. In addition, it is 75% smaller in size than the previous generation module, which creates new possibilities for the integration of headlights on the vehicle architecture. In addition, because electric vehicles no longer need traditional radiator grilles, this creates new possibilities and flexibility for the design of the front face of the car. In this way, the digital physical front panel can become a differentiating design element for electric vehicle brands.
