I don't know if you have found that today's car lights are more and more advanced, and the degree of integration is getting higher and higher. Colleagues in the development of automotive technology, lighting technology is also constantly changing.
And the headlights are still the eyes of the car, if the headlights and taillights are well-made, they can not only enhance the attractiveness of the design, but also give people a good sense of technology. Most importantly, good lighting also reduces the risk of accidents. This is an important reason why domestic and foreign automotive safety organizations regard headlights as one of the safety norms.
In the past, automotive lighting began with lighting the wick. Then, with the invention of electricity and light bulbs, cars were able to drive on dark streets.
Early lighting techniques were developed to see farther and brighter in the dark. From ordinary bulbs to halogen lamps, xenon lamps, and then LED headlights, to today's laser headlights, headlights are becoming more and more advanced.
Today's automotive headlights have long been illuminated far and bright, and now the headlights are focused on how to maintain a bright forward view without dazzling opponents. The lighting area can be divided using multiple LED modules, or the light itself can be divided by rotating the blades. Recently, a technique that utilizes polarization techniques to split light into pixel units to make it look like a single display that can provide sharper contrast and even create simple animation effects is in mass production.
In addition, the headlights also have a tendency to miniaturize, and in the past a large circular reflector was needed, so the headlights occupied a lot of space in the front. Recently, however, headlamps have become smaller and smaller because they emit light directly through the projector without the need for a reflector. Thanks to this, designers can more freely realize the various designs of appearance and styling.
As lighting technology evolves in various forms, consumers are curious about it. A typical example is that the more expensive the vehicle, the more complex the interior of the headlights, and the better the lighting effect.
However, from a technical point of view, it is difficult to simply summarize the performance when the number of light groups is larger. However, the greater the number of lights, the better the lighting performance.
There are also many low-cost LED headlamps that are usually equipped with reflective MFR (Multi Face Reflector) LEDs, while high-end models are equipped with projected LEDs.
Projection LED lights have another advantage, they can realize adaptive function (matrix) headlights, which is also a recent design trend, and it makes it possible to be thin and light. The difference is not only in terms of brightness, but also in terms of functional implementation.
And with the advancement of headlight technology, fog lights have gradually disappeared. With the advent of high-performance headlamps using LEDs, the effectiveness of fog lamps has been greatly reduced. In the past, fog lights were used to make up for the lack of headlights, and now the headlights themselves can cover the area of fog lights.
Lights are a very attractive part of the car, it includes safety, technology and design. Recently, automotive taillights are gradually using OLED instead of LEDs to achieve more brilliant results and reduce the size.
