2016 automotive LED lighting market focus is headlamps

Tencent digital hearing in the design of the front face of the car, the two headlights is the best carrier transmission charm. Sometimes, the headlight design and internal structure, directly determines the success or failure of this designer. Encountered in the interim changes, the change in the shape of the headlights, but also to highlight the difference between the most points.

From halogen headlamps, xenon headlamps, and then gradually spread the popularity of LED headlamps. The development and application of lighting technology, but also represents the continuous iteration of automotive technology. Perhaps in 5 years, after 10 years, laser headlights will become a standard production car.

With the iteration of the lighting technology, the interior design of the headlight is becoming more and more important. Today, LED band has become an integral element of the embodiment of luxury brand identity (do not confuse with the day lights).

This is because the early halogen lamp is an incandescent lamp, which is based on the chemical reaction of tungsten filament and halogen gas source. This principle determines the structure of the inside of the lamp bowl is basically fixed, in addition to the installation of a lens, there is no plasticity and decorative.

Later, the gradual popularization of xenon lamp (HID), is a kind of cold light source, compared to halogen lamps, xenon lamp is smaller, lower energy consumption, irradiation distance. Because the xenon lamp uses the electronic activation gas to glow, the tungsten filament is not needed, and the service life is longer.

The xenon lamp of the headlight assembly has a ballast parts, it can in an instant power on the vehicle will enhance the voltage of 12V to 23 thousand V, using super voltage activated lamp xenon iodide and other inert gases, light source. This principle is essentially the same as the halogen lamp, so the light source also exists in the case of scattering. In this regard, xenon headlamps will be equipped with a lens to focus light.

However, starting from the xenon headlamps, the light source to reduce the volume of a lot. Therefore, in the design, the designer to play a larger space. Most importantly, some of the features of the headlamps are also more abundant. Such as far and near light automatic adjustment, with the steering, high and low adjustment, so that the user experience to enhance the headlights.

Next is the key, that is, LED and laser headlamps. First say LED. As a gradual popularization of lighting technology, LED technology from the field of consumer electronics to the automotive field. During the 2015-2016 iteration of the automotive industry during the iteration, the new models equipped with LED headlamps accounted for a high proportion.

It can be said that this wave of tide officially confirmed the popularity of LED lighting technology trends. Several representative models including the new BMW 7 series, Lexus RX, Volvo S90, Audi A4 and so on. The Mercedes Benz began to gradually update the product sequence from the middle of 2014, from the new C start line comes standard with LED light source (low beam, high beam is still a halogen).

Compared with the xenon lamp, LED headlamps light source is smaller, which means that the designer can be inside the lamp body rich imagination. With the LED lamp with decorative strips on the popularity of light light source distance also appeared in amazing shape, the most impressive than the Lexus diamond matrix design.

The application of LED technology in the line of light, width lamp, brake light has been widely used, but also on the headlights are rare configuration. Like the Infiniti Q50 such vehicles, equipped with the LED for its many points. Of course, high beam and Mercedes Benz is still halogen. Lincoln MKZ is further, the direct use of LED far and near light integrated design.

As a widely used light source, LED into the car headlights is not accidental. In 5 years ago, equipped with all the LED light source models rare. With the capture of engineers, the LED light source irradiation distance and physical spectrum penetration ability have been improved, in line with the application level of the vehicle level.

As a result, LED headlamps in performance has been fully beyond the xenon lamp, and has lower energy consumption and more flexible body. In this field, the most representative of Audi's Matrix matrix all LED headlamps assembly. About two headlamps, each headlight is composed of 25 independent LED light source. Such a highly modular design, so that the headlights in the functional design and user experience with more possibilities.

Modular means that each LED light source can independent light and closed in the Audi Matrix headlight assembly, high beam irradiation in reverse to the car will automatically shut down part of the light source, keep another part of the body is not exposed to light. This requires a set of separate computing systems, including sensors, cameras, and processors.

In addition, the intelligent headlight design, but also to remind the driver. For example, in the design of Matrix headlamps, when the vehicle is detected in front of pedestrians, headlights will flash three times to help the driver to take note of pedestrians.

Of course, the most futuristic, it is undoubtedly the first to introduce the mainstream market by BMW I8 laser headlights. Compared to LED, the laser light emitting element is smaller and the light source is changed from the led to the laser diode. At the same time, in the brightness of the radiation, the laser headlamps can reach 170 lumens / watt, while LED is 100 lumens / watt. Compared with the latter, the laser light energy consumption can be reduced by 30%.

In the irradiation distance, laser headlights is actually a good complement to LED. For LED, because of the weak penetration of its physical spectrum, the distance between the lamp and xenon lamp has no absolute advantage. But the laser headlights, then
