Car lights are important auxiliary tools in automobiles. In addition to lighting, warnings, and instructions, appearance, performance, and durability are also crucial. That is why various car companies work hard on lights to gain market competitiveness.
Currently, the most common car lights on the market are mainly divided into three categories: halogen, xenon, and LED.
The advantages are strong penetrating power, fast lighting, and low cost. The disadvantages are weak brightness, small range, serious heating, yellowish light color, and short service life.
The advantages are high brightness, light color close to sunlight, and long life. The disadvantages are complex structure, long start-up time, and poor penetration ability in rain and fog.
The advantages are lower cost than xenon lamps, energy saving, fast response, high brightness, small size and long life. The disadvantage is that it has poor heat dissipation and is difficult to maintain.
These common car lights are not introduced today. Recently, Mercedes-Benz released a preview of its concept car Mercedes-Benz EQA, which also includes detailed pictures of its OLED light set. The cool and sky-shaping light set is really eye-catching. OLED is popular again.
So what exactly is OLED? The English name is Organic Light-Emitting Diode, which is the organic light-emitting diode. It was invented by Chinese-American Deng Qingyun in 1987.
OLED is based on LED with the word organic added, but it is completely different from LED.
First of all, OLED has a very large light-emitting area, is self-luminous and does not require a backlight. The heat generated during operation can be dissipated in time without the need for a heat dissipation device. Therefore, OLED can be very thin and light, saving space. When the new A8 was released a few days ago, the OLED headlights at the rear stole the show. However, if you look closely, you can see that the light source is an extremely thin sheet and does not require optics such as reflectors. Components, the most prominent manifestation is the subversive appearance.
Moreover, it has high transparency and brightness, and the colors it presents are more accurate. Isn’t this full of “B grid”? If OLED is used in household glass in the future, it will be very high-end when you think about it. It will be glass during the day and transform into a light at night.
Secondly, OLED is a highly malleable substance and can be designed into a variety of shapes. In the past, lamps were for lighting, but now, lamps are even more works of art.
Because of this, OLED is becoming more and more unique as a light source. Think about the OLED screen of a TV, and then imagine the car lights. If the taillights use OLED, and the left and right steering are displayed in the form of text, animation, or programmable, then the taillights alone will be enough to play for a year.
Judging from the official pictures of the recent Mercedes-Benz EQA, there is already a trend towards this direction, where technology and beauty coexist.
In addition, OLED headlights save more power and have a longer life than ordinary LED lights.
But when it comes to OLED, the first one to be equipped is not the new A8 nor the Mercedes-Benz EQA. As early as 2015, BMW released the mass-produced car M4 GTS using OLED taillights, and then Audi also released a model using OLED taillights in 2016. Model - Audi TT RS. Although Audi seems to be a little slower, there is a saying that goes, "Lamps produced by lighting manufacturers must be high-quality products." Audi's OLED technology is also the most popular among car companies at present. Once released, I photographed the BMW on the beach.
However, models such as TT RS and M4 GTS are limited edition models, and the new A8 is a different story. As Audi's flagship model, the A8 is more representative in terms of popularity and user range. However, the new A8 still only uses OLED for its taillights.
The Mercedes-Benz EQA is completely different. From the front armament to the rear, it is full of dazzling skills. This time, even the "light factory" is ashamed.
However, OLED also has its own shortcomings. First of all, OLED is like the screen of a mobile phone. If it is broken, it can only be replaced, but cannot be repaired. So if the headlights are crashed, the first thing to consider is the high price of the headlights. Can you stand the beauty regardless of the cost?
No matter how beautiful the car lights are, no matter how powerful the future technology is, the main purpose of the car lights is to assist the driver in driving safely. No matter how dazzling your car lights are, you can't relax your vigilance when driving. Safety is always the most important thing.
