Light as a tool car important, in addition to lighting, warning, indicator, appearance, performance, durability is crucial, so there will be a variety of car prices in the hard light, in order to win the market competitiveness.

At present, the most common lights on the market are mainly divided into 3 categories, halogen, xenon, LED three.

The utility model has the advantages of strong penetrating power, fast lighting and low cost. Disadvantages are weak brightness, small range, serious heat, light yellow color, short service life.

The advantages of high brightness, light and sunlight close, longer life. The disadvantage is that the structure is complex, long starting time, rain and fog days poor penetration.

The advantage is that the cost is lower than xenon lamp, energy saving, quick response, high brightness, small size and long service life. The disadvantage is poor heat dissipation, not easy to maintain.


These lights are not common to introduce today, Benz recently announced its concept car Benz EQA Trailer map, including the detail of the OLED lamp group, light group mad pull cool hanging fried days really let the other OLED and a fire.

So what is OLED? English is Organic Light-Emitting Diode, that is organic light-emitting diode, invented by Chinese Deng Qingyun in 1987.
OLED adds a word organic (Organic) on the basis of LED, but it's completely different from LED.

First of all, OLED has a very large luminous area, and self luminous, without backlight, the heat generated by the work can be emitted in time, without heat dissipation device. So OLED can be very thin, some time ago to save space, the new A8 release, OLED headlights tail out of the limelight, but careful observation, the light source is a very thin sheet, optical components without reflector and the like, the most prominent manifestation is the subversive value of yan.
And it has the perspective and high brightness, the color is more accurate, this is not "B" full? In the future, if the home glass is OLED, think of it is also very tall, the day is glass, night turned into a lamp, is a light.

Secondly, OLED is a very strong plastic material, can be designed into a variety of modeling, once the lamp is for lighting, and now, the lamp is a piece of art.

In this way, OLED becomes more and more unique on the way of making light source. Imagine the OLED screen of the TV, and then think about the car lights, if the taillights use OLED, left and right turn in text, animation, or programmable, that only taillights enough to play for a year.

From the recent Mercedes Benz EQA from the official chart, there has been a trend towards this direction, the coexistence of technology and beauty.
In addition, OLED headlamps are more energy saving and longer life than ordinary LED lamps.


But when it comes to OLED, the first equipped with the new A8 also is not more than the Mercedes Benz EQA, in early 2015, BMW released the M4 GTS production car using OLED taillights, then Audi in 2016 also released OLED taillight models -- Audi TT RS, although Audi seemingly slow some, but there is a saying well, "the lamp factory produced, will be fine," Audi's OLED technology is currently playing the 6 car prices, was released, BMW will be shot on the beach.

However, TT RS, M4 GTS these models belong to limited models, and really to the new A8 is another scene, A8 as Audi flagship model, whether it is from the visibility or user range are more representative. However, the new A8 is still only taillights applied to the OLED.

Mercedes Benz EQA is completely different from the front to the rear of the car, armed, virtuoso feeling overwhelmed, "the lamp factory" humbled.

  
However, OLED also has its own shortcomings. First, OLED is just like the screen of a mobile phone. It can only be changed and cannot be repaired. So, if the car hit, the first thing to consider is the high price of the car lights, regardless of the cost of beauty, you can bear it?

  
No matter how beautiful the lights are, or how powerful the future technology will be, the main purpose of the headlights is to assist the driver in safe driving. Car lights again, can not relax vigilance when driving, safety is always the most important.
