Analysis of Advantages and Disadvantages of Three Lighting Technologies for LED, OLED and Laser Lamps
Since its invention, light source technology has been widely used in all aspects of life, such as indoor lighting, television, etc.; and automotive lighting is a very important application area. With the increasing selectivity of automotive lighting, car companies are also painstakingly choosing which lighting technology to use. So how do you choose the right lighting system? This paper helps readers to fully understand their respective markets and prospects by analyzing the advantages and disadvantages of three lighting technologies: LED, OLED and laser.
(Left to right, LED, OLED, laser lights)
Advances in technology can always bring breakthrough changes to the industry, as does the automotive lighting market. With the continuous advancement of light source technology, the choice of automotive lighting has also changed. From the past fuel (candle, kerosene or acetylene, etc.) directly burned; to Edison invented incandescent lamps, automotive lighting entered the electrical age. Nowadays, with the continuous maturity of semiconductor light-emitting diodes in automotive lighting, the era of gas discharge (halogen, xenon) lamps has begun to come to an end.
At present, many foreign car companies such as Mercedes-Benz, BMW, Toyota, Ford, etc. have launched cool LED lights, LED lights have also opened their own car lighting era, LED lights have not yet stabilized, OLED, laser car The lights began to enter the highly competitive market.
In recent years, BMW, Mercedes-Benz, Audi, etc. are launching new cars equipped with OLED and laser headlight technology. In the future, LED, OLED and laser lights will be the three main technologies for car companies to choose lighting. The era of the three countries’ hegemony has just begun.
Advantages and disadvantages of LED, OLED and laser lamps
As can be seen from the chart, the three major lamp technologies have their own advantages and disadvantages. In terms of brightness, laser lights, OLED lights, and LED lights are in turn; in terms of cost, the opposite is true. The LED lamp technology is mature and can be seen in many cars. It should be said that in the future, the popularity of laser lamps and OLED lamps is huge.
At present, in the automotive lighting market, LED lamps have the largest market share, followed by OLEDs and laser lamps. After all, LED lamps have obvious advantages in terms of technology maturity and cost, which is why many car companies favor it.
The three headlights have their own uses in car lighting.
The advantages and disadvantages of LED, OLED and laser headlights determine its application. At present, LED lighting is used for headlight lighting and laser is also used for headlight lighting. OLED is used for taillights. In 2016, BMW introduced a concept car that uses an OLED car light source. Laser headlights have also ignited in recent years. BMW Audi and other car companies have launched new cars using laser headlights, and the sales volume is considerable.
Many cars nowadays have adopted a method of mixing two or two. According to relevant sources, this year Audi will use three kinds of headlights: ordinary LED, matrix LED and laser, and adopt through-type OLED taillights.
The choice of headlights is also a big selling point for new cars.
BMW I8 with laser headlights
Since the development of automobiles, the lights have become more than a large lighting tool for automobiles. Many car companies have made the lights a big selling point. According to OFweek Xiaobian, BMW has introduced a plug-in hybrid super sports car. The lighting uses laser headlights. At that time, the price was close to 2 million RMB. It is very expensive to think about it. It is reported that this car has been mass-produced, and the sales in foreign countries are quite good, and few people in China are interested.
At present, there are many companies outside the car that play with OLED and laser lights. In the domestic market, there are very few real applications. It is reported that BYD will launch a new OLED taillight car this year, the price is about 250,000. Many other car companies are on the sidelines and use less new technologies.
LED, OLED, laser lights, the future is "three legs"? Still dominate the world?The advancement of any technology is a great blessing in the industry. Lighting is an indispensable part of the car, and its development has a great impact on the industry. In recent years, car accidents at night have increased, as the high beam of the laser module can provide maximum light range, which will greatly improve the driver's night visibility. Incorporating the design and function of laser lamps into automotive lighting will bring great potential for the future development of laser lamps compared to LED light sources.
The development of laser headlights and OLED headlights is a good thing for the industry. They all have their own advantages, but from the perspective of popularization, cost and technical factors have a great impact. For ordinary car companies, no matter which technology is chosen, safety, cost and practicality are the main considerations. It is impossible to win the hearts of users by relying on the gimmick and cool appearance. LEDs, OLEDs, and laser lights have their own advantages and disadvantages. In the future, are three technologies coexisting, or is it a technology leader? In the end, consumers have the final say.
Among the three technologies of LED, OLED and laser light, which technology do you think will become the mainstream choice for automotive lighting? Maybe everyone has their own answers, but I hope that they will each play their own advantages and support the automotive lighting market.
