With the accelerated penetration of LEDs, the background of the upgrading of electric intelligent driving lighting technology. As the main automotive lighting and indication, the headlights are the eyes of the driver. Under the wave of intelligence, the realization of more beautiful, more durable, safer, more energy-saving and more personalized automotive lighting is the constant pursuit of every traditional car manufacturer and new energy car company.
This article briefly explains the classification, upstream and downstream, industry benchmarks, and technology development direction of the headlight industry. For those who are not very familiar with the knowledge of headlights, it can be clear at a glance and step by step.
1. Functional classification of automotive lighting
Automobile lighting mainly includes headlights (headlights), front fog lights, daytime running lights, footlights, step lights, door lights, trunk lights, vanity mirror lights, front interior lights, side interior lights, license plate lights, interior wall lights, ceiling lights, reading lights, engine compartment lights, key backlights, etc.; signal lights mainly include rear taillights, rear fog lights, side turn signals, driving lights, parking lights (double flash), reversing lights, small lights (width lights), position lights, high-position brake lights (brake lights), instrument indicators, turn indicators and warning lights (oil pressure, brake system vacuum, tire pressure, fuel level, etc.).
2. Technical classification of automotive lighting
Automobile headlights are divided according to light source technology, mainly incandescent lamps, acetylene lamps, halogen lamps, xenon lamps, LED lamps, OLED lamps, laser lamps, etc. LED headlights replace traditional halogen lamps and xenon lamps, which not only saves energy but also improves the response speed of headlights, and also gives headlights greater design flexibility.
New energy smart cars, analogous to the development of smart phones, create new selling points. Headlights deservedly become one of the most popular parts and a breakthrough point for technological innovation of car manufacturers and their suppliers. New technologies such as matrix LED, DMD, OLED, Micro LED, MLA, Mini LED, etc. continue to progress and mature, allowing high-pixel ADB, DLP projection lamps, ISD signal lamps, etc. to be applied, enhancing the differentiated value. The technical routes of smart headlights (headlights and taillights) are mainly the following: LED matrix (HELLA), μAFS (Osram), LCD (HELLA), DLP (Texas Instruments), Blade scan (Koito) and MEMS (Bosch).
III. Market size of automotive lighting
In 2022, the global automotive lighting market sales were US$35.65 billion, and it is expected that the automotive lighting market sales will be US$47.56 billion in 2028, with a CAGR of 4.9%; the global vehicle value of automotive lighting was US$578.8 in 2022, and it is expected to be US$706.1 in 2028, with a CAGR of 3.4%.
