Yesterday's WiFi wireless smart lighting solution, can you see it? Have you ever thought of any thoughts and inspiration after reading it? Today, I also bring you a few automotive LED solutions for smart lighting. I hope to bring you some new insights and take notes if necessary.
1. Osram's passenger car LED lighting solution
Trustworthy car lights are the key to safe travel. New lighting solutions better illuminate the area ahead, allowing drivers to recognize signals, obstacles and dangers more quickly. Once the brightness is increased, your driving experience will also improve. The light from the headlights relieves eye strain, reducing the risk of fatigue driving and allowing you to reach every destination safely.
Osram is the world leader in passenger car lights and offers a wide range of automotive LED products. In North America, Osram has also provided a complete headlight system. In Europe and Asia, OSRAM offers a single source of light and has worked with leading companies in the headlamp industry to develop high quality lighting solutions for passenger cars.
Osram passenger car LED solutions mainly provide halogen lamps, high-pressure gas discharge lamps, LED lights, off-road lights, auxiliary lighting, and related automotive LED accessories.
Osram halogen lamps offer 100% light output and excellent light quality, making them one of the long-lasting and reliable economics. Osram halogen lamps can be divided into three series: Cool Blue Intense, Ultra Life and Original Line.
The COOL BLUE INTENSE halogen lamp, which is 20% brighter than the standard halogen lamp and has a color temperature of 4200, is considered the bluest halogen lamp and is named Blue Intense. Blue Intense halogen lamps are ECE compliant and suitable for all headlight functions.
The Osram Ultra Life series is three times longer than traditional halogen lamps, not only for drivers who travel frequently, but also for owners who have difficulty getting headlights and lights to reduce their workload on the shop floor with the new ULTRA LIFE. Cost savings.
The OSRAM Original Line series offers higher quality brightness, reliable service life and excellent price/performance ratio compared to standard lighting solutions. Whether it is used as a genuine car or as a spare part, new models of famous car manufacturers can always be found. It's figure.
Osram high standard high intensity gas discharge lamp:
Osram high-pressure gas discharge lamps are intended for passenger cars. They offer a large number of light sources, provide high-intensity road lighting, and set high standards in terms of efficiency and longevity. XENARC lamps are only allowed for special xenon headlights. These XENARC lamps must be equipped with a headlight beam auto-adjustment and a special cleaning system. Due to the high pressure rating, XENARC D2 and D4 lamps and XENAELECTRON ballasts can only be replaced by specially trained professionals.
In addition, OSRAM LED lamps also provide a series of LED exterior lighting such as daytime running lights and fog lights, and are equipped with portable LED lights for external use. Whether in glove boxes or pockets, innovative LED accessories can be used. Meet your design requirements.
2, NXP (NXP) automotive lighting drive and control ICNXP offers a fully integrated solution for automotive solid-state lighting (SSL) applications. These include the ASLxxxx family of multi-channel LED drivers, which are fully integrated solutions that guarantee system flexibility and stability for automotive LED lighting applications. In addition, NXP offers the TDA3629 headlight position controller to support adaptive beam adjustment (ADB) solutions.
Both solutions significantly improve system performance and minimize the overhead associated with different applications.

Light level controller
The NXP ASLxxxx family of LED driver ICs is a vehicle-specific application-specific standard product that provides a fully integrated solution for automotive LED lighting applications. Not only do they provide the functionality needed for today's and tomorrow's automotive LED applications, they also maintain system flexibility, support design reuse, and offer high scalability and price/performance.
The Lecht Weiten Steller (LWS) is a monolithic integrated circuit for passenger cars. With this device, the driver of the car can use the potentiometer on the dashboard to define the beam height of the headlights of the car.
The driver can adjust the beam height simply by selecting a new position, and the TDA3629 can raise or lower the beam angle by activating the control motor. Its low positional error allows the driver to accurately position his headlight beam, maximizing the road and not glaring any oncoming vehicles. The device prevents temperature rise above 160 oC and electrical transients, as well as undervoltage/overvoltage protection and broken wire detection.
3, Infineon car dedicated LED driver

LED and light drivers for automotive lighting applications
Infineon offers integrated automotive lighting solutions for both internal and external applications, whether inside or outside the vehicle, such as protected single-channel, multi-channel power switches, and important products such as power MOSFETs PROFETs that integrate intelligent diagnostics and protection. In addition, the SPOC family offers control, configuration, and diagnostic serial peripheral interfaces (SPI).
Infineon's automotive-specific LED lighting driver products include linear LED drivers for taillights, high-current LED drivers for headlights, and switching DC/DC buck and boost regulators for optimum energy efficiency.
