2023-09-05, Four design dimensions of automotive lighting

LED lights have been widely used in a variety of lighting environments, and with the upgrading of technology, light efficiency is also gradually improving, showing more and more advantages in practical applications. Nevertheless, in the endless pursuit of efficiency, efficiency is still one of the key design considerations because of the large amount of use and long time of automotive lighting. Efficiency is critical in electronic systems where space is limited, and in these designs the LED driver is installed very close to the LED assembly in the headlight, taillight, or side turn indicator.
