Standardized LEDs to slash the cost of automotive signal lamps

June 12, 2018 // By Julien Happich
Osram's XLS (eXchangable LED Signal) standardized LED light sources are aimed at signal light applications in the automotive industry.

By combining standardized light sources and LED technology the Osram expects to fundamentally change the automotive signal lamp sector, enabling a uniform platform with four different light sources to cover all the important signal applications in vehicles. This will allow simple replacements, reduce complexity and overall costs for car manufacturers and it will lead to faster development processes thanks to adapted standards, the company anticipates. The UN/ECE (R128) standardized lamps will be available in four types for different signal applications in yellow (LY5), white (LW5, L1) and red (LR5). The yellow LY5 with 280 lumen and a life of up to 4,000 hours is used for turn indicators. LW5 is a white signal lamp for reversing and DLR lights with 350 lumen and a life of up to 5,000 hours. The two other members of the XLS product family currently in planning are a red brake, rear and fog light (LR5), which provides up to 4,000 hours of light with a luminous flux of 120 lumen, and a white high-precision fog light (L1) with up to 350 lumen and a life of up to 5,000 hours. With protection against electrostatic discharge, polarity reversal and overvoltages the Osram XLS products comply with all standard requirements for modern vehicle electronics. Osram uses chip-on-board technology for its XLS light sources. This enables the LED chips to be spaced very close to one another with common optics.

The LED-based signal lamps are scheduled to appear on the roads from the fall of 2018.
