Osram to launch LED-based automotive signal lamps
The Munich-based Osram is launching XLS (eXchangable LED Signal), standardised LED light sources for signal light applications in the automotive industry. By combining standardised light sources and LED technology, the company will fundamentally change the automotive signal lamp sector.
“For the first time, a uniform platform with 4 different light sources can cover all the important signal applications in vehicles. This allows simple replacements, reduces complexity and overall costs for car manufacturers and leads to faster development processes thanks to adapted standards,” Hans-Joachim Schwabe, CEO Specialty Lighting, Osram, said. The LED-based signal lamps are scheduled to appear on the roads by October 2018.
Over the past few years, LED technology has brought many benefits in terms of design and has led to greater energy efficiency. Therefore, a bewildering array of vehicle-specific solutions has been created. To reduce this complexity, Osram has developed an innovative standardised LED light source for signal light applications. With the XLS product family Osram is launching a signal light portfolio that offers all the innovative benefits of LED technology while offering the proven benefits of traditional lamps such as standardisation and exchangeability.
A single platform
The UN/ECE (R128) standardised lamps will be available in 4 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 2 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 highprecision 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-onboard technology for its XLS light sources. This enables the LED chips to be spaced very close to one another with common optics.
The XLS product family delivers a wide range of benefits for consumers, headlight manufacturers and car manufacturers. A standardised platform for LED signal lamps reduces the number of individual solutions for vehicle models. Integrating the heat sink and electronics in the light source eliminates the costs for their design and approval for each individual solution. All this considerably reduces overall costs for car manufacturers across the various areas – such as the supply chain and quality control. The reuse of design modules and the same platforms also cuts down on the time, effort and costs of development. For car workshops and car owners a standardised solution means the light sources can be directly replaced in the event of a fault, which in turn means lower repair costs and greater road safety. Long-term availability of the lamps will encourage the establishment of the XLS product family.
Series production of the lamps in the automotive plant in Herbrechtingen, Germany, guarantees premium quality and is an important milestone in the further development of standardised automotive light sources. Customers of XLS products benefit from the many years of experience at this plant in manufacturing car lamps.
The standardised XLS product family enables design cycles to be shorter and complexity to be reduced, making it a pioneer for the widespread penetration of LED technology in high-volume vehicle segments. Osram’s launch of LY5 and LW5 in yellow and white means that for the first-time users (Tier1/OEMs) can equip vehicles with standardised exchangeable LED signal light sources in all signal applications.
