The XeTREME series is a true game-changer in aviation high-intensity LED landing and taxi light performance.
By out-of-the-box thinking, XeVision has achieved efficient and dependable extreme brightness for LED "light engines", with certified and published Lab measured outputs greatly exceeding anything currently on the world market.
High-power LEDs inherently generate a lot of heat while in operation. The excess heat needs to be dissipated quickly, otherwise, the system may suffer a possible thermal run-away which dramatically lowers the LED output, and lowers the LED lifespan, which in the worst case may even destroy the LED. Common solutions for LED lights are implementing passive heatsinks to address this adverse effect, however, usually not efficient enough. To avoid damage to the LEDs in those LED lights, the power to the LEDs is reduced by an electronic safety circuit with the negative result of significantly reduced brightness. In contrast, XeVision® opted for a very effective Active Cooling approach.
XeVision's proprietary active cooling design guarantees sustained highest light output and long component life by a meticulously designed cooling concept starting at the LED to substrate level, selecting low thermal resistance materials and TIM (Thermal Interface Material), and ending with a fan supporting pin fin heatsink very efficiently dissipating heat to the ambient air.
For the advanced high-efficiency design concept, XeVision selected state-of-the-art high-power LED chips and optimized TIR optics together with a protective high visible light transmission hardened AR (anti-reflective) glass. After several years of development and extensive testing, we established that the light fixtures were producing more than 96% of brightness even after days of continuous operation under ambient conditions, around 25ºC. Fixture and heatsink temperatures stayed well below 60ºC thanks to our proprietary no-compromise active cooling design for the LED light engine including the supporting control electronics.
Taxiing with the high-definition XV36-LED-7EL LED taxi light clearly demonstrates the benefits of the wide uniform light pattern of 34º, allowing illumination on both sides of the aircraft taxiing path with minimal disturbance for passing aircraft and vehicles. The rectangular beam shape with a 11º vertical beam angle makes this light very effective with the wide horizontal beam pattern, unlike circular taxi light beams.
The benefit of the combination of the XV36-LED-7UN landing light and the XV36-LED-7EL taxi light is enormous, providing a far reach of central illumination (7UN) and a superb uniform illumination to the sides (7EL). These characteristics combined, provide optimal benefits for ground and flight operation safety. Too bright? Just choose 50% light intensity, simply selected in the cockpit on the fly.
XeVision's proprietary strobe mode, dubbed XeStrobe™, is purposely designed by their engineers for better recognition. The XeStrobe™ pattern and high brightness light beam of this LED landing light is a perfect solution to mitigate bird strikes. Used together with the LED taxi light version, the wider taxi projecting angle helps to reach flocks of birds over a wider range. By using both Landing and Taxi fixtures with the XeStrobe™ pattern selected “To be seen” is a no-brainer even for birds. XeStrobe™ is far superior to the traditional wig-wag pattern.
