Cree Introduces New High-Intensity LEDs to Deliver More Than Double Light Performance

On May 4, 2015, China's Shanghai Science and Technology Co., Ltd. (Nasdaq: CREE) announced the launch of a new high-intensity XLampXP-LHILED device with a single chip, with a 50mm diameter optical lens at 10W, available More than 100,000 cd light. The high-intensity XLampXP-LHILED device is based on Cree's breakthrough SC5 technology platform, which provides more than double the light intensity under the same optical matching conditions compared to the industry's highest performance single-chip XP-LLED devices. The high-strength XLampXP-LHILED device is available in the existing 3.45mm x 3.45mm XP-L package, enabling lighting manufacturers to rapidly improve lighting product performance and reduce lamp size in applications such as track lights, outdoor lighting, and stadium lighting. Reduce system costs. The high-intensity XLampXP-LHILED device features Cree's innovative primary optics design that dramatically reduces over 50 optical companion sizes and delivers ultra-high light intensity at 185lm/W (@1W). The high-intensity XLampXP-LHILED device provides an immediate boost to the original XP-based luminaire design, helping lighting manufacturers achieve higher light levels and fewer luminaire redesigns to accelerate time to market. JonQuenzer, electrical engineer at Trek, said: The high-intensity XLampXP-LHILED device offers a great option for our next-generation luminaires. We can quickly improve the light efficiency and light intensity of lighting products without changing the original XP-G2-based optical or drive design. Dave Emerson, vice president and general manager of the LED business unit, said: The high-strength XLampXP-LHILED device once again proves that Cree's unremitting efforts for innovation can achieve high luminous flux and high light intensity in a small size specification. XP-LHILED will enable lighting fixture designers to fundamentally change the original mindset when faced with the choice of LED devices for high-intensity lighting applications. The XP-LHILED will also enable lighting manufacturers to achieve performance levels that were previously impossible. High-intensity XLampXP-LHILED devices provide performance characterization and binning at 1,050 mA, 85C temperature, CRI up to 90, color temperature 2,700K to 8,300K, and are ENERGY STAR certified for ENERGY STAR The manufacturer of lighting fixtures provides a 6,000-hour LM80 test report. Sample applications are now available for high-strength XLampXP-LHILED devices and can be mass-produced with standard lead times.

Loader Air Intercooler

Principle of loader air intercooler: when the air enters the Engine Turbocharger, its temperature will increase greatly, and its density will decrease accordingly, and the intercooler is playing the role of cooling air, high temperature air through the intercooler cooling, and then into the engine. If the lack of intercooler and let the pressurized high temperature air directly into the engine, it will cause the engine knock or even damage flameout due to high air temperature.

Through an opening in a hood for cooling air, so before the car started, inter-cooled device will only by some hot air blowing in from the engine compartment, while the cooling efficiency have been affected, but because of the inlet temperature rise in such a case, so the engine fuel consumption will decline a lot, this also indirectly reduce the efficiency of the engine.

Function:

1, the role of cooling air, high temperature air through the cooler cooling, and then into the engine.

2. Reduce engine fuel consumption.

3, improve the adaptability to altitude. At high altitudes, a compressor with a higher pressure ratio can be used with intercooling, which makes the engine more powerful and improves the adaptability of the vehicle.

4. Improve the matching and adaptability of the supercharger.
