Based on the revolutionary SC ^® technology platform, Cree XLamp ^® XM Series LEDs combine high light output, high reliability and high efficacy with LM-80 testing to meet ENERGY STAR requirements. The high-bay lights and street lights have laid a good foundation for the design of lamps with high light efficiency requirements. The XLamp ^® XM-L2 LED is the industry's brightest, highest performance single-chip LED device delivering 186 lm/W of light efficiency. Compared to the previous generation of XLamp ^® XM-L LEDs, lighting manufacturers are provided with 20% higher light efficiency and higher cost performance (lm/$). The brighter, more efficient XLamp ^® XM-L2 LED delivers immediate performance gains. At the same time, XLamp ^® XM-L2 LEDs help lighting manufacturers achieve the same brightness and use fewer LEDs at lower cost, and can help increase brightness with the same number of LED devices and the same power. Level.

Generally speaking, outdoor lighting requires high luminous efficiency, high luminous flux, high maintenance characteristics, etc. In addition, it requires more safety protection than indoor lighting, and requires better performance in terms of life and reliability. Light efficiency, optical communication, excellent light color quality, longevity and reliability are the advantages of the Cree XLamp® series. For the various street lighting products on the market, the high-efficiency series XLamp ^® XM-L LED, XLamp ^® XM-L2 LED devices are used in some of the module solutions and customer applications of street lighting applications, with lighting manufacturers or designers. Share and discuss with colleagues in the industry.

XLamp ^® XM-L2 LED is one of Cree's best LEDs. Based on good performance, long life and color coordinate stability, and high cost performance, the 5,000 K color temperature and T6 are the design. Preferred

LED luminaires require a good cooling system to ensure long-term reliable operation of the luminaire. In combination with the optical and thermal requirements of the street lamp, we use the high-conductivity aluminum alloy structure radiator (LK-120531A) of Nanhai Yixin Aluminum Products Co., Ltd., the aluminum alloy material is AL 6063, and the surface anode is processed to ensure the LED operation. The junction temperature can be applied to the same size street lamp products in a suitable range.
