Cree promotes the popularization and application of LED lighting through persevering innovation, and implements the mission of Cree, leading the LED lighting revolution, eliminating low-energy lighting, and fully accelerating the wide application of LED lighting. Cree's LED-leading technology helps to achieve significant energy-saving effects on road lighting, and fully meets national road lighting standards in terms of light efficiency, brightness, illumination, heat dissipation, and longevity, achieving faster return on investment, and brand and knowledge. The property rights advantage protects customers and helps customers lead the market. Technology leadership will better promote market leadership and help companies achieve stronger growth in LED lighting revolution. For the field of LED road lighting, Cree currently introduces XM series, XP series, XT series, XB series, CXA series and other cost-effective lighting-level LED products, fully satisfying customers' product design requirements for different market positioning, helping customers achieve lower Products and solutions for system cost and higher lighting performance. This article will share the Cree Lighting XM series LED and road lighting reference solutions, while Cree looks forward to more technical exchanges with industry peers in the future.
The Cree XLamp XM Series LEDs are based on the revolutionary SC® technology platform, combining high light output, high reliability and high light efficiency. They have passed the LM-80 test and meet the requirements of ENERGY STAR. These are highly luminous. 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 XLampXM-L LED, 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 levels with the same number of LED devices and the same power. .
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 in the street lighting application of some module solutions and customer 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 file are the first choice for this design. ;

Wireless Gaming Keyboard
Wireless Gaming Keyboard is a keyboard disk with no direct physical connection to the computer, through infrared or radio waves to send input information to a special receiver. Bluetooth devices, to be precise. The so-called Bluetooth technology, in fact, is a short-range radio technology, the use of "Bluetooth" technology, can effectively simplify the communication between mobile communication terminal devices such as palm computers, laptops and mobile phones.The so-called Bluetooth technology, in fact, is a short-range radio technology, the use of "Bluetooth" technology, can effectively simplify the communication between handheld computers, laptops, mobile phones and other mobile communication terminal devices, also can successfully simplify the above devices and the Internet communication between the Internet, Thus, the data transmission between these modern communication devices and the Internet becomes more rapid and efficient, which broadens the way for wireless communication. Bluetooth supports point-to-point and point-to-multipoint communication using a decentralized network structure, fast frequency hopping and short packet technology, and works in the 2.4ghz ISM (industrial, scientific, and medical) band used worldwide. Its data rate is 1Mbps. Time division duplex transmission scheme is used to realize full duplex transmission.
Now there is the latest technology 2.4G wireless keyboard and Wireless Gaming Mouse, what is 2.4G, it is actually a wireless transmission technology, 2.4G is on behalf of a data transmission rate, now on the market 2.4G wireless keyboard and mouse is a USB receiver, mini, general plugged in the computer, can be used directly.Bluetooth devices of any brand can be charged in up to three hours. You can usually power off by seeing the indicator on the keyboard change color or turn off. Charging a product for a long time can cause serious damage to it. If you're not using a wireless keyboard for a long time, it's best to charge your device once a month or so. In case its built-in battery goes dormant and cannot be recharged.
