Each 50W and 100W tunnel light uses 42 and 72 LUXEON Rebel LEDs, respectively. In addition to energy savings, these lamps have other advantages over traditional light sources such as fluorescent lamps, metal halides, and low-pressure and high-pressure nano lamps, such as a working life of more than 60,000 hours, impact and shock resistance, which greatly reduces replacement, maintenance, and personnel. Cost and lane closure time.
The use of LED technology in this project also includes other advantages, such as better color rendering, which improves driving visibility and safety; and because the heat generated by the LED is very low, the lamp is baked and accumulated by dust and dirt. The phenomenon of yellow light is also reduced; LED lights also have a number of "environmental" features, such as meeting ROHS requirements, the structure does not contain mercury and lead.
As one of the leading LED tunnel lighting manufacturers in China and one of the largest outdoor LED lighting products suppliers in China, Xi'an Liming works closely with Future Lighting Solutions' engineering team to ensure that the lamps produced meet the national tunnel lighting standards. At the same time, it has a sustainable LED supply. Future's services include LED components and color temperature selection, light simulation, lens testing, and advanced color temperature region subdivision to achieve the required color temperature of 5000K and provide joint inventory to ensure LED supply.
Mu Yijing, general manager of Xi'an Liming Company, said, “It is Fuchang’s help in designing and optimizing these tunnel luminaires that enabled us to meet and exceed the national standards for such luminaires and win these two Lighting contract for tunnel engineering. At present, we have many tunnel construction projects under planning. This engineering experience will help us to be in a favorable position in the bidding process of such projects."
Winter Chan, vice president of sales for Greater China, said, "This installation highlights the environmental and low maintenance cost advantages of using LUXEON LEDs for tunnel lighting, as well as the ability of LEDs to provide the brightness and balanced road lighting needed for safe and comfortable driving. The cooperation with Xi'an Liming on this project gives us the opportunity to participate in China's important infrastructure upgrades, and also gives us the opportunity to contribute to China's energy-saving initiatives."
TO-220 Transistor Outline Package is a type of in-line package often used in high-power transistors and small and medium-sized integrated circuits.
It not only plays the role of mounting, fixing, sealing, protecting the chip and enhancing the electrothermal performance, but also connects to the pins of the package shell with wires through the contacts on the chip, and these pins pass through the wires on the printed circuit board. Connect with other devices to realize the connection between the internal chip and the external circuit.Because the chip must be isolated from the outside world to prevent impurities in the air from corroding the chip circuit and causing electrical performance degradation. On the other hand, the packaged chip is also easier to install and transport.
TO-220 package is a kind of in-line package that is often used for fast recovery diodes. TO-220AC represents a single tube with only two pins and only one chip inside.
The diodes are packaged in TO-220AC and can be used in switch mode power supplies (SMPS), power factor correction (PFC), engine drives, photovoltaic inverters, uninterruptible power supplies, wind engines, train traction systems, electric vehicles and other fields.
