Lighting Science Group Corporation (LSG) , a global leader in LED (light emitting diode) lighting products, introduces its new line of LED roadway luminaires. The new PROLIFIC Series Roadway Luminaires have substantially increased light efficacy when compared to traditional lighting technologies such as high Intensity discharge (HID) and significant better light efficacy when compared to currently available LED based street lights.
The new Lighting Science line of roadway fixtures perform between 80 to almost 90 lumens per watt depending on the model. This performance was validated by an independent testing laboratory that is approved for LM-79 Testing for ENERGY STAR for solid state lighting by the United States At over 80 lumens per watt, the LSG PROLIFIC series delivers industry leading performance over currently available LED based street lights offering only 50 to 60 lumens per watt efficacy. With over 40 million streetlights in the US, these new products Have the potential to dramatic expand the market for LED roadway lighting technology and revolutionize the way roads, streets and highways are illuminated.
The PROLIFIC Series Roadway Luminaires provide replacement for existing high intensity discharge (HID) lighting installations for highways, city and residential streets, college campuses, government facilities, parking facilities and commercial projects. Four versions of the PROLIFIC luminaires, LSR1 at 50 watts through LSR4 At 150 watts, are available to replace 100 watt to 250 watt HID cobra head fixtures. Designed to deliver high quality illumination combined with energy efficient LED technology, the LSG roadway luminaires provide superior optical performance and maximized pole spacing. By using an internal thermal management The system integrates custom arrayed optics and uses recyclable, corrosion resistant materials.
What is Industrial DTU? Industrial DTU characteristics and application field analysis
What is DTU?
A Data Transfer unit (DTU) is a wireless terminal device that converts serial port data into IP data or IP data into serial port data over a wireless communication network.
Second, industrial DTU characteristics?
D220 is an industrial 4G DTU based on 4G wireless network, the product uses high-performance industrial embedded processor, real-time operating system as the software support platform, to ensure that the data link is smooth at any time, to provide users with high-speed, stable and reliable data transmission. It can be easily and quickly arranged in the industrial site, and can be used in harsh environments.
