Recently, Zhuhai City, announced a major energy-saving projects, before the end of 2013, more than 90,000 streetlights in Zhuhai City all transformed for the LED lights, and at the same time plans to build more than 7800 LED street lamps. Learn more about led downlight
LED lighting applications are of good quality with high scientific and technological content, low resources consumption, little environmental pollution from home lighting to extend the road lighting. Replace traditional street lights with LED lights, and do so not only Zhuhai City, in many places, including Suzhou, Changde, Chongqing, are underway in this regard a useful attempt.
Behind the impetus comes from the huge energy saving potential of LED road lighting. Held in the middle of this year, the United Nations Conference on Sustainable Development (“Rio +20″ Summit), an independent global climate organizations (The Climate Group) released test results show, LED road lighting can save up to 85% of energy. The data show that while the city life 70% of the world’s energy consumption, and 15% of energy consumption from lighting the road.
In addition to saving features of the LED lighting, road lighting intelligent control, energy-saving potential of LED road lighting will further release. This reporter has learned, Sinolumi Lighting in this respect innovative research to go in the forefront, its design Starsense & City Touch the city lights control platform, all light sources through wireless smart connect the central platform, which can these light sources conduct remote control, then according to a single light source to adjust the flow of people, traffic and weather changes in the actual situation. “These intelligent lighting system that can help us to detect pedestrians and vehicles on the road, if not, can the lights dim or turn off.” Said Sinolumi Group Research Institute senior vice president, Asia chief technology officer Dr. He Dana .

LED street lighting market potential is gradually released. According to statistics, in 2011, the domestic LED road lighting (including LED street and tunnel lights) output value of 35 billion yuan, the total output of 910,000. Street light output value of 2.9 billion yuan, the production of 680,000, the installed capacity of 530,000. LED tunnel light output value of 500 million yuan, and the production of 230,000, the installed capacity of 190,000. Market participants predict, LED street lamps in 2012 the output value is expected to account for 50% of the entire street market, the advance of urbanization will further stimulate the demand for LED street lighting.
Energy-efficient at the same time should also be more humane
Despite the energy-saving effect of LED street lighting has been recognized by the market, but also faced some criticism, including the lighting source is too bright, serious glare, the light is too intense glare. The end of 2011, the State General Administration of Quality Supervision, Inspection and Quarantine announced, road and street lighting quality passing rate was only 58.3%, LED road lighting overall quality of worrying.
To glare, for example, it will lead to eye fatigue, and produce discomfort. According to the researchers of the Sinolumi Lighting, glare Vision unfit brightness distribution, or extreme brightness contrast exists in space or time, causing visual discomfort and reduce the visibility of objects visual conditions. For example, when a bright spot in the dark field, the human eye is difficult to adapt and focus, will produce glare, which will lead to eye fatigue and discomfort.
With the gradual promotion of LED road lighting LED street lamp enterprises have begun to increasingly focus on standard applications with optical quality and visual comfort lighting demand factors more humane. How to overcome these shortcomings of LED lighting is particularly urgent. learn more about led ceiling light
Sinolumi Lighting research on how to overcome glare display, the color temperature of the light has a significant impact on people perceived degree of glare. People’s perception of the actual light output for the same, cause uncomfortable feeling of the low color temperature of the light (“warm white”) is less than a high color temperature of the light (“cool white”). One possible reason is that people of color temperature and light has its own preferences, and preferences in low light “warm white” (such as dawn, night and dusk), under high illumination preferences “cool white” (that is, the other day time ), a further reason may be that humanity has always regarded the “warm” color dusk / dawn linked to “cold” colors associated with daylight.
