British researchers are now actively cooperate with enterprises, hoping to develop a light-emitting diode (LED) technology that is used in road lighting as the best solution to develop more durable, low-power road lighting equipment. |
According to British media reports, University of Manchester located in the north of England is now working with the LED lighting company DialightLumidrives cooperation.the researchers from the School of Electrical and Electronic Engineering are studying how to make a group of LED that is tightly packed together safely and reliably work.. Scientists said that if provided with LED lighting, energy consumption can be reduced by 25% to 50%. But when you need 12,000 lumens (a typical 60 watt household light is 800 lumens) or more of the lighting, heating and other electricity-related issues will be obstacles that is using LED technology. Engineers will also face with some practical problems, such as heat generated by a group of the LED that is tightly packed together . Since the LED module will be used in the outdoors, so it is necessary to consider the actual environmental factors, such as the possibilities is that critical heat sink is nested by birds.
Dr. RogerShuttleworth working in power conversion unit of Manchester University said: “light-emitting diode technology was first demonstrated its excellence in the 1970s appliance display, and then we see more and more light-emitting diodes are used in areas such as the LED tunnel light and LED road light as traffic lights and cars light on such things. “he said,” In the 20th century, so that old-fashioned orange sodium high pressure sodium lights which make all objects appear radiate gradually being replaced by these high-pressure sodium that glow brighter, and are consistent with the visual aesthetic, but also help solve street crime and antisocial behavior, and low energy consumption. “He added,” With environmental issues are referred to prime location of the state and government agenda, energy saving has become an important issue, if you know how many lights there are in the UK, you will know how much opportunity that savings on energy and cost. “
Although, high pressure sodium vapor lamps that is very popular consumed per watt in Europe, can produce 85 lumens of illumination level, but experts believe that LED technology has made that the amount of lumens is more than 150 generated by per watt electricity, and with the emergence of new semiconductors, expects this figure will increase. The researchers said that LED street lights also help reduce light pollution,while reducing energy consumption and overall operating costs ,it may be the past that the large cities issue heat to the sky.
The long-life of the LED street lights do not need frequent replacement, thereby reducing the potential for traffic disruption, reducing maintenance costs for this payment. Manchester University has researched the life of LED street light module for more than 10 years, which is more than four times than the life of the ordinary street. Under normal operation, LED street light must go through the process of gradual reduction output, and this process continues. What causes decrease in light output may be due to lower efficiency of light generated by the LED, or the diameter of the light reduce in the LED compressed. However, as long as no overload, LED street lights can work for 50,000 hours or 10 years and can also reach 70 percent of output capability of the original light. However, it is not as important as it sounds, generally speaking, the human eye is not sensitive to changes in light output, only obviously feel when the reduction is 50% . It is reported that the one-year plan has gotten the British government £ 175,000 funding, Dialigh company also provides the same amount of money. A major goal is to develop a highly reliable, low-cost lighting solutions. Lead lighting with professional R & D and production teams specialize in providing more energy saving LED tunnel lights, LED road lights high that have waterproof, dustproof, shockproof, good heat dissipation character so that close to the road and tunnel environment, access tunnel lights’ web www.lead-lighting.com/products/bid32-1.htm can log more Multi-LED tunnel lights, or return home browse street lamps’ web. Related Background: LED LED was first introduced and appeared in digital watches and computer in the 1970s. Today, the technology has made considerable progress and can be used to make durable, low energy consumption and community-friendly road lighting equipment,such as LED street light and LED tunnel light. The expectancy life of the LED light is long (up to 100,000 hours), gradually increased high light output depending on the model size and energy consumption rate, the LED can be used instead of the traditional sodium vapor cell for general lighting and lights. Moreover, the LED volume is so small, so it is just used to create a more sleek styling, smaller, lighter luminous body. However, the most important thing is that LED is very environmentally friendly and safe. It does not contain glass, filament or mercury, it does not occur explosion due to the high current halogen. Meanwhile, LED cost low, it does not limit mercury processing sodium vapor cell brought about. Low voltage direct current operation can completely guarantee the safety of consumers. Color LED module can make that the color is very realistic, but also more energy unit effectiveness than the incandescent.
