LED popularity of Suzhou urban landscape lighting accounted for more than 90%

This year's Nobel prize for physics announced, so Blu ray LED technology once again become the focus, and this technology has been widely used in urban lighting in Suzhou.

In September this year, more than 3700 sets of LED lamps installed on the ramp ramp

The 2014 Nobel prize in physics awarded to three scientists from the United States and Japan: Akasaki Yong, Amano Hao and in the village of two, for their invention of the blue light emitting diode (LED), and thus bring new energy-saving light source.

Compared with the previous Nobel prize in physics, Blu ray LED technology and the lives of ordinary people closer, it can be lighting, and there are cameras and mobile phones. In Suzhou, more than 90% of the landscape lighting from LED technology; Suzhou District primary and secondary roads on more than 2500 street lamp using LED lamps; in addition, all residential district of Suzhou street lighting will be gradually replaced by LED.

Large quantities of municipal facilities for LED lighting technology Su city landscape

The world's first commercial LED was successfully developed in 1965, and in Suzhou, a large amount of LED used in municipal facilities is more than and 40 years later.

In 2008, Suzhou launched the first ring landscape renovation of the ancient town of river, LED began to replace the original lamp lamp, guardrail lamp using halogen lamp light source; in 2009, urban building landscape lighting began to change LED light source; since then, new buildings, landscape lighting and other basic facilities all use LED lighting technology. Currently, the urban landscape lighting, in addition to a small amount of floodlights also use halogen lamps or high pressure sodium lamp, almost all of the use of LED lamps, accounting for more than 90%.

"Now, LED lighting in landscape lighting applications has been very popular, in addition to part of the need for carrier floodlight lighting, in parks, green space, square, building and city viaduct and other small and medium-sized power landscape lighting places, because the LED rich colors, in theory only can completely cover the CIE color in all color saturation curve using LED light source, and a variety of colors of LED by mixed light and organic integration and fluorescent powder, can produce almost any color without limit at the same time, the flexible control, convenient adjustment, small volume, very obvious advantages. "City Urban Lighting Management Department of technical quality section chief Zhu Jihong introduction.

Due to the obvious advantages of LED technology, from the beginning of 2013, Suzhou District, all residential street lighting is also slowly replaced by LED, has now completed 70% of the replacement work.

Street lighting penetration rate is not as high as the landscape lighting specifications are not unified into a bottleneck"

Compared with the general use of landscape lighting LED lamps, LED in the field of road lighting is still in the demonstration, to try to gradually promote the application of the transition phase.

From the beginning of 2007, Suzhou City Lighting Management in small manufacturers of LED products began the trial area part of branch; in 2009, Pingjiang New Town Road Jiang first pilot installation of 10 LED lights, and tracking test. At present, Suzhou District has nearly 30 roads installed nearly 2500 LED street lamp. In September this year, the Department also installed more than 3700 sets of LED guardrail lights on the southeast ring ramp ramp, not only the lighting is guaranteed, beautiful and generous, but also to avoid the stroboscopic, glare and other shortcomings.

Why LED technology in the popularity of street lighting is far less than landscape lighting it?

Zhu Jihong, this is the current defects caused by the LED lamp, "only from the light efficiency and energy saving, high pressure sodium lamp LED products are now widely used on the road and the city has close lumens each watt (lumens of luminous flux unit. The luminous intensity of 1 candela point light, luminous flux emitted in the unit solid angle is 1 lumens, English abbreviated as LM) were more than 120LM, but the relative price of traditional LED lighting lamp or high energy, not necessarily money "; in addition, the current state of the LED lamp module and the standard is not unified standard, so the product specifications of the manufacturers are inconsistent, resulting in the maintenance of LED street lamp, it is difficult to replace the light source in the field, and even the need to return to supplier maintenance is very inconvenient. "

LED lighting manufacturers have hundreds of Suzhou

LED lighting technology has been recognized as the most potential for the development of efficient lighting industry, known as incandescent lamp, fluorescent lamp and high pressure gas discharge lamp, the lighting of the field after another revolution. In addition to urban lighting, automotive lighting, traffic signals, multimedia imaging, optical communications and other fields have been widely used LED technology. For example, car lighting, the original use of halogen lamps, the lumen is about 40LM or so, and now some cars have begun to use LED lamps, lumens can reach 120LM. At present, the size of the production of LED lamps in Suzhou enterprises have hundreds.
