LED universal landscape lighting Suzhou urban area accounted for more than 90%

The announcement of the Nobel prize for physics this year has added to the focus of Blu ray LED technology, which has been widely used in urban lighting in Suzhou.

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

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 for physics, Blu ray LED technology is closer to the average person's life, it can be illuminated and stored in cameras and cell 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 used in municipal facilities, LED technology, lit Su city landscape

The world's first commercial LED was developed in 1965, while in Suzhou, large quantities of LED are used in municipal facilities after more than 40 years.

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. At present, the urban landscape lighting, in addition to a small amount of floodlights, but also the use of halogen lamps or high-pressure sodium lamp, almost all used 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 lighting management division technology quality section chief Zhu Jihong introduction.

Because of the obvious advantages of LED technology, from 2013, the street lighting of all the districts in Suzhou District has also been replaced by LED. Now, about 70% of the lights have been replaced.

The popularity rate of street lighting is not as high as that of landscape lighting, and the specifications are not unified as "bottleneck""

Compared with landscape lighting, LED lamps are widely used in the field of road lighting. LED is still in the transition period from demonstration and try to gradually popularize and apply it.

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 lamps. In September this year, it is also installed on the southeast ring ramp more than 3700 sets of LED guardrail lights, not only lighting protection, handsome appearance, but also to avoid the stroboscopic, glare and other shortcomings.

Why is the popularization rate of LED technology on street lamps far less than that of landscape lighting?

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 lamps manufacturing enterprises in Suzhou have hundreds

LED lighting technology has been recognized by all countries as the most potential highly effective lighting industry. It has been called "second revolution" after the incandescent lamp, fluorescent lamp and high-pressure gas discharge lamp. Besides urban lighting, LED technology has been widely used in many fields, such as automobile lighting, traffic signal, multimedia display and optical fiber communication. For example, car lighting, the original general use of halogen lamps, its lumen is about 40LM, and now some cars have begun to use LED lamps, lumens can reach 120LM. At present, the production of LED lamps and lanterns in Suzhou has hundreds of enterprises.
