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

Announce this year's Nobel prize in physics, let Blu ray LED technology once again become the focus, and this technology has been widely used in Suzhou city lighting.

In September this year, more than 3700 sets of LED lamps are installed on the southeast Ring Interchange 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, the Blu ray LED technology and the lives of ordinary people closer, it can exist in the camera and lighting, and mobile phone. 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 Sioux City Landscape Lighting

The world's first commercial LED in 1965 successfully developed in Suzhou, large quantities of LED for municipal facilities is more than 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. At present, urban landscape lighting, in addition to a small amount of floodlights also use halogen lamp or high-pressure sodium lamp, almost all of the use of the 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." Chief of city lighting management department Zhu Jihong introduced technical quality.

Because of the advantages of LED technology, from the beginning of 2013, all residential district of Suzhou street lighting was gradually replaced by LED, has completed the replacement work of about 70%.

Light penetration rate as the high price of landscape lighting specifications are not unified into the "bottleneck"

Compared with the commonly used LED landscape lighting lamps, LED lighting in the road in the field is still in the demonstration, try to gradually promote the use of the transition stage.

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 lights. In September this year, more than 3700 sets of LED guardrail lamp installation still the southeast ring interchange ramp, not only the illumination protection, beautiful appearance, but also to avoid the glare and stroboscopic etc..

Why is the popularity of LED technology of the street lamp is far less than the rate 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."

There are hundreds of LED lighting production enterprises in Suzhou

LED lighting technology has been recognized as the national efficient lighting industry has the most potential for development, after being called following the incandescent lamp, fluorescent lamp and high-pressure gas discharge lamp, and a revolution in lighting field. In addition to city lighting, automotive lighting, traffic signals, multimedia imaging, optical fiber communication and other fields has been widely used in LED technology. For example, automotive lighting, general use of original halogen lamps, the lumens at about 40LM, now some cars have begun to use LED lamp lumens can reach 120LM. At present, the Suzhou production of LED lamp size has hundreds of companies.
