City lighting all adopt LED light source can save nearly 70%

Every night, Harbin Jingwei street and Jihong Street Interchange four green in the "colorful maple hodginsii scenic spot", "fireworks", the square of Songhua River highway bridge "double green plum Ao scenic area and scenic spot lighting lights, colorful. Residents and visitors to appreciate the magnificent lights at the same time, can not help but ask, these lamps a year of electricity to how much money? Reporter learned from relevant departments, all of the landscape lighting Harbin this year using LED light source, compared with the ordinary electric lantern festival in previous years nearly 70%.

Adopts energy-saving light source lighting landscape

Reporter from the Harbin city comprehensive environmental remediation office to understand, in the lighting lighting process this year, in addition to building generalization lighting lighting, landscape lighting at more than and 200 100% in Harbin and two or three kinds of Main Street on the street by LED energy saving energy saving environmental protection lamp. Harbin use LED basic time with the world, the national synchronization. Just completed the Beijing Olympic venues "Water Cube" is the use of LED lighting.

For this year's lights king, tourists and citizens are much appreciated, generally believe that this year's lighting lighting color more saturated, more beautiful. Who lives near the Daoli District Highway Bridge in the street near the uncle said that in previous years, just around the tree lights, and this year the branches as if out of a bunch of flowers, especially lifelike.

Beautiful landscape lighting for many visitors to Harbin can not help but watch the night scene of Harbin taxi. The taxi driver Qu Zheng Sanwei company told reporters, because now is the tourist season, every day he will pull a few specially to see the night view of Harbin tourists, visitors talk is the most advanced LED energy-saving lamp.

Power savings of nearly 70%

According to the Harbin city comprehensive environmental remediation office lighting lighting department director Liu Baiyun, according to the theory of the LED lighting power saving of nearly 70% compared with the previous ordinary lamp. Since this year is the first year of use, is still unable to calculate the actual electricity consumption, conservative estimates can save at least 1/3 of electricity.

Liu Baiyun said, LED is the semiconductor lighting English, the semiconductor light emitting diode belongs to the fourth generation light source. Under the same brightness, the power consumption of the semiconductor lamp is only 1 / 10 of the incandescent lamp, and the power conversion is close to 100%, and the service life is longer than the traditional light source by more than 10 times.

Liu Baiyun in the most common landscape "stars" lighting for example, he said, a bunch of "stars" of 100 light bulbs, ordinary lamp before is 70 watts, now with LED lights only 7 watts, the decoration of a street with thousands of "stars" string, and use the entire Harbin "stars" was staggering, the energy-saving benefit is also very amazing. According to conservative estimates, from December 2007 to the end of the Lantern Festival, Harbin street landscape of electricity at least 1/3.

It is understood that this year's Harbin world ice and snow and ice garden scenic part will also use LED lighting. According to statistics, only Harbin Zhaolin Park you Yuanhui year landscape lighting electricity power reached 3000 to 3400 kilowatts, each night lighting time in 5 - 6 hours of electricity each year to spend more than 60 yuan. If the use of semiconductor lighting products to replace the existing ordinary fluorescent lamps, saving more than 50%. Organization of the provincial science and Technology Department of high-tech office to implement icescape Zhaolin Park LED lighting demonstration project, the "happy stage" landscape was calculated, using LED light source than 64% energy-saving fluorescent lamp.

After two years is expected to enter people's homes

High tech development of Heilongjiang Provincial Department of science and technology and industry department chief Zhou Hao said, the Harbin Street on the road more common "stars" lighting most of the landscape trees, belongs to the small power LED lamp, in recent years, with the rapid development of Harbin LED industry, small power LED lights the production cost decreased gradually, and power saving, not easy to damage, durable, reusable and other advantages, now the application of LED lighting landscape lighting in Harbin city is very wide.

Chief Zhou Hao also said that although the luminous efficiency of white light LED in the proportion of 20% annual increase in production costs, decreased by 10%, but let LED white light into the home, used in indoor lighting, the cost is relatively high, it is difficult to achieve. Now the provincial science and technology department have already started the experiment application in Harbin, and for the development and improvement of the white LED lamp, LED light source is expected after two years into people's homes.
