2009 road lighting energy into the theme of LED into the protagonist

Chengdu two tunnel pilot with energy saving electricity tariff down by 50%

Mr. Zhang often drove through the star road tunnel have been wondering: color light tunnel two road side is white, one is yellow, this is why? Chengdu City Drainage Department official told the author that the tunnel began in the energy saving light compared experiment from last year, from the south to the north of white light tunnel the roof is energy-saving lamps, energy saving rate of 50%. The official said, the next step in the city under the 19 tunnel and the loop is expected to promote the three energy-saving lamps.

Two tunnel pilot energy up to 50%

In addition to Hongxing Road Tunnel, Shuinian tunnel from south to north to the channel at the end of January last year were also "energy-saving lamps" transformation. Jinjiang District Electricity Supply Bureau charge details show that in January last year, the tunnel electricity expenditure 11513 yuan, in February, $11524, in March dropped to 6259 yuan, in April, $8004. Municipal drainage facilities at the user trial also shows that this lamp energy saving rate of 50%. "

Responsible for the transformation of the tunnel lighting enterprises responsible person, the scientific name of this energy-saving lamp called high frequency electrodeless fluorescent lamp, 100 watts per lamp. Compared to the current 250 Watt High pressure sodium lamp, the same number of lamps can provide better lighting conditions. Moreover, the service life of high-pressure sodium lamp is only 1 years, less than the energy saving lamp life of about 5 years. Calculation of tunnel data in Hongxing Road and Shuinian he: 19 seat city tunnel if all transformation, the annual saving about 2000000 degrees, saving electricity about 1600000 yuan.

Replaced with energy-saving lamps, "how are you Chengdu people? Is the master Liu Hongxing Road near a company driver, when he felt the weather generally two road almost, but if the light outside is very strong, sunny, energy-saving lamps advantage is obvious, because the white light closer to natural light, just enter when won't appear all of a sudden the eye feels uncomfortable".

19 under the tunnel and three rings is expected to promote

However, the transformation of the initial investment is not a small expenditure pen. The above two tunnels, for example, together with lamps and a full set of installation services, a total investment of more than 500 thousand yuan. To this end, the transformation of the company proposed the use of contract energy management mode (EMC), the company provides products and services, all costs from the annual payment of electricity saving.

It is understood that the Chengdu Municipal Economic Commission submitted earlier proposed a municipal government to consult the report, if the 19 seat municipal tunnel under all of the use of high frequency electrodeless fluorescent lamp, two years of savings in electricity can recover the full investment. The report also suggested that the municipal government, the first 19 in the city under the tunnel, the loop of the pilot, and strive to promote the application of the full range of 3 years within three years.

Chengdu City Drainage Department official said, the next step will be through the tunnel in Red Star Road and Shuinian tunnel under the other half, and the root of the tunnel under the Dongcheng promote pilot energy-saving lamps.

MTR to promote the full use of LED lighting system

LED light pipe with high energy efficiency is becoming more and more popular, in addition to the popularity of LED TV, Hongkong Mtr Corporation started this week, in a line of Tsuen Wan line using LED lighting system. The LED lighting system saves 30% energy compared to the traditional light pipe, life expectancy is also more than the general light pipe durability of three times. MTR said that the new lighting system will not only save energy, but also to achieve environmental protection purposes, depending on the passenger reaction, considering the promotion to full use.

It is understood that Mtr Corporation invested 4 million yuan, in the installation of the environmental protection of the installation of the 3 trains, using high brightness LED. 3 Hong Kong MTR trains will be installed by the 64 high brightness LED chip lighting devices, one of which will be put into service this week in Tsuen Wan line, the remaining two in June 2009 before the service. MTR will also be at the rainbow station, testing the new lighting system, in the station for daily lighting purposes, the project is expected to be completed by August. At present, more than 100 trains will be put into service, and the MTR will test the new lighting system for two years, depending on the passenger 's response and technical feasibility. Hong Kong University Science & Technology electronic calculator and engineering professor Chen Zhenghao is responsible for the research of the new system, new and improved high brightness LED is expected to use only 70% of the traditional power tube, namely 30% energy saving life up to 50 thousand hours, 3 times more durable than the general light tube, in addition, when a high brightness LED chip failure instead, just replace the chip, reduce waste, to achieve environmental benefits.

Fuzhou main road traffic lights with bright LED lights

All the traffic lights in the main road of Fuzhou will be updated to a LED signal lamp with a diameter of 400 mm. The author in February 14th from the city Traffic and patrol police detachment was informed of another good news in the future, the new expansion, road reconstruction, construction of road and traffic facilities will ensure synchronization in place, traffic lights, signs and markings and road construction simultaneously, road repair can be opened to use immediately.

According to reports, the traffic lights in the main city of Fuzhou has been basically realized the LED, and now is part of the original diameter of only 300 mm expansion, to achieve all the up to 400 mm.

LED traffic lights are characterized by: energy saving, long service life, brighter and more eye-catching. In addition, there is a very important feature is LED, unlike ordinary incandescent lamp, even one bulb is broken, the lamp body still has little effect -- only a small black spots appear in the light of central, but local spots, does not affect the use of the red lights.

At present, in the road construction, city police detachment and the City Construction Bureau
