Chengdu, the pilot used the tunnel down five electricity into energy-saving lamps
Red Road to drive through the tunnel, Mr. Chang has been very puzzled: Tunnel Road, the lights of two colors one side is white, one side is yellow, this is why? Chengdu Drainage Department official told the author, the tunnel started last year Comparative test for energy-saving lighting,menu boards, from south to north the tunnel roof, white lights are energy-saving lamps, energy-saving rate of up to 50%. The official said the next step, Block 19, of Tunnel City, and the Third Ring Road is expected to promote this energy saving lamp.
The two tunnels into the pilot energy-saving up to five
In addition to Red Road tunnels, Shuinianhe tunnel below the channel from south to north to the end of January last year, also the Jinjiang collect details Electricity Supply Bureau show that in January last year, electricity costs 11,513 yuan of the tunnel, 11,524 yuan in February, March plunged to 6,259 yuan, 8,004 yuan in April. City drainage facilities at the Transformation of the tunnel lighting business person in charge, this energy-saving lamp of learning called 250 watts compared to now use high-pressure sodium lamps, the same number of lamps to provide better lighting conditions. Also, high pressure sodium lamp life of only 1 more than a year, saving lamp life less than 5 years. to Red Road and Shuinianhe tunnel below the data: City Tunnel under 19 if all the transformation, the annual saving of more than 200 million degrees, more than 160 million electricity savings.
Replaced with energy-saving lamps, White light is closer to natural light, just entering the eye does not occur when all of a sudden not suited to the feeling.
19 and the tunnel below the ring is expected to promote
However, lamps transformation is not a small initial investment expenditure. is still an example of the two tunnel below, along with lamps and a full installation service, a total of more than 50 million invested. To this end, transformation of enterprises proposed mode of operation using energy management contract (EMC), the company provides products and services, all costs from electricity savings in the year paid.
It is understood that the municipal government of Chengdu Economic Commission to submit early to consult a report suggested that if the 19 municipalities all using the tunnel below the high-frequency electrodeless fluorescent lamps, electricity can be saved for two years to recover the full cost of inputs. The report also suggested the municipal government, the first Block 19 in the tunnel below the city, the three loop pilot, and strive to fully promote the use of 3 years.
Chengdu Drainage Department official said the next step, will tunnel below the Red Road and Shuinianhe another tunnel below the half-size,food signs, and the Dongcheng Gen tunnel below the extension of the pilot energy-saving lamps.
MTR to promote their use of LED lighting systems across the board
With high energy efficient LED light pipe increasingly popular concept of welcome, in addition to the growing popularity of LED TV, the Hong Kong MTR Corporation by the beginning of this week, in a Tsuen Wan Line trains to use LED lighting system. The LED lighting system than the traditional three to energy saving fluorescent tubes, fluorescent tubes than the average life expectancy three times as durable. MTR, said the new lighting system will not only save energy,catering menu, and to achieve environmental objectives will depend on passenger response, extended to consider the full range of use.
It is understood that the Corporation spent 400 million, in the three MTR trains green lighting installation, the use of high-brightness LED. 3 列 MTR trains will be installed by the 64 high brightness LED chips lighting device in which a train will this week put into service within the Tsuen Wan Line, and the remaining two in 2009, put into service before June. Choi Hung MTR station will also test a new lighting system, lighting in the station for daily use, works are expected to be completed in August. MTR now has more than 100 trains in service, the MTR will be testing new lighting system for two years and, depending on the reaction of passengers and technical feasibility, and then consider the full range of implementation. Hong Kong to study the new system of Electronic and Computer Engineering Professor Chen Zhenghao said the new improved high-brightness LED is expected to simply use the traditional fluorescent tubes Qicheng electricity, a savings of 30% of the energy, life up to 5 million hours of fluorescent tubes and durable than the average 3 times the other hand, when a high-brightness LED chip fails, simply replace the chip, instead, to increase waste reduction, to achieve environmental benefits.
Fuzhou main road traffic lights, bright LED lights with wide
Fuzhou trunk updated all the traffic lights will come with a diameter of 400 mm LED lights. I February 14 Patrol Detachment from the city also learned another good news, the next new, expansion or alteration to existing roads, will ensure that road construction and transport facilities in place simultaneously, the associated traffic lights, signs and markings are and parallel road construction, road repaired immediately be opened to use.
According to introduction, the main road in Fuzhou City in fact has basically realized the traffic light
LED traffic lights is characterized by: energy saving, long life, brighter more visible. In addition, there is a very important feature, LED unlike ordinary incandescent lamp, even if one bulb is broken, the whole body is still little effect on light - appeared only in the light of a small black spot center, but only local black spots, does not affect the use of the traffic lights.
Current road construction, the City Patrol Detachment with the City Construction Bureau is one of construction, and acceptance of, and put into use.
