Beijing subway 6 months within the platform for LED lights can be saved in the province 1 million kwh

Beijing subway will be in 6 subway stations and the interval between the platform for LED lighting system transformation, this transformation is expected to save electricity for the Beijing subway every year 1 million degrees. Is expected this year, this energy-saving lighting system will be fully opened in an existing line.

More than 7000 energy-saving lamp posts the end of the month

Beijing subway introduction of energy saving housekeeper to participate in the transformation. "Energy conservation housekeeper," the scientific name is called contract energy management (EMC), is a new market-oriented energy-saving mechanism. Its essence is to reduce energy costs to pay the full cost of energy saving projects. Beijing subway official explained, energy management contract not to sell a product or technology, EMC's operating mechanism is a kind of energy-saving investment service management; customer saw energy efficiency, EMC company together with customers to share such results, achieve win-win results.

In accordance with the "energy manager" planning, the LED lighting renovation project of Beijing Metro Line 1 Wanshou Road station to Gongzhufen station, China World Trade Center station, and Gongzhufen to Wanshou Road range, line 2 Jishuitan station to Xizhimen range, and the Jishuitan No. 5 line Lishuiqiao station, line 13 Xizhimen station, a total replacement of different specifications of lamps more than 7000 branches, is expected to be completed at the end of May.

LED lamp power saving 40%

These lamps are mainly concentrated in the public area of the station hall and platform level. After the transformation, the passengers did not feel obvious when riding the subway. Beijing Metro electrical company official said, the replacement of energy-saving lamps will not change the light, fully in line with lighting standards, but because it is a new device, and sometimes passengers will feel more transparent station. "

Last year, once in the Beijing Metro Line 5 Beixinqiao station, line No. 2 Chegongzhuang station and 3 stations and Media College Station, Batong Line No. 2 Chegongzhuang Fuchengmen section within the range of the pilot LED green lighting. Then, the subway station 1 3 electromechanical company for the interval are summarized, and through the field test, data analysis, a factory visit seminar, the basic grasp of LED products in the actual operation of the subway and the current level of development of the industry. Accordingly, the Beijing subway identified 6 stations this year, the technical requirements of the 2 interval LED content, is expected to be able to save about 1 million degrees per year after the transformation, saving rate of more than 40%.

In addition to the subway station in the use of low energy lamps, 2015 years ago, the green light will be on the subway train, and in some vehicles to promote the use of paragraph.

Currently, the pilot has been carried out in line 1. These installed in the car on the LED lamp price of about 300 yuan, equivalent to an ordinary fluorescent lamp 50 times, is expected to train a total cost of up to $50 thousand renovation. However, due to the reduction in electricity consumption, reduced maintenance costs, about three years to recover the cost.

Beijing subway trains run an average of 12 hours a day, ordinary fluorescent lamp life is generally about 500 days, but due to some external factors, these lights are often 'strike', so a year on the train lighting up to 10000 yuan. Metro Company official said, the replacement of the LED lamps strong earthquake resistance, six or seven years without replacement.
