14 subway stations in Guangzhou with 7527 sets of LED lamps annual saving 2 million 450 thousand

Nanfang Daily News, July 15th, the Guangzhou city subway bulletin said, the Sanyuanli metro line two to Pazhou period lasted nearly 2 years (excluding Xiaogang, Chigang Station) LED energy-saving lighting demonstration project has recently been completed, 14 subway stations in the public area of general lighting systems were replaced by 7527 sets of LED lamps, lighting the whole station the evenness is before the transformation of nearly 10%, an annual electricity up to 2 million 450 thousand degrees. Guangzhou Metro said, taking into account the effect of energy saving and environmental protection LED better, since the line six phase after all the new lines, general lighting in the public area of the station was designed by the LED lamp, and the old line, part of the station of line 1 and the line four train is currently being carried out LED light transformation, the rest of the line to the original lamp life expires after the change in succession.

LED lamp energy saving and longer life

In the old Guangzhou subway line early, the public area of the station's general lighting is mainly used in the common fluorescent lamp, and with the development of semiconductor lighting in the world in recent years, LED lamps came into being. According to experts, in the same brightness, the LED lamp power consumption of only ordinary fluorescent lamp 1/2, and life can be prolonged 5 times. More importantly, the LED light source itself does not contain harmful substances such as mercury and lead, LED lamp infrared and ultraviolet harm is far less than traditional fluorescent lamps, no infrared and ultraviolet pollution, can not produce the external pollution in production and use.

In 2010 by the Guangzhou municipal government and the national semiconductor industry technology alliance investigation recommended, Guangzhou Metro Corporation take the Taiwan Affairs Office of cross-strait economic and trade cooperation in cross-strait cooperation projects - Guangzhou Metro semiconductor lighting demonstration project, taking into account the original lamp station of line two has reached the replacement period, in the original two line 14 subway station public implementation of energy-saving LED lighting demonstration project, for future subway large-scale installation and use with LED pilot lamps".

An annual capacity of about 2 million 450 thousand degrees

Guangzhou Metro said that the implementation of the project time is very tight, every day can only arrange the construction in subway outage period, after deducting the necessary operation time, every valid time of the actual construction of up to 3.5 hours, even with some special operational arrangements for the effective time is significantly shortened. In order to ensure the smooth progress of the project, the subway company organization design, contractors, operators, suppliers of each station by station for detailed exploration, lighting lighting design scheme evaluation through simulation, fine adjustment to the existing national standards, establish product consistency tracking mechanism of the entire project, finally lasted nearly two years, completed in March 2015, July 15, 2015 the unit project acceptance.

In using the overall performance to meet and exceed the expected level which lasted nearly two years of renovation project. According to the subway company, engineering a total removal of 8790 sets of fluorescent lamps, LED lamps installed 7527 sets, the total number of lamps is reduced by 14.4%. The project is put into use, the third party testing project, lighting energy saving rate up to 48.8%, the annual saving of about 2 million 450 thousand degrees, the energy saving effect is remarkable. Not only that, after the implementation of the project, the station platform, the station hall overall illumination uniformity is increased by nearly 10% in 2014, the Guangzhou subway passenger satisfaction survey, ticket hall, channel and platform bright degree of satisfaction of 9.10 points, the passengers are satisfied with subway station lighting.

General lighting in public areas with new LED lamps

The reporter learned that, in the current global context of energy shortage, energy conservation is an important problem that we face in the future. The MTR as city public transportation, the lighting electricity load as an important electricity accounted for about 8-10%. The use of green lighting technologies such as LED, will greatly reduce lighting electricity consumption, and can reduce the cost of equipment maintenance, so as to effectively reduce operating costs.

Guangzhou Metro said that the implementation of the project has achieved good results, greatly promote the application of LED industry in the city rail transportation and other important engineering fields. Therefore, since all new line line six phase began, general lighting in the public area of the station adopts the LED lamp, and the old line, part of the station of line 1 and the line four train is currently being carried out LED light transformation, the rest of the line to the original lamp of replacement period after the change in succession.
