Intelligent lighting into the field of metro line four Guangzhou power saving of 490 thousand degrees

Recently, Guangzhou residents take the line four train, will be found in the elevated line, if the car better weather, illumination will reduce the car, when the train enters a tunnel, the lighting brightness will automatically and quickly return to their normal state. Reporters learned that the four line of the car to achieve the transformation of intelligent lighting control.

According to the subway company, the project for the Guangzhou metro for the first time in the vehicle compartment illumination application of intelligent control technology, through the two sides of the compartment LED lamp with diagonal installed illuminance sensing controller will automatically regulate the illumination. When the illuminance of the car is high, the power output is reduced, and the output power is increased when the light intensity is low. When the train line at the high line and sunny outside the car, room illumination controller will automatically reduce the lighting power even close lighting, instead of using train external sun light lighting, reduce energy consumption. It is reported that the first train had transformed lighting system running on the line, line four of the remaining 29 train at the end of the year will be completed before the transformation, after the use of the technology is expected to save electricity 490 thousand degrees, equivalent to about 410 thousand yuan.
