14 underground garages in Jinnan campus of Japan have completed the smart lighting system transformation project. While improving the lighting experience, the transformed garage lighting system can save 220000 kwh of electricity every year, save 115000 yuan of electricity expenses, and the energy saving rate is up to 65%.
According to reports, Jinnan campus in Japan has 4 underground motor garages and 10 underground bicycle garages. Before the renovation, 1800 36W traditional fluorescent lamps were installed. Because the original manual switch lamp is difficult to carry out fine manual management, the garage has to turn on the "constant light" from morning to night, and the annual power consumption is nearly 500000 kwh. Although the staff strengthen the energy-saving management and adopt the mode of interval lighting, it still needs to consume 340000 kwh / year, and the electricity cost is 176800 yuan / year. In addition, the underground garage is humid in summer, and the fluorescent lamps are easy to be damaged by dampness, so the school needs to spend a lot of manpower, material resources and financial resources every year to maintain the daily operation of the garage lighting system.
In order to solve the problems of large energy consumption and high maintenance cost of underground garage lighting system, and realize further refined management, Japan logistics support department recently carried out energy-saving transformation of lighting system in 14 underground garages of Jinnan campus in accordance with the principle of "low carbon and energy saving".
Through scheme comparison and selection, the logistics support department of Japan finally adopted the transformation scheme of "lighting LED + intelligent control system". According to the plan, after the calculation of light efficiency and the experimental measurement of on-site road illumination, 18W LED lamps are adopted in the garage after the renovation to replace 36W traditional fluorescent lamps before the renovation, the power consumption is reduced by half, but the illumination can be improved; After the transformation, the garage adopts the control mode of "front-end mobile sensor + intelligent gateway + back-end cloud platform management", which can timely monitor the traffic between people and vehicles, and link the light controller to intelligently adjust the brightness of lamps; After the transformation, the garage is integrated with a single lamp intelligent control system, which can independently control the current value of each lamp, so that the brightness of the lamp changes in the range of 0 ~ 100% according to the needs, and the power consumption of the lamp also changes, so the lighting system realizes the secondary energy saving.
In addition, Japan's logistics support department has also adopted the principle of "lighting on demand, energy conservation and emission reduction", and determined the lighting demand of each road section at different times according to different garage size, parking space location and number, and garage shape, so as to carry out professional design and make full use of modern information technology, Three sets of lighting schemes, namely "daily energy-saving mode", "holiday super energy-saving mode" and "emergency full light mode", have been formulated to form intelligent Internet of things solutions, so as to ensure in-depth realization of on-demand lighting and minimize direct energy consumption.
"Thank you very much for the products and services provided by Ming Feng Lighting. This garage renovation not only replaced energy-saving lamps, but also realized more refined energy management. Next, the energy saving office plans to apply the new intelligent lighting system to the public areas of classrooms and buildings, aiming to achieve the goal of intelligent facilities, convenient services and refined management through intelligent means. " The relevant person in charge of Japan's logistics support department said.
