Installation method of LED lamp
The installation of LED energy-saving lamp is very simple. When installing, take down the original fluorescent lamp, replace it with LED energy-saving lamp, and remove the original ballast and starter, so that 220V AC power can be directly added to both ends of LED fluorescent lamp.
Energy saving effect analysis:
Before the renovation: 2000 ordinary fluorescent lamps were installed in an office building. The power of each fluorescent lamp is 45W / h, the lighting time is 8 hours per day, and the daily power consumption is 720 kWh (45W * 8 * 2000). According to the electricity charge of 1 yuan per kWh, the daily power consumption is 720 yuan, which is 21600 yuan for 30 days per month, and the annual power consumption is 259200 yuan, which is in urgent need Carry out energy-saving transformation.
After the transformation: we replace the original 45W fluorescent tubes with 9W LED energy-saving tubes. The same 2000 LED energy-saving tubes work 8 hours a day. From the perspective of energy-saving effect, the daily power consumption is 144kw, which is only 20% of that before the transformation. The electricity charge is only 144 yuan / day, 4320 yuan for 30 days a month, and the annual power consumption is only 51840 yuan.
