Calculate the electricity cost of 10 lamps for household use: (Comparative data basis: 15-20lm/w for ordinary incandescent lamps, 30-60lm/w for ordinary energy-saving lamps, 120-150lm/w for LED energy-saving lamps, this data is only for comparison For reference purposes, the pricing of local markets is slightly different.)
1, ordinary incandescent lamp electricity fee:
10 x 60W / only × 5 hours / day × 365 days / year = 1095000W / hour = 1095 degrees
One year electricity fee = 1095 degrees × 1 yuan / degree = 1095 yuan
2. General energy-saving lamp electricity fee:
10 x 15W / only × 5 hours / day × 365 days / year = 273735W / hour = 274 degrees
One year electricity fee = 274 degrees × 1 yuan / degree = 274 yuan
3, LED energy-saving lamp electricity fee:
10 x4w / only x5 hours / day x365 days / year = 73000w / hour = 73 degrees
One year electricity fee = 73 degrees × 1 yuan / degree = 73 yuan
One year to save electricity costs LED energy-saving lamps relative to ordinary incandescent lamps: 1095 yuan - 73 yuan = 1022 yuan
Initial purchase of lighting input cost calculation:
1, ordinary incandescent lamp: 10 × 1 yuan / only = 10 yuan, the average service life of 2000 hours (about 1 year).
2, LED energy-saving lamps: 10 × 55 yuan / only = 550 yuan, the average service life of 30,000 hours (about 6 years).
Comprehensive comparison of the above data can be recovered in one year: LED energy-saving lamps are invested 550 yuan - Puergy energy-saving lamps 10 yuan = 540 yuan -
Saving electricity costs 1022 yuan / year = 482 yuan (surplus)
Calculate the electricity cost of a medium-sized supermarket using 1000 lamps: (Comparative data: 15-20lm/w for ordinary incandescent lamps, 30-60lm/w for ordinary energy-saving lamps, 120-150lm/w for LED energy-saving lamps, this data For comparison purposes only, pricing in different markets varies slightly.)
1, ordinary incandescent lamp electricity fee:
1000 × 60W / only × 12 hours / day × 365 days / year = 262800000W / hour = 262800 degrees
One year electricity bill = 262,800 degrees × 1 yuan / degree = 262,800 yuan
2. General energy-saving lamp electricity fee:
1000 × 15W / only × 12 hours / day × 365 days / year = 65700000W / hour = 65700 degrees
One year electricity bill = 65700 degrees × 1 yuan / degree = 65700 yuan
3, LED energy-saving lamp electricity fee:
1000 x4w/only x12 hours/day x365 days/year=17520000w/hour=17520 degrees
One year electricity bill = 17520 degrees × 1 yuan / degree = 17520 yuan
One year to save electricity costs LED energy-saving lamps relative to ordinary energy-saving lamps: 65700 yuan - 17520 yuan = 48180 yuan
Initial purchase of lighting input cost calculation:
1. Ordinary energy-saving lamps: 1000 × 20 yuan / only = 20,000 yuan, with an average service life of 8,000 hours (about 2 years).
2, LED energy-saving lamps: 1000 × 55 yuan / only = 55,000 yuan, the average service life of 30,000 hours (about 6 years).
Comprehensive comparison of the above data can be recovered in one year: LED energy-saving lamps invested 55,000 yuan - Puergy energy-saving lamps 20000 yuan = 35,000 yuan - saving electricity costs 48180 yuan / year = 13180 yuan (surplus)
