1. Budget saving.

1) Long life span

Energy-saving lamps generally have a life of 1800 hours, calculated in accordance with 10 hours of lighting per day for 180 days. LED lamps have a life of 70,000 hours, calculated in accordance with 10 hours of lighting per day for 7000 days (20 years). If you calculate an average of 14W energy-saving lamps 12 yuan in 20 years to change 40 bulbs (480 yuan). An LED lamp (Led Lamp) bulb 5W for an average of 70 yuan, total savings of 410 yuan.

2 ) Power saving

A 40W ordinary light bulb per hour power consumption 0.04 degrees * 0.8 yuan = 0.032 yuan

40W bulb = 5W LED consumes 0.005 degrees per hour * 0.8 = 0.004 yuan

Saving 0.028 yuan per hour * 10 hours / day * 365 days = 102.2 yuan (compared to the savings of one bulb a year)

★ Example.

1000 40W incandescent lamps and 1000 5W LED light source cost comparison: (average use 10 hours per day)

A 40W incandescent lamp: a year of electricity consumption: 0.04 * 10 * 365 = 146 degrees.

Electricity: 146 * 0.8 = 116.8 yuan / year

1000 40W incandescent lamps: electricity: 116.8 yuan * 1000 = 116,800 yuan / year

A 5W LED lamp: a year electricity consumption: 0.005 * 10 * 365 = 18.25 degrees

Electricity: 18.25 * 0.8 = 14.6 yuan / year

1000 5W LED lamps (Led Lamp): Electricity cost: 14.6*1000=14600 Yuan/year

Total electricity cost savings: 102,200 yuan/year

2、Other advantages.

1, does not produce light pollution and heat radiation 2, and colorful and realistic, graphic variation

3, maintenance-free 4, easy to control

5, environmental protection, no ultraviolet light harmless to humans

(1) energy-saving: about 80% less power consumption than incandescent lamps of the same brightness.

(2) long life: life of up to 50,000 hours, equivalent to 50 times the traditional incandescent lamp.

(3) environmental protection: no harmful metals mercury, the spectrum does not contain infrared and ultraviolet.

(4) dynamic control of brightness and color: continuously adjustable brightness, high color purity, dynamic color change and digital control can be achieved.

(5) flexible shape and size: can realize organic integration with the building.

(6) low working voltage: effectively ensure personal safety
