1.LED light source high luminous efficiency
Comparison of luminous efficiency: incandescent light efficiency of 10-15lm, halogen light efficiency of 12-24 lumens / watt, fluorescent 50-90 lumens / watt, sodium 90-140 lm / watt, most of the power into heat loss.
LED luminous efficiency: can be issued to 50-200 lm / W, and luminous monochromatic, narrow spectrum, no filtering, can be issued directly to the colored visible light.
2.LED light source power consumption less
Single LED power 0.03-0.06 watts, using DC drive, single-tube drive voltage 1.5-3.5 volts. Current 15-18 mA reflects fast, high-frequency operation, with the same lighting effects, power consumption is one ten thousandth of an incandescent lamp, fluorescent tube half, Japan estimates, as used Two times more efficient LED than fluorescent lamps Replace half of Japan's incandescent and fluorescent lamps, saving equivalent to 60 billion liters of crude oil each year, the same effect of a fluorescent lamp 40-watt, and the use of LED power of only 18 watts .
3.LED light source long life
Incandescent, fluorescent, tungsten halogen lamp is the use of electronic light field radiation, filament light easy to burn, heat deposition, light attenuation and other characteristics, and using LED lights small size, light weight, epoxy encapsulation, can withstand high mechanical shock and Vibration, not broken, the average life expectancy of 3-5 million hours, LED lamps life of up to 3-5 years, you can greatly reduce the maintenance costs of lamps and lanterns to avoid the frequent replacement of the pain.
