1.High luminous efficiency
After decades of technological improvements, LEDs have greatly improved their luminous efficiency. The incandescent and tungsten halogen light effects are 12-24 lumens/watt, fluorescent lamps 50 to 70 lumens/watt, and sodium lamps 90 to 140 lumens/watt. Most of the power consumption becomes heat loss. The improved LED light efficiency will reach 50-200 lumens/watt, and its light has good monochromaticity and narrow spectrum. It can directly emit colored visible light without filtering.
2.Low power consumption
LED single tube power 0.03 ~ 0.06 watts, using DC drives, single tube driving voltage 1.5 ~ 3.5 volts, current 15 ~ 18 mA, fast response speed, can operate on high frequency. Under the same lighting effect, the power consumption is one of ten-thousandth that of incandescent light bulbs and one half that of fluorescent tubes. Japan estimates that if LEDs with twice the light efficiency than fluorescent lamps are used to replace half of the incandescent lamps in Japan Fluorescent light. It can save 6 billion liters of crude oil annually. In the case of bridge guardrail lights, a fluorescent lamp with the same effect is more than 40 watts, while the power of each LED is only 8 watts, and it can be colorfully changed.
3.Long service life
Under normal circumstances, when using LEDs, the light attenuation can be reduced to 70%. The nominal life is 100,000 hours, which reduces the replacement frequency and other maintenance work. LED lamps have a service life of 5 to 10 years, which can greatly to reduce the maintenance costs of the lamps and avoid the pain of frequent lamp changes.
