1. LED luminous efficiency is high
Comparison of luminous efficiency: incandescent lamp, halogen tungsten light effect is 12-24 lumens / watt, fluorescent lamp 50-70 lumens / watt sodium lamp 90-140 lumens / watt, LED can reach 50-200 lumens / watt. In addition, the monochromaticity of the LED illumination is good, the spectrum is narrow, and no filtering is required, and the visible light can be directly emitted. The power consumption of most other lighting products becomes heat loss.
2. LED light source consumes less power
LED single tube power 0.03-0.06 watts, using DC drive, single tube drive voltage 1.5-3.5 volts. The current of 15-18 mA reflects the speed and can be operated at high frequency. In the case of the same lighting effect, the power consumption is one ten thousandth of the incandescent lamp, one-half of the fluorescent tube, Japan estimates, if adopted LEDs that are twice as efficient as fluorescent lamps replace half of Japan's incandescent and fluorescent lamps, saving up to 6 billion liters of crude oil per year. The same effect of a fluorescent lamp is more than 40 watts, while the power of each LED is only 8 watts. .
3. LED light source has a long service life
Incandescent lamps, fluorescent lamps, and tungsten halogen lamps are characterized by electron beam radiation, filament luminescence, thermal deposition, and light attenuation. LED lamps are small in size, light in weight, and encapsulated in epoxy resin to withstand high mechanical shocks. Vibration, not easy to break, the average life expectancy is up to 100,000 hours, and the service life of LED lamps can reach 5-10 years, which can greatly reduce the maintenance cost of lamps and avoid the pain of frequent lamp replacement.
4. LED light source is safe and reliable
Low calorific value, no heat radiation, cold light source, can be safely touched, can accurately control light type and illuminating angle, light color and no glare, no mercury, sodium and other substances that may be harmful to health.
