Comparison of luminous efficiency: incandescent lighting effect is 10-15lm, halogen tungsten lighting effect is 12-24 lumens/watt, fluorescent lamp is 50-90 lumens/watt, sodium lamp is 90-140 lumens/watt, most of the power consumption becomes heat loss.
LED light effect: It can emit 50-200 lumens/watt, and the monochromaticity of the light is good, the spectrum is narrow, and it can directly emit colored visible light without filtering.
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 is 15-18 mA, the reflection speed is fast, and it can be operated at high frequency. When used in the same lighting effect, the power consumption is one ten thousandth of the incandescent lamp and one half of the fluorescent tube. Japan estimates that if it is used LEDs, which are twice as effective as fluorescent lamps, can replace half of incandescent and fluorescent lamps in Japan, saving 6 billion liters of crude oil each year. A fluorescent lamp with the same effect is more than 40 watts, while the power of each LED is only 18 watts. .
3. Long service life of LED light source
Incandescent lamps, fluorescent lamps, and halogen tungsten lamps use electronic light field radiation to emit light, and the filaments are easy to burn, heat deposition, and light attenuation. Vibration, not easy to break, the average lifespan is 30,000-50,000 hours, and the service life of LED lamps can reach 3-5 years, which can greatly reduce the maintenance cost of lamps and avoid the pain of frequent lamp replacement.
