Energy-saving Characteristics Of LED Lamps

1. LED light source has high luminous efficiency
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 Japan's incandescent and fluorescent lamps, which can save 6 billion liters of crude oil every 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.
4. Strong safety and reliability
Low calorific value, no thermal radiation, cold light source, safe to touch, precise control of light type, light angle, light color, no glare, no mercury, sodium and other substances that may endanger health.
5. LED light source is beneficial to environmental protection
LED is an all-solid illuminant, impact-resistant and not easy to break, waste can be recycled, no pollution, reducing a large amount of harmful gases such as sulfur dioxide and nitrides, and greenhouse gases such as carbon dioxide, and improving people's living and living environment. It can be called "green lighting source."
There are currently three types of white LED production technologies: one, using the principle of three primary colors and three kinds of ultra-high-brightness LEDs that can be produced, red, green, and blue are mixed according to the ratio of light intensity 3:1:6 to form white; High InGan blue LED, the tube is always added with a little yttrium diamond pomegranate as the main phosphor, it can produce yellow-green light under the excitation of blue light, and this yellow-green light can synthesize white light with the blue light that passes through. Light LED, using ultraviolet light to excite three primary color phosphors or other phosphors, produces white light mixed with multiple colors.
6. LED light source is more energy-saving
Of course, energy saving is the most important reason for us to consider using LEDs. Maybe LEDs are more expensive than traditional light sources, but the investment in light sources can be recovered after one year of energy saving, so as to obtain several times the annual net income of energy saving in 4-9 years.
