1.LED light source has high luminous efficiency
Comparison of luminous efficiency: incandescent light efficiency is 10-15lm, tungsten halogen light efficiency is 12-24 lumens/watt, fluorescent light 50-90 lumens/watt, sodium light 90-140 lumen/watt, most of the power consumption becomes heat loss.
LED light efficiency: It can emit 50-200 lumens/watt, and its light emission has good monochromaticity and narrow spectrum. It can directly emit colored visible light without filtering.
2.LED light source consumes less power
The LED single tube power is 0.03-0.06 watts, using DC drive, and the single tube driving voltage is 1.5-3.5 volts. Current 15-18 mA has a fast response speed and can be operated at high frequency. When used with the same lighting effect, the power consumption is one-ten thousandth of that of incandescent lamps and one-half that of fluorescent tubes. It is estimated in Japan that if it is used LEDs, which are twice as efficient as fluorescent lamps, can replace half of Japan’s incandescent and fluorescent lamps, saving the equivalent of 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.LED light source has long service life
Incandescent lamps, fluorescent lamps, and tungsten halogen lamps use electronic light field radiation to emit light. The filament emits light and is prone to burning, heat deposition, and light attenuation. LED lamps are small in size, light in weight, and encapsulated in epoxy resin, which can withstand high-strength mechanical impact and Vibration-resistant, not easily broken, with an average lifespan of 30,000-50,000 hours, the service life of LED lamps can reach 3-5 years, which can greatly reduce the maintenance costs of lamps and avoid the pain of frequent lamp replacement.
4. Strong safety and reliability
It has low calorific value, no thermal radiation, cold light source, safe to touch, can accurately control the light pattern and angle of light, and light color, no glare, and does not contain mercury, sodium and other substances that may be harmful to health.
5.LED light source is beneficial to environmental protection
LED is an all-solid-state light emitter, is impact-resistant and not easily broken, is recyclable, has no pollution, reduces the generation of harmful gases such as sulfur dioxide and nitrides, and greenhouse gases such as carbon dioxide, and improves people’s living environment. It can be called a “green lighting source.”
There are currently three technologies for producing white LEDs: one, which uses the principle of three primary colors and the three ultra-high brightness LEDs of red, green, and blue that can be produced to mix the light intensity in a ratio of 3:1:6 to produce white; the other, which uses ultra-high-brightness LEDs Highly InGan blue LED, with a small amount of yttrium-diamond-granite-based phosphor added to the tube, it can produce yellow-green light under blue light excitation, and this yellow-green light can be combined with the transmitted blue light to synthesize white light. The three types are incompatible with ultraviolet light. Light LED uses ultraviolet light to excite three primary color phosphors or other phosphors to produce white light mixed with multiple colors.
6.LED light source is more energy-saving
Of course, energy saving is the main reason why we consider using LEDs. LEDs may be more expensive than traditional light sources, but using energy savings in one year to recoup the investment in light sources will lead to a net payback period of several times the annual energy savings in 4 to 9 years.
