1. LED light source has high luminous efficiency
Luminous efficiency comparison: incandescent light efficiency is 10-15lm, tungsten halogen light efficiency is 12-24 lumens / watt, fluorescent lamp 50-90 lumens / watt, sodium lamp 90-140 lumens / watt, most of the power consumption becomes heat loss.
LED light effect: It can be sent to 50-200 lumens / watt, and the monochromatic light is good, the spectrum is narrow, no need to filter, and it can directly emit colored visible light.
2. Low power consumption of LED light source
LED single tube power 0.03-0.06 watts, using DC drive, single tube driving voltage 1.5-3.5 volts. The current of 15-18 mA reflects the speed quickly, and can be operated at high frequency. When the same lighting effect is used, the power consumption is one ten thousandth of an incandescent lamp and one half of a fluorescent tube. Japan estimates that if it is used LEDs with a light efficiency twice as high as fluorescent lamps can replace half of the incandescent and fluorescent lamps in Japan, which can save 6 billion liters of crude oil per year. A fluorescent lamp with the same effect has 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 tungsten halogen lamps use electronic light field to emit light, and the filament is easy to burn, thermal deposition, and light attenuation. The LED lamp is small, light, and epoxy resin encapsulated, which can withstand high-strength mechanical shocks and Vibration, not easy to break, the average life span is 3-50000 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 heat radiation, cold light source, safe to touch, can control light type and light angle, light color, no glare, no mercury, sodium and other substances that may endanger health.
5. LED light source is environmentally friendly
LEDs are all-solid luminous bodies, impact-resistant, unbreakable, recyclable waste, no pollution, reduce a large amount of harmful gases such as sulfur dioxide and nitrides, and generate greenhouse gases such as carbon dioxide to improve people's living environment. They can be called "green lighting sources."
There are currently three types of white light LED technology: one, using the principle of three primary colors and the three ultra-bright LEDs that can be produced, such as red, green, and blue, are mixed into white at a ratio of 3: 1: 6 light intensity, and two, using super Highly InGan blue LED, a little yttrium diamond pomegranate as the main phosphor is added to the tube. It can produce yellow-green light under the excitation of blue light, and this yellow-green light can be combined with the transmitted blue light to synthesize white light. The 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. Perhaps LEDs are more expensive than traditional light sources, but with one year of energy saving, the investment in light sources is recovered to obtain a net energy saving period of several times per year in 4-9 years.
