Energy-saving Characteristics Of LED Lamps
1. LED light source High luminous efficiency
Luminous efficiency comparison: incandescent light effect in 10-15lm, halogen tungsten light efficiency of 12-24 lumens/watts, fluorescent lamps 50-90 lumens/watts, sodium 90-140 lumens/watts, most of the power consumption into heat loss.
LED light effect: can be sent to 50-200 lumens/watts, and the luminous monochrome is good, narrow spectrum, no need to filter, can be directly emitted by colored visible light.
2. LED light source less power consumption
LED single tube power 0.03-0.06 watts, using DC drive, single tube drive voltage 1.5-3.5 volts. Current 15-18 Ma reflects fast, can be used in high-frequency operation, with the same lighting effect, the power consumption is the incandescent lamp one out of 10,000, fluorescent tube one-second, Japan estimates, such as the use of light efficiency than fluorescent lamps are twice times higher than the LED replacement of Japan's half incandescent and fluorescent lamps, annual savings equivalent to 6 billion liters of crude oil, The same effect of a fluorescent lamp more than 40 watts, and the use of LEDs per branch of power only 18 watts.
3. LED light source service life is long
Incandescent bulbs, fluorescent lamps, halogen tungsten lamps are radiated by electronic light fields, filament light is easy to burn, hot deposition, light attenuation and other characteristics, and the use of LED light volume small, light weight, epoxy resin packaging, can withstand high strength mechanical impact and vibration, not easy to break, the average life expectancy of 350,000 hours, LED lamp service life of up to 3-5 years, Can greatly reduce the maintenance cost of lamps and lanterns to avoid frequent change of the pain.
4. Strong security and reliability
Low calorific value, no thermal radiation, Lengguang, can be safely touched, can accurately control the light and luminous angle, light color and, no glare, no mercury, sodium elements and other substances that may endanger health.
5. LED light source is favorable to environmental protection
LED for all solid-state light-emitting, impact-resistant and not easily broken, waste can be recycled, no pollution to reduce the amount of sulfur dioxide and nitrogen and other harmful gases such as carbon dioxide and other greenhouse gases to improve living environment, can be called "green light source." ”
The production of white LED technology currently has three kinds of: one, using three-color principle and has been able to produce red, green, blue three ultra-high brightness LED light intensity 3:1:6 ratio mixed into white, two kinds, the use of ultra-high-altitude InGaN blue led, the total tube plus a little bit of yttrium diamond as the main body of the fluorescent powder, It can be stimulated under the blue light, and this yellow and green light can be combined with the glow of the Blu-ray synthesis of white light, three kinds of UV LED is not made, using ultraviolet light to stimulate the three phosphor or other fluorescent powder, resulting in multi-color mixed white light.
6. LED light source more energy-saving
Of course, energy-saving is the main reason we consider the use of LED, perhaps the LED is more expensive than the traditional light source, but with a year of energy-saving to recover the investment of light source, so as to obtain 4-9 years each year of energy-saving net cover period.
