1.The LED light source has high luminous efficiency.
luminescent efficiency comparison: incandescent lamp light effect in 10-15LM, halogen tungsten light effect of 12-24 lumens/tile, fluorescent lamp 50-90 lumens/tile, sodium lamp 90-140 lumens/watt, most of the power consumption into heat loss.
LED light effect: can be sent to 50-200 lumens/watts, and luminous monochrome good, narrow spectrum, no need to filter, can directly emit colored visible light.
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. Current 15-18 Ma reflects fast, can be used in high-frequency operation, in the same lighting effect, power consumption is one out of 10,000 of incandescent lamps, fluorescent tube one-second, Japan estimates, such as the use of light efficiency than fluorescent lamps more twice times higher LEDs to replace half of Japan's incandescent and fluorescent lamps, each year can save the equivalent of 6 billion litres of crude oil,
The same effect of a fluorescent lamp more than 40 watts, and the use of LEDs per unit of power only 18 watts.
3.LED Light source has a long service life. Incandescent lamps, fluorescent lamps, halogen tungsten lamps are the use of electronic light field radiation luminescence, filament luminescence easy to burn, heat deposition, light attenuation and other characteristics, and the use of LED lamps small size, light weight, epoxy resin package, can withstand high-strength mechanical impact and vibration, not easy to break, life expectancy of up to 350,000 hours, LED lamps service life of UP
Can greatly reduce the maintenance cost of lamps to avoid the pain of often changing lights.
4. Strong safety and reliability.Low calorific, no thermal radiation, Lengguang, can be safely offset, can accurately control the light type 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 emitters, impact resistance is not easy to break, waste recyclable, no pollution to reduce a large number of sulfur dioxide and nitride and other harmful gases, as well as carbon dioxide and other greenhouse gas production to improve people's living environment, can be called "Green lighting light source."
” The production of white LED technology currently has three kinds: one, the use of three basic color principle and has been able to produce red, green, blue three ultra-high brightness led in accordance with the light intensity 3:1:6 proportion mixed into white, two species, the use of ultra-high InGaN blue led, its tube total plus a little yttrium drill pomegranate as the main body of fluorescent powder, It can produce yellow and green light excited by Blu-ray, and this yellow and green light can be combined with the revealed blue light, three kinds of non-production UV LED, the use of ultraviolet light excitation three basic color phosphor or other fluorescent powder, the production of multi-color mixed white light.
