1, LED light source has high luminous efficiency
Comparison of luminous efficiency: incandescent lamp and halogen tungsten lamp effect is 12-24 lumen / tile, fluorescent lamp 50-70 lumen / sodium lamp 90-140 lumen / tile, and most of the power consumption becomes heat loss.
LED light effect: can be sent to 50-200 lumens / watts, and the luminescent monochromatic good, narrow spectrum, without filtration, can directly produce colored visible light.
2, LED light source is less power consumption
LED single tube power 0.03-0.06 watts, DC drive, single drive voltage 1.5-3.5 volt. The current 15-18 Ma fast response speed, in high frequency operation, under the same lighting effect, power consumption is 1/10000 of incandescent lamp, fluorescent tube 1/2, Japan''s estimated, incandescent and fluorescent lamps, such as the use of light efficiency than fluorescent lamp 2 times higher LED to replace Japan half a year can save considerable in 6 billion liters of crude oil, a fluorescent lamp of the same effect more than 40 watts, and the use of LED power each only 8 watts.
3. Long service life of LED light source
Incandescent lamp, fluorescent lamp, halogen lamp by using electronic light radiation emitting filament burnability, thermal deposition, light attenuation, and the LED lamp has the advantages of small size, light weight, epoxy resin packaging, can withstand high mechanical shock and vibration, not easily broken, the average life expectancy of 100 thousand hours, LED lamp the service life of up to 5-10 years, can greatly lower the maintenance cost of the lamp arc lamp change often to avoid suffering.
4, LED light source is safe and reliable
Low calorific value, no thermal radiation, cold light source and safe touch can precisely control light and lighting angle, light and color, no glare, mercury and sodium elements and other substances that may be hazardous to health.
5, LED light source is favorable for environmental protection
LED can improve the living environment of people by improving the living environment of all living things, such as solid solid luminescent body, impact resistance, no breakage, recyclable waste, no pollution, reduction of harmful gases such as sulfur dioxide and nitrides and carbon dioxide and so on. It can be called "green lighting source".
The production of high brightness LED light intensity of 1:2:0.38 mixed according to the proportion of white, two, uses the super InGan blue LED, the fluorescent powder, add a little pipe on the yttrium drill as the main body of the pomegranate which can produce yellow green, and yellow green light and white light into this with hints of Lan Guanghe under blue light, three is not LED by UV, UV induced three color phosphor or other fluorescent powder, generate a mixture of white light.
6, of course, energy saving is the main reason for us to consider the use of LED light source. Maybe LED light source is more expensive than traditional light source, but with a year of energy saving, we can recover the investment of light source, so that we can get several times of energy saving net coverage period in 4-9 years.
