LED Light Save Energy
LED light source high luminous efficiency
Luminous efficiency comparison: incandescent light effect in 10-15lm, halogen light effect of 12-24 lumens / watt, fluorescent lamp 50-90 lumens / watt, sodium lamp 90-140 lumens / watt, most of the power consumption into heat loss.
LED light effect: can be sent to 50-200 lumens / watt, and the luminous monochromatic good, narrow spectrum, without filtering, can be issued directly colored visible light.
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 mAh to reflect the speed, can be used in high-frequency operation, with the same lighting effects in the case, the power consumption is one thousandth of incandescent, fluorescent tube half, Japan estimates, such as the use of The luminous efficiency of fluorescent lamps than the LED 2 times more than half of Japan to replace incandescent and fluorescent lamps, the annual savings of the equivalent of 6 billion liters of crude oil, the same effect of a fluorescent lamp 40 watts, while the use of LED power of only 18 watts.
LED light source long life
Incandescent lamp, fluorescent lamp, halogen lamp is the use of electronic light field radiation, light filament easy to burn, heat deposition, light attenuation and other characteristics, and the use of LED lamp small size, light weight, epoxy resin package, can withstand high-strength mechanical shock and Vibration, easy to break, the average life of 3-5 million hours, LED lamp life of up to 3 - 5 years, can greatly reduce the maintenance costs of lamps to avoid frequent changes in the lamp.
Strong security and reliability
Low heat, no heat radiation, cold light source, can be safe to touch, can accurately control the light and light angle, light color and, no glare, mercury, sodium and other substances may harm health.
LED light source is environmentally friendly
LED is a solid solid body, the impact is not broken, waste can be recycled, no pollution to reduce a large number of sulfur dioxide and nitrides and other harmful gases and carbon dioxide and other greenhouse gases to improve people living environment, can be called "green lighting.
Production of white LED technology There are three: one, the use of three primary colors and has been able to produce red, green and blue three ultra-high brightness LED by light intensity 3: 1: 6 ratio made of white, two, Height InGan blue LED, the tube on the total plus a little yttrium diamond pomegranate as the main body of the phosphor, it can produce blue-green light in the blue light, and this yellow and green light can be made with blue light through the light, three are not UV Light LED, the use of UV light trichromatic phosphor or other phosphor, resulting in multi-color mixture of white light.
LED light more energy efficient
Of course, energy saving is the most important reason we consider the use of LED, LED may be more expensive than the traditional light, but with a year of energy-saving light source to recover the investment, resulting in 4-9 years several times a year of energy-saving net cover period.
Constant current source drive is the best way to LED drive, the use of constant current source drive, not in the output circuit series current limiting resistor, LED current flowing through the external power supply voltage changes, ambient temperature changes, and LED parameter dispersion Influence, which can adhere to the current constant, full of LED to play a variety of excellent features.
The use of LED constant current power supply to the LED lighting, as the power supply during the work will automatically detect and control the current flowing through the LED, so do not worry about the power of the instantaneous high current flows through the LED, do not worry about the load short-circuit burn Bad power supply.
