Said LED energy saving, are relatively traditional incandescent. Because the LED is the principle of diode light, the energy conversion into light energy is much higher than the incandescent lamp. Specifically, the former is about 65%, the latter may be as low as only 5%! The rest are used to heat up. This is why the reasons why energy-saving led lights, and then led lights and ordinary incandescent lamp What is the difference
May be a lot of people know that there are several lights, but also know the effect of energy-saving lamps are energy-saving lamps, energy-saving lamps, incandescent. But the principle of one must not everyone understand.
Ordinary incandescent light effect about 10 lumens per watt, life expectancy of about 1000 hours or so, it works is: When the light access circuit, the current flow through the filament, the thermal effect of the current, so that incandescent light issued a continuous visible light and Infrared, this phenomenon in the filament temperature rose to 700K can be aware of the work of the filament temperature is very high, most of the energy in the form of infrared radiation wasted, because the filament temperature is high, evaporation is also fast, so life also Large and short, about 1000 hours or so; on the perspective of energy saving, the traditional incandescent lamp due to a large number of infrared energy loss and high temperature fever, short life, advanced energy-saving environmental protection lamp is an inevitable energy-saving revolution The
Energy saving lamp
In contrast, energy-saving environmental protection lights are mainly through the ballast to the lamp filament heating, about 1160K temperature, the filament began to launch electrons (because the filament coated with some electronic powder), the electronic collision of argon atoms produce inelastic Collision, argon atoms collide with the energy and then hit the mercury atoms, mercury atoms in the absorption of energy after the transition to produce ionization, issued 253.7nm UV, UV excitation phosphor light, because the fluorescent lamp operating temperature of about 1160K, than incandescent The work of the temperature 2200K-2700K much lower, so its life is also greatly improved, and the degree of energy saving, life expectancy of up to 5000 hours or more, because it does not exist incandescent as the current thermal effect, phosphor energy conversion efficiency is also very High, reaching 50 lumens per watt above.
LED (Light-Emitting-Diode Chinese meaning for the light-emitting diode) is a kind of energy can be converted into visible light semiconductor, it changed the incandescent tungsten light and energy-saving lamps three primary colors of light principle, and the use of electric field light. As led by the use of solid-state semiconductor chip as a luminescent material, and we used in the daily life of the bulb is made of metal luminescent materials, so the energy issued by the different, according to statistics, a red LED light to a certain brightness The energy required is 15 watts, while the traditional light bulb to achieve the same measure will consume up to 150 watts of energy; the other according to scientists, LED power when the light, 10% of the energy can be converted into light energy, and Incandescent bulb conversion efficiency is only 7-8%, it can be seen, to achieve the same lighting effects, LED lights than incandescent energy is obvious.http://www.new-lights.com
