LED energy-saving lamps more energy than incandescent reasons

May 16, 2017

Lights, in our lives is everywhere, especially when home improvement, home bedroom, living room, restaurant, what should buy what kind of light? This problem has stumped a lot of people, but in fact, the lights have a lot of pay attention to the purchase. Today, the author to sort out the lights under the purchase of knowledge, interested friends can not miss. 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

Q: Q: LED energy-saving lamps more energy than incandescent compared to energy-saving environmental protection lights mainly through the ballast to the lamp filament heating, about 1160K temperature, the filament began to launch electrons (because the filament coated Some of the electronic powder), the electron 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 ionization, resulting in 253.7nm UV, UV excitation phosphor light, due to fluorescent Work when the temperature of the filament in 1160K or so, than the incandescent lamp work temperature 2200K-2700K much lower, so its life is also greatly improved, and the degree of energy saving, life of up to 5000 hours or more, because it does not exist incandescent Of the current thermal effect, the phosphor energy conversion efficiency is also 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 When 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 to light, there are 10 of the energy can be converted into light energy, and incandescent Light bulb conversion efficiency is only 7-8, we can see, to achieve the same lighting effects, LED lights than incandescent energy is obvious. According to the analysis, LED features are very obvious, long life, high luminous efficiency, no radiation and low power consumption. LED spectrum almost all concentrated in the visible frequency band, the luminous efficiency of more than 150lm / W (2010). The results show that the luminous efficiency of ordinary incandescent lamp is 12lm / W, the life is less than 2000 hours, the luminous efficiency of spiral energy-saving lamp is 60lm / W, the life is less than that of ordinary incandescent lamp, spiral energy saving lamp and T5 trichromatic fluorescent lamp. 8000 hours, T5 fluorescent lamp was 96lm / W, life of about 10,000 hours, while the diameter of 5 mm white LED light effect can be more than 150lm / W, life can be greater than 100000 hours. It is also predicted that the future of LED life limit will be infinite, it will dominate the market.
