Why are energy saving lanternThe ordinary incandescent lamp worksThe ordinary incandescent light efficiency about 10 lumens per watt or so, life expectancy of about 1,000 hours, it works: When the lamp access circuit, current flows through the filament, the current thermal effects, so that given a continuous visible light and incandescent infrared, this phenomenon can be aware of the filament temperature rose to 700K, as a result of a high temperature when the filament, most of the energy is wasted in the form of infrared radiation, because the filament temperature is high, evaporation is also fast, so life expectancy Great shortened about 1000 hours. The working principle of energy-saving lampsMainly through the energy-saving lamp ballast to the lamp filament heating temperature of about 1160K, the filament began to emit electrons (because the filament on a number of electronic powder coated), electron impact inelastic collisions of argon atoms, argon atoms after the collision Also hit was the energy of mercury atoms and mercury atoms absorb the energy generated after the transition ionization, issued 253.7nm UV, ultraviolet excited light-emitting phosphors, fluorescent lights at work due to the temperature of the filament of about 1160K, the temperature of the work than incandescent 2200K-2700K much lower, so it might also have increased life expectancy, reaching more than 5,000 hours, because it does not exist, as current incandescent heat effect, the energy conversion efficiency of phosphor is also high, reaching more than 50 lumens per watt. Generally speaking, in the same wattageIn addition to energy-saving lamps white (cold light) in addition, there is still yellow (warm light). Generally speaking, in the same wattage, under an energy-saving 80% energy than incandescent lamps, with an average life expectancy eight times the thermal radiation is only 20%. Non-strict case, a 5-watt energy-saving bright lights can be seen as equal to 25 watt incandescent lamp, 7-watt energy-saving bright lights equivalent to about 40 watts, 9 watts equivalent to about 60 watts.A compact fluorescent lamp:http://en.wikipedia.org/wiki/Compact_fluorescent_lampEnergy Saving Light Bulbs, Compact Fluorescent Lamp:http://www.energysaving-lightbulb.co...ucts/index.htmEnergy Saving Bulb Calculator ?C General:http://www.lightbulbs-direct.com/article/energy-saving/How energy saving lamp saves energy ?http://answers.yahoo.com/question/in...1074358AAzEwuX
