Shape due to the different energy-saving lamp tubes, into U-tube, spiral and straight tube of three.
Energy-saving light rare earth trichromatic official name is the compact fluorescent lamps, 20th century, was born 70 years Philips in the Netherlands. This light source to achieve the same light output in the premise, just an ordinary incandescent electricity cost 1 / 5 to 1 / 4, which can save a lot of lighting, power and cost, it is called energy-saving lamps. Today we talk about energy-saving products are mainly for the incandescent terms. Ordinary incandescent light efficiency of about 10 lumens per watt or so, life is about 1000 hours, it works: When the lamp access circuit, current flows through the filament, heating effect of current, so that given a continuous visible light and incandescent Infrared, this phenomenon can be aware of the filament temperature is raised to 700K, due to the work of the filament temperature is high, most of the energy is wasted in the form of infrared radiation, and the filament temperature is high, evaporation is also fast, so life expectancy Great reduced, about 1000 hours.
Type: Bayonet, Threaded; high and low frequency; white and yellow light, etc.
