molybdenum disk tungsten pros and cons

CFLs ordinary tungsten tungsten poles pass, after heating can emit electrons in both sides of the lamp with a relatively high voltage to form an electric field, the electrons

Lamp will be accelerated, the formation of a certain tungsten tube flow rate and energy electrons, is drawn into the vacuum tube, which is filled with mercury, mercury is the electron current in the electric Child playing with a certain speed on mercury atoms that are excited mercury atoms become excited state ions, known as happened step, the excited state of mercury over a very short Time to spontaneously fall back to its original state. While the release of ultraviolet light, ultraviolet light can not be used for lighting. Common energy-saving lamps have an ordinary lamp Tubes and getting mainstream trichromatic lamp, and has advantages compared to incandescent bulbs saving. The difference is that ordinary lamp color is low, but the lamp of the three primary colors The color showing natural sunlight, molybdenum disk and the color and light efficiency is more than an ordinary lamp. Energy-saving light sources contain mercury. Since the boiling point of mercury is Low to evaporate at room temperature, after crushing discarded fluorescent tubes, and immediately distributed to the surrounding mercury vapor, allows instantaneous ambient air concentration of mercury per cubic M 10 to 20 mg, the state's maximum allowable mercury concentration in the air of 0.01 milligrams per cubic meter. Mercury into the human body is difficult to be excluded. 1, the production During and after use of waste mercury contamination, mercury pollution is currently Western countries is considerable attention. 2, because it is glass, easily broken, bad transportation. Not Installed. 3, the power consumption is still too big.

4, easy to damage, short life, energy and money molybdenum plating this sentence is that it is not the best portrayal.‍
