Zhengzhou DB- fluorescent structure

Zhengzhou DB- fluorescent interior structure of a conventional fluorescent lamp has two filaments, the filaments are coated with an electron-emitting material ternary carbonate (barium, strontium and calcium carbonate), commonly known as electronic powder. In the AC voltage is applied, the filament as a cathode and an anode to replace, the inner wall of the tube is coated with phosphor, filled with an argon gas pressure of 400Pa-500Pa and a small amount of mercury within the tube. Power, the liquid mercury evaporated to 0.8 Pa pressure mercury vapor, in the electric field, continue to be excited mercury atoms into an excited state from the original case, then spontaneous transition to the ground state, and radiation with a wavelength of 253.7nm and 185nm UV (main peak wavelength is 253.7nm, accounting for 70-80% of all radiant energy; the second peak wavelength is 185nm, accounting for about 10% of the radiant energy) to release the remaining energy. After absorption of ultraviolet radiation phosphor declared visible. Phosphor is not the same, the light is not the same as declaring that this is the fluorescent lamp can be made into a variety of colorful white and reason. Since most fluorescent lamp power consumption for the attack ultraviolet light, therefore, fluorescent light-emitting power than incandescent and tungsten-halogen high, attributed to energy-saving electric light.
