Q:Is the energy-saving lamp a fluorescent lamp?: The energy-saving lamp belongs to the fluorescent lamp class.The same power of energy-saving lamps should be incandescent lamp brightness of more than 3.5--8 times.

Q:Are there any differences between fluorescent lamps and energy-saving lamps? What are the differences between them?: When the lamp is energized, the tungsten electrode is discharged between the two ends of the lamp. Light emitting from short wave radiation into visible light mainly by phosphor. Rare earth three primary fluorescent lamps, which contain yttrium, europium and terbium rare earth phosphors, emit brighter light and are closer to the solar spectrum than standard fluorescent lamps. At the same time, the light can save 50% energy consumption, and the three primary color phosphor powder is mixed by three kinds of phosphor powder of three narrow band red emitting (611nm), green (545nm) and blue (450nm) color spectrum.

Q:Why can fluorescent lamps emit various colors?: Phosphor of red, green and blue three colors, yttrium oxide (red light, peak wavelength 611nm), magnesium aluminate (emitting green light),The peak wavelength is 541nm) and the barium magnesium aluminate (blue light, with a peak wavelength of 450nm) mixed in a certain proportion can be obtainedFluorescent powder of any color can be sent out

Q:How to adjust light in fluorescent lamp: The dimming of fluorescent lamp is a method of frequency modulation dimming. The power adjustment of the fluorescent light source is realized by the characteristics of the voltage conversion ratio and frequency correlation of the high frequency transformer in the ballast. The higher the frequency of the high frequency transformer in the ballast, the lower the output voltage of the high frequency transformer; the lower the frequency of the high frequency transformer, the higher the output voltage of the high-frequency transformer. The control circuit can adjust the oscillation frequency of the high frequency transformer, and can adjust the output luminous flux of the fluorescent lamp.

Q:Maintenance and repair of fluorescent lamp: Pay attention to maintaining a ventilation environment, not only to take away the dust, but also to reduce the temperature of the tube so as to extend the life of the tube. 1, the fluorescent lamp heating easy to attract dust, clean and ready to turn off the power, and then try to make the indoor air circulation, with a twist dry cloth stained with a little cleaner to clean the tube gently, and then use a clean dry cloth to clean the cleaning agent.

Q:What's the difference between an energy-saving fluorescent lamp and a LED light?: The semiconductor wafer consists of two parts,One part is the P type semiconductor, in which the hole dominates,The other end is the N type semiconductor, which is mainly electronic here.

Q:What are the types of fluorescent lamps?: The single side compact fluorescent lamp. The lamp, fluorescent lamp ballast and the lamp tightly integrated (ballast inside the base), in addition to destruction, to put the demolition, it was known as the "compact" fluorescent lamp. Because no additional ballast, the driving circuit in the ballast. The fluorescent lamp is self ballasted fluorescent lamp and fluorescent lamp. The lamp start by E27 lamp directly with the power supply network connection, can directly replace incandescent lamps.

Q:What is a fluorescent lamp? What are fluorescent lights?: The traditional fluorescent lamp type fluorescent lamp and electrodeless fluorescent lamp, traditional fluorescent lamp is a low pressure mercury lamp, mercury vapor is the use of low pressure in the discharge process of ultraviolet radiation, so that the phosphors emit visible light emitting principle, so it belongs to low pressure arc discharge light source. The traditional fluorescent lamp is equipped with two filaments. The filament is coated with electronic emission materials, three yuan carbonate (barium carbonate, strontium carbonate and calcium carbonate), commonly known as electronic powder. The alternating filament acts as a cathode and anode under alternating voltage. The inner wall of the lamp tube is coated with phosphor powder. The tubes are filled with argon at 400Pa-500Pa pressure and a small amount of mercury. After discharge, the liquid mercury evaporates into mercury vapor at a pressure of 0.8 Pa. In the electric field, the mercury atoms continuously from the original state is excited into the excited state, then spontaneous transitions to the ground state, and the radiation wavelength of 253.7nm and 185nm (the peak value of ultraviolet wavelength is 253.7nm, total radiation energy 70-80%; peak wavelength is 185nm, accounting for about 10% of the total radiant energy), to the release of excess energy. The fluorescent powder absorbs ultraviolet radiation and emits visible light. Fluorescent powder is different, the light is also different, that is, fluorescent lamps can be made white and various colors reasons.
