Q:Are there any differences between fluorescent lamps and energy-saving lamps? What are the differences between them?: Material luminescence can be divided into two categories: one is the material heating, thermal radiation and the light, the other is the object of excited energy absorption and the transition to the excited state (non steady state) in reverse to the ground state in the process of releasing energy in the form of light. The luminescent materials with rare earth compounds as matrix and rare earth elements as activators are mostly in the latter category, namely rare earth phosphors. Rare earth elements are rich in electronic energy levels, because 4f orbitals exist in the electronic configurations of rare earth atoms, which create conditions for a variety of energy levels to achieve a wide range of luminescence properties.

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: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:Maintenance and repair of fluorescent lamp: Don't switch the lights too often. Too much lighting can cause premature darkening of both ends of the tube, which affects the power output of the tube, and it should be noted that the lights should be switched on for 5 to 15 minutes after the lights are turned off.

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.

Q:What's the difference between an energy-saving fluorescent lamp and a LED light?: When the two semiconductors are connected, a P-N junction is formed between them.When the current passes through the wire acting on the wafer, the electrons are pushed into the P region and combined with the electron hole in the P region,Then energy is emitted in the form of photons, that is, light.

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 speed of the fluorescent lamp is fast, the dimming precision is high, and the dimming parameters can be adjusted in real-time. Because the dimming circuit is mainly composed of electronic components, it is relatively small in size, light in quality and high in performance price ratio. But the fluorescent lamp ballast with power factor correction circuit, power factor dimming ballast is greater than 0.95 characters, this means that when people are in the process of dimming of the fluorescent lamp in the energy consumption is changed accordingly. This is essentially different from the dimming of controlled silicon.
