FAQ
- 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.
- Are there any differences between fluorescent lamps and energy-saving lamps? What are the differences between them?
- 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.
- Why can fluorescent lamps emit various colors?
- Have you ever seen fluorescence? After the surface of the object is coated with fluorescent material, the light can be sent out at night to absorb various colors of light,Silver light powder material is different, the light is also different
- How to adjust light in fluorescent lamp
- Tolerable。 Dimming is mainly the frequency modulation, generally from 10-100%, but must take into account the small power when the filament emitting insufficient electronic problems. Electronic dimming ballast for fluorescent lamp is a molded product. ORSAM has.LUTRON fluorescent lamp, dimming module and dimming ballast are easy to use.
- 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.
- What's the difference between an energy-saving fluorescent lamp and a LED light?
- Different lighting principleAn energy-saving fluorescent lamp uses mercury vapor at low pressure to release ultraviolet light after energizing so as to make fluorescent powder coated on the inner wall of the lamp tube shine.The light emitting element of the LED is a semiconductor crystal,
- What are the types of fluorescent lamps?
- Straight tube type fluorescent lamp according to the diameter is divided into: T12, T10, T8, T6, T5, T4, T3 and other specifications. The specification "T+" combination, said digital diameter mm value. Its meaning: a T=1/8 inch, one inch is 25.4mm; the number of digital T. Such as T12=25.4mm*1/8*12=38mm.
- 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.
