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.s
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.s
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.s
Why can fluorescent lamps emit various colors?
- The fluorescent lamp uses this principle. The fluorescent lamp itself sends out ultraviolet light, and the fluorescent powder coated on the tube wall absorbs ultraviolet lightAfter the line is changed into visible light, the phosphor is different and the color of the light is also differents
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.s
How to adjust light in fluorescent lamp
- Fluorescent light dimming can also extend the life of the light source, dimming to 90%, doubling the life of the light source; dimming to 80%; the light source life is extended two times; dimming to 50%; the light source life is extended ten times. Although this is a theoretical value, but shows that fluorescent lamp dimming can also reduce the frequency of replacement of the light source, the light source in the unit of time to reduce the amount of change a lot, it also has its positive significance for energy saving and emission reduction.s
What are the types of fluorescent lamps?
- Color fluorescent lamp. Common nominal power of 20W, 30W, 40W., T5, T4 in diameter, luminous flux G5, G13. color fluorescent lamp with T8. lamp is low, suitable for shop windows, advertisements or similar places decoration and color display. (3) the annular fluorescent lamp. In addition to shape, no more the big difference between the annular fluorescent lamp and tube fluorescent lamp. Common nominal power of 22W, 32W, 40W., G10q.. Lamp mainly for ceiling lamps, chandeliers and other supporting source, for family, shopping malls and other lighting.s
What is a fluorescent lamp? What are fluorescent lights?
- Because most of the energy consumed by fluorescent lamps is used to produce ultraviolet light, fluorescent lamps are much better than incandescent and halogen tungsten lamps, so they are energy saving electric light sources at present. The fluorescent lamp is about 0.8Pa pressure mercury vapor discharge, under the action of electric field in the discharge process, the valence electrons of mercury atoms continuously from the original state is excited into an excited state, and excited state of spontaneous returns to the ground state, the valence electron is converted to electromagnetic radiation, and radiation at the beginning 3.7nm UV (ultraviolet also about 10% 85nm). The phosphor on the inner wall of the butcher's carrier tube absorbs ultraviolet light from the 353.7nm and transforms it into visible light. Electrodeless fluorescent lamp is electrodeless lamp, it cancels the filament and the electrode of the traditional fluorescent lamp, using the principle of electromagnetic coupling, the mercury atoms from the original state into the excited state, the luminescence principle and system of fluorescent lamp is similar, is now the new energy-saving light source. The utility model has the advantages of long service life, high luminous efficiency, good color rendering, etc..s
