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
- Fluorescent lamps have many circuits and require auxiliary devices, so they must be used in conjunction with the corresponding transformers and capacitors to ensure that the lamp is activated to the proper power.s
Is the energy-saving lamp a fluorescent lamp?
- The three primary colors of energy-saving lamps, high efficiency energy-saving fluorescent lamp, also known as compact fluorescent lamps and integrated fluorescent lamp, refers to the fluorescent lamp and ballast (ballast) are combined into a whole lighting equipment, the effective life of eight thousand hours or more.s
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 outs
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,s
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.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?
- 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.s
