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.s
Maintenance and repair of fluorescent lamp
- If the voltage is low, the lamp will light up in the beginning of the two pollutants emitted tungsten, so that the lamp tube produces many point, one of the reasons to become tube damage so that, as far as possible in the high voltage under the condition of light.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?
- 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 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
- 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 fluorescent tube is a glass tube, the inner wall is coated with a layer of fluorescent powder (magnesium tungstate, calcium tungstate, zinc silicate, etc.), different phosphors can emit light of different colors. The lamp tube is filled with thin inert gas (such as argon gas) and mercury vapor, and both ends of the lamp tube have a filament made of tungsten, and the filament is coated with an oxide which is easy to emit electrons after being heated. When the filament passes through the current, the filament in the lamp tube emits electrons, and the temperature in the tube is increased, and the mercury is evaporated. Along with the gradual rise in temperature in the tube, mercury vapor free, inert gas molecular collision when mercury vapor discharge, arc discharge, it radiates invisible ultraviolet light, visible light fluorescent powder in the inner wall of the tube after UV excitation.s
