FAQ

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?
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
The dimming of fluorescent lamp is a method of frequency modulation dimming. The power adjustment of the fluorescent light source is realized by the characteristics of the voltage conversion ratio and frequency correlation of the high frequency transformer in the ballast. The higher the frequency of the high frequency transformer in the ballast, the lower the output voltage of the high frequency transformer; the lower the frequency of the high frequency transformer, the higher the output voltage of the high-frequency transformer. The control circuit can adjust the oscillation frequency of the high frequency transformer, and can adjust the output luminous flux of the fluorescent lamp.s
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.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
