FAQ

Are there any differences between fluorescent lamps and energy-saving lamps? What are the differences between them?

Rare earth phosphors are mainly used in office, store and factory high performance fluorescent lamps. Since the middle of 80s, with the development of less expensive fluorescent phosphor containing terbium, the application of this energy-saving lamp has been increasing rapidly. In mid 90s, the international launch of the TMT2 straight tube fluorescent lamp, the diameter of only 7mm, power is 6W~13W, light efficiency is 621m/W.T5 straight tube type fluorescent tube diameter is 16mm, power 14W~35W, 28W fluorescent light up to 104m/W, life is more than 16000h. in new development of high power light type 55W~120W is suitable for outdoor lighting compact energy saving rare earth fluorescent lamp, light efficiency more than 801m/W.

What are the types of fluorescent lamps?

The single side compact fluorescent lamp. The lamp, fluorescent lamp ballast and the lamp tightly integrated (ballast inside the base), in addition to destruction, to put the demolition, it was known as the "compact" fluorescent lamp. Because no additional ballast, the driving circuit in the ballast. The fluorescent lamp is self ballasted fluorescent lamp and fluorescent lamp. The lamp start by E27 lamp directly with the power supply network connection, can directly replace incandescent lamps.

Is the energy-saving lamp a fluorescent lamp?

Yes, the energy saving lamp is called compact fluorescent lamp. I hope it will be a happy holiday!

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.

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.

What's the difference between an energy-saving fluorescent lamp and a LED light?

The semiconductor wafer consists of two parts,One part is the P type semiconductor, in which the hole dominates,The other end is the N type semiconductor, which is mainly electronic here.

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 different

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.
