Can the life of fluorescent lamps reflect the quality of electronic ballast
All the life of the fluorescent lamp can't response performance of the electronic ballast, for example: when the fluorescent lamp tube voltage, filament cold resistance, vacuum degree, cannot meet the requirements, it is easy to black and failure. Electronic ballast for tubes provide start-up voltage, preheating current, as well as the work of the tube current, voltage, cathode current, wave ratio, and the glow time, these have decided the lamp life and can be used to switch on and off the number of times.
And then the daylight tube. Fluorescent tubes have been used for decades in our country, so far, we can get the remains of preheating type fluorescent tube, whether early T12, or late T8 and T5 T4, even all type preheating tubes, and were not marked on all tubes is frequency fluorescent lamp or fluorescent lamp. , of course, has made great progress in recent years the quality of our fluorescent tube, single filament, it experienced a common single spiral filament, the double helix filament, triple helix filament even more helical filament. Phosphor powder is also widely used in the use of rare earth tri-color phosphor powder, which greatly improves the efficiency and longevity of rare earth. But, as stated earlier, don't have preheating function of the electronic ballast to drive the need to preheat start of daylight lamp, the lamp can exert the best working state all too clear. The life span is naturally shortened.
The vibration of the elevator has little effect on the life span of the fluorescent tube and electronic ballast, and the effect on the incandescent lamp with filament is greater
Working principle of the electronic ballast is simulated inductance ballast, electronic ballast fluorescent tube short life generally, so in general lamp life can reflect the quality of the ballast
