Q:LED energy-saving integrated fluorescent lamp tube with four interconnections in the middle
The integration of tubes: mainly in the traditional lamps and lanterns, also is the T5 trichromatic lamp, as a result of the three primary colors T5 tubes need rectifier, and trichromatic lamp life is limited, the designer in order to facilitate the rectifier and convenient replacement bulbs, use of integrated design. Now the LED lamp just began to enter the market, many companies also modeled on the traditional lamps and lanterns to design
Q:The LED fluorescent tube plus the ballast why is it still going to press?
Use neon bulb discharge heating bimetallic strip in open and close, cause inductance ballasts and generate high voltage pulse electric current mutations on both ends of the lamp and ballast used in fluorescent originally when the above is to make haste to booster.
Q:Can normal LED fluorescent tubes be used in a vacuum?
Both kinds of light-emitting device itself can be used in vacuum environment. But they alone is difficult to work and need to match the other electronic components and circuit, LED to match driver circuit (); Fluorescent lamp or fluorescent lamp should match the inductance ballast or electronic ballast circuit components, such as ability to work, some of these additional circuits and components can work in a vacuum, some components may not be suitable for vacuum work, some will spread in a vacuum, could destroy the vacuum environment, some hot components in a vacuum, also not easy heat dissipation
Q:The reason for the slow start of an old-fashioned daylight tube
The old fluorescent lamp is used to heat the filament of the lamp with the light of the regenerator, and the ballast produces high pressure when the regenerator disconnects
Q:The T8 nominal 36W standard daylight bulb is only 18W
Do you know your own design is what reason. Now in the market is almost not not qualified fluorescent lamp, fluorescent lamps (CFL) so I said is rubbish products. By doing a lot of LED torch is take waste products such as the contrast of the object, in fact only take the LED of the measured power and comparison of the nominal power of the fluorescent lamp to do, just can have what 18 w instead of 40 w theory and practice,
Q:Help me see the yellow on the left side of the LED fluorescent lamp
The yellow one is the gauge capacitor, the first element on the left is the NTC resistor, the third component is the inductance, and the two components behind the inductance are the electrolytic capacitors,
Q:Why don't leds need a rectifier
Because LED is a direct current is needed to light, and the output voltage of rectifier is an alternating current, so can't use rectifier, now LED lamp is built-in power inside, and use it every time you'd better put fluorescent original rectifier and demolition of the starter, but given the easy to use, now LED lamp can be directly on the original fluorescent lamp holder, do not need to disconnect the rectifier, only need to send a link of the starter circuit cut. Because the regenerator will provide an instantaneous high voltage, it will damage the LED
Q:How do you measure the flux of the LED fluorescent tube
In theory, it's measurable, and it's actually hard to set up. There are two ways of measuring flux, essentially the same thing 1: the integrating ball is measured by your illuminometer 2: set up the field aperture + your illuminometer + space station to measure by the 4PI () stereo Angle integral. The last time you said you have integral ball and light meter I suggest the first way is feasible. In addition you put not fluorescent lamp it doesn't matter, can be measured in area of block of luminous flux, and finally take the area integral. The results must be less than professional distribution photometer to measure, the standard but the data still have rigorous theory and process support.
Q:Ordinary fluorescent lamp ballast can be replaced with led daylight lamp tube
The fluorescent lamp tube changes LED lamp tube, need to change the line, remove old ballast and the generator, connect the power directly, because, the LED lamp tube has the power source inside.
Q:But what happens when you don't take a ballast and replace it with a traditional fluorescent lamp?
This can also be bright, but it's also a waste of electricity and some of it doesn't have a flash of flash and it's going to light up in a flash
