Disadvantages
- Kerosene lamps pollute the air, which can lead to health problems
- Glow bulb lamps lose a lot of energy while producing heat
- LED lighting is not as energy efficient as fluorescent bulbs and tubes
- Energy saving fluorescent bulb lamps have a short life and cannot handle vibrations and are expensive
- Standard fluorescent tubes have a long life and are energy efficient
- Fluorescent bulbs and tubes have a thyristor in the electronic ballast
- This thyristor spoils a lot of energy producing heat
- The base or outlet end of the fluorescent lamp has two filament coils
- These coils spoil a lot of energy producing heat
- Heat attracts and kills insects
- These transistors cannot light a match
- Cold cathodes out ends do not heat up
Advantages CCFL
- This makes the CCFL lamp very use full to use in poor areas
- The ballast of a CCFL lamp has two transistors instead of a thyristor
- The CCFL tube lamp has cold cathodes instead of filament coils
- Because the CCFL does not heat up like a TL lamp, the CCFL uses les energy than the TL lamp
Importance of Lamp Cap with the following benefits:
-Energy efficient
-Protected against falling from heights
-Protected against vibrations
-Protected against impressions
-Water and insect tight
-Acceptable design
-Easy to adjust in any direction
-Inexpensive
-Can work on low plus and min (DC) voltage
Disadvantages CCFL
The mercury in the tubes
How to
You can use a CCFL and electronic ballast out of an old SCSI document scanner. Just so you know a ballast is the same as an Inverter. Also not all scanners have CCFL technology the new ones have LED technology and very old black and white faxes have LED technology. You may be lucky enough to find in some scanners a separated CCFL inverter circuit board.
WARNING the CCFL inverter has a dangerous high voltage output
Instructions:
- Make a drawing of the electronic schema
- Some times you can find a circuit board with the CCFL inverter electronics and some scanning electronics.
- You have to separate the scanning electronic parts
- Cut of the CCFL ballast unrelated electronic
- Now it have the right shape to use this inverter to light up the CCFL lamp.
- It is possible to use a CCFL inverter in combination with a normal fluorescent tube lamp
CCFL lamp and ballast out of a fax machine
It is possible to use a CCFL and electronic ballast out off an old fax machine, however some fax machines have a colored CCFL tube
- In some colored CCFL tube faxes it is possible to take the colored film off
- Some colored CCFL tube faxes have colored glass, then the tube is useless for the lamp cap
- The CCFL tube is in the paper scanning part of the fax
- CCFL ballast is connected with the CCFL tube
- Not all fax machines have CCFL technology
- New fax machines and the very old fax machines have LED technology
