Scheme without Transformer Tube Lamp Ballasts


On this occasion I will discuss about how to turn on the lights or fluorescent lights which is often called the TL. We often call it TL, maybe one of you ask - ask what exactly it stands for TL. Ehmm .. just think for a moment ....!!
Lamp TL stands for "Tube Luminescent", there is also a call to the "Tube Lamp" are also called fluorescent light bulbs or tubes. We repeat the lesson a little while junior that fluorescent lamp is a lamp shaped vacuum tube on each end there are 2 pairs of wire filament (coil) that the principle works like a standard incandescent bulb, which is the difference in this light is inside the tube is injected with mercury and argon gas at low pressure, when the electric current flowing electrons will move from one end to the other end of the tube. Electrical energy is also changing from a liquid to a gaseous mercury that mercury atoms at the same time in the form of gas will be hit by electrons. This causes the electron collision energy increases. When the electron energy back to normal then releases electrons that light energy into light. To turn on a fluorescent lamp ballasts shall be necessary and strarter. For it was on this occasion I will be creative how to animate without using ballast fluorescent lamp and starter. You may ask - ask and certainly think long and grumble >> It's not possible!!! and I would say >> It probably :-).
Previously we air-experiment let us see the basic scheme turned a fluorescent lamp that is used by people in general.

"LAMP BASIC SCHEME TL"
 
From the above scheme can be concluded that the transformer ballast only limit the current flow and adapt to the characteristics of the lamp. While functioning as a starter at the beginning of starting ignition as an early startingnya fluorescent lamp requires a high voltage of approximately 400 volts to heat the gas in the tube electrodes that can berpindar.
To prove my conclusions above you can create a series of substitutes that can easily get in the market and electronics store close to where you live.

The materials you need to prepare are:

1. Capacitor 330 nF / 400 Volt
2. Resistor 680K measures 1 Watt (blue, gray, yellow)
3. Resistor 100K measures 1 Watt (brown, black, yellow)
4. Resistor 56K 1 Watt size (green, blue, yellow)
5. 100 ohm resistor size 5 Watt (Resistor Model Kapur)
 
After you prepare the components above, and then make the circuit as shown below:

If the circuit according to the image above make sure to be careful when menyalakanya, away from grounding / land, because if you create a series that would result konsleiting sloppy.

Black Light

This circuit is a simple ultraviolate light that can be powered by a 6 volt battery or power supply that is capable of supplying 1 or more amps.
