CATHODE LIGHT TUBE FULL

CCFL lamps can be used in applications where a lamp will be dimmed or flashed, unlike most of their hot cathode counterparts. They are also available in screw in spiral form just like “typical” hot cathode compact fluorescent lamps. Cold cathode tubes are also used to backlight signs and LCD displays, they’re probably what is allowing you to be able to read the text on your screen right now, in fact. For many people, the most easily identifiable example of a cold cathode lamp is the neon sign. Where are they used?Ĭold cathode lamps are used in a number of specialty applications. What sets the cold cathode lamp apart is that by using higher voltage, a cold cathode lamp does not require the cathode to be heated in order to fire and produce light. How do they work?Ī cold cathode lamp functions by using electricity emitted from cathodes to excite mercury vapors using the process of inelastic scattering in order to create fluorescence, just as a typical linear fluorescent does. They are known for high efficiency, long rated life, and their ability to start in cold conditions. CCFLs are used in a number of different specialty applications, such as cold-weather lighting, display back lighting, and signage. It’s more convenient for you.A cold cathode fluorescent lamp (CCFL) is a type gas-discharge lamp similar to linear fluorescent or compact fluorescent lamps. Or you can buy it at store near your house.īut…Be careful some point use AC main and high voltage. Then, more other components they look like both circuit before. Read Also: Example Buck/boost converter circuit This circuit looks like a switching power supply circuit. But it has details that may be difficult to understand. Learning a tiny inverter is so interesting. You will see that a high voltage, but so low current. To produce frequencies to drive small transformers, T1. They consist of 6 components, Q1, T1, R1, D1, R1, and R3. It turns 12VDC(input) to 200VAC(approximately). We add the boost up voltage converter circuit. Sure, Xenon flash tube is a good choice.īut before the circuit, we use it with AC main. You want to impress your friends with decorative lights that are not boring. Read next: example use Zerner diode to check voltageĪlso, change R2 to control the speed of flashing.

Same as the first circuit.Īccording to the characteristics of Zener diodes, used as a device to check the voltage precisely. And T1, C1, and I1 emit the highest light. So, it has the current into the gate of SCR1. It causes a voltage of the cathode of ZD1 is more than 12V. We use ZD1(Zener diode) instead of a Neon lamp. You too, right?ĭo you notice the difference? Let’s learn how it works Here is the second, 220V xenon strobe light circuit. C1: 33uF or 47uF 450V Electrolytic capacitor.In contrast, if a high R2, it will blinking slow down.

If low R2 time to charge C2 full or to be 90V is faster. A cathode ray tube utilizes a cathode and anode to create a beam of electrons, which are negatively charged subatomic particles that were discovered through the experimentation with cathode ray tubes.

It works repeatedly like this, so we can see the I1 blinking in a continuous rhythm. And when the voltage of C2 rise up until NE1 can conduct current. Then, C1 start to charge new again and C2 too. We will see the most light in one time and then stop. So the whole energy of the C1 is emitted to L1 with all. It ionizes Internal gas to conduct electricity. These pulses activate the Xenon Flash Tube. This produces a high voltage pulses is thousands of volts in a short time. It causes electromagnetic field induction to Secondary winding of T1. It is a type of step-up voltage transformers Though small but it can increase the high voltage at primary winding. Then, the electric charges in C2 discharge through SCR1 and primary coil of T1. So, it has the current to the gate of SCR1. And, it will flow through the Pri coil of T1. Then, R1 reduces a current down to charge in C1.Īt the same, some current flows to R2 to charge C2.

Do you want to see more circuits? to understand how it works. Therefore have to store energy first And then released at once.Īfter that, the circuit will gradually keep electricity before releasing it to it again. Since we want It emits maximum light only for a short time. Therefore having to feed thousands of volts pulse signal to a high voltage trigger terminals too. (Positive Anode and Negative cathode) Then, It ionizes the gas into light energy.īut we need the light energy to come out quickly as needed. When there is a high DC voltage across both lamp terminals. Inside the glass tube containing xenon gas. Let me explain to you how it works in a simple way. Look at the basic structure of the Xenon Flash tube below. Related Posts Meet Two Xenon Flash Tube Shape
