How do you test a fluorescent lamp for performance?
Title: Luminescent 
Fluorescent lamps and ce use cato basically brightening behind flocks. Fault lead to insufficient lightening, slip on comfort on the spot. Brmcheneto for a defective lamp is annoying. Trepkaneto on the lampata is an exception to the possibility of labor activity, affecting unfavorably on vision. First, continue with the elimination, it is necessary to clearly and understand the principles for work and, yes, you know, admit to troubleshooting on the component on the construction.

Principle for action
A fluorescent lamp, based on the principle of operation, all of which is related to gas discharge from a light source. Stiklenata trba e plna from the livestock bet and inert gas. Electrodite sa grades in opposite edges. Dalzhinata on the lampata can be yes varia. In the mode on the starter between tyah vznikva dha, some drive until you appear for ultraviolet radiation. That one, the action of the top of the phosphorium layer, which is a crooked surface on the surface of the krushkat, I am a car and shine into the vision for the horata spectrum. In the operating mode, the discharge is supported by electricity from the electric current from the cathodic niche. The light layer can be with different colors.
The lamp works in two modes: ignited and light. Illumination was the object of osiguryava theses of the state. Negative electrical circuit e is shown in figure 1.
Figure 1
Illuminate bodies from a new generation using electronic ballast. The g23 cruiser is compact in size and saves the driver and is enclosed in a heavy weight. Those sa are three types, but all the time, the regime for work is defined, and there are four from tyah:
- included;
- pre-polluted;
- zapalvane;
- outcasts.
Thank you for choosing the right modes for work, such devices keep the stomach on the lamp and have a high efficiency. In the mode on fire, the voltage on the electrode, in any case, allows for lampat and work with burnt out cathodes of the spiral, which is impossible when using a standard overwire.

Please call the fluorescent lamp first, you will recognize it and cause possible malfunctions.
Protect fluorescent lamps from burning out
Damaged fluorescent lamp
The electrode behind the fluorescent lamp is in the direction from the tungsten niche. In time, at the beginning, they heat up strongly on the izkhvarlyaneto and, as a result, they burn out on tov barzo. For this purpose, the stomach is exploited, the tungsten niche is covered with a layer of active alkaline metal. Tova stabilizes the luminous discharge between the electrodes, therefore not getting very warm and intact on the electrode for a long time. As a result, a lot of switching on, gradually breaking down and disintegrating. Discharge preminava self prez golata often on spiralata. Point-to-point heat up, drive until he’s ready to go out of harm’s way. The standard scheme on the cabel, some of the throttle and starter, yama and turn on such a lamp. The pipe was not shaking but it was damaged. This is the main condition, for some reason not allowing lampat and burn out prematurely.
Suspended on a malfunction and suspended on a malfunction
A fluorescent lamp is a complex device. Malfunction on any of the wrong elements can be brought to a malfunction.
Those can yes they will appear like this:
- full lipsa on the confession on the inclusion;
- briefly blinking on the lamp, followed by turning it on;
- inexpressibly treptene without inclusion;
- Instantly in the mode on izgaryane.
Integrity on the spiral electrode
How to call the fluorescent lamp is shown in figure 3.
Fig. 3. Ringing on the electrode
For yes, send a tov, you can yes use a multiset. Suitable and a screwdriver with an indicator behind the seal on the verigata.
The switch ring on the multimeter is set to the position for the resistance measurement. It is necessary to select a ni-niskat border on the measurement (Ώ) or put the switch in the position for checking for a constant sound signal. Tie the measuring cables and wire them to the electrode. Call the lampat. Sound alarm or instrument readings, different from bezkranostt, showing the integrity of the spiral. You will pervert like actions from the second spiral. Ako monitor on the device to show the state of "chupvane" or sound a signal, do not turn it on, the lamp does not work all the time. You can, yes, experiment and “light up” in the ballast of a lamp.
For checking on the electrode, you can use a screwdriver, with a function for ringing on the verigat. Verigata "1-wire electrode conductor - screwdriver - a little bit - 2-electrode conductor" tryabva and ring, in this case, the LED indicator, which is embedded in the tester, is brighter. Tryabva yes check and dvete spirals. Lipsata on the indication on the pony is a single electrode showing a malfunction on the lamp.
Malfunctions in the electronic ballast
Attention! It was taken away and tied up to the ballast of the kum mrezhat without natovarvane, the device can be burnt out.
Determine the correctness of the ballast, which is equipped with a fluorescent lamp, and you can connect the cap with a pressurized button with a power of up to 60 watts, remove the contacts. Tryabva yes shine weakly.
Electronic ballast is a complex electronic device. Checked and repaired on the electronic circuit of all distortions with the help of a special device, a kato oscilloscope.
Contrary to Comrade, nay-chesto cross-functional faults can and be removed without crawling. Figurata showing one from the diagram for the ballast.
Figure 4. Electronic ballast.
Predpazitelyat, out of the capacitor and the transistor often fails, those are the indications on the figure.
For yes, check the predazitel correctly, the one is drunk from the verigata. Integrity is determined from the tester. Indications for the device are shaking and all are different from bezkraynostta.
The operating voltage on the electrode from the ballast may be out of the range of 500 V. Chinese manufacturers install capacitors, which have a border on the nominal voltage, which is 400 V itself.
The price on the transistor is immeasurably lower than the price on the new ballast, so I crawl from experience for crushed by it.
Attention! For the operation of the verigat in the normal mode, the nominal voltage on the capacitor is 1.2 kV.
How to check the drosela on a fluorescent lamp
How do you check throttles
Faults on the throttle can be cut in the pre-winding on the winding or the connection between the curls.
Tryabva and determine whether to stop with a multiset, a screen on a device or an arrow (depending on the type of device) in the mode on a resistance measurement, even if it shows no extremes.
When you close the gate, the readings are still close to "0". You can recognize the burnt out drosel according to the Mirismata on the burnt out; according to the weight, kafyawi petna appears, showing some significant damage to the device.
A defective throttle can not be corrected and the trebva can be replaced. Whenever you install new ones, try and pay attention to the labeling. You tryabva and answers to the power on the lamp.
How do you check the starter
For a malfunction on the starter, you can go on the fact that when you apply voltage to the lamp, it’s a moment, but not light.
If the starter is not switched on in the verigata on the lighting rod, do not turn on the opening contacts. Nyama and work and check the correctness of the mu with the multiset. You can bend the chain, in which the starter is connected in series with a lamp with a pressurized switch with a power of 60 watts. If the starter works correctly, then the lamp will burn out more and the next period is determined from the time and brightness to the brightness.
Figure 5. Scheme for testing the starter.
How to check capacitance on a capacitor with a tester
Capacitor, installed between the conductors on the source on the storage, without directly affecting the operation of the lighting rod. It is necessary to provide a reactive power compensator for the throttles. Lipsate or a fault on the capacitor leads to the fact that the effectiveness of the cyalate wire is about 40-50%. Not enough. When the capacitor is operating, the efficiency is still more than 90%, the paints are consumable for energy.
For lamps up to 40 W, the rating for the capacitor is yes, but it is limited to 4.5 μF. Painted on the capacitance and brought it to the paint on efficiency, it can be increased and brought to treptene.
You can check the correctness of the capacitor from the device, which has a tasi function.
Switching on a fluorescent lamp without inductors
With a temporary fluorescent lamp dory in hi-modern, the illuminators of the body will burn out. Contrary to Tov, tyakhnata work can be done. Vvverigite for the connection to the burnt out lamps without throttles and the starter is constantly under pressure. Nay-forgive the chain type for such an insertion of a current converter with doubling the voltage from the full wave. Over time, the flow becomes lighter and weaker. In advance, install, if necessary, screw the lampat into the lighting body (change the connection of the column).
Scheme on the connection to the burnt out lamps
Figure 5. Fully doubled current rectifier.
At the moment on the starter, the voltage on the capacitor and the diode is up to 900 V. With such a nominal value, the trap will be allowed to select electronic elements.
Izkhvarlyane
Fluorescent lamps for betting gum. Izkhvarlyaneto them with a bit of otpadatse taken away. Vsichki legal entities tryabva yes imat agreement for razrezhdane with a licensed organization.
