- No contact of the wire with the plug
- Switch does not work
- Broken wire
Repairing a lamp is not difficult, but for some reason its repair is often postponed indefinitely. The reason for this may be unsuccessful searches for a breakdown, which may never be crowned with success. Consider the main reasons for the failure of lamps and how to troubleshoot.
So the lamp went out. Where to begin? Most likely, the lamp has burned out. To replace a lamp, you need to know the size of its base (E14, E27). The lamp must not be removed while it has cooled down, as the bulb may come off the base, which will then be very difficult to remove. Before screwing in the lamp, it is important to make sure it is working properly..
If a new screwed-in lamp does not give the desired result, look at the contacts in the socket. Perhaps they do not touch the base, respectively, there is no power. To do this, use a screwdriver to bend the contacts so that the screwed-in lamp touches them.
Further, there are more laborious processes of lamp repair. The main reasons for the lack of voltage in the cartridge can be:
- No contact of the wire with the cartridge.
- No contact of the wire with the plug.
- The switch is broken or there is no contact of the wires with the switch.
- Broken wire.
In order to verify that the problem is in the power circuit, you need to use a tester or multimeter. It is worth checking the entire circuit, as well as its individual sections: from the plug to the switch, from the switch to the cartridge, the switch itself. Let’s consider each of the cases separately.
No contact of the wire with the cartridge
The whole difficulty of repairing a luminaire in this case lies in the fact that it is necessary to disassemble the entire structure of the luminaire. This must be done carefully so as not to break its fragile parts. If an old-style cartridge was used in the lamps, then it is better to replace it with a new one, since over time it has dried out and may crumble.
Having reached the cartridge, we check if the wires are fastened with screws. Please note that the life of your lamp depends on how well you attach the wires. Therefore, it is recommended to attach the ends of the wires, in addition to the screw connection, additionally by soldering. In addition, the wires in this place often give in to bends, so it is recommended to put on a piece of rubber hose or tubing.
No contact of the wire with the plug
One of the weak points in the luminaire is the wire at the entrance to the plug, which usually breaks down due to frequent bends. In this case, the plug is cut off and a new detachable plug is put in its place. Before installing a new one, pay attention to the diameter of the plugs of the old plug. As in the case of connecting the wires to the socket, it is advisable to solder the wire to the plug to ensure a reliable connection. The wire should fit tightly into the plug, so if the diameter of the wire is not enough, you can add a thick elastic band, electrical tape, or use a braid from the same wire.
Switch does not work
We disconnect the switch and use a multimeter or tester to check its operation. In the first position, it should not transmit an electrical signal; in the second position, it should. If it is not, then it is out of order. In this case, a new switch is bought. You can also make a lamp without a switch by connecting the wires directly. In this case, the lamp will be lit by direct plugging into the socket..
One of the signs of a broken wire is that the lamp flickers when you move it. Replace this wire with a wire with the same cross section, but not less. Ideally, a wire with a cross section of 1.5 mm is used2. If there are places where the bends of the cord turn out to be very steep, you can put plastic or rubber tubes that will limit the diameter of the bend of the wire, thereby prolonging its life..
When assembling the luminaire, you must make sure that all parts are firmly fixed, nothing dangles. The wire inside the luminaire must be free and fixed at the exit from the luminaire. It is not recommended to use wires made of two different metals (copper and aluminum), as their twisting will oxidize over time. Plus, aluminum will break quickly. If all of the above is done correctly, the next repair of the lamp will not be soon..
