Many faced the problem of the frequent failure of the light bulbs in residential areas, especially in remote places. This may be due to several factors.
Such as power failures, seasonal temperature fluctuations, manufacturing defects, human error and many others. This article describes a simple and relatively affordable way that will extend the life of incandescent bulbs.
Preparatory work and materials
- The semiconductor device - diode 1N4007.
- Plastic squeeze connection.
- voltage indicator.
- Screwdriver.
For ease of installation at the installation site, it is necessary to cut the terminal connection into two parts, with one two-way contact.
installation diode
Install a diode is recommended in a free cavity in the wall where the switch when it is set to the built-in performance. Or the inside of the body, with the burden of (external) type.
To do this, partially dismantle the switch. These works must be performed without touching the wiring line disconnect if not possible (in the hallway, for example). Pre putting off switch to the off position. Then indicator determines which terminal phase switch is supplied.
Further, on the opposite side from the phase disconnect end of the wire on which no voltage is applied, and fasten it to the prepared compound of the terminal.
On the other hand terminal diode anchoring compound, given that the strip on the body diode, indicating a cathode side was compound. A free end of anchoring diode to switch terminal.
It should be noted that the diode is attached close to the transition and connection terminals of the switch, to avoid a short circuit.
After reliable diode fixture mount the switch in its place. Further, with the switch; Ideas in food chain. Upon successful installation of the bulb lights up. In this case, it is possible to observe faint flicker.
Note: If you work without disconnecting the voltage at the installation site, you should be careful! Touch to the wire, which is fed by phase may cause an electric shock!
conclusion
After you install the diode will change some characteristics of the current movement in the chain that will extend the life of incandescent bulbs. The described method is not recommended for areas of frequent and prolonged human use, as characteristic of the light flux may negatively affect vision.
