We often hear reproaches about premature burnout bulbs. And although they mostly fair, I'm pessimistic not going to join. Because the solution of this technical problem can be found even in a home workshop.
In particular, their bulbs in the kitchen, in the hallway, closet and bathroom I include not directly, but through a diode voltage converters. Made sure that the lifetime of the light sources when such exploitation is increasing in many, many times, as the reliability of the lamp grows mainly at the expense of nedical the tungsten filament passing through it "half-wave" power.
To embed diode-economy in the circuit are usually used available niches switches, special adapters, and even the lamp base. But in all these options require semiconductor valves, designed for maximum direct current I max and the maximum reverse voltage iobr.max. Here complexity.
So, a low-power diode DB works perfectly paired with a 60-watt lamp. But he clearly "pull", when electroputere screw up a lamp power of 100 watts. Hence, the desired semiconductor medium power valve, but it costs more any D226.
Offer your own version using a semiconductor Assembly diode bridge, which has at least one shoulder properly. For example, a well suitable for these purposes widespread odnomernye CCA, CCB, CCW, CCH and CCD with iobr.max, respectively, 500, 400, 300, 200 and 100 V.
The size of the diode bridge is slightly less than the terminal block and to embed it easy to find extra space. You can all hide in the hood that hides the hook pendants lamps.
In this connection, any bulb does not burn out long even in the unstable electrical (insulation in the form of PVC pipe conventionally not shown): 1 - a lamp holder; 2 - "chandeliers" terminal block; 3 - diode bridge series KTS402 in the body; 4 mounting wire
For mounting of semiconductor of the "stop-the economy need to the pins healthy shoulder solder bridge along a section of copper wire with a length of 50-100 mm and cross-section of 1.5 mm2. To wear them (to avoid accidental short circuits) PVC pipe and connect to the terminal block on the one hand, and with another podsticati neutral wire and either of the two pins with electroputere lamp.
The remaining output electroputere need to connect the wire from the switch and to isolate this place. If the connection cable is not desirable (especially when contact electrocorrosion pair type copper-aluminum), more acceptable standard "chandeliers" block with three terminals.
Of course, the installation still executed only when de-energized network!
