THE CHANDELIER IS CONTROLLED BY THE DIODE

THE CHANDELIER IS CONTROLLED BY THE DIODEChandelier, sconce or a floor lamp in every house. They often burn on several lamps. Do I need it? Not always. And here is the owner of such a lamp becomes involuntary “waster” of electricity. But only because turning off “unnecessary” lights are not available. However, you can add a third wire. But in flats with concealed electrical wiring immediately raises a problem: where to spend it. And that’s where the master comes home… diode.

 
Look at the circuit shown in figures 1 and 2. The diodes in them are the kind of valves which, using a conventional two-wire network, you can control the light in the chandelier. Diodes located in the left part of both schemes, establish inside the switch, and those that are shown on the right — directly at the chandelier.
 
When you turn on S1, the LEDs H1 (Fig. 1) or N2 and NC (Fig. 2). As in the circuits of their power included the diodes, the lamps consume half the power and therefore Shine dimly.

Even if you include and S2 in the circuit of the lamp N2 and N3 will burn half the power, and the lamp H1 is in full force. In the second scheme, half of the power consumption lamp H1, and in full force burning H2 and H3.
 
Figure 3 shows a complicated control circuit for the light. In it, the switch S1 is secondary (neutral) position, in which the chandelier is completely off. With two-pole switches S1 and S2 (switches) can include one, two or three lamps.
