Device, scheme of which is shown in Fig. 1. is designed to enable household lighting using any remote control.
Fig.1
The device is next. The signal from the IR remote control is perceived by the receiver of infrared radiation, made on the IC DA1 and enhanced her. As a result, the pin 3 of the IC appears a pack of rectangular pulses. They are detected by executed on a chain the elements R1, VD1, R3. The capacitor C2, together with the resistor R4 form a line the delay, which forms out of the pack of pulses of a single, long duration, which is fed to the input (pin 3) flip-flop DD2.
The trigger included in the counting mode, so each subsequent pulse switches in the state, the inverse of the former. IC DD2 controls the transistor VT1, which commutates the power thyristor VS1, enabling or disabling the power of the pampas HL1. So by the way, a momentary press of any button on the remote control or includes, or turns off the light Should be borne in mind that the incandescent lamp is powered permanent the voltage is rectified using a bridge VD3, so the maximum power the lamp depends on the parameters of the diode Assembly.
The device has a galvanic connection to the AC network, so when adjustment is necessary to observe special precautions.
In Fig. 2 shows a printed circuit Board switch, designed for installation miniature parts. Board made of one-sided glass fiberglass. The most bulky of component parts is a thyristor VS1, but you can replace the small, such as a series of T.
In commissioning the device practically does not need and begins to work immediately after but for best performance it is desirable to select the capacitance of the capacitor C2 on the duration of the pulses sent from the remote control.
