When the utility model adopts remote controller to carry out readiness and shut off at television set, can send voice suggestion, the prompting user cuts off the electricity supply electrical energy saving.This apparatus structure is simple, make easily, steady quality, safe and reliable, each device are not easy damage, long service life and with low cost, can effectively improve user's saving consciousness, for energy savings is made significant contribution.
Description of drawings
Fig. 1 is an electric functional-block diagram of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Mark is as follows among the figure: photoswitch circuit 1, sound circuit 2, amplifying circuit 3, loud speaker 4, power supply 5.
Embodiment
The utility model is installed in television set standby indicating lamp place, and under the electrical equipment normal operating conditions, its standby indicating lamp does not work, and this device is in off position, not consumed power; When electrical equipment began standby, standby indicating lamp was bright, and this device is accepted the light signal of standby indicating lamp, and light signal is converted to corresponding pulses voltage, thereby trigger switch is started working loud speaker, made the thorough powered-down switch of its reminds people of sounding.
Show among the figure that the utility model is made up of photoswitch circuit 1, sound circuit 2, amplifying circuit 3, loud speaker 4, power supply 5.
Show among the figure that photoswitch circuit 1 comprises photovoltaic power source switch and light-operated trigger switch two parts.
The photovoltaic power source switch is connected to form by phototriode VT4, mains switch SA, power supply BT.Energized switch S A, when television set was not in holding state, its standby indicating lamp did not work, and this moment, phototriode VT4 optoelectronic switch can not be closed, and circuit is not worked, and installs not power consumption.When the standby indicating lamp of television set was bright, the irradiate light of standby indicating lamp was to the surface of phototriode VT4, and phototriode VT4 connects, main circuit work.
Light-operated trigger switch is made up of phototriode VT1, triode VT2, resistance R 1, R2, capacitor C 1, potentiometer RP.When the standby indicating lamp of television set is bright, the irradiate light of standby indicating lamp is to phototriode VT1 surface, phototriode VT1 two ends equivalent resistance can increase suddenly, thereby cause phototriode VT1 two ends to produce corresponding pulses voltage, its trailing edge is coupled to triode VT2 base stage through capacitor C 1, after the anti-phase amplification of triode VT2, make the TG port of sound circuit chip A obtain a positive pulse triggering signal.In this circuit, potentiometer RP is a light trigger sensitivity regulator potentiometer.
