The invention discloses an acoustooptic-controlled time delay circuit, relates to the field of circuit design and solves the problem that existing acoustooptic-controlled circuits are high in cost, short in service life and low in sensitivity. The acoustooptic-controlled time delay circuit comprises first, second, third, fourth, fifth, sixth, seventh, eighth and ninth resistors, a photosensitive resistor, first, second, third, fourth, fifth, sixth, seventh, eighth and ninth capacitors, first, second and third triodes, a diode, a voltage stabilizing diode, a lighting lamp, a microphone, a bidirectional triggering diode, a fuse and 220V alternating current. The acoustooptic-controlled time delay circuit is simple in structure, energy-saving, environment-friendly and long in service life. The circuit is higher than the prior art in sensitivity. When the circuit is in use, devices are less prone to being damaged, the lighting lamp is automatically turned off when there is light in daytime, and the circuit is automatically on when there is a sound at night, so that artificial control is omitted, and the objective of energy conservation is achieved.
Description
technical field [0001] The invention relates to the technical field of circuit design, in particular to an acousto-optic control delay circuit. Background technique [0002] At present, the existing acousto-optic control lamps have the following technical problems: when a fault occurs, the light remains on, or the light is always off, or the time for the light to be turned on is not enough, etc. The biggest reason may be the sensitivity of the acousto-optic control circuit. A large drop, or some components in the circuit are damaged, but it was not discovered in time during the maintenance. If the above-mentioned technical problems occur, the performance of the acousto-optic control circuit may be reduced, power will be greatly wasted, and its service life will be greatly shortened. Therefore, there is an urgent need to develop an energy-saving, environmentally friendly, and long-lived acousto-optic control lighting lamp, which is of great significance to modern home lighti...
