Intelligent remote-control contact light-modulating switch

Abstract

A switch is featured as connecting touch plate with gate circuit, outputting weak electric signal generated by touth plate after being wave pared, amplified and rectified through the gate circuit from MOS level; connecting the gate circuit to single-chip computer, connecting reference signal circuit with the single-chip computer, connecting infrared receiving head with the single-chip computer which generates a control signal after calculating MOS signal or electric signal sent by remote control signal receiving circuit with the reference signal; sending it to signal amplification circuit connected with the single-chip computer and control electrode of two-way silicon control to realize on-off or phase variation control and connecting two-way silicon control with load in series to control voltage transforming circuit to export control voltage of +5V and +10V.

Description

technical field [0001] The invention relates to a switch, in particular to an intelligent remote control touch dimming switch which uses a single-chip microcomputer to control a bidirectional thyristor to realize non-contact control of power supply on, off and dimming. Background technique [0002] At present, in the aisles of buildings, touch-type time-delay switches are very popular, and it is also very common to use dimmer switches to control the brightness of incandescent lamps in homes and offices, but these switches still use contact switches, that is, The on and off of the switch are all realized by opening and closing the switch contacts, and the realization of dimming is realized by adjusting the output voltage of the transformer. This way of adjusting the output voltage through metal sheets or transformers is not only easy to cause ignition and arcing of the switch, but also the metal joints are prone to aging after long-term work, and the contacts are in poor cont...

AI Technical Summary

Problems solved by technology

This way of adjusting the output voltage through metal sheets or transformers is not only easy to cause ignition and arcing of the switch, but the metal joints are prone to aging after long-term work, and the contacts are in poor contact. The service life of dimming and switching is not long, and it is easy to damage

At the same time, due to the use of contact switches, if remote control operation is to be realized, the structure is often complicated, and electrical components such as contactors are needed, and the performance is unstable.

At present, the voice-activated switch used in some high-end places requires a special central control machine due to its complicated equipment structure, and the user invests a lot, and it is difficult to popularize it in homes and general places. These all limit the popularization of remote control dimmer switches.
