Description
Technical field
The present invention relates generally to sound-optical controller, is specifically related to high power capacity and electric resistance dual-purpose sound-optical controller.
Background technology
The Sound and light control switch of selling on the current market can only be controlled low power resistive load, for example, and common electric light.But can not control powerful capacity load, for example, the fluorescent lamp of a plurality of parallel connections.
Some electric currents are also arranged at the high-power Sound and light control switch more than 1 ampere on the market, this high-power Sound and light control switch all is that contact endurance is short with relay output.If be used for the high power load of control capacitance, for example, runaway condition usually appears in the fluorescent lamp of a plurality of parallel connections, and many fluorescent lamps are light yellow still by day.Cause energy waste.
For the shortcoming that overcomes above-mentioned existing Sound and light control switch proposes the present invention.
Summary of the invention
The purpose of this invention is to provide a kind of high power capacity and electric resistance dual-purpose sound-optical controller.
High power capacity of the present invention and electric resistance dual-purpose sound-optical controller adopt controllable silicon noncontacting switch and control circuit, design independently power supply; When being used for the control capacitance load, for example during the fluorescent lamp of a plurality of parallel connections, add dummy resistance R17 (the resistance value scope is 22K Ω ~ 51K Ω) at output, in the controlling resistance load, during for example common electric light, then need not add dummy load.Therefore, fall for a short time by the switching voltage of high power capacity of the present invention and electric resistance dual-purpose sound-optical controller, service time is short, and response speed is fast, and is contactless, voiceless sound, long service life.
By high power capacity of the present invention and electric resistance dual-purpose sound-optical controller, photo-resistor and white high brightness LED (LED) have been adopted.Day on daytime is diminished by sun-exposed photo resistance internal resistance during light intensity, and light control circuit is disconnected, and white high brightness LED (LED) disconnects and not luminous.Because light control circuit disconnects, therefore there is not output signal, the sound control circuit part that is positioned at the light-operated circuit portion downstream does not start.So, the controlled load on daytime, for example fluorescent lamp cuts out, and is not luminous.
Do not have in the sun-exposed environment to night or at other, be not subjected in the sun-exposed photo resistance resistive big, make the light control circuit conducting, white high brightness LED (LED) conducting and luminous.When sound being arranged in by high power capacity of the present invention and electric resistance dual-purpose sound-optical controller surrounding environment, the audio-switch in high power capacity acousto-optic of the present invention of the sounds trigger in the environment and the electric resistance dual-purpose controller, for example, microphone; Sound control circuit in high power capacity of the present invention and the electric resistance dual-purpose sound-optical controller partly starts, after the bridge rectifier rectification of output signal through the output in high power capacity of the present invention and the electric resistance dual-purpose sound-optical controller of sound control circuit part, output voltage is added in check load.For example on the fluorescent lamp, start the fluorescent lamp luminous lighting.
High power capacity of the present invention and electric resistance dual-purpose sound-optical controller effectively controll day light modulation and common electric light.Fluorescent lamp is under not alive situation, two impedance between electrodes are infinitely great, therefore, be called capacity load, high power capacity of the present invention and electric resistance dual-purpose sound-optical controller add the dummy load of a parallel connection at output, therefore high power capacity of the present invention and electric resistance dual-purpose sound-optical controller are in parallel with in check fluorescent lamp, and at fluorescent lamp not during making alive, the impedance at fluorescent lamp two ends is substantially equal to the impedance of dummy load.The voltage drop at fluorescent lamp two ends equals the voltage drop in the dummy load.Thereby high-power sound-optical controller of the present invention becomes the high-power sound-optical controller of capacitive character.When controlling common electric light with high-power sound-optical controller of the present invention, not during making alive, the impedance of electric light equals the filament impedance at electric light.Therefore, high-power sound-optical controller of the present invention does not add dummy load and becomes the high-power sound-optical controller of resistive.So, high-power sound-optical controller of the present invention be can the control capacitance load again can the controlling resistance load dual-purpose high-power sound-optical controller.It is little that high-power sound-optical controller of the present invention has overcome existing lamp controller power, can not effectively control the shortcoming of the fluorescent lamp of a plurality of parallel connections.
