Abstract
The utility model for switch and brightness control relates to a switching circuit for lamp brightness control provides a switching circuit. The technical proposal of the utility model is that a non-polar capacitor is in the state of series connection in a double-switching circuit. When a non-polar capacitor with proper parameters is in the state of series connection, an incandescent lamp or a florescent lamp has the statuses of daybreak and twinkle. When the double-switching (K1) bridges switch (2), the current from terminal enters 2, then 3. Once the connection between 3 and 4 is cut, the current enters 3, then 4 and finally the lamp L, at this time the lamp is bright. When 3 bridges 4, and the connection between 3 and 5 is cut, the current from 3 enters 4, then capacitor C, and finally 5 and lamp L, at this time the lamp emits gloomy light. Thereby, the switch circuit in the utility saves energy and is durable when it is cooperatively used with a lamp.
Description
Technical field
The utility model relates to a kind of switching circuit of controlling lamp brightness.
Background technology
In actual life, though used potentiometer switch has open and close and dimming function, can only be used for incandescent lamp, be not useable for adjusting brightness of fluorescent lamp, also damage easily.
Summary of the invention
The purpose of this utility model is to provide a kind of can make the switch switching circuit of tunable optical again.
The technical solution of the utility model is: electrodeless electric capacity device of serial connection in the ganged switch circuit.
Use the utility model, can with incandescent lamp, fluorescent lamp adapted, and have the effect of switch lamp, lamp is reached cover bright function, play the durable purpose of power saving.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the ganged switch circuit diagram;
Fig. 2 is a circuit diagram of the present utility model.
Embodiment
Two keys of tradition boxlike ganged switch are controlled separately that a lamp puts out or are bright, as shown in Figure 1.Fig. 2 is made up of suitable electrodeless electric capacity device of parameter of a ganged switch serial connection.When the suitable electrodeless electric capacity device of parameter of serial connection, just can make incandescent lamp or fluorescent lamp have the bright or bright function of illiteracy.Electric current enters from terminal, and when ganged switch K1 and 2 disconnections, lamp does not work; When ganged switch K1 and 2 connected, electric current entered 2, to 3.If 3 and 4 disconnect, electric current is from 3 through 5 to lamp L, and at this moment lamp is shinny.If 3 and 4 connect, 3 and 5 disconnect, and electric current is from 3 through 4 to capacitor C, and again through 5 to lamp L, at this moment lamp produces and covers bright effect.Because the electrodeless electric capacity utensil has the performance that reduces voltage, electric current also diminishes thereupon, so lamp is just not as bright originally.When 1 and 2 connected, 3 and 4 were switched on or switched off, and 3 and 5 also disconnect or connection thereupon simultaneously, and bright or bright effect just appears covering in lamp.Therefore, be connected in series the capacitor of different appearance values, just can change the brightness of lamp.Like this, the utility model switching circuit and the illumination of lamp adapted, power saving is durable again.
