Abstract
The utility model discloses a single wire bridge type light-regulating switch, belonging to an electric switch capable of regulating a light, and composed of a bridge type power supply switch and a light-regulating system which are mutually independent. When a bridge type key is respectively pressed toward the both sides of the switch, a circuit is positioned at the on-and-off state. An auxiliary phase shift circuit is provided between the trigger and the phase shift circuit of the light-regulating system, and the auxiliary phase shift circuit can increase the phase shift angle and enlarge the conducting angle of the current so as to expand the using range of the light-regulating switch. After the utility model is communicated with a power supply, the light-regulating switch changes the resistance value of the potentiometer through regulating a rotating wheel on a panel and achieves the light-regulating purpose so as to shorten the lamp turning-on and turning-off time, having convenient operation and long service life.
Description
The utility model belongs to the electric switch of tunable optical.
The electric switch of existing tunable optical is made up of mains switch and light adjusting system, and mains switch generally adopts carbon-film potentiometer, and light adjusting system then comprises trigger and phase-shift circuit.Its trigger is made up of bidirectional triode thyristor and bidirectional diode, and phase-shift circuit comprises potentiometer W and a capacitor C, and the two ends of above-mentioned carbon-film potentiometer switch link to each other with light adjusting system.Be mutually related in this tunable optical electric switch mains switch and light adjusting system controlled by the footstalk of potentiometer W all, thereby, in the process of turning on light at every turn and turn off the light, the slip arbor contact of potentiometer W will with the carbon film wearing and tearing of W once.If things go on like this, cause potentiometer W poor contact of contacts easily, reduce its reliability and useful life.Secondly after turning on light, all need regulate the brightness of a bulb, this in use makes troubles for the user at every turn.The 3rd; because its phase-shift circuit is made up of potentiometer W and capacitor C; when the W resistance is very big; the charging voltage of C rises very slow, and its resistance may make the charging voltage of C not reach The Trigger of Bidirectional Triode Thyristor voltage in the power supply half period during greater than a certain numerical value; that is to say; can only control to a certain minimum brightness to bulb brightness, desire low again, then uncontrollable.Be pointed out that at last, above-mentioned light modulation electric switch, at the closed initial stage of power supply, bulb side voltage can only present very low value, so it is applicable to incandescent lamp, and is not suitable for fluorescent lamp, because fluorescent lamp is a gas discharge type, its starter needs certain high voltage.
The purpose of this utility model is design a kind of reliability height, long service life, applied range, dimmer switch with low cost, easy to use, makes it not only to be suitable for the light modulation needs of luxurious light fixture, also can be used for various types of light fixtures.
The utility model adopts separate mains switch and light adjusting system.This mains switch is made up of bridge-type button, support, groove, movable contact flat, guide card, spring, above-mentioned bridge-type button is in the face of the one side of groove, being positioned at the middle part has a tapped screw, and its flight pitch equates that with above-mentioned spring base this spring is along being threaded in the spring eye.Around screw, be distributed with four V-shaped grooves.Above-mentioned support has two sides staggered relatively.Is empty in the middle of the side, a pinnacle is respectively arranged on it, when the bridge-type button was placed on this support in the groove, inserted respectively in two relative V-shaped grooves in above-mentioned four V-shaped grooves on two pinnacles of this on the support.One end of above-mentioned movable contact flat is a U-shaped, also respectively there is a pinnacle on its both sides, and its recessed position has a circular hole, when the U-shaped end of movable contact flat is aimed at spring in the above-mentioned screw, two other V-shaped groove around the screw is put on the pinnacle on U-shaped end both sides respectively, at this moment, the circular hole at the recessed position of movable contact flat U-shaped end is connected with spring end.Like this, this support in bridge-type button and the groove cooperates for movable.In addition, respectively there is a boss both sides of groove, and when pressed both sides, its two ends were placed on respectively on two boss with the bridge-type button, and it is moving to cause the movable contact flat of plumbness also to be swung sideward respectively, and with the guide card contact of groove one side or separate.Above-mentioned light adjusting system also is connected to auxiliary phase-shift circuit therebetween except that trigger and phase-shift circuit, it comprises two resistance R
