Abstract
The utility model discloses an energy-saving and light-regulation pulling switch, which is in particular suitable for the switching and adjustment of illuminating lamps whose power is under 100W. The utility model is composed of a bidirectional thyristor, a bidirectional trigger diode, resistors, capacitors and a switch; The utility model can make the bidirectional thyristor obtain different angles of flow because of the adoption of resistor and capacitor phase shifting to achieve the purpose of light-regulation, any value under the rated power can be obtained, and namely, the brightness can be adjusted according to needs. The utility model has the advantages of energy conservation and convenient use, and besides, the switch can be switched on at zero bit or at the minimum power, which limits the influences of the surge current on the bulbs and other elements and extends the service life of the bulbs and the other elements.
Description
The utility model relates to backguy dimming energy-saving switch, is specially adapted to switch and adjusting to the following lighting bulb of 100W.
Application number is 85205736 the change light pulling switch of lengthening the life, disclosing portion in the patent document lengthens the life and becomes light pulling switch technology, the utility model is to increase by a general-purpose diode to realize by half bright to complete bright change light effect in existing switch, realize becoming light because of it utilizes diode, can not reach the requirement of stepless change light.
The purpose of this utility model provides the backguy dimming energy-saving switch of the stepless change light of a kind of energy.
The utility model is to be made of bidirectional triode thyristor, bidirectional trigger diode and resistance, electric capacity, switch.
Below in conjunction with embodiment and accompanying drawing the utility model is described:
Accompanying drawing 1 is circuit theory diagrams of the present utility model;
Accompanying drawing 2 is a rotating disk cutaway view of the present utility model;
See Fig. 1, resistance R
1, capacitor C
1And resistance R
2, capacitor C
2Respectively be a joint phase-shift network, maximum phase shift 90 degree of every joint.But two joint phase-shift networks are phase shift 180 degree altogether, adjust potentiometer resistance R
1Size, can make bidirectional triode thyristor obtain the angle of flow vary in size, thereby the brightness of electric light is changed.
Embodiment:
At first resistance R
1, R
2With capacitor C
1, C
2The ties of the two joint phase-shift circuits that constitute are printed on the circuit board, again a termination of bidirectional trigger diode (or two diode reverse parallel connection after) are gone into resistance R
2, capacitor C
2The connection place, its another termination The Trigger of Bidirectional Triode Thyristor utmost point, the in addition two ends of bidirectional triode thyristor are connecting resistance R respectively
1With capacitor C
2An end, an end of the circuit after the connection connects power supply by bulb and plug, the other end connects power supply by switch and plug.
Switch of the present utility model is identical with the structure of existing pulling switch, has only changed the version of rotating disk, and it is made up of a rotating disk, rope, two metal columns and shell fragment, and metal column is installed on the circuit board that prints, and rotating disk is installed on the potentiometer footstalk.See Fig. 2, rotating disk upper and lower two-layer be radius R ' circle, half is the circle of radius R for the intermediate layer, second half is the ellipse of major axis R ', and also be equipped with a rope on the intermediate layer, drop out the arc-like sheet that corresponding with rotating disk (promptly being about R ') also is housed at the disk edge place for preventing rope.One end of shell fragment is fixed on the metal column.Shell fragment just in time is in the interposition place of rotating disk.The pulling rope, dial rotation, when ellipse partly forwarded on the shell fragment, the shell fragment other end is the contacting metal post not, at this moment deenergization.When rotating disk during in other position, the other end of shell fragment touches mutually with metal column.At this moment, the pulling rope changes resistance, and two metal columns are plug and resistance R respectively

The utility model also shouldn't capacitor C
2And constitute, also can add heat abstractor on the bidirectional triode thyristor of the present utility model.
The utility model makes bidirectional triode thyristor obtain the different angles of flow owing to adopt resistance, electric capacity phase shift, reaches the purpose that makes bulb become light, can obtain the following arbitrary value of rated power, i.e. brightness can be by regulating.Has energy-conservation, advantage easily; Simultaneously switch is started when zero-bit or minimum power, limited impulse current to the influence of bulb and other element, prolonged useful life.
