Embodiment 1

A kind of single stay dimmer switch, as shown in Figure 2, fixed resistance R1, the R2 of three series connection, R3 constitute variable resistor, and totally three groups, resistance is respectively R _A=0, R _B=R1, R _C=R1+R2, R _D=R1+R2+R3.Ratchet 5 has four strokes, and relatively dimmer board 1 has four axial symmetry to be respectively the conduction region at 90 ° of angles with it, be followed successively by the pass, secretly bright, in bright, light, and respectively with RD, R _C, R _B, R _ABe connected.On the metal slip ring 3 that fixes with ratchet shaft 2, also has a contact spring 4, contact spring 4 is along with the rotation of ratchet 5 contacts with the different conductive regions of dimmer board 1, conducting strip A6 one termination is gone into light adjusting circuit, the other end is that free end contacts with slip ring 3, during use, and the pulling backguy, contact spring 4 contacts with the different conduction regions of dimmer board 1 under ratchet 5 drives, respectively with R _D, R _C, R _B, R _AInsert light adjusting circuit, realize the function of voltage-control dimming.

Embodiment 2

Two backguy dimmer switchs as shown in Figure 3, two series resistance R1, R2 constitute totally two groups of variable resistors, resistance is respectively R _B=R1, R _C=R2+R1.Two pulling switch I, II such as Fig. 3 (a) are housed in the terminal box, and II is a common pulling switch K2, with R _SInsert light adjusting circuit.The dimmer board 1 of switch I has 4 conduction regions such as Fig. 3 (b), is respectively the district of turning off the light, 60 ° of angles, the clear zone in district, the hexagonal angle of turning off the light, 60 ° of angles, clear zone in the hexagonal angle, and middle clear zone communicates, and and R _BBe connected.The ratchet 5 of switch I has six strokes, with fix a short circuit sheet 9 on 60 ° of corresponding ratchets of angle behind the middle clear zone, 9 of short circuit sheets cover the preceding part of ratchet, have two conducting strip B7, C8 stiff end directly and terminals join, the free end realization is spacing to ratchet 5, and constitutes K switch 1 jointly with short circuit sheet 9.The light modulation process is as follows:

1, when selecting the half-light illumination, the strain plate II of leaving behind, K switch 2 closed paths charge to capacitor C by R1, R2, and diac D provides pulse, and the bidirectional triode thyristor 3CTS control utmost point is touched and can send out and conducting, bulb gets electric lighting, backguy II again, K2 disconnects, phase-shift voltage regulating loop dead electricity, bidirectional triode thyristor 3CTS closes, the bulb outage.

2, when selecting the intermediate light illumination, pulling strain plate I, ratchet 5 drives slip ring 3, make contact spring 4 rotate 60 °, contact spring 4 contacts also rest on clear zone in the dimmer board 1, and this moment, R2 is cut, electric current is by R1, middle clear zone, contact spring 4, slip ring 3, conducting strip A6 charges to capacitor C, and diac D exports pulse, bidirectional triode thyristor 3C7S is triggered and conducting, gets electric lighting.

During 3, as the illumination of selection high-high brightness, spur the backguy I again, ratchet 5 drives slip ring 3 again, and contact spring 4 rotates 60 °, and contact spring 4 contacts the also left alone without help clear zone in the dimmer board 1 of staying.At this moment, short circuit sheet 9 will make conducting strip B7, C8 short circuit, i.e. K1 closure, and the result makes all dimming electronic elements by short circuit, and makes its stop work.When turning off the light, spur the backguy I again, K1 at first disconnects, this moment, bulb was by the brightest intermediate light that drops to, and this is because K1 is when disconnecting, clear zone during contact spring does not also break away from, so just obtained the chance that step-down is turned off the light, when contact spring enters when district of turning off the light, the electric light outage is extinguished.

The utility model has following advantage:

(1) light modulation protection eyes: see TV night, night, the infant woke up suddenly, breast-feeded, changing babies' napkin more, but the ideal selection half-light, was subjected to high light in avoiding having drowsy eyes and stimulates, and is helpful to protection infant eyes;

(2) the light modulation step-down prolongs bulb service life: the reason of the incandescent lamp bulb disintegration of filament, the overwhelming majority are that the generation switching overvoltage causes because in the moment of full voltage switching electric light. And this switch is to reduce under the voltage condition, opens and closes electric light, can the production operation overvoltage, thereby prolonged service life of bulb.

(3) electricity-saving dimming: take the 100W bulb as example, when the bulb of 60W was selected intermediate light, the dimmer voltage of bulb was 110 volts, and the power that bulb consumes is 15W; When the bulb of 100W was selected half-light brightness, the dimmer voltage of bulb was 40V, and the power that bulb consumes is 3.3W.

The family of a 2 bedrooms, if throw light on the bulb of two 60W, throw light on one hour with intermediate light every day, 0.07 degree that can economize on electricity every day, every month 2.7 degree that can economize on electricity, 1 year 30 degree that can economize on electricity. If with the illumination of the bulb of two 100W, every day is with half-light illumination one hour, 0.19 degree that can economize on electricity every day, and every month 5.8 degree that can economize on electricity, 1 year 10 degree that can economize on electricity, this is the astronomy economize on electricity numeral that can't add up for the whole nation, benefits the nation and the people, economic benefit is very grand.
