Abstract
The utility model discloses a screw socket with a pull switch. The utility model is characterized in that a bidirectional thyristor dimmer is fixed in the space between the upper screw socket and the lower casing. Compared with the normal screw socket with a pull switch, a light adjustable knob is arranged on the face and the utility model has the advantages of convenient operation and safety; when various light fittings of the normal screw socket with pull switch match with the utility model, the light fittings can have the function of continuous light adjustment. An LC low pass filter is adopted in the electrocircuit, so the utility model has little interference suppression for transistor radios and is economical and practical.
Description
The utility model is a kind of rib collar lamp socket with pulling switch.
Major part is a desk lamp in the light fixture of existing band stepless dimming, and used dimmer volume ratio is bigger, for dimmer is installed certain requirement must be arranged to the base of desk lamp.This makes the artistic lamp of many exquisitenesses, particularly has design to require or during with material Desk lamp feets such as marble, glass, potteries, is difficult for the installation dimmer, thereby has reduced the use value of these desk lamps.Concerning the simple and easy bedside lamp of some extensive uses, also need light modulation during use, but because complex structure is difficult for realization.Thereby make troubles to people life.
The purpose of this utility model is exactly that a miniature bidirectional triode thyristor dimmer is installed in the space between the upper and lower shell of normal tape pulling switch rib collar lamp socket.Fitting structure and moulding are not being made under the prerequisite of any change, replaced the rib collar lamp socket of original band pulling switch, can realize the purpose of light fixture stepless dimming with the utility model.
The utility model is made up of rib collar lamp socket lower casing, rib collar lamp socket upper casing, bulb adapter screw thread, lamp socket switch assembly, bidirectional triode thyristor dimmer assembly, lamp socket and outside connecting thread, the binding post of power line.Bidirectional triode thyristor dimmer element comprises bidirectional triode thyristor, diac, regulator potentiometer, resistance, electric capacity, inductance.These electric elements are installed on the terminal block, and terminal block is screwed in the upper casing lower end of rib collar lamp socket.A U type breach is arranged, to lay regulator potentiometer on the lower end wall of upper casing.
A hole is arranged on the outer wall of rib collar lamp socket upper casing in addition, draw the backguy part of pulling switch assembly.In the following stomidium of rib collar lamp socket lower casing screw thread is arranged, so that the fixing usefulness of lamp socket, and from then on power line draws.Between the rib collar lamp socket upper and lower shell with being threaded.Circuit has adopted the LC low pass filter.
Advantage of the present utility model only has more a light modulation knob than the rib collar lamp socket of normal tape pulling switch on shell, easy to use, safe and reliable.Replace the rib collar lamp socket of normal tape pulling switch on the various light fixtures with the utility model, can realize stepless dimming.Owing to adopted the LC low pass filter in the circuit, can suppress radio frequency interference, the noise of its generation is met international standards in the 66dB.
Desk lamp ratio that generally can stepless dimming is can not the lamp dimmer price high about about 60% in addition, if after using the utility model, price only increases about 20%.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is outside drawings of the present utility model.
Accompanying drawing 3 is circuit diagrams of the present utility model.
Bulb adapter screw thread 1, lamp socket switch assembly 2, bidirectional triode thyristor dimmer assembly 3, lamp socket and outside connecting thread 4, the binding post 5 of power line, bulb 6, regulator potentiometer 7, the backguy part 8 of pulling switch, rib collar lamp socket upper casing 9, rib collar lamp socket lower casing 10, the aperture 11 of giving vent to anger.
Use the phase shift trigger theory of bidirectional triode thyristor 3CTS and carry out pressure regulation, by R
1, W
1, C
1The rc phase shifter circuit of forming, C is worked as at the admittance angle of decision 3CTS
1Both end voltage is through R
1, W
1When charging back voltage rises to the conducting voltage of 3CTS, the 3CTS conducting that is triggered.3CTS turn-offs voluntarily when alternating voltage zero-crossing.Regulate W
1Can change C during resistance
1Charging interval can change the admittance angle of 3CTS when the alternating current positive-negative half-cycle so that obtain required voltage, make bulb carry out stepless dimming.LC
2Be low pass filter, it can suppress the radio frequency interference of 3CTS.The selection of dimmer electric elements, C
1Can select withstand voltage 63 volts electric capacity for use, for the volume that reduces L can suitably increase C
2Value, regulator potentiometer W
1Selected WH130-1 type carbon composition film potentiometer for use, volume is little, life-span is long, about diameter is 3 centimeters between rib collar lamp socket upper and lower shell, can put into the electric elements of dimmer in the high about 1.5 centimeters space, the bulb less than 40W is carried out stepless dimming, and temperature rise be no more than the regulation of household electrical appliance, if on shell wall under the rib collar lamp socket, open several apertures, also can reduce temperature rise.
Claims (2)
1, a kind of rib collar lamp socket with pulling switch, by rib collar lamp socket lower casing, rib collar lamp socket upper casing, bulb adapter screw thread, the binding post of lamp socket switch assembly, bidirectional triode thyristor dimmer assembly, power line is formed, it is characterized in that bidirectional triode thyristor dimmer assembly is placed in the space between the rib collar lamp socket upper and lower shell, has a U type breach of laying regulator potentiometer near the wall the rib collar lamp socket upper casing lower end.
2, according to the rib collar lamp socket of the described band pulling switch of claim 1, it is characterized in that bidirectional triode thyristor dimmer assembly by terminal block, bidirectional triode thyristor, diac, regulator potentiometer, resistance, electric capacity and inductance are formed.
