Description

Light-changing and regulating switch for lamp with multi-cap

The utility model relates to a kind of control switch that pendent lamp or other similar ligthing paraphernalia of a plurality of lamp holders compositions are become the light light modulation, need not change former supply line, can realize grouping control to the many lamp holders of light fixture, realize stepless dimming simultaneously, be specially adapted to the control switch of family's many lamp holders pendent lamp.

As everyone knows, the various light fixtures on the market are of a great variety, wherein pendent lamp or the ceiling light of being made up of a plurality of lamp holders greatly, this light fixture of forming by a plurality of lamp holders, light is soft, and outward appearance is luxurious, have very strong ornamentally, this class light fixture has all been installed by a lot of families when decorated house.But in use we find, when this light fixture was loaded onto big wattage bulb, though illumination and decorative effect are fine, power consumption was big, and electricity charge expenditure increases, when weather is hot, and still thermal source that can not be ignored; When this class multi-cap was loaded onto less bulb, rather dark though power consumption is less, work and study all were not suitable for.Though being arranged in the market, a kind of tap changer can realize light modulation to this class light fixture, but because incandescent lamp its luminous efficiency when low voltage power supply can reduce greatly, though at this moment light is dark, but power consumption is still bigger, realize difference switch to the many lamp holders of light fixture, can only change former power circuit, because the concealed wires that adopt in the building, so change circuit difficulty is bigger. more

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of original power circuit of need not changing is provided, but adopts the control of electronic circuit to make the illuminating lamp prodigiosin of a plurality of lamp holders compositions regulate the unit switch of light arbitrarily.

The utility model purpose can reach by following measure: to control a pendent lamp of being made up of 5 lamps is example, sees accompanying drawing 1, and A is in order to substitute the unit switch of former lamp power switch; B is the terminal box that is made of electronic circuit that is installed on the multi-cap, the supply line of a termination light fixture (two lead-in wires) wherein, the other end is divided into two-way output, one tunnel (two lead-in wires) connected the first group that needs normal bright lamp XD1 to form, and another road (two lead-in wires) connects the second group of being made up of lamp XD2-lamp XD5.When the mains switch 1 on the unit switch A disconnected, power supply was cut off, and 5 lamps all do not work, and when mains switch is closed, have only first group lamp bright, press button TA1 or button TA2, can open or close second group lamp, regulated the power of light-control knob W scalable light.

The utility model is realized to multi-cap ornamental and requirements of saving energy by following measure, see accompanying drawing 1, when mains switch K forwards closure to by disconnection, have only lamp XD1 to be lighted in five lamp holders, at this moment light-control knob transfers to light when the brightest, when power consumption at this moment is approximately maximum consumption of power 1/5th, this state can satisfy the requirement of illumination at ordinary times, when work and study or when receiving a visitor, can press button TA1 whole lamps are opened, and adjusting knob W is adjusted to suitable brightness with light, at this moment sufficiency of illumination, light is soft, and is existing very strong ornamental, can satisfy the requirement of various illuminations again.

The realization of the utility model purpose can also describe in detail by the analysis to electrical schematic diagram:

With the pendent lamp be made up of five lamps is example, sees accompanying drawing 2, in the A frame of broken lines is to be connected on former pendent lamp mains switch place in order to substitute the unit switch of former mains switch; It in the B frame of broken lines electronic circuit in the terminal box that is installed on the light fixture; XD1 is in five lamps, is normal bright lamp, and when needing only the mains switch closure, this lamp will be lighted; XD2-XD5 is that other four lamps are the lamp groups that can control separately, can be controlled this group lighting or closing of lamp and not influenced normal bright lamp XD1 by button TA1 and button TA2.

One silicon-controlled voltage regulation circuit is arranged in unit switch, on the power supply branch road of the circuits for triggering of forming by W, C1, C2 and 2CS, be connected to the unidirectional power-supplying circuit of forming by TA1, D1, TA2, D2, be installed at electronic switch on the light fixture by a bistable circuit of being made up of BG1, BG2, its operating voltage is obtained by resistance R 2 dividing potential drops that are series on the lamp holder XD1 circuit.The circuit of control bistable circuit upset is composed as follows: the BG1 collector load resistor be connected to by crystal diode D4 separate by D3, the forward current rectifying and wave filtering circuit that C4 forms, the emitter string of BG2 is by the switching circuit of being made up of BG3, the base stage of BG3 is connected to by D5 by resistance, the negative sense current rectifying and wave filtering circuit that C5 forms.

When mains switch K did not connect, all circuit and power supply disconnected, and all lamp is closed; When mains switch K is closed, power supply is got back to power supply through K switch → bidirectional triode thyristor T1 → lamp holder XD1 → resistance R 2 and is formed the closed-loop path, lamp XD1 is lighted, brightness is by the determining positions of potentiometer W, gets at lamp holder XD1 and powers to control circuit behind rectifying tube D3, D4, D5, D6 rectifying and wave-filtering obtaining a very low dividing potential drop on the resistance R 2 in electric.

By BG1, the bistable circuit that BG2 forms is owing to be designed to asymmetrical form, so entire circuit initial when electric, owing to be separated with rectifier diode between C4, C5, so BG2 always obtains base bias voltage earlier and conducting than BG1, the current collection that makes BG2 is electronegative potential very, BG4 ends, luminous tube one side of photoelectrical coupler because of no current by not triggering controllable silicon T2, so not conducting of T2, the XD2--XD5 lamp all can not lighted.

When pressing button TA1, by TA1, the branch road that D1 forms disconnects, bidirectional triode thyristor can only obtain unidirectional trigger current, thereby can only unidirectional conducting, on divider resistance R2, can only obtain the pulsating voltage of forward, through D3, D4 still can keep the bistable circuit operate as normal of being made up of BG1 and BG2 after the D6 rectification, but owing on divider resistance R2, lost negative half-wave voltage, pass through so rectifier diode D5 no longer includes electric current, electric capacity is very fast through resistance R 4, the discharge of the emitter junction of BG3, make the BG3 base voltage reduce to zero, BG3 is ended, and ending of BG3 will cause the emitter of BG2 to open circuit, and collector potential raises, make the BG4 conducting, photoelectrical coupler O1 obtains electric current, triggers controllable silicon T2 conducting XD2--XD5 is lighted, and luminosity is regulated by the regulating circuit that controllable silicon T1 forms.Because the rising of BG2 collector potential also makes BG1 obtain enough base currents and conducting by R6, the result of BG1 conducting makes the BG1 collector potential descend again, BG2 ends, when button TA1 is released when returning to on-state, because BG1, BG2 has formed new stable state, so lamp holder XD2--XD5 still keeps the state lighted.

When pressing TA2, the branch road that TA2 and D2 form disconnects, controllable silicon T1 can only obtain the negative sense trigger current and unidirectional conducting, on divider resistance R2, has only the negative sense pulsating voltage, after the D5 rectification, keep the BG3 conducting, C4 in the circuit, the very fast discharge off of C5, BG4 transfers to and ending owing to can not get base voltage, controllable silicon T2 is also transferred to by conducting and ending, lamp holder XD2--XD5 is closed, after TA2 discharged, by BG1, the bistable circuit that BG2 forms obtained operating voltage again, as preceding surface analysis, BG2 is owing to obtaining base voltage earlier than BG1, so circuit always is the BG2 conducting when obtaining operating voltage again, the stable state that BG1 ends, thereby keep the pent state of XD2--XD5.

Embodiment of the present utility model: press accompanying drawing 2 and make two circuit boards, be contained in respectively in two plastic casings, mains switch is a ship type switch, TA1, TA2 is the push-button switch with normally-closed contact of diameter 8mm, the home-use pendent lamp formed by 5 40W incandescent lamps of the light fixture that connects, in not changing former floor, under the situation of former power circuit, press accompanying drawing 1 wiring.Result of use: Push switch K, can turn on lamp of XD1 when turning on light, press button TA1 and TA2 and can put or close other four lamps.Can close whole lamp holders of having lighted when pressing mains switch and turning off the light.Under the state of turning on light, to rotate light-control knob and can regulate brightness simultaneously a lamp or five lamps of having been lighted, scope can be transferred to all from normal brightness and extinguish.
