Abstract

A three-gear electric control energy-saving switch is used for carrying out multi-stage control on combined lamps in places such as families, hotels and the like so as to meet the requirements of different illuminations and further save electric energy. The automatic transmission mainly comprises a manual switch , a voltage division device (R1), a rectifying device (D1) and a first gear control device, a second gear control device and a third gear control device. The first gear control is mainly completed by a manual switch , the second gear control device is mainly realized by controlling whether a ground wire (G2) of a second group of lamps is connected with a ground wire (G1) of a first group of lamps through a first relay (J1), and a ground wire (G3) of a third group of lamps is connected with a second ground wire (G2) through a second relay (J2) in a third gear control circuit.

Description

Three step electric control power saving switch

The utility model is the power down switch that is used to control the combination lamp with a plurality of lamps about a kind of.

At present, many families have all installed many with pendent lamp or Assembled lamp, this has played great role to beautifying home environment, but this light fixture power consumption is very big, because the size in room and user's requirement difference only wish that sometimes a lamp or the several lamp in these Assembled lamps is bright, to satisfy different requirements, but common Assembled lamp does not have this function, and it can only have two states promptly complete bright or go out entirely.

The purpose of this utility model will address the above problem exactly, and a kind of third gear electric controlled energy saving switch is provided, and it can carry out the control of three gears to Assembled lamp.

According to third gear electric controlled energy saving switch of the present utility model, it comprises a manual switch (K), divider resistance (R1), rectifying device (D1), it is characterized in that hand switch (K) constitutes first grade of control device; The first filtering voltage regulation device (C1, DW1, D2, C2), first amplifying device (BG1, R2) and first relay (J1) constitute second shift-position control apparatus; The second filtering voltage regulation device (C3, DW2, D3, C4), second amplifying device (BG2, R3) and second relay (J2) constitute the third gear control device; The ground wire of second gear links to each other with the ground wire of first gear by the normally opened contact of first relay (J1); The ground wire of third gear links to each other with the ground wire of second shift-position control apparatus by the normally opened contact of second relay (J2).

Below in conjunction with accompanying drawing a specific embodiment of the present utility model is elaborated.

Fig. 1 is the physical circuit figure of the utility model third gear electric controlled energy saving switch.

In Fig. 1, L1, L2, L3 is respectively first group in the Assembled lamp, second group, the 3rd group of lamp, they can be one or more lamps, it can be incandescent lamp, the lamp of fluorescent lamp or other type, resistance R 1 plays the dividing potential drop effect, diode D1 plays the halfwave rectifier effect, capacitor C 1, C3 strobes, voltage stabilizing didoe D1, DW2 plays pressure stabilization function, capacitor C 2, C4 is two charge and discharge capacitances, triode BG1, BG2 plays the relay coil control action, resistance R 2, R3 is respectively triode BG1, the base biasing resistor of BG2, relay J 1, J2 is respectively applied for second group of lamp L2 of control, the ground wire of the 3rd group of lamp L3 is switched on or switched off.

The operation principle of the utility model third gear electric controlled energy saving switch is as follows:

F ' connects power firestreak, and the G1 point connects power ground, and power supply can be common 220V alternating current.Power firestreak can adopt special fuse through K switch (such as being a pulling switch) and protector BX(, promptly works as the big disconnection of electric current, the little connection of electric current) receive the F point.First group of lamp L1 is attempted by between F point or the G1 point, and second group of lamp L2 is attempted by between F point and the G2, and the 3rd group of lamp is attempted by between F point and the G3.When K switch was connected, first group of lamp L1 can be bright, and this just constitutes first grade of control of this switch.The power-half cycle is by the R1 dividing potential drop, and the D1 rectification is charged to C1, also charges to C2 through D2 in addition, and after K switch was connected several seconds, capacitor C 1 and C2 were full of the rated value that electricity, voltage reach DW1.This moment is because the intermediate contact of relay J 1 connects the G1 point, normally-closed contact connects the base stage of triode BG1, normally opened contact connects the G2 point, triode BG1 base potential is than emitter current potential height, so not conducting of triode BG1, relay J 1 coil does not have operating current, relay is failure to actuate, second group of lamp L2 ground wire G2 is obstructed, therefore can not be bright, so the ground wire G3 of the 3rd group of lamp L3 also derive from G2 the 3rd category L3 can not be bright.At this moment, if disconnect K, on the triode BG1 base stage there be not original high potential, the BG1 conducting, keep down in capacitor C 2, C1 discharge, relay J 1 action, the intermediate contact of J1 is swung to normally-closed contact, and G2 and G1 connect, connect K again this moment, and then not only L1 is bright, and second group of lamp L2 is also bright at once.This has just constituted second grade of control of this switch.On the bright basis of second group of lamp, cross several seconds (1-3) and disconnects again, connect K switch, then identical with above-mentioned second gear control, the 3rd group of lamp L3 is also bright, finishes the third gear of this switch and controls.Want from 3 groups of lamps complete brightly to bright first group of L1 only, a little longerly just can realize as long as will disconnect the time of K.

Above specific embodiment of the utility model is described in detail, it can be divided into three groups with illuminating lamp on demand under the two-wire system situation that does not change original switch control, by the control of this switch, can realize different lights, is specially adapted to family, the hotel.Whole circuit among Fig. 1 is contained in the Assembled lamp, also dotted line left-hand component can be made parts, can transform existing various Assembled lamps with these parts.With the pulling switch closure, first group is bright, reaches power saving during use, as increasing brightness, Drawing switch again after three seconds please, promptly second group lamp is bright, draws for the third time all lamps all to open, and all turns off the light for the 4th time, repeats thus, note three second electric process.
