Description

Power saving long-life connector of staircase lamp

The utility model relates to a kind of device to the incandescent lamp time delayed turn-off, especially can conveniently be quick installed between lamp holder and the lamp socket, does not need to establish in addition the stair light power-saving life-prolonging connector of circuit and switch.

Prior art is made up of the shell and the interior circuit of insulation.It is characterized in that: civil power advances the rectification full-bridge again through incandescent lamp, the anode of full-bridge output is connected with the silicon controlled anode with the positive pole of rectifier diode, the negative terminal of full-bridge is connected with the silicon controlled negative electrode with the delay capacitor negative terminal, the negative pole of rectifier diode is connected with an end of normal open switch, the normal open switch other end is connected with the positive pole of delay capacitor, the positive pole of delay capacitor is connected with the silicon controlled control utmost point through current-limiting resistance again, start-up circuit is made up of rectifier diode and normal open switch, normal open switch places on the shell, and the shell profile is similar to the common electrical lamp switch.Be to press the startup that normal open switch on the shell is realized circuit by hand when lighting lamp, time-delay is closed circuit for lamp automatically with the bulb outage after a period of time, thereby realizes power-saving life-prolonging.The place that will place hand to touch on this switch when implementing prior art, this switch is diverse with pulling switch, the cassette switch used always now on structure, function.The expense of the taking a lot of work material that just shows when completed construction is implemented prior art is for example wanted rewiring like this, and existing switch is changed in wiring.Since above-mentioned former make it can not be very fast promote to be used.

Document for reference was at 91 years " electronics newspaper " bound volume P ₁₅₀" both-end passive electronic power down switch ".

The purpose of this utility model provides a kind of stair light power-saving life-prolonging connector that is installed between bulb and the lamp socket.It can not only increase the service life to incandescent lamp, saves electricity consumption, and can install quickly and easily, can utilize existing circuit and switch, is convenient to The Application of Technology and popularizes.

Stair light power-saving life-prolonging connector is by constituting with matched shell and the internal circuit of ordinary incandescent lamp, incandescent lamp holder.Shell is made up of two bodies up and down of insulation, is connected by the silk mouth between the last lower body.Two bodies form the little cylinder blanket in two broad in the middle, and shell upper has the power supply contact structures, and shape is divided similar to the metal part of incandescent lamp.The power supply transfer structure is arranged at the bottom, and shape is identical with the lamp socket of incandescent lamp.Support, screw, spring that circuit and permanent circuit are arranged in the intermediate cylindrical cavity.Top with connector during installation snaps in (or screw-in) lamp socket, again incandescent lamp is snapped in the bottom of (or screw-in) connector, circuit is just all connected, and internal circuit is electrically connected and is formed by power contact head, shape of threads lamp socket contact chip, connecting line, start-up circuit, time-delay pass circuit for lamp, circuit board, power supply shell fragment, spring, power contacts, power supply metal screw socket.Start-up circuit is by D, R ₁, R ₂, C ₁, BG, SCR ₁, form, time-delay is closed circuit for lamp by C ₂, R ₃, C ₃, SCR ₂Form, as figure (1).If K is connected, civil power after the D rectification by R ₁, R ₂Power to BG.Rigidly connect when logical at power supply, because C ₁Have a BGU _bCurrent potential is very low, and BG is temporarily ended.BGU _CCurrent potential is very high, SCR ₁The G utmost point because of the trigger voltage conducting is arranged, DL is promptly lighted.Because C ₁Capacity is very little, and its both end voltage is charged to 0.7V very soon, and BG makes U because of getting the positively biased conducting _CVery low, SCR ₁End, start-up circuit is finished the work.Time-delay pass circuit for lamp is started working C ₂On voltage pass through R ₂, SCR ₂G, K extremely slowly discharges, and keeps SCR ₂Conducting, C ₂Because discharge, both end voltage slowly descends, SCR ₂Trigger voltage also descends thereupon, SCR after a period of time ₂Be turned off, DL extinguishes.At this moment K is still in the position of connecting, as long as do not cut off the power supply, this state can be kept down always.When starting for the second time, the K in the circuit must disconnect and connect C in this process of disconnection ₁On voltage to bleed off a part by the be knot by BG.When connecting K again, BG temporarily ends because of can not get positively biased again.SCR subsequently ₁Conducting is to C ₂Charging, SCR ₂Conducting, DL lights, through delaying time automatically with SCR ₂Turn-off, DL extinguishes, and finishes a work period, and K does not need to set up in addition, can directly utilize all kinds of light switches in the completed construction.C ₂Be to be protection SCR ₂Preventing that it from misleading is provided with, and delay time is by C ₂And R ₃Decision, the parameter in this circuit can be delayed time 1 to 2 minute, and entire circuit gross power when static state is 35mW, year power consumption 0.31 degree.

Adopt such scheme, lighting hours reduced to about ten minutes by original one day 3 to 8 hours (decides according to access times).The supply power voltage of incandescent lamp is also reduced to 100V by original 220V.So just, shortened lighting hours, weakened of the infringement of start moment impact electric current, and then prolonged the useful life of bulb, saved many electric power bulb.It can utilize the circuit that has now laid, switch.Do not need from new route, change switch, accomplish to reduce expenses, make the best use of everything.And installation is very simple, and this connector construction is simple, and cost hangs down the simplification of installation process in addition, so very fast the popularizing of this technology come.
