Abstract

The utility model discloses an incandescent lamp holder with protection function. The utility model is characterized in that a diode and a capacitor are arranged in an ordinary lamp holder. The utility model has the advantages that the service life of a bulb can be prolonged for 11 times; the energy-saving effect is good; the electric network can benefit; the utility model is suitable for places which need only continuous illumination instead of strong illumination.

Description

Incandescent lamp holder with protection function

This reality is made novel civil electric appliance class, the particularly Incandescence lamp holder of relating to.

No matter at present Incandescence lamp holder is screw thread mouth or socket lamp holder, have can consolidate at the bottom of the plane on the wall and with the line end of falling to nib, all be two power contact structures, inner all not to any device of voltage-regulation and Current Regulation; And the protector for household electrical appliances of selling separately on the market, function concentrates on outage, earth leakage protective, overvoltage, under-voltage protection mostly, does not also have electricity-saving function; Though a kind of device that is called the optoacoustic cut-off switch is arranged on the market, for only needing Chang Ming not need the place of high brightness incompatible again.

At the shortcoming of the said goods, the object of the present invention is to provide a kind of Incandescence lamp holder with step-down and rectified action, make existing incandescent lamp can improve ten times life-span, and play energy-conservation effect.

The utility model utilizes the unidirectional conducting principle of diode, half is surplus to make civilian alternating current step-down, utilize the capacitor filtering principle again, make the electric current after the step-down more steady relatively, thereby incandescent lamp is worked under half state of rated voltage, since in low-voltage with work under the voltage more stably, thus can improve greatly the useful life of incandescent lamp, and reach purpose of energy saving.

The technical solution of the utility model is: withstand voltage diode (2) that is not less than 360V of serial connection on a contact of existing Incandescence lamp holder and lamp holder external power supply; the withstand voltage 360V of being not less than, a capacity in parallel are not less than the electrolytic capacitor (1) of 2.2 microfarads between two contacts of external power supply, and constitute an Incandescence lamp holder that defencive function is arranged.

The utility model advantage is, can play life-saving to incandescent lamp, makes the effect that plays four times of economize on electricitys with the bulb of power, and the induction reactance of general electrical network there is certain compensating action, this device only increases few element on the basis of existing lamp holder, make simple, easy to use.

Accompanying drawing 2 the utility model circuit theory diagrams

Below in conjunction with embodiment the utility model is described further:

For present commercially available ordinary incandescent lamp lamp holder, with a contact of external connection and connect between the contact of lamp and disconnect, connect with diode (V is more than or equal to 360); Withstand voltage in parallel is not less than 360V between external two contacts, and capacitance is not less than the electrochemical capacitor of 2.2 microfarads, constitutes the Incandescence lamp holder with defencive function.

Claims

1, a kind of Incandescence lamp holder that defencive function is arranged; but it is by the attaching light bulb socket; two electric contacts that contact with bulb; two electric contacts that contact with power supply and shell are formed; be serially connected with a diode on the contact that it is characterized in that contacting, capacitor in parallel between two contacts that contact with power supply with power supply.

2, according to right 1 described a kind of Incandescence lamp holder that defencive function is arranged, it is characterized in that: the minimum 360V of being of the withstand voltage of diode, the minimum withstand voltage of capacitor is 360V, the capacitance minimum is 2.2 emblem methods.
