Description

Multi-function energy saving lamp

The utility model relates to a kind of electric lighting device.

Existing electric lighting device, the general electric main that uses, its function or with the light on and off of switch control lighting bulb or fluorescent tube, perhaps except outside the Pass light modulation also is housed mechanism carry out light modulation, storage battery (or dry cell) lamp that uses DC power supply when having a power failure is also arranged, or storage battery (or dry cell) lamp of also subsidiary charging device, it is unassembled but the lighting device of Alternating Current Power Supply and direct current supply generally all separates in one, use control inconvenient, and the volume of the storage battery of subsidiary charging device (or dry cell) lamp is big, cost cost height.

The purpose of this utility model, be to provide a kind of multifunctional energy-saving lamp that Alternating Current Power Supply illumination section and direct current supply illumination and live part are assembled into one, it can be used for exchanging illumination and tunable optical, dc lighting when having the direct-current power supply power failure that to charge voluntarily again, also can charge to external dc power, and make the volume of this lamp little, cheap, Electrical Safety.

The utility model is to realize like this.Referring to Fig. 1, the utility model circuit comprises the dc lighting load, exchanges the double light modulation load of illumination, ac charging power supply display circuit, rectifier diode CZ, filter capacitor C, voltage stabilizing didoe CW and inner DC power supply E, in circuit, have the dpdt double-pole double-throw (DPDT) change over switch K1(that is used to exchange and comprise K1-1 and K1-2 with the DC operation state exchange) and be used to throw light on and the dpdt double-pole double-throw (DPDT) change over switch K2(of work state exchange of charging comprises K2-1 and K2-2), external power supply jack CK1 in circuit, also had.When K switch 1 places " interchange " shelves, K switch 2 places " illumination " when shelves, and single phase alternating current (A.C.) 220V power supply is connected and powered with exchanging the illumination light modulation load of holding concurrently, thereby has realized that interchange throws light on.When K switch 1 places " direct current " shelves, K switch 2 places " illumination " when shelves, and inner DC power supply E also powers with dc lighting load connection, thereby has realized dc lighting.When K switch 1 places " interchange " shelves, when K switch 2 places " charging " shelves, the interchange illumination of alternating current 220V power supply through being together in series held concurrently after light modulation load and the rectifier diode CZ rectification, be parallel with the inside DC power supply E charging of filter capacitor C and voltage stabilizing didoe CW to two ends, exchange the double light modulation load of illumination this moment and played the effect of restriction charging current, simultaneously because the halfwave rectifier effect of rectifier diode, make the voltage that exchanges the double light modulation load two ends of illumination reduce to the direct current half-wave, power only reach power when exchanging illumination 1/4th a little less than, brightness weakens greatly, thereby has also played the effect of light modulation to exchanging the double light modulation load of illumination in charging.The effect of filter capacitor C is that the elimination interchange makes charging current more straight, the effect of voltage stabilizing didoe then makes the voltage of inner DC power supply E charging be stabilized in its specified standards value, when the charging voltage of E surpasses its specified standards value, voltage stabilizing didoe CW begins the reverse breakdown discharge, the E both end voltage reduces, and when dropping to when being lower than the specified standards value, CW stops discharge, so just keep voltage on the battery E in the specified standards value, realized permanent charging.K switch 1 places " interchange " shelves in said circumstances, and when K switch 2 placed " charging " shelves, the 220V AC power was also connected and power supply with the ac charging power supply display circuit, provides the demonstration of ac charging power supply.When K switch 1 places " interchange " shelves, K switch 2 places " charging " shelves, when inserting external power supply among the external power supply jack CK1, inside DC power supply E that is connected in parallel and voltage stabilizing didoe CW break away from disconnection from circuitry, the alternating current 220V power supply double light modulation load of interchange illumination and the rectifier diode CZ through being together in series give external power charging, the two ends that filter capacitor C is attempted by external power supply still strobe, and the external power supply that is recharged can be the direct voltage of any grade in 1 to 48 volt.The same with the situation of giving inner DC power supply E charging, exchange the double light modulation load of illumination and still play the step-down lighting dimming, the 220V AC power is also connected and power supply with the ac charging power supply display circuit simultaneously, provides the demonstration of ac charging power supply.Safety in order to ensure charging, the negative pole of inner DC power supply E must be connected with the center line of alternating current 220V power supply, and the negative pole of external power supply is connected with the center line of alternating current 220V power supply by " charging " shelves of K switch 2 after inserting jack CK1, phase line and center line can not wrongs, like this, could guarantee unlikely charged the hurting sb.'s feelings of the outer casing of power supply negative pole that is recharged.

This multifunctional energy-saving lamp; no matter it is normal or can both guarantee illumination when having a power failure at mains supply; thereby guaranteed that people live normally, working and learning; the Alternating Current Power Supply part fits together with direct current supply and live part; can accomplish that volume is little; use control convenient, the setting of external direct current power supply jack CK1 has solved charge the again problem of usefulness of dry cell and little storage battery.No matter charge to inner DC power supply or to external direct current power supply, the power that exchanges the double light modulation load consumption of illumination has only a little less than 1/4th when the using alternating current 220V, brightness reduces a lot, and just suitable family sees TV or does and not too take the requirements of one's work of eyesight, saved electricity consumption.Charging generally can be arranged in can be carried out during the step-down lighting dimming night in passing, needn't select the time in addition, thereby accomplish that illumination and charging take into account unlikely waste electric energy.The used element of the utility model live part is few, thereby cost is cheap.
