Description

New and effective economize on electricity makes things convenient for lamp

One, technical field

The utility model relates to a kind of illuminating new and effective economize on electricity and makes things convenient for lamp.

Two, background technology

Light fixture is that people work, the equipment that must use in the studying and living, but when power failure suddenly or when non-Electric region is worked, people have to adopt various measures, to solve lighting problem, as: use power-cut emergency lighting lamp (replacement candle), no civil power and field work illuminating lamp, individual's reading and writing lamp, flashlight and signal lamp or the like, but because this type of light fixture reserve of electricity is limited, effective storage life is short, can not satisfy the needs of long-time illumination, and energy resource consumption is big, the expense height, therefore, sometimes people have to take other illumination articles for use, as: various fuel-burning lamps, candle etc., and use these articles for use illumination lights not enough, and dangerous, bother again, even just can not use in some place, at all as open-air wind and rain sky, work night in the open, can't light at wind and rain intermediate fuel oil lamp and candle at all, so, does the illumination that how to solve in particular cases need?

Three, utility model content

At above-mentioned situation, the purpose of the utility model just provides a kind of energy-efficient lamp that makes things convenient for, can effectively solve illuminating energy-saving and need problem especially, the technical scheme of its solution is at the housing built-in control circuit, there is snoot the housing front portion, there is bonnet at the rear portion, in the anterior diffuser of housing illuminating part is arranged, housing has switch on the side, said control circuit is through switch connecting resistance and transformer by DC power supply (battery), connect two triodes respectively through resistance again, one connects base stage, one connects collector electrode, the collector electrode of the triode that joins with primary coil connects two electric capacity through diode, the electric capacity and the secondary coil that are cascaded are arranged between the base stage of this triode and emitter, the emitter of two triodes links to each other, connect the resistance that links with emitter and the negative pole of light-emitting diode (being lighting bulb) on the base stage of the triode that joins with secondary coil, transformer is through rectifier diode sending and receiving optical diode (being lighting bulb) positive pole, it is simple in structure for the utility model, novel unique, easily produce, easily dress usefulness can be widely used in the power-cut emergency lighting lamp, no civil power or field work illuminating lamp, individual's reading and writing lamp, flashlight and signal lamp or the like light fixture; If cooperate solar cell and chargeable battery, can form independent lighting system and navigation light etc., very easy to use, application surface is very wide, energy saving both had been convenient for people to work, studying and living, alleviated national power shortage again, reduce expenses, it is applied, and benefits the nation and the people.

Four, description of drawings

Fig. 1 is an external structure of the present utility model.

Fig. 2 is a control circuit structure chart of the present utility model.

Five, embodiment

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

Provided by Fig. 1, Fig. 2, the utility model is that the control circuit by housing and interior dress thereof constitutes, and there is bonnet 2 at housing 1 rear portion, there is snoot 4 front portion, illuminating part 5 is housed in the snoot 4, and housing has switch 3 on 1 side, and said control circuit is that battery E is through K switch connecting resistance R ₁One end and transformer L ₁, L ₂The centre cap that links to each other, resistance R ₁Another termination triode BG ₁Base stage and triode BG ₂Collector electrode, triode BG ₁Base stage through capacitor C ₁Meet the secondary coil L of transformer ₃, secondary coil L ₃The other end with triode BG ₁Emitter and triode BG ₂Emitter link triode BG ₁Collector electrode meet transformer L ₁, triode BG ₂The negative pole (bulb) of base stage sending and receiving optical diode LED, and through resistance R ₂Meet triode BG ₂Emitter and capacitor C in parallel ₂And capacitor C ₃, triode BG ₁Collector electrode through diode D ₃Connect capacitor C in parallel ₂, capacitor C ₃With rectifier diode D ₁Negative pole and the positive pole of LED, transformer L ₂Meet rectifier diode D ₁Positive pole and diode D ₂Negative pole, K switch places outside housing 1 side, battery E places in the housing 1 on bonnet 2 tops.Illuminating part 5 promptly is the LED among Fig. 2 among Fig. 1, and switch 3 is the K switch of Fig. 2.

Working condition of the present utility model is by triode BG ₁, resistance R ₁, capacitor C ₁And transformer coil L ₁, L ₂, L ₃The oscillation step-up circuit of forming becomes the direct current of 1.5～3V into the higher alternating current of voltage, again through diode D ₁Rectification, capacitor C ₂, capacitor C ₃Filtering becomes the direct current that suitable LED (bulb) is worked, diode D ₂, D ₃Be fly-wheel diode, can improve the conversion efficiency of circuit, LED converts electrical energy into luminous energy expeditiously, by triode BG ₂And resistance R ₂The current-limiting circuit of forming light-emitting diode (bulb), when electric current reaches set point, triode BG ₂Conducting makes triode BG ₁ON time shortens, and prolong deadline, and the operating current of light-emitting diode (bulb) is limited in certain limit, brightness stability, the life-span prolongs, efficient electricity-saving, can throw light on for a long time, effectively overcome the problem that the lighting apparatus effective time is short, energy consumption is big of existing DC power supply.
