Abstract
The utility model relates to a life use article, in particular to a desk lamp, which comprises a power generator and a desk lamp body, wherein the power generator is provided with a base, and the desk lamp body is provided with a light emitting diode. The desk lamp is characterized in that the desk lamp body is connected with a case of the power generator, a crank is arranged on the power generator, the interior of the power generator is connected with an electrical storage device, the electrical storage device comprises a supercapacitor and a voltage regulator diode, and the light emitting diode, the supercapacitor and the voltage regulator diode are connected in parallel. Under the condition of rotating the crank by hand, the electricity of the light emitting diode is directly supplied by a direct current power generator, simultaneously, the supercapacitor is charged, and the current is provided for the light emitting diode by the supercapacitor under the condition of stopping rotating the crank by hand. The desk lamp has the beneficial effects that the desk lamp can be used while charging, the use is convenient, the energy is saved, the environment is protected, the operation and the structure are simple, the design is reasonable, and the application range is wide.
Description
Technical field
The utility model relates to a kind of daily necessities, specifically is a kind of desk lamp.
Background technology
At present the desk lamp great majority that use are directly to receive to use on the power supply of 220v or the charging desk lamp of battery formula, just can not directly use or charge to desk lamp if run under the situation of power failure, desk lamp service life of battery formula is short in addition, charging times is limited.
Summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, provide a kind of promptly fill promptly with, under the situation that is not having electricity also operable desk lamp.
The utility model comprises the generator that has base and has the desk lamp body of light emitting diode, its special character is: described desk lamp body is connected with the shell of generator, generator is provided with crank, the inside of generator is connected with electrical storage device, electrical storage device comprises super capacitor and Zener diode, is connected in parallel between light emitting diode, super capacitor and the Zener diode three.Under the situation of hand crank, light emitting diode is directly by the dc generator power supply, and to the super capacitor charging, the situation of handle is next to provide electric current by super capacitor to light emitting diode if stop simultaneously.
Described generator is a dc generator.The direct current that dc generator sends can use to the super capacitor charging.
Described light emitting diode is one group connects in twos, structure in parallel again after 5 series connection in twos.Concrete quantity can design according to the total voltage that circuit provides.
The beneficial effect of desk lamp of the present utility model: promptly fill i.e. usefulness, easy to use, energy-conserving and environment-protective, operation, simple in structure, reasonable in design, applicable situation is wide.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model circuit theory diagrams;
Among the figure: 1, base, 2, generator, 3, crank, 4, the desk lamp body, 5, light emitting diode, 6, super capacitor, 7, Zener diode.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Accompanying drawing is a kind of specific embodiment of the present utility model, and this embodiment comprises generator 2 that has base 1 and the desk lamp body 4 that has light emitting diode 5, and it is characterized in that: described desk lamp body 4 is connected with the shell of generator 2, and generator 2 is a dc generator., generator 2 is provided with crank 3, and the inside of generator 2 is connected with electrical storage device, and electrical storage device comprises super capacitor 6 and Zener diode 7, is connected in parallel between light emitting diode 5, super capacitor 6 and Zener diode 7 threes.
The utility model in use, shifting to an earlier date hand crank 3 allows the direct current generator generating supply with the super capacitor charging, electric capacity just can use directly for light emitting diode 5 powered lightings after having dashed electricity, can not charge to electric capacity when running under the situation that does not have electricity, at this moment this desk lamp just can have been given full play to the advantage of himself.Dc source is a dc generator 2, manually shake generator 2 and can produce direct current, the direct current that the utility model needs is 6V, and 360mA, light emitting diode 5 are one group and connect in twos, 5 compose in parallel again after the series connection in twos, the operating voltage of single diode is 3v, and blanking voltage is 2v, and operating current is 30mA, the voltage of total load is 4v-6v like this, and electric current is 300mA.Calculate the capacity of super capacitor thus, formula is arranged
V
2And V
1Be respectively the operating voltage and the blanking voltage of load, I is an operating current, and T is the working time, if T=1200s brings formula into and can get C=180F.The model of the super voltage that the utility model adopted is SCPC6R5227, and promptly rated voltage is 6.5V, and capacity is 220F, and the working inverse voltage of Zener diode 7 is 6V, and promptly the ceiling voltage of output (load end) is 6V.
