Abstract

The utility model relates to a lamp, particularly a portable non-power-supply luminescent lamp, which comprises a casing, wherein, a sleeve is fixed in the casing; a permanent magnet block which can relatively move along the sleeve is arranged in the cavity of the sleeve; the two ends of the permanent magnet block can respectively be connected with the front and back ends of the sleeve by a spring; a section of a coil is wound on the outer wall of a portion of the sleeve; a charging and lighting circuit is connected with the portion positioned between the binding heads of the two ends of the coil; a light-emitting element in the circuit is fixed on the casing. The utility model has the advantages of compact structure, portability and no need of an additional power supply, and omits troubles of periodically changing a battery or charging the battery.

Description

Portable power-free electroluminescent lamp

Technical field

The utility model relates to a kind of light fixture, particularly a kind of portable power-free electroluminescent lamp.

Background technology

Existing portable lamp as flashlight etc., needs in the use often to change battery or charging, uses trouble, and old and useless battery can cause permanent pollution to environment, and its volume is bigger in addition, also is not easy to carry.

Summary of the invention

Technical problem to be solved in the utility model provides and a kind ofly can need not additional power source, the portable power-free electroluminescent lamp that can provide illumination among a small circle to use at any time.

Portable power-free electroluminescent lamp of the present utility model includes a shell, be fixed with a sleeve in the enclosure, a permanent magnets that can relatively move along sleeve is arranged in barrel bore, the two ends of permanent magnets can be connected the sleeve rear and front end by a spring respectively, on the outer wall of a part of sleeve, be wound with one section coil, be connected with a charging and lighting circuit between the connector lug at the two ends of coil, the light-emitting component in the circuit is fixed on the shell.There are a diode D1 and a light-emitting component D2 to be connected on successively between two connector lugs of above-mentioned coil in described charging and the lighting circuit, also have a capacitor C in parallel with light-emitting component D2, also be serially connected with a K switch at light-emitting component D2 one end, described light-emitting component can adopt light emitting diode, bulb or other element.

The utility model compact conformation, be easy to carry, and can provide electric energy for charging and lighting circuit along with user's motion, luminous or charging for it, thereby saved the trouble of periodic replacement battery or charging.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the circuit diagram of charging of the present utility model and lighting circuit.

The specific embodiment

As shown in Figure 1, be fixed with a sleeve 2 in the shell 1 of this portable power-free electroluminescent lamp, a permanent magnets 3 that can relatively move along sleeve is arranged in barrel bore, the two ends of permanent magnets can be connected the sleeve rear and front end by a spring 4 respectively, on the outer wall of a part of sleeve, be wound with one section coil 5, coil two connector lugs between be connected with one the charging and lighting circuit 6, the light-emitting component in the circuit is fixed on the shell.

As shown in Figure 2, there are a diode D1 and a light-emitting component D2 to be connected on successively between two connector lugs of above-mentioned coil in charging and the lighting circuit, also have a capacitor C in parallel with light-emitting component D2, also be serially connected with a K switch at light-emitting component D2 one end, light-emitting component D2 is a light emitting diode.

The utility model in use, along with user's motion, permanent magnets is slided before and after in sleeve, in coil, generate electric current, make light-emitting component luminous, if this moment, K switch was in off-state, use later on for light-emitting component then to capacitor C charging, and with electrical power storage.
