Embodiment Construction

[0010] Such as Figure 1-2 As shown: a portable power-free luminous lamp of the present invention includes a casing, a sleeve is fixed inside the casing, and a permanent magnet block that can move relatively along the sleeve is arranged in the inner cavity of the sleeve. The permanent magnet block The two ends of the sleeve can be connected to the front and rear ends of the sleeve through a spring respectively. On the outer wall of a part of the sleeve, a section of coil is wound, and a charging and lighting circuit is connected between the terminals at both ends of the coil. The light-emitting element in the circuit fixed on the shell. In the charging and lighting circuit, a diode D1 and a light-emitting element D2 are sequentially connected in series between the two terminals of the coil, a capacitor C is connected in parallel with the light-emitting element D2, and a capacitor C is connected in series at the end of the light-emitting element D2. A switch K, the light-emitt...

Abstract

The invention relates to a convenient and fast power-supply-free luminescent lamp which comprises an outer casing. A sleeve cylinder is fixed in the outer casing, a permanent magnet block capable of relatively moving along the sleeve cylinder is arranged in a cavity of the sleeve cylinder, two ends of the permanent magnet block can be connected with the front end and the back end of the sleeve cylinder through a spring respectively, a section of the coil is wound on the outer wall of partial sleeve cylinder, a charging and lighting circuit is connected between wire connectors at two ends of the coil, and a lighting element in the circuit is fixed on the outer casing. The convenient and fast power-supply-free luminescent lamp has the advantages of being compact in structure, convenient to carry and capable of providing power for the charging and lighting circuit along movement of users for lighting or charging, and removes troubles for changing a battery or charging at regular intervals.

Description

technical field [0001] The invention relates to a portable power-free light emitting lamp. Background technique [0002] Existing portable lamps, such as flashlights, require frequent battery replacement or charging, which is cumbersome to use, and waste batteries will cause permanent pollution to the environment. In addition, they are large in size and not easy to carry. Contents of the invention [0003] The purpose of the present invention is to provide a portable power-free luminous lamp that can provide small-scale lighting at any time without an external power supply. [0004] The purpose of the present invention is to realize through the following technical solutions: [0005] A portable power-free luminous lamp of the present invention includes a casing, a sleeve is fixed inside the casing, and a permanent magnet block that can move relatively along the sleeve is arranged in the inner cavity of the sleeve, and the two ends of the permanent magnet block are It can...
