A wire and a stripping method thereof, and a light strip are provided. The stripping method includes the following steps: holding a wire by a holder, the wire including an insulation layer and a conductor covered by the insulation layer; mounting the holder on a worktable of a an optical device; and activating a light emitter of the optical device to emit a light beam irradiating onto the insulation layer to ablate a portion of the insulation layer to form at least one through hole that penetrates the insulation layer to expose a portion of the conductor.

The subject matter of the invention is a manual multispool cabinet for winding a number of filaments (40, 40a) onto a respective removable transport spool (14, 14a) having a driven main winding shaft (10, 10a) per transport spool (14, 14a), wherein the main winding shaft (10, 10a) is formed for an exactly fitting reception of the transport spool (14, 14a, 214), and wherein the main winding shaft (10, 10a) drives the transport spool (14, 14a). Providing such a manual multispool cabinet that has such an increased filament speed is achieved in that, in addition to the transport spool (14, 14a), a buffer spool (12, 12a) is held on the main winding shaft (10, 10a).

A power supply device is provided, which includes a plurality of battery packs and a plurality of unidirectional conductive elements. The plurality of battery packs are connected in parallel with each other and disposed toward the same direction. The unidirectional conductive elements are connected in serial to the battery packs, respectively. A positive pin of each of the unidirectional conductive elements is connected in serial to a positive terminal of the corresponding battery pack, and a negative pin of each of the unidirectional conductive elements is connected in parallel to negative pins of other unidirectional conductive elements. Therefore, the present disclosure is capable of preventing the battery packs having relatively lower voltages from being charged by the battery packs having relatively higher voltages, thereby prolonging lifetimes of batteries, and avoid from affecting power to be supplied to a power receiving circuit from the battery packs.
