Description

  The present invention relates to a portable illuminator that can be used as a portable illuminator that can be carried around, or can be used in a desired place by changing the location.

Various types of portable lighting fixtures have been proposed and put to practical use.
The oldest portable lighting fixtures include so-called flashlights that can be lit with dry batteries, but we also propose portable lighting fixtures that can be used as portable portable lighting fixtures, or can be used stationary. Has been put into practical use.

  For example, Japanese Patent Laid-Open No. 2010-73334 discloses that a power supply from an external power supply can be used as a lighting lamp by being always installed in a place where it can be connected to an external power supply. A portable LED (Light Emitting Diode) lamp is described which can be switched to a secondary battery and removed from the location and used as a flashlight.

  In Utility Model Registration No. 3164931, a flexible arm is raised from a base part, an illumination part including a light source is supported on the arm, and the base part can be placed at a desired location to be used as a stationary illumination device. A portable illumination device is described in which the flexible arm is wound around a groove provided on the outer periphery of the base portion to make the whole compact and can be used as a portable illumination device.

  An illumination device using a solar cell has also been proposed. For example, Japanese Patent Application Laid-Open No. 2008-192529 discloses an illumination device that uses a solar cell and a rechargeable secondary battery as a power source and uses an LED as a light source. Is described.
