Therefore, its application will dramatically expand compared to conventional portable lighting devices, and it is not only used for various leisure and disasters, but also for use at construction sites and construction sites, and daily life at home. The range of use can be expected even for use.

  In addition, by using the portable lighting device 1 in the present embodiment described above, the lighting output is automatically adjusted to save energy. In particular, in the portable lighting device 1 according to the present embodiment, since the electric power generated by the solar panel 13 is used as the power source of the lighting unit 50, the power can be made more efficient by adopting the above configuration. By using it frequently, it is possible to prevent the occurrence of a situation where power is insufficient during use and the use cannot be performed or a situation where it is necessary to frequently charge the battery.

  In addition, in this Embodiment mentioned above, although the case where it comprised so that illumination intensity might be adjusted by controlling lighting / non-lighting of several LED group separately, adjustment of illumination intensity using another method is demonstrated. May be performed. For example, the LED may be configured to emit light by PWM (Pulse Width Modulation) control, and the illuminance may be adjusted by adjusting the duty ratio as necessary.

  Further, in the present embodiment described above, the case where the illuminance of the LED is adjusted according to the position of the rotating member is exemplified, but it is not always necessary to configure in this way, and the rotating member is simply used. Depending on the position, all the LEDs may be turned on / off.

  Further, in the above-described embodiment, the case where the charging operation is not performed when the LED is turned on is exemplified. However, such a configuration is not necessarily required, and the charging operation is also performed when the LED is turned on. May be configured to be performed.

  Further, in the above-described embodiment, the case where the position of the rotating member is fixed in stages is illustrated, but the position of the rotating member may be fixed at an arbitrary position. Good. In that case, the rotatable range of the rotating member is divided for each predetermined angle, and when the rotating member is located within the divided range, the lighting unit or the like performs an operation according to the range. What is necessary is just to comprise.

  Note that the relationship between the position of the rotating member and the operation of the lighting unit 50 and the like shown in the present embodiment described above is merely an example when the present invention is applied, and the shape of the apparatus main body, the shape of the rotating member, The position can be appropriately changed according to the mounting position of the rotating member with respect to the apparatus main body, the configuration of the illumination unit, and the like.

  Thus, the one embodiment disclosed this time is illustrative in all respects and is not restrictive. The technical scope of the present invention is defined by the terms of the claims, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
