<First embodiment>
FIG. 1 is an explanatory diagram of the appearance of the portable lighting device of the present invention.

As shown in FIG. 1, the portable lighting device 1 has a lighting section 11, a handle 33, an upper main body section 31, and a lower main body section .

Two handles 33 are provided on the upper body portion 31 . This handle 33 can be used by being hooked on a hook, a branch, or the like, in addition to being held by the user.

The lower surface of the lower main body portion 35 is flat so that the portable lighting device 1 can be placed on a table or the like.
Also, the lighting section 11 is positioned between the lower body section 35 and the upper body section 31 .
The lower body portion 15 is provided with a USB terminal 13 and a power terminal 21 for connecting to a DC power adapter.

In this embodiment, the power supply terminal 21 is provided with an AC/DC converter outside, but in other embodiments in which an AC/DC converter is provided inside, it is a terminal connected to an AC power supply. It can be.
Furthermore, if the power supply terminal 21 is connected to a direct power supply, for example, in the case of an external charger or a solar battery, the other party to be connected may be a DC power supply.

The USB terminal 13 may be a USB terminal of various standards. In that case, the shape of the terminal may be changed (for example, USB type C).

FIG. 2 is an explanatory diagram of an example of the circuit configuration of the present invention.

As shown in FIG. 2, the circuit of the present invention has a dry battery folder 15, a USB terminal 13, an illumination unit 11, a storage battery 17, a storage battery switch 19, a booster circuit 21, a dry battery folder switch 23, and a power adjustment unit 25.

The dry battery holder 15 can accommodate, for example, three AA batteries (dry batteries) in series.
However, parallel operation is also possible. Further, the battery type may be of other types (such as AA, AA and AAA). Also, the number of batteries is arbitrary.

The USB terminal 13 may be, for example, a 5V1A USB output terminal. Furthermore, even if it is of another type, any type of terminal that provides general-purpose power may be used.
Mobile phones, smart phones, and other electronic devices can be used and charged via this USB terminal.
A power adjustment unit 25 is provided to raise the voltage/current of the USB terminal 13 to a predetermined level. Any type of booster circuit 25 may be used.
The power supplied to the USB illumination unit 11 is supplied from a storage battery 17, a dry battery placed in a dry battery holder 15, or the like.
Furthermore, if a power terminal 21, which will be described later, is connected to an external power supply, power may be supplied from the external power supply.

The illumination unit 11 may be of any type as long as it emits light by electric power. Preferably, an LED lighting device is suitable. However, it may be a fluorescent lamp or the like. However, in order to make the power last longer, the one with less power consumption is suitable.
The power supplied to the illumination unit 11 is supplied from a storage battery 17, a dry battery placed in a dry battery folder 15, or the like.
Furthermore, when a power terminal 21, which will be described later, is connected to an external power supply, the light may be directly emitted from the power of the external power supply.

The storage battery 17 is charged by an external power supply connected to the power supply terminal 21 . The external power can be stored only in the storage battery 17 at the time of charging, but it is also possible to store power in the storage battery 17 and supply power to the USB terminal 13 and the illumination unit 11 as described above.
The power of the storage battery 17 is supplied to the USB terminal 13 and the illumination section 11 when not connected to an external power source.

The power terminal 21 is connected to an external power supply (plus terminal and minus terminal). In this embodiment, an example in which the AC/DC conversion unit and the like are provided outside the portable lighting fixture 1 is described, but the AC/DC conversion device may be provided inside the portable lighting fixture 1 .

In addition, although not described in this embodiment, for example, a solar battery, a hand-cranked generator, or the like may be further provided.

The storage battery switch 19 is disconnected and used to prevent the external power supply from being supplied to the USB terminal 13 and the illumination unit 11 during charging with power from the external power supply. As described above, when power is supplied to the USB terminal 13 and the illumination unit 11 during charging, the power is used in the state of sound.
In addition, of course, when there is no external power source and the storage battery 17 supplies power to the USB terminal 13 and the lighting unit 11, it is used in the ON state.
Also, when the power of the storage battery is used and the dry battery contained in the dry battery folder 15 supplies power to the USB terminal 13 and the illumination section 11, the storage battery switch 19 is turned off.
This is because if the storage battery switch 19 is on (connected), the power of the dry battery will be used to charge the storage battery 17 .

The dry battery folder switch 23 is turned on (connected) when there is no power in the storage battery 17 and when the power terminal 21 is not connected to an external power supply (and when dry batteries are inserted in the dry battery folder 15). .
This is because, in other cases, if the dry battery is placed in a charged state, the dry battery may malfunction.
In other words, when the storage battery 17 runs out of power and power cannot be obtained from the outside, the power supply from the dry battery can be used to supply essential low power consumption electric appliances such as lights and mobile phones with the secured rechargeable battery. This is because it is a spare for driving and charging.
By doing so, it becomes possible to temporarily obtain electric power in the event that there is no electric power even after coping with the storage battery 17 in some emergency state.
Thus, the present invention provides a redundant system.

<Configuration and effects of the embodiment>
In the first aspect of the present invention, the lighting fixture 1 for personal use has a storage battery 17 that can be charged by an external power supply, a dry battery holder 15 that can be detached from a dry battery, and a lighting section 11. The lighting section 11 is , the power of the storage battery 17, and the power of the dry battery inserted in the dry battery holder 15 can emit light.
With such a configuration, even if the power of the storage battery 17 runs out, it is possible to supply power to the lighting and the minimum electrical appliances.

Preferably, it has a USB terminal 13 through which power can be supplied to the outside.
With such a configuration, it is possible to supply power to a USB device, particularly a mobile phone (smartphone) or the like.

The USB folder 15 can externally supply the power of the dry battery inserted in the dry battery folder.
With such a configuration, it is possible to supply power to a USB device, particularly a mobile phone (smartphone) or the like.

The circuit configuration, structure, positional relationship, materials, etc. of the present invention can be changed variously without changing the gist of the present invention.
For example, two or more members can be combined into one, or conversely, one member can be configured from two or more different members and connected.
Moreover, the above-described embodiment is merely one of the best modes at present.
