Has been implemented. The LED board 12 is wired so as to be connected to the secondary battery 31 and the switch 32. Improvement of light extraction efficiency can be expected by pasting a highly reflective sheet on the LED element mounting surface side or applying a highly reflective resin. Due to the shape of the LED substrate 12, the light from the LED element 11 is radiated uniformly and over a wide range.
As the light source, various known LED elements, organic EL elements, and the like can be used. In this embodiment, a high-luminance type LED element that emits white light for illumination is used.
The power supply board 13 is a glass epoxy board having a rectangular flat plate and copper foils on both sides, and electronic components constituting a circuit for controlling charging of the secondary battery 31 are mounted thereon. From the power supply board 13, the wiring connected to the secondary battery 31 and the charging socket 19 (FIG. 4, FIG. 5) into which the direct current for charging is input is provided.
As a result, the charging socket 19, the power supply board 13, and the secondary battery 31 form a single line, which is close to wiring and can be constructed with a reduced number of assembly members and man-hours. Further, depending on the shape of the power supply board 13, it is possible to make the wiring unnecessary by directly connecting the wiring of the charging socket 19, the power supply board 13 and the secondary battery 31 through the power supply board.

As shown in FIG. 4, a concave annular connecting portion 18 is provided at the tip of the cylindrical body 14, and a terminal of a charging adapter 40 for charging the secondary battery 31 is connected to the central portion of the connecting portion 18. A charging socket 19 is connected to the power supply board 13 and installed. A screw groove is formed in the outer peripheral portion of the connection portion 18, and the cab portion 15 is detachably screwed so as to cover the connection portion 18.
A handle 16 for hanging the portable light irradiator 100 is attached to the cap portion 15 so as to be housed along the outer peripheral surface of the cap portion 15. The handle 16 has a semi-annular shape and is attached to the tip of the outer edge of the tip portion with a screw or the like so as to have a movable function that can be stored in the cap portion 15. During normal use, the handle 16 is stored in the storage portion 17 of the cap portion 15 and can be used.
Since the connection portion 18 is covered with the cap portion 15 during normal use, the charging socket 19 is prevented from being contaminated with dust or the like. Thereby, it has a structure that can withstand the use of the portable light irradiator outdoors. Moreover, since it can be suspended using the handle 16, it can also be used as illumination at a fixed position such as a lantern.

The grip portion 30 is made of a resin casing in which a secondary battery 31 such as a battery and a switch 32 for turning on / off the portable light irradiator are provided. As the rechargeable secondary battery 31, a nickel metal hydride battery, a lithium battery, or the like is used. As the switch 32 for turning on / off the portable light irradiator, a push button type, a slide type or the like is used. When the switch 32 is turned on, a current flows from the secondary battery 31 to the LED substrate 12, and the LED element 11 emits light.
Further, if the switch 32 is a dust-proof type, the grip portion 30 has a structure covered with a resin casing and can be prevented from being contaminated with dust or the like. It is also possible to withstand use in the like.
Furthermore, by forming irregularities on the housing surface of the grip portion 30, it is possible to make the structure easy to grip and not slippery.

  The irradiation unit 10 and the grip unit 30 are integrally coupled to form a portable light irradiator 100. When connecting the irradiation unit 10 and the grip unit 30 and connecting the cap unit 15 and the connection unit 18 of the irradiation unit 10 using an O-ring or the like, a portable light irradiator that is dust-proof and drip-proof can be obtained.
