With the spread of high-brightness, power-saving, small-sized LED elements, small-sized batteries such as button batteries have come to be practically used as their driving sources. On the other hand, in the event of a disaster or emergency, cylindrical dry batteries generally called AA, AAA, or AAA type are used in consideration of long-term use and availability. is desired. And even with such a dry battery, it is required to make the small LED light more compact. In addition, it is also required that operability is not sacrificed in miniaturization.

The present invention has been made in view of the above situation, and its object is to enable long-time driving using a cylindrical dry battery, and to attach and detach freely to a hat or the like by a clip mechanism that clamps the fixing point. To provide a small portable LED light which is attachable, compact and excellent in operability.

A portable LED light according to the present invention is a portable LED light that can be detachably mounted with a clip mechanism that clamps a fixing point, and has one main surface fixed or integrated with the clip mechanism and a vertical a plate-like base having a shaft extending vertically; and a main body having an axis and supported by the shaft so that the axis is perpendicular to the main body so as to be rotatable in a plane parallel to the main surface. and an LED light emitting part combined with the main body so as to be rotatable about the axis, wherein the LED light emitting part is biaxially rotatable with respect to the base by the shaft and the axis. A columnar dry battery that is supported and supplies power to the LED light emitting portion is arranged along the axis.

According to this feature, a portable small LED light that is compact and excellent in operability can be obtained by using a cylindrical dry battery.

1 is a side view of an LED light in one embodiment according to the invention; FIG. 1 is a rear view of an LED light in one embodiment according to the present invention; FIG. FIG. 10 is a cross-sectional view of a main part of an LED light in another embodiment;

A portable LED light as a representative example of the present invention will be described below with reference to FIGS. 1 and 2. FIG.

As shown in FIGS. 1 and 2, the LED light 10 includes a clip mechanism 1 for fixing the LED light 10 by sandwiching a fixing portion, a body portion 2 rotatably attached to the clip mechanism 1, and a body portion. and an LED light emitting part 3 further rotatably mounted with respect to 2 .

More specifically, the clip mechanism 1 has one of a pair of plate-shaped gripping portions 11 as a base, and a shaft 12 extending perpendicularly to the outer main surface of the base is implanted. . The shaft 12 pivotally supports the main body 2 and is rotatable. That is, the body portion 2 rotates within a plane parallel to the main surface of the grip portion 11 . The body portion 2 further has an axis A perpendicular to the direction in which the shaft 12 extends. A pair of bearing portions 21 are provided at both ends of the body portion 2 along the axis A, and support a pair of shaft portions 31 provided at both ends of the LED light emitting portion 3 combined with the body portion 2. The LED light emitting part 3 is rotatable with respect to 2 . In other words, the LED light-emitting portion 3 is biaxially rotatably supported by the shaft 12 and the axis A with respect to the grip portion 11 that is the base. In addition, each rotation support part is applied with a load that suppresses rotation to such an extent that it does not rotate by its own weight, and can be stopped at an arbitrary rotation angle. Thereby, the orientation of the LED light emitting portion 3 can be arbitrarily adjusted.

The clip mechanism 1 is provided so that the main surfaces of a pair of gripping portions 11 face each other with a gap therebetween. The pair of gripping portions 11 are supported via an arm 13 extending toward each other at substantially the center in the longitudinal direction and a rotating shaft body 14 that rotatably supports the arms 13, and both ends in the longitudinal direction are brought close to each other. Alternatively, they can be rotated like a seesaw so as to separate them. Further, the grip portion 11 is biased by a spring 15 in a direction in which the rear end portion 11b, which is one end portion in the longitudinal direction, is separated from each other. The spring 15 is a torsion coil spring whose end is fixed by a stopper 17 provided on the inner surface of the grip portion 11 .

As a result, the front ends 11a of the grips 11 are urged toward each other, and the clamping portion 16 provided on the inner side near the front ends 11a can pinch a fixing portion such as a member for mounting the LED light 10 thereon. can. It is also preferable to apply a soft resin such as rubber to the surface of the pinching portion 16 to make it difficult to slip on the fixed portion. As described above, one grip portion 11 is used as a base, but a separate body fixed to the grip portion 11 may be used as a base. That is, the shaft 12 may be provided on another plate-like body fixed to the grip portion 11 .

The body portion 2 includes a body support portion 22 extending along the axis A, and a pair of bearing portions 21 formed so as to extend from both longitudinal ends of the body support portion 22 toward the opposite side of the grip portion 11 . . The main body support portion 22 is supported so that the shaft 12 is inserted through it at substantially the center in the longitudinal direction. The bearings 21 pivotally support the pair of shaft portions 31 of the LED light emitting portion 3 as described above, and allow the LED light emitting portion 3 to rotate about the axis A. As shown in FIG.

The LED light emitting unit 3 includes an LED 33 having an optical axis perpendicular to the axis A and a reflecting plate 32 arranged around the LED 33, and contains a dry battery 34 for supplying power for causing the LED 33 to emit light. The dry battery 34 is cylindrical, and typically cylindrical dry batteries called AA, AAA or AAA type can be used. The dry battery 34 is arranged with its longitudinal direction along the axis A, and both ends thereof are positioned inside the shaft portions 31 . In other words, the dry battery 34 is included as a part of the rotary shaft formed by the shaft portion 31, so that the arrangement is made compact. Also, it is preferable that the inner peripheral surface of the shaft portion 31 is sized so as to be in contact with the outer peripheral surface of the dry battery 34 . In this case, the dry battery 34 can bear a part of the rigidity of the rotary shaft due to the shaft portion 31, and the thickness of the shaft portion 31 can be reduced, contributing to a compact arrangement.

The LED light emitting part 3 has a cover 35 on the end surface of the shaft part 31 so that the dry battery 34 can be taken out from the inside and replaced. An electrode in contact with the dry battery 34 is provided on the rear surface of the lid 35 and electrically connected to a circuit (not shown) for lighting the LED 33 .

Moreover, it is preferable that the switch unit 36 that controls lighting of the LED 33 is a button switch that is pressed along the axis A. As shown in FIG. In this case, the operation of the switch section 36 is less likely to change the orientation of the LED light emitting section 3 with respect to the clip mechanism 1, and the LED light emitting section 3 can be stably used while the direction thereof is arbitrarily adjusted.

As described above, according to the LED light 10, the LED light emitting part 3 is biaxially rotatably supported by the shaft 12 and the axis A with respect to the grip part 11, which is the base, and the optical axis can be adjusted in any direction. obtain. In other words, a compact portable small LED light can be obtained by using the cylindrical dry battery 34 which is excellent in operability and enables long-time driving as compared with a button battery.

In particular, by using the clip mechanism 1, it is possible to attach it to belongings such as hats, bags, and other fixed objects in general. Here, in fixing by the clip mechanism 1, the orientation of the clip mechanism 1 is limited to some extent depending on the shape of the fixing portion. On the other hand, according to the LED light 10, the orientation of the optical axis of the LED 33 can be arbitrarily adjusted by supporting the biaxial rotation. As a result, the user of the LED light 10 can easily adjust so as to irradiate the light in a desired direction.

As shown in FIG. 3, the lid 35 may be attached to the bearing 21 of the main body 2. As shown in FIG. In the example described above, the cover 35 is attached to the shaft of the LED light-emitting portion 3, but is attached to the main body 2 here. Therefore, when the LED light emitting portion 3 is rotated with respect to the main body portion 2 , the electrode provided on the back surface of the lid 35 rotates with respect to the shaft portion 31 and the dry battery 34 .

Therefore, for example, a negative electrode 41 made of a compression coil spring is provided at the center of the back surface of the lid 35 and brought into contact with the negative electrode of the dry battery 34 . On the other hand, the positive electrode 42 that contacts the positive electrode of the dry battery 34 extends along the inner peripheral surface of the shaft 31 toward the negative electrode and is bent outward at the end of the shaft 31 . Then, the bent portion of the positive electrode 42 is brought into contact with the slide contact 43 provided on the rear surface of the lid 35 . The slide contact 43 is arranged in an annular shape on the back surface of the lid 35 and is always in contact with the positive electrode 42 that rotates as the shaft 31 rotates. As a result, even when the dry battery 34 rotates around the axis A together with the shaft 31, the contact of the circuit for lighting the LED to the negative electrode 41 and the positive electrode 42 can be maintained.

Although the embodiments according to the present invention and modifications based thereon have been described so far, the present invention is not necessarily limited to these examples. Also, those skilled in the art will be able to find various alternatives and modifications without departing from the spirit of the invention or the scope of the appended claims.
