[0003]

Such an illuminating device is convenient when it is used by suspending it as shown in FIG. 1 (B), but the fluorescent lamp is vertical as shown in FIG. 1 (C). When used upright so as to be oriented, only the front direction of the main body case 2 can be illuminated, and the circumference of the axis of the fluorescent lamp 2 cannot be uniformly illuminated over 360 degrees.
The manganese battery 4 has a small capacity and a short life.

On the other hand, the camera-integrated VTR uses a rechargeable battery, but the camera-integrated VTR is not always used and is generally used only in a limited time such as when something happens. The current situation is not. Therefore, it would be convenient if the rechargeable battery of the camera-integrated VTR could be used in this portable lighting device.

The object of the present invention is that it can be used as a conventional portable lighting device by attaching it to the front surface of the body case, and it can evenly illuminate in the direction of 360 degrees around the axis of the fluorescent lamp. It is to provide an illuminating device capable. Another object of the present invention is to allow the rechargeable battery used in a VTR with a built-in camera to be used as a power source for a portable lighting device.

[0006]

A portable lighting device according to the present invention comprises a battery and an oscillation circuit housed in a main body case, and a fluorescent lamp mounted on the front surface of the main body case. Is supported rotatably at one end thereof in a plane including the axis of the fluorescent lamp and perpendicular to the front surface of the main body case, between a direction parallel to the front surface of the main body case and a direction perpendicular to the front surface of the main body case. ing.

The fluorescent lamp may have electrodes only on one end side, or may have electrodes on both ends. In the case of a cylindrical fluorescent lamp having electrodes at both ends, the stopper at the base end is rotatably supported by the main body case, and the stopper at the tip end has at least two lead wires with respect to the stopper at the base end. It may be fixed by a metal rod that also serves as a terminal, and the terminals of the electrodes at both ends may be gathered on the base end side and connected to the oscillation circuit.

In a preferred embodiment, the battery is a camera integrated V
It is a rechargeable battery used in TR. In order to allow the rechargeable battery to be stored in the main body case, the lid on the back of the main body case can be opened and closed, and the terminals that come into contact with the electrodes of the battery are arranged inside the main body case. Biasing means for pushing the battery toward the terminal in the main body case is provided on the back side of the. In a further preferred embodiment, a spacer having a battery biasing means for adjusting the distance between the lid and the battery is movably attached to the back cover between the battery storage position and another position.

[0009]

When the fluorescent lamp is used while being housed in the main body case, it can be used to illuminate only the front direction of the main body case when illuminating while walking or while holding. By rotating the fluorescent lamp at its base end side, standing it upright in a direction perpendicular to the front surface of the main body case, and placing it on a table or the like, it becomes possible to uniformly illuminate 360 degrees around the axis of the fluorescent lamp. Camera integrated VTR

In the embodiment, the case where a cylindrical fluorescent lamp having electrodes at both ends is used as the fluorescent lamp 16 has been described as an example, but a fluorescent lamp that can be used is one having electrodes at both ends. There is not limited to this, but there is one in which the glass tube portion of the fluorescent lamp is bent into a U-shape or the like, and the electrodes at both ends can be put together in one place and attached to the socket. A fluorescent lamp having such an electrode only at one end can also be applied to the present invention.
In that case, one end side where the electrodes are collected may be rotatably attached to the main body case. In addition, a battery using a rechargeable battery of a camera-integrated VTR is illustrated as the battery. It is convenient if the battery can be charged, but the battery is not limited to the rechargeable battery.

[0021]

According to the present invention, the fluorescent lamp is housed in the main body case to illuminate the front direction, and the fluorescent lamp is erected vertically in the case to uniformly illuminate the circumference of the fluorescent lamp. Since it is made available, the applications of the portable lighting device are expanded and convenient. VT with integrated camera as a battery
If the rechargeable battery used in R can be used, it is possible to effectively use a battery that is rarely used normally. Also, if it can be charged, it can be used as many times as possible and waste of resources can be eliminated. By disposing the spacer on the case body at the battery mounting position or moving the spacer depending on the height of the battery, rechargeable batteries having different heights can be used with good compatibility.
