2. Description of the Related Art Portable illuminators equipped with a cylindrical translucent cover that radiates the light emitted from a light source at the tip of a handle with a built-in dry battery are mainly used for traffic control by radiating red light. It is used to display accidents.

In this well-known portable lighting device, the translucent cover body is colored red so as to exhibit a red color when the light emitted from the light source is transmitted, or the translucent cover body is colorless or light-colored. The light emitted from the red light source is transmitted as it is, so it is necessary to pay attention, and it is usual to make the translucent cover body quite long so that it can be easily recognized from a distance at night or in a dark place. .

As described above, in the case of a general flashlight in which a light source such as a small light bulb is arranged at the tip of the handle having the long light-transmitting cover attached, the long light-transmitting cover is entirely covered. Since it is not possible to disperse the light almost evenly over
As shown in FIG. 4, the two electrode rods 5 are inserted from the tip of the handle 51.
2 and 52 are projected in parallel to form a plurality of light emitting diodes 5
3 is connected at an appropriate interval, arranged in parallel, and covered with a translucent cover body 54 for practical use. Even if it is quite long, it is possible to disperse light almost uniformly from the whole. Is.

However, since the handle has two or three dry batteries arranged in a line and built in and can be held by one hand, it has almost the same size and shape, but is transparent. The optical cover body is made in various lengths depending on the use, place of use, convenience of carrying and using.

Therefore, as described above, in the case where the plurality of light emitting diodes 53 are connected in parallel using the electrode rods 52, 52, the light is diffused substantially evenly over the entire length of the transparent cover body 54. Since it is necessary to prepare a plurality of types in which the light emitting diode 53 is combined with the electrode rods 52, 52 having different lengths according to the length, it is not only difficult to manage in the manufacturing process, but also the manufacturing price can be reduced. There is a problem that you cannot hold it down.

[0007]

The problem to be solved by the present invention is that a plurality of light sources are arranged at appropriate intervals in the longitudinal direction inside a long light-transmitting cover body attached to the tip of a handle. A conventional portable lighting device that is made to disperse almost evenly has a structure in which a light source such as a light emitting diode is combined with an electrode rod and covered with a light-transmitting cover body. In order to correspond, it is necessary to prepare a plurality of types of electrode rods having different lengths, which is troublesome to manage and cannot be provided at low cost.

[0008]

In order to solve the above problems, the present invention provides at least one rod-shaped member having at least one connecting portion for connecting with each other and arranging them in a straight line, and having at least one light source. And a light source support consisting of two parts is made to protrude while holding the base end at the tip part of the handle with a built-in dry cell, and a light-transmitting cover body having substantially the same length as the light source support covers the light source support. And the base end is held by the tip of the handle, or in addition to this, the tip of the light source support is connected to the tip surface of the translucent cover, and by such means The purpose of the present invention is to provide a portable illuminator having different lengths of light emitting portions easily and at low cost.

[0009]

[Function] When the light source connected to the dry battery is turned on, the light emitted from the light source is transmitted through the translucent cover body to be dissipated and the signal,
Warning or lighting. The light-transmitting cover has a length that is approximately an integral multiple of the length of the rod-shaped member, and the light source support is composed of one rod-shaped member or a plurality of rod-shaped members that are combined and arranged in a straight line according to the length of the light-transmitting cover. Will be almost evenly dissipated.
