Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable signal light for giving a signal to a vehicle running on a road, a construction site or the like to stop or advance.

[0002]

2. Description of the Related Art A conventional portable signal light is, for example, a conventional example 1.
As a light-emitting diode as a light-emitting body is arranged in a plurality of axial directions in a transparent cylindrical body, the transparent cylindrical body is a semitransparent outer cylinder made of red or orange provided with diffusion means such as irregularities and narrow grooves. There is one that is stored and used by blinking the light emitting diode. In addition, as a conventional example 2, a light emitting diode of a plurality of colors such as a red light emitting diode and a green light emitting diode is provided as a light emitting body, and the light emitting color is selected by a changeover switch (for example, the actual development 1- No. 168902), and in Conventional Example 3, the cylindrical body irradiated by the light emitting body is color-coded into two or more colors, and the light emitting body is switched to selectively irradiate (for example, actual kaihei 1
-130202) and the like.

[0003]

In the structure of the prior art example 1 in which the light emitting diode is arranged as described above, the emission color is only one color of red which originally means stop, and the advance and stop are the operations of the signal light by the guider. Was represented by. Therefore, the driver or pedestrian must judge the meaning of stopping or advancing depending on how the guider swings the signal light. However, the guider does not always guide correctly, and even if the guider correctly guides, there is a case where the guider makes a mistake or does not know how to make a judgment in the case of a quick start. Also, it was very difficult to understand the direction in which to proceed.

Further, when a light emitting diode of a plurality of colors is used as a light emitting body as in the conventional example 2, by selecting the emission color, there is no misunderstanding due to the ambiguity or misunderstanding of the signal as in the case of one color of red. However, there is a problem that it is difficult to see the emission color other than red because it is irradiated by the entire cylinder. Especially in the daytime, it is difficult to see. Further, in the case where the cylindrical body is color-coded as in the case of the conventional example 3, the display portion becomes smaller and the entire cylindrical body irradiates the light so that it is visually blurred in the case of a green color other than red. Difficult to do. In any case, even though the conventional example uses multiple light bulbs or light emitting diodes, each light source is not visible individually, so even if the light source blinks It was not always possible to confirm clearly even with the.

The present invention has been made in view of the above circumstances, and an object thereof is to use a light emitting diode of a plurality of colors and to stop, advance, etc. by emphasizing the contrast of each light source. The purpose of the present invention is to provide a portable signal light that makes it easy to understand the meaning and accurately conveys the directionality when proceeding.

That is, the portable signal light according to claim 1 of the present invention accommodates a lamp unit having a plurality of light emitting diodes that flash and emit strong light as a light emitting unit and a battery, and switches the power switch and the light emitting color of the light emitting diode. In a portable signal light including a grip portion having a switch, the light portion includes a reflector in which two or more rows of light emitting diodes that form a light emitting portion are axially attached at regular intervals, and a transparent tube that houses the reflector. Further, it is characterized in that it comprises an opaque protection tube for accommodating the transparent tube, a through hole is bored in a portion of the protection tube where the light emitting portion is located, and a tip is covered with a cap.

A portable signal lamp according to a second aspect is characterized in that light emitting diodes of a plurality of colors are collectively used as a light emitting portion, and these light emitting portions are attached to respective surfaces of a reflector which is a substantially triangular hollow body at regular intervals. And Further, in the portable signal light according to claim 3, light emitting diodes of a plurality of colors are collectively used as a light emitting part, and these light emitting parts are attached to each reflecting mirror of a reflector formed by fixing a reflecting mirror to a cylindrical support. Is characterized by. Further, in the portable signal light according to claim 4, a light emitting diode of one of two colors is attached as a light emitting portion to one surface of a reflector having two reflecting surfaces formed in a front-back relationship. The light emitting diode of the other color is attached to the other surface as a light emitting portion. Furthermore, the portable signal light according to claim 5 is characterized in that the shape of the through hole in the protective cylinder is two or more.

[0008]

It is possible to grasp the blinking and the direction of the blinking quickly and accurately. Furthermore, the opaque protective tube enhances the contrast of the emission color, which can be clearly confirmed even in the daytime. Further, according to the second aspect, since the light emitting portion is configured by integrating the light emitting diodes of a plurality of colors, by using the light emitting diodes of the respective red, yellow and green light emitting colors, the red color is stopped and the yellow color is cautioned. The green color can be operated in the same way as a normal road signal light for driving.

In the third aspect of the invention, since an independent reflecting mirror is used for each light emitting section, the irradiation becomes stronger and the emission color can be easily confirmed. According to the fourth aspect, different signals can be sent in two directions at the same time by blinking the light emitting diodes of two colors at the same time. further,
According to the fifth aspect, the meaning of the signal can be recognized more clearly by the shape of the through hole, which is particularly effective in the daytime.

The reflector 7 is a hollow rod-shaped body having a substantially triangular cross section, and each surface is formed in a groove shape with a curved surface. The reflector 7 is formed by continuously forming a reflecting mirror that reflects light more brightly, and the structure can be simplified and the cost can be reduced as compared with a case where the reflecting mirror is provided independently for each light emitting portion. The light emitting portion 5 is axially attached to each surface of the reflector 7 at appropriate intervals, and lead wires wired in the hollow portion are connected to a switch or a battery provided in the grip portion 3.

The reflector 7 to which the light emitting section 5 is attached is housed in a transparent tube 9.

The transparent tube 9 is further housed in the protective cylinder 10. The protective tube 10 is an opaque body, and the peripheral surface thereof has through-holes 2 at the same intervals as the mounting positions of the light emitting portions 5.
0 is drilled. Therefore, the light emitting portion 5 is located substantially at the center of the through hole 20 and is irradiated through the transparent tube 9.
Since the light emitting portions 5 are individually viewed by the through holes 20 when they are turned on, blinking of the light emitting portions 5 and the direction of blinking can be grasped quickly and accurately.

Further, since the color of the outer peripheral surface of the protective cylinder 10 can enhance the contrast of the emission color of each light emitting portion 5, the meaning of the signal emitted can be clearly read. Since the protective cylinder 10 may be made of an opaque material, its strength is improved by forming it from plastic, metal, or the like.
A signal lamp with excellent durability can be obtained. The tips of the reflector 7, the transparent tube 9 and the protective cylinder 10 are integrally fixed by a cap 11. The cap 11 is

FIG. 7 shows a second embodiment relating to the portion of the protective cylinder 10 in the case where the emission color is changed for each row, and is a developed plan view in the case where the shape of the through hole is changed.

That is, the through hole in which the red light emitting diode in the first row is located is a circular through hole 20a, and the through hole in which the yellow light emitting diode is in the second row is a square through hole 20b, and the green light emitting diode in the third row is Is a triangular through hole 20.
This is the case where c is set. In this way, when the shape of the through hole is changed according to the color of light emission, the meaning of the signal can be recognized also by the shape, and it is possible to prevent accidents due to inaccuracy or misunderstanding of the signal.
