[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flashing warning device that can be used to call the attention of a driver of a moving vehicle at a road construction site, an accident site, a traffic control site, or the like.

[0002]

2. Description of the Related Art Conventionally, in a central portion of a concave mirror which is circular in a front view and curved in a spherical shape or a parabolic shape,
A rotation warning lamp provided with a rotation lamp such that its rotation axis substantially coincides with the center line of the concave mirror is manufactured and sold by the present inventor and is well known (for example, Japanese Patent Publication No. 49-92).
No. 80).

In such a rotation warning light, as described above, the concave mirror has a circular shape when viewed from the front side of the viewer, and most of the turning rays emitted from the rotation light are substantially parallel. It was designed to go straight to or converge at a distance. Further, a part of the turning light beam is radially emitted from through holes that are annularly arranged at equal intervals.

Further, a blinking floodlighting device has been proposed in which a plurality of plane mirrors are annularly arranged in a concave housing (see Japanese Utility Model Laid-Open No. 63-182003). In such a blinking light projecting device, the turning light beam emitted from the rotating lamp does not become a parallel light beam but rotates intermittently and has a spread in the irradiation direction.

Furthermore, in any of the above devices,
A rotating lamp using an incandescent light bulb and a large reflecting mirror are indispensable constituent members, but since the rotating lamp is equipped with a light emitting unit and a rotation driving unit, it becomes inevitably taller, and as a result, The entire device became thick and the reflecting mirror became an unstable element, and it was impossible to load it.

[0006]

As described above, in the former technique, the turning ray radiated from the rotating lamp is simply converted into the rotating ray, and the locus of the rotating ray is monotonous. Even if it is only a rotating light beam, it is possible to call the viewer's attention to some extent, but the trajectory is monotonous. .

In the latter technique, the swirling light beam emitted from the rotating lamp is not a parallel light beam and has a spread in the irradiation direction, so that it is not a simple rotating light beam, but the structure is complicated and the cost is high. It also has a drawback that it becomes heavy and difficult to carry.

Further, as described above, a rotating lamp and the like are indispensable constituent members in any of the devices, but since the rotating lamp is provided with a rotation driving unit, it is necessarily taller. There is a problem in that the entire device becomes thick and the concave mirror becomes an unstable element, so that the device cannot be loaded and is difficult to carry.

Furthermore, since all the prior arts use an incandescent lamp, there is a problem that not only the size is increased but also the life is short. The present invention has been made in view of such difficulties, and is intended to realize a flash warning light and a flash warning device which are small and thin and which can change the flash light without using a known rotary light. is there.

SUMMARY OF THE INVENTION According to the present invention, there is provided a base having an annular bottom formed by forming a side wall rising to the front on the outer periphery and forming a front protrusion in the center. The blinking warning device is characterized in that a light reflecting member having a plurality of blinking light emitting diodes fixed thereto is attached to an annular bottom portion.

[0013]

In any of the inventions, the light-reflecting member whose rear surface is diamond-cut is equipped with a light-emitting diode. Some of the light rays emitted from the light-emitting diode go straight, and the rest are diamond-cut surfaces. It will be diffusely reflected and will shine brilliantly. Further, since the light emitting diode is controlled so as to flash as appropriate, the light emission locus can be formed in a desired shape. Further, since the revolving light is not provided, the whole device is thin.

First, the blinking warning light will be described. Reference numeral 4 denotes a circular optical generator 4 which is a light-reflecting member having a diamond cut on the back surface. The center of the optical generator 4 projects slightly forward, and twelve small holes 7 are annularly and radially arranged. The heads of the light emitting diodes 8 are inserted into and fixed to the small holes 7 from the back side. In this case, if the head of the light emitting diode 8 is fixed at a position where it does not project from the surface side of the optical generator 4, diffused reflection light increases and the viewing angle widens. 5 is a mounting screw

The optical generator 4 is made of a transparent resin or glass, and a large number of quadrangular pyramid-shaped irregularities are formed (diamond cut) on the back surface of a substrate which is colorless or colored red or yellow. It is a well-known one that is mounted on the back of a bicycle or an automobile.

The outer diameter of the light emitting diode 8 is substantially equal to the inner diameter of the small hole 7, and the head of the light emitting diode 8 is press-fitted into the small hole 7. The outer diameter of the light emitting diode 8 is smaller than the inner diameter of the small hole 7, and the light emitting diode 8 may be fixed to the small hole 7 with an adhesive while being inserted.

As described above, when the head of the light emitting diode 8 is inserted into the small hole 7 of the photogenerator 4, a part of the light beam emitted from the light emitting diode 8 goes straight forward, and the rest is light. The light is diffused and refracted inside the generator 4 and is irradiated forward, so that the viewer is irradiated with a complicated and varied light beam.

In the second embodiment of FIG. 2, a battery case 12 accommodating a battery 13 is fixed to the back surface of the optical generator 4 of the first embodiment by a nut 6 and a screw 5, 13 and the lead wire 14 of each light emitting diode 8 are electrically connected. When configured in this manner, it can be generally carried like a flashlight.

In the third embodiment of FIG. 3, the light emitting diode 8 is fixed so that the head of the light emitting diode 8 is located on the back side of the small hole 7. With such a structure, diffused reflection light is further increased and the viewing angle is widened as compared with the above embodiment.

Next, the blinking warning light of the first embodiment is 6
A first application example in which individual pieces are arranged will be described with reference to FIGS. 4 to 7. Reference numeral 1 denotes a disk-shaped base which is integrally formed with a side wall 2 on the outer periphery, and a central portion thereof is formed in a truncated cone shape so as to project forward. Further, six optical generators 4 of the first embodiment are mounted on the annular bottom portion around the projecting portion 3 at equal intervals. In this optical generator 4, twelve small holes 7 are arranged annularly and radially, respectively, as described above.
A light emitting diode 8 is fitted in each of the small holes 7.

The portion of the base 1 on which the optical generator 4 is not mounted is colored in a dark color such as black, so that the light emitted from the light emitting diode 8 is made to stand out.
The optical generator 4 may be configured so as to float slightly forward from the inner bottom portion of the base 1.

On the rear surface of the base 1, the light emitting diode 8 in which a telescopic pole 9 of a tripod is fixed by a metal fitting 10 is
As shown by the black dots in FIGS. 6 and 7, the light emission timing is controlled so that the groups at mutually symmetrical positions blink at the same time, and their light emission loci rotate in the direction shown by the alternate long and short dash line. The light emission loci of each group may be controlled to rotate, or all the light emitting diodes 8 may be controlled to blink simultaneously. The lighting state may be continued.

Next, a second application example will be described with reference to FIGS. 8 and 9. In this second application example, the same parts as those in the first application example are designated by the same reference numerals, and detailed description thereof will be omitted. In this second application example, an annular transparent cover 11 is detachably attached to the front surface except the protruding portion 3. The cover 11 does not necessarily need to be completely transparent, but a semi-transparent cover 11 can be used.

The light emitting diodes 8 may be arranged in various shapes such as a triangle or a rhombus instead of the shape described above, and the number and size of the light emitting diodes 8 may be changed. In addition to a so-called AC100V commercial power source, a battery or a solar cell can be used as the power source.

[0026]

In any of the inventions, a plurality of light emitting diodes are mounted on the reflecting member, and the light emitting diodes are controlled so as to blink in an appropriate form and emit light.
The light emission locus can be formed into a desired shape. Therefore, the locus of light emission becomes complicated, and the viewer can be sufficiently alerted. In particular, since it is possible to change the light emission locus of the light emitting diode depending on time, it is possible to prevent so-called rut.

Further, since the rotating lamp is not necessary, the whole apparatus can be made thin, and since there is no concave mirror, the apparatus can be loaded stably. Therefore, it is possible to reduce the size and
Easy to carry.

Further, since the optical generator and the light emitting diode are used, it is possible to realize an inexpensive blinking warning lamp or blinking warning device having a long life and a high reflection intensity.
