Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a flashing warning device that can be used to call the attention of a driver of a moving automobile at a road construction site, an accident site, a traffic control site, or the like.

[0002]

[Prior art]

 Conventionally, a rotating lamp is provided at the center of a concave mirror which is circular in a front view and curved in a spherical shape or a parabolic shape so that its rotation axis is substantially aligned with the center line of the concave mirror. The rotating warning light is manufactured and sold by the inventor of the present invention and is well known (see, for example, Japanese Patent Publication No. 49-9280).

In such a rotation warning light, as described above, the concave mirror has a circular shape when viewed from the viewer located on the front side, 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 arranged in a ring at equal intervals.

Further, there has been proposed a blinking floodlighting device 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 floodlighting device, the turning light beam emitted from the rotating lamp does not become a parallel light beam, but intermittently rotates and has a spread in the irradiation direction.

Furthermore, in any of the above devices, a rotating lamp using an incandescent lamp and a large reflecting mirror are essential constituent members, but the rotating lamp includes a light emitting unit and a rotation driving unit. Therefore, it is inevitably taller and, as a result, the entire apparatus becomes thicker, and the reflecting mirror becomes an unstable element and cannot be loaded.

[0006]

As described above, in the former technique, the turning ray emitted from the rotating lamp is simply converted into the rotating ray, and the locus of the rotating ray is monotonous. Even if only the rotating ray is used, it is possible to call the viewer's attention to some extent, but since the trajectory is monotonous, there is a problem that if it is used too much, it becomes so-called rut and the alerting power decreases. .

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, in any of the devices, the rotating lamp and the like are indispensable constituent members, but since the rotating lamp is provided with the rotation driving unit, it is necessarily tall. In addition, the entire device becomes thick, and the concave mirror becomes an unstable element, making it difficult to load and difficult to carry.

Furthermore, since all the prior arts use an incandescent light bulb, there is a problem that the life is short as well as the size is increased. The present invention has been made in view of the above problems, and it is an object of the present invention to realize a flash warning light and a flash warning device which are small and thin, which can change the flashing light without using a known rotary light. is there.

[0010]

[Means for Solving the Problems]

 The first main idea is that a through hole is formed in a light reflecting member having a diamond cut on the back surface, and the head of a light emitting diode that blinks and emits light is inserted into the through hole from the back surface side. It is a flashing warning light.

A second main idea is that a light reflecting member having a diamond cut on the back surface is provided with a through hole, and a head portion of a light emitting diode that blinks and emits light is provided on the back surface side of the through hole. It is a blinking warning light characterized by being

A third main idea is that the blinking warning lights are intermittently arranged in an annular shape on a disk-shaped base having a side wall formed on the outer periphery, and control is performed so that each blinking warning light flashes and emits light. It is a flashing warning device.

[0013]

[Action]

 In each of the inventions, a light-reflecting member whose back 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 irregularly reflected by the diamond-cut surface. Then it will shine brilliantly. Further, since the light emitting diode is controlled so as to flash as appropriate, the light emission trajectory can be made into a desired form. Further, since the revolving light is not provided, the whole device is thin.

 1 to 3 show an embodiment of a blinking warning light of the present invention, FIG. 1 is a sectional view of a first embodiment, FIG. 2 is a sectional view of a second embodiment, and FIG. 3 is a third embodiment. FIG. 4 to 9 show an application example of a blinking warning device to which the blinking warning light is applied, FIG. 4 is a front view of the first application example, FIG. 5 is a sectional view of the first application example, FIG. 6 and FIG. 7 is a front view showing a light emitting portion of the light emitting diode. 8 and 9 show a second application example, FIG. 8 is a front view, and FIG. 9 is a sectional view.

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 12 small holes 7 are annularly and radially arranged. The heads of the light emitting diodes 8 are inserted and fixed in 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 item that is installed on the back of bicycles and automobiles.

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 may be 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 ahead, and the rest is left. The light is diffusely reflected and refracted inside the optical generator 4 and is irradiated forward, so that the viewer is irradiated with complicated and varied light rays.

In the second embodiment of FIG. 2, the battery case 12 accommodating the battery 13 is fixed to the back surface of the optical generator 4 of the first embodiment by the nut 6 and the screw 5, The battery 13 and the lead wire 14 of each light emitting diode 8 are electrically connected. When so configured, it can generally be 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 surface 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, a first application example in which the six blinking warning lights of the first embodiment are arranged will be described with reference to FIGS. 4 to 7. Reference numeral 1 is a disk-shaped base having an integrally formed 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 attached to the annular bottom portion around the protrusion 3 at equal intervals. As described above, each of the twelve small holes 7 is annularly and radially arranged in the optical generator 4, and the light emitting diode 8 is fitted into each of the small holes 7.

A portion of the base 1 on which the optical generator 4 is not mounted is colored in a dark color such as black, and is configured so as to make the light emitted from the light emitting diode 8 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 back surface of the base 1, a telescopic pole 9 of a tripod is fixed by a metal fitting 10. The light emitting diodes 8 are symmetrical to each other as shown by black dots in FIGS. 6 and 7. The light emission timing is controlled so that the groups flash at the same time, and the light emission loci rotate in the direction indicated by the alternate long and short dash line. However, the light emission loci of each group may be controlled to rotate, or the total light emission. The diodes 8 may be controlled so as 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 translucent cover 11 can be used.

The arrangement of the light emitting diodes 8 is not limited to the above-described shape, but various shapes such as a triangle and a rhombus can be considered, and the number and size thereof can be changed. In addition to a so-called AC100V commercial power source, a battery or a solar battery can be used as the power source.

[0026]

[Effects of the Invention] 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 and emit light in an appropriate form, so that the light emission track has a desired form. be able to. Therefore, the light emission locus becomes complicated, and it is possible to call the viewer's full attention. 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 stably loaded. Therefore, miniaturization can be realized and transportation becomes easy.

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.
