Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the use of a plurality of strips of light or arbitrary patterns as a means for notifying the position of a road sign or the like at dusk or at night, or for recognizing traffic control, checking, or processing an accident. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road-recognition-marking light-emitting device that can effectively and widely notify the surroundings by indicating a light on a road.

[0002]

2. Description of the Related Art Conventionally, various road signs and signs are provided or provided for smooth running and safety of traffic. However, at dusk or at night, the visibility of the above-mentioned road signs and the like is high. Gets worse. Therefore, especially in the case of a traffic sign in a place where traffic is congested or in an accident-prone area, a dedicated lighting device is provided to make the sign easy to see.

[0003] In the art disclosed in the art, various techniques are disclosed as the illuminating device aimed at, including Japanese Patent Application Laid-Open Nos. H8-185702 and H11-111032.

[0004] The technology described above will be described more specifically. The technology disclosed in Japanese Patent Application Laid-Open No. H8-185702 effectively irradiates light radiated from a light source only to an illuminated object such as a road sign or an advertising signboard. This is a floodlighting illuminator provided with a mask that can limit the light emitted from the opening of the floodlight.

Similarly, in the technique disclosed in Japanese Patent Application Laid-Open No. H11-111032, illumination can be limited to only a specific illuminated object such as a road sign, and the illumination range can be easily adjusted. This is a technology of a lighting device for a road sign that can prevent a decrease in illuminance by reducing the number of components.

[0006] Further, in traffic control, inspections, accident handling sites, etc., a reflective tape is attached to a red cone, a color cone equipped with a light bulb is placed in the red cone, and red and yellow flashing lights, tail lamps and the like are used. Although the visibility is improved by arranging an annunciator and a light projecting device, various types of objects, including the above-mentioned publicly disclosed technology, for the purpose of improving the visibility to many drivers and pedestrians, It is adopted according to the purpose and application, such as technologies of various lighting devices, display devices, notification devices, and the like.

[0007]

As described above, it is possible to enhance the visibility of a road sign and to make a driver and surrounding pedestrians aware of the location at the time of traffic check and processing. Sign lighting and recognition lights,
Various notification techniques and means such as flashing lights such as red and yellow, tail lamps, and color cones are provided.

[0008] However, in combination with these lighting devices, light emitting devices such as recognition lights, blinking lights, tail lamps and the like, and the above-mentioned known and publicly disclosed technologies, all of the above-mentioned known embodiments disclose the radiated light from the light source to the target road sign. It is a method of directly emitting light or emitting light in the horizontal direction of the surroundings, and the light is emitted using a single light emitting means, but these are used in suburban areas where there are few other lights and lights. In addition, it exhibits the intended visibility and notification effect. However, in a city where there are many roads, shops, and businesses where traffic is frequent,
The visibility becomes extremely poor for the following reasons.

First, in a place where traffic is frequent, in a shopping district, or in a city with many buildings, etc., there are various lights such as red and yellow lights emitted from a number of traveling vehicles crossing each other. In addition, since various different things such as colors and patterns such as signboards and neon lights are added in the city, even if the important road sign is provided with the above-described sign dedicated lighting device, blinking light, color cone, etc. As described above, it becomes extremely inconspicuous when it is mixed with lights and colors in the city. As a result, the visibility of the intended road sign is reduced, resulting in drawbacks and inconvenience such that the intended purpose and effect cannot be exhibited.

[0010] For this reason, traffic accidents often occur due to the low visibility or oversight of road signs, and in the worst case, further accidents are called to the accident processing site. There is a demand for an effective and high-visibility lighting / lighting device, an alarm device, or the like that solves such problems and inconveniences. However, at present, no technology has been provided to meet the demand.

[0011]

The present invention solves the inconveniences and disadvantages of the prior art as described above, and effectively exerts not only means for recognizing road signs but also visibility at the time of traffic control and accident handling. The present invention provides a recognition sign light projecting device capable of performing the following. First, the light emitted from the lamp, which is the light source, is not directly illuminated on the target road sign, nor is it radiated and emitted in the surrounding horizontal direction from the processing site or the like. By radiating it on a road surface, wall surface, or the like close to a road sign or the like.

In addition, the light is projected not through a single light but through a certain slit hole or round hole, thereby enabling recognition marking in a striped or round dot pattern. The sign light projector has a basic configuration that includes a light shielding plate with a radiation hole provided with a plurality of narrow band-shaped slit holes or round holes in an opening of a case body containing a lamp or a reflection plate serving as a light source. The recognition sign light projecting device is configured.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A light projecting device according to the present invention is a general one in which a lamp 8 serving as a light source is located at the center of a reflection case 2 provided inside a case main body 1. Since a light shielding plate 14 provided with a plurality of strip-shaped radiating holes 13 is located in the opening, the light projecting device is mounted on a road sign A as shown in a usage example diagram of FIG. When the light is emitted after mounting, the light from the lamp 8 is
In the projection, the same streak pattern as that of the radiation hole 13 is enlarged, and the recognition sign pattern B is displayed on the road surface in a stripe pattern, that is, a black and white zebra pattern. An optical device 18.

Further, the ring edge 11 to which the light shielding plate 14 with the radiation hole 13 is combined has the slide groove hole 10 around it, so that the projected recognition mark is focused on depending on the inclination of the road surface or the position of the light emitting device. If not, the adjustment can be easily made by turning the ring edge 11 left or right. In addition, since the light-shielding plate 14 with the radiation holes 13 can be replaced, the recognition displayed on the road surface can be performed simply by replacing the light-shielding plate 14 with the radiation holes 13 having different shapes according to the application and purpose. Since the sign pattern B can be changed arbitrarily, the recognition sign light projecting device 18 that can meet various needs is made possible.

Therefore, when the floodlighting device according to the present invention is used for traffic-related equipment, not only high visibility of a road sign but also visibility of a traffic check and an accident processing site can be enhanced.
It is a simple and effective recognition and notification device, and since it is a notification device different from conventional lighting devices and notification devices, it has a highly original recognition that can exhibit its features even when used in combination with conventional technology. A sign light projecting device 18 is provided.
