[Industrial applications]

 The present invention relates to an indicator light installed on a pavement of a road or an edge line of a road shoulder, and more specifically, to clearly indicate a boundary such as a roadway, a sidewalk, and a lane, and an inaccessible area. The present invention relates to a self-luminous warning indicator light that is installed and emits light, and is used as a warning to ensure the safety of vehicles and pedestrians especially at night.

[0002]

[Prior art]

 Conventionally, this type of light-emitting indicator lamp uses a light-emitting diode as a light source, and uses a storage battery charged by a solar battery as a power source to emit the light-emitting diode at night. It is already well known.

For example, to show an example of the structure of a conventional light emitting indicator lamp, in order to facilitate visual recognition of light from the diode, the light emitting diode is housed inside the case, and the side surface of the case is inclined, The one that is installed so that the side surface projects from the road surface is listed.

However, according to the configuration of the conventional light-emitting display lamp of this kind, since the case needs to be installed so as to protrude from the road surface, when the vehicle passes through the upper surface, the tire rides on the upper surface portion. However, there is a problem that it causes a dangerous situation, and the risk is particularly great in the case of rainfall.

Further, in the conventional light emitting type display lamp of this kind, since the light emitting diode which consumes less power is used, the light emitting amount is small and the visual recognition cannot be performed from a long distance. In order to do so, there was a new problem that the structure became complicated.

Therefore, in recent years, in order to eliminate the above-mentioned conventional drawbacks, as shown in FIGS. 1 and 2, a solar cell 103 is arranged in the center of the inside of a case 101 whose surface is closed by a transparent glass plate 102. At the same time, the storage battery 4 charged by the solar cell 103, a plurality of light emitting diodes 106 that are turned on by using the storage battery 104 as a power source, and light from the light emitting diodes 106 are directed to above the transparent glass plate 2. A road light emitting sign device having a structure (Japanese Patent Laid-Open No. 4-34105) in which a dodge reflector 105 is housed inside the case 101 has been developed.

However, in the structure of the road marking device for road, the tire is mounted on the upper surface portion when the vehicle passes through the upper surface because the road light emitting sign device is configured so as not to project to the surface of the road. However, the structure becomes complicated and large-scaled, and the amount of light emitted from the light emitting diode is still small, and the drawback that visual recognition from a distance is not possible remains. To do.

In order to increase the amount of light emitted from the light emitting diode, as shown in FIGS. 3 and 4, a plate-shaped reflector 202 that is inclined at an angle α with the ground surface 207 is fixed, An elliptical hole 203 is formed in a part of the reflector 202, and a center line 206 at the back of the reflector 202 forms an angle β with the reflector 202 (where β 2> α) and is transparent so as to incline slightly backward. The quadric body 4 is provided, and the entire end surface 205 of the quadric body 204 is matched with the elliptical hole 203 so that the surface of the reflector 202 and the front end surface are flush with each other. A light emitting diode 209 is provided at a focus position in the curved body 204, and a metal film 208 is provided on the outer peripheral paraboloid of the quadric body 4 (see Japanese Patent Publication No. -3620 No. 6 There has been developed.

However, even in the above-mentioned surface-mounted tack type road signaling device, since it is composed of the reflector and the quadric surface body, it has a relatively simple structure. Although a convex lens is provided on the front surface of the part to improve the directivity of light emission, it is said that the width of the directional distribution becomes narrower than that of the high brightness one, especially in the case of ultra-high brightness one. In order to ensure the emission efficiency of the light from the condenser lens at the tip of the light emitting diode to the rear, it is necessary to provide an elliptical or cylindrical hole integrally with the reflector to ensure the emission efficiency. However, the current situation is that there are many ineffective rays and highly efficient emission cannot be obtained.

[0010]

[Problems to be solved by the device]

 The present invention has been made in view of the above circumstances, and it is possible to expand the directivity of the light emitting diode and the size of the light source without disturbing the light source of the light emitting diode, and to use it for other than the road surface. The purpose of the invention is to provide a self-luminous warning indicator lamp that enables clear emission display at a distant position.

[0011]

[Means to be solved by the device]

 The self-luminous warning indicator light of the present invention is a case formed of a trapezoidal shape, an upper case made of aluminum die cast with a solar cell arranged on the upper surface, and a lower case integrally fitted with the upper case. In a self-issued warning indicator light in which a battery to be charged by the solar cell and a control circuit board are installed inside the main body, and a light emitting diode and a reflector are arranged on the side surface of the case body, a cone with aluminum vapor-deposited on the outer circumference is used. A cylindrical body is provided around the light emitting diode, an opening end surface of the conical cylindrical body is fitted to a reflector on the side surface of the case body, and a convex lens is fitted to the opening surface portion on the reflector fitting side, and It is also characterized in that a triangular prism is arranged on the outer periphery of the reflector fitting portion so that the emission efficiency and light collection of the light emitting diode can be expanded as much as possible. It is.

[0012]

[Function of the device]

That is, in the self-luminous warning indicator lamp of the present invention, a cone-shaped cylindrical body having aluminum vapor-deposited on the outer periphery is provided around the light emitting diode, and a convex lens is attached to the reflector at the opening end surface of the cone-shaped cylindrical body. Therefore, the light emitted from the light emitting diode can be expanded and emitted by the aluminum portion on the outer periphery, and the expanded and emitted light is condensed by the convex lens and emitted to the front, so that the light emission with high efficiency and strong directivity can be obtained. can get.

Further, in the self-luminous warning indicator lamp of the present invention, the conical cylindrical body and the reflector can be integrally formed, and further, these and the convex lens can be easily integrally formed. Therefore, by integrally forming the structure, it is not necessary to adjust the inclination angle of the light emitting diode, the conical cylinder, and the reflector, and the assembling work can be simplified and the working cost and the manufacturing cost can be reduced. I can do things.
