Abstract

PROBLEM TO BE SOLVED: To perform the self-emission of light and ensure the recognition of a body by providing a surface light emitting body on the side surface of the body, and supplying power to the surface light emitting body from a power source to emit a light. SOLUTION: A surface light emitting body 6 provided on the side surface of a body receives the supply of a power from a power source 8 built in a generating lamp 7 corresponding to a headlamp of bicycle and makes a display part 9 emit a light with a fixed brightness. Namely, when the circumference dark begins to darken, an optical sensor circuit 10 is operated, and the generation of a generator 15 charges a battery 12 through a charging circuit 11. On the other hand, the power of this battery 12 is supplied to the surface light emitting body 6 through an amplifying circuit 13 and an inverter circuit 14 by the operation of the optical sensor circuit 10 to make the display part 9 of the surface light emitting body 6 emit a light. Thus, a body can be confirmed from the circumference under any state of running and stopping, and the visual confirmability can be remarkably enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luminous safety device for a bicycle or the like used for a bicycle, a three-wheeled vehicle, an electric two-wheeled vehicle, a three-wheeled vehicle, etc., and capable of clearly recognizing the presence of a vehicle body during running or the like.

[0002]

2. Description of the Related Art A conventional luminous safety device of this type is provided with a reflective tape, a reflector or the like coated with luminous paint or the like on the side surface of a bicycle body, and emits or reflects light from another light source. Met.

[0003]

However, in the above-mentioned conventional configuration, the light of head lamps of other bicycles, automobiles and the like is reflected and emitted, thereby notifying the existence of one's own bicycle or the like. Depending on the angle and strength of the vehicle, the function could not be fully exhibited, and the safety of night driving was insufficient.

In particular, in recent years, the use of bicycles at dusk or at night has increased due to the attendance of schoolchildren and extracurricular activities, and traffic accidents have been increasing accordingly. It is becoming more important.

An object of the present invention is to solve such a conventional problem, and an object of the present invention is to provide a light-emitting safety device which emits light by itself and ensures recognition of a vehicle body.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to provide a surface illuminator on a side surface of a vehicle body and supply power from a power source to the surface illuminator to emit light.
Since the surface light emitter emits light by the power supply, the function of recognizing the presence of the vehicle body can be sufficiently exhibited.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to solve the above problems, the present invention comprises a surface light emitter provided on a side surface of a vehicle body, and a power supply for supplying power to the surface light emitter to emit light.

Further, the present invention comprises a surface light emitter provided on a side surface of a vehicle body, and a power supply having a sensor function of automatically supplying electric power to the surface light emitter when necessary to emit light.

As described above, since the surface luminous body itself emits light when supplied with electric power, it emits light at a constant brightness without being influenced by the incident angle and intensity of light from a light source of another bicycle, automobile, or the like. It will surely inform the presence of the vehicle body.

Since the surface illuminant is automatically supplied with power from the power supply when necessary by the sensor function, the light emitting operation is not forgotten and the light is reliably emitted.

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a bicycle body having a frame 2, a saddle 3, a fork 5 supporting a front wheel 4, and the like. Reference numeral 6 denotes a flexible and thin planar light-emitting body which is attached to the frame 2 with an adhesive or the like. The surface light emitter 6 is provided with a power supply 8 built in a power generation lamp 7 corresponding to a headlight of a bicycle.
The display unit 9 emits light at a constant brightness upon receiving power supply from the display unit 9. The power source 8 of the surface light emitter 6 includes an optical sensor circuit 10, a charging circuit 11, a battery 12 such as a NiCd battery charged by the charging circuit, and an amplifier circuit 1 for increasing the voltage of the battery.

5 is connected. The power generation lamp 7 containing the power supply 8 is connected to the generator 15 via the optical sensor circuit 10.
Main sphere 16 and battery 12 illuminated by being supplied with power from
It has a sub-beam sphere 17 which is supplied with electric power through the optical sensor circuit 10 and lights up. The generator 15 is incorporated in the hub 4 a of the front wheel 4 and generates electric power by rotation of the front wheel 4. The light sensor circuit 10 automatically operates when the ambient illuminance lowers below a certain level of brightness, and operates the generator 15 to generate electricity from the main sphere 16 and the power supply 8 of the surface light emitter 6.
1.

In the above embodiment, the light sensor circuit 10 operates when the surroundings start to darken while the bicycle is running. Then, the power generation of the generator 15 charges the battery 12 via the charging circuit 11. On the other hand, the power of the battery 12 is supplied to the surface light emitter 6 via the amplifier circuit 13 and the inverter circuit 14 by the operation of the optical sensor circuit 10, and the display unit 9 of the surface light emitter 6 emits light. Therefore, the running vehicle 1
Can be reliably recognized from the side. Further, even when the running of the vehicle body 1 is stopped, the surface light emitter 6 emits light by being supplied with power from the battery 12, so that the stop of the vehicle can be recognized. In particular, when the bicycle is placed in a bicycle parking lot at night, if the surface illuminator 6 having the display unit 9 that can be distinguished from other bicycles is used, it is possible to easily find one's own bicycle from among many bicycles. .

As described above, according to the present invention, the surface light emitter is provided on the side surface of the vehicle body, and the surface light emitter is supplied with electric power from the power supply to emit light. It emits light, and the vehicle body can be recognized from the surroundings in any state of running or stopping, so that visibility can be dramatically improved and safety can be further secured.

Further, according to the present invention, since the surface light-emitting body automatically emits light when supplied with electric power when necessary, the light-emitting operation of the vehicle body is not forgotten and the safety by reliable light-emitting can be ensured.
