Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle headlight, and more particularly to a headlight for a bicycle which enhances visibility from an oncoming vehicle at night.

[0002]

2. Description of the Related Art A bicycle headlight has a role of improving visibility at night from an oncoming vehicle or a vehicle traveling sideways, but since it disappears when the bicycle stops, it can perform its function. become unable. Therefore, conventionally, in order to improve the visibility at night even after the lights are turned off, for example, a reflective tape that reflects the light of an oncoming vehicle,
A reflector is provided.

However, since the visibility is limited only by reflecting the light of the oncoming vehicle in this way, a self-luminous function, for example, a light emitting device having an LED that lights for several tens of seconds after being turned off is provided. There is something like this. And
By providing such a light emitting device, it is possible to improve the visibility even when the bicycle is temporarily stopped and the headlight goes out at night.

[0004]

However, in such a conventional bicycle headlight, in order to turn on the LED of the light emitting device, for example, while a current from a generator attached to the bicycle is stored, There is a problem that the cost increases because a power supply device provided with a capacitor that supplies current to the LED after the light is turned off is required.

Therefore, the present invention has been made in order to solve the above problems, and an object thereof is to provide a bicycle headlamp which can improve the visibility at night at low cost. To do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view of a bicycle headlight according to an embodiment of the present invention, FIG. 2 is a front view thereof, and FIG. 3 is a cutaway side view thereof.

1, 2 and 3, reference numeral 1 is a bicycle headlamp main body (hereinafter referred to as main body), and 2 is a head case forming an outer surface of the main body 1. Here, a substantially circular opening 2a for illumination is formed on the front surface of the head case 2, and a lens portion 4 for diffusing the light from the light bulb 3 forward is formed in the center of the opening 2a. The translucent head cap 5 is attached. 1a is an arm for fixing the main body 1 to the bicycle.

Further, in this embodiment, an opening 2b for illuminating the side of the head case 2 for radiating the light from the electric bulb 3 to the side is formed as shown in FIG.
A so-called side eye 6 is formed by covering the opening 2b with a translucent side cap 6a, and the side eye 6 allows the light bulb 3 not only to an oncoming vehicle but also to a vehicle traveling laterally. It is possible to emit light from.

By the way, inside the head case 2, as shown in FIG. 3, a light bulb 3 is disposed in the center, and the light from the light bulb 3 is provided to face the lens portion of the head cap 5. A reflecting plate 7 for reflecting the light toward the light source 4 is provided. Then, as shown in FIG. 4, the reflector 7 has an opening 7 at a position corresponding to the side eye 6 of the head case 2.
a is formed, and a part of the light from the light bulb 3 passes through the side eye 6 and is radiated to the side by the opening 7a.

On the other hand, as shown in FIGS. 1 to 4, the light-retaining paint 8 is formed on the inner surface of the head cap 5 and the inner surface of the side eye 6.
Is applied, and the light-emission paint 8 constitutes a light-emitting portion that emits light at night. Further, by configuring the light emitting portion with the live light paint 8 as described above, the light emitting portion becomes less expensive than a conventional light emitting device that requires a power supply device. In the present embodiment, the light protection coating 8 on the inner surface of the head cap 5 is used.
Is applied to the lower position of the lens portion 4 and the back surface of the lens portion 4 having the best reflectance.

Here, the light-saving paint 8 is light from the outside such as sunlight, or the light bulb 3 that shines while traveling at night and is emitted forward or sideward as shown by the solid lines in FIGS. 3 and 4. This light is used for illuminating a part of the light, and the animal paint 8 can emit light by illuminating the light from the light bulb 3 or the like.

It should be noted that this light-saving paint 8 has a light-transmitting property so that it will not affect the emission of light even if it is applied to the back surface of the lens portion 4 or the inner surface of the side eye 6. . Also, this animal light coating 8 emits light at the same time as it is lighted, but since the amount of light storage is greater than the amount of light emission while the light bulb 3 is on, it continues to emit light even after the light bulb 3 is extinguished. Is able to.

Then, by applying the light-saving paint 8 to the back surface of the lens portion 4 of the head cap 5 to form a light emitting portion, after the bicycle stops and the light bulb 3 disappears,
The light from the live light paint 8 is reflected by the reflection plate 7 and is emitted forward as shown by the broken line in FIG. 3, so that the visibility from the oncoming vehicle can be improved even after the vehicle is stopped. ing. Further, by applying the livestock paint 8 to a position below the lens portion 4 so that light is also emitted from the lower portion of the head cap 5, the visibility from the oncoming vehicle can be further enhanced.

On the other hand, by applying the live light paint 8 to the inner surface of the side eye 6, after the bicycle stops and the light bulb 3 disappears, the light from the live light paint 8 is as shown by the broken line in FIG. Since it is radiated to the side, it is possible to increase the visibility from a vehicle traveling on the side even after the vehicle is stopped.

As described above, by providing the light emitting portion formed of the live light coating 8 on the inner surfaces of the head cap 5 and the side eyes 6, even after the bicycle is stopped,
Light can be emitted forward and sideward from this light emitting portion, and visibility at night can be enhanced.

In the above description, a case has been described in which the light-saving paint 8 is applied to the inner surfaces of the head cap 5 and the side eyes 6 so that the light-light paint 8 does not come into contact with the outside air. Depending on the shape of No. 1 and the like, the animal paint 8 may be applied only to the inner surface of the head cap 5 or to the inner surface of the side eye 6.

Further, the light-saving paint 8 is applied to the head cap 5
And when applying to the inner surface of the side eye 6, for example, as shown in FIG.
As shown in FIG. 5, by applying the animal paint 8 to the inner surface of the head cap 5 by silk printing in conformity with the shape of the lens portion 4, the design can be made excellent.

By the way, in the above description, the light emitting portions are formed on the inner surfaces of the head cap 5 and the side eyes 6 so that the animal paint 8 does not come into contact with the outside air, but the present invention is not limited to this. The light emitting portion may be provided on the outer surfaces of the head cap 5 and the side eyes 6 as long as it is possible to prevent the livestock paint 8 from contacting the outside air.

FIGS. 5 and 6 show the light emitting portions provided on the outer surfaces of the head cap 5 and the side eyes 6 as described above. In FIGS. 5 and 6, 9 indicates the outer surfaces of the head cap 5 and the side eyes 6. It is a transparent sheet to be attached (the one attached to the head cap 5 is not shown).
And between the side eye 6 and the side eye 6.

In the present embodiment, the light-duty paint 8 is applied to the back surface of the transparent sheet 9 so that the light-light paint 8 is present between the transparent sheet 9 and the head cap 5 and the side eyes 6 as described above. The transparent sheet 9 is attached to the outer surfaces of the head cap 5 and the side eyes 6 with a transparent adhesive.

[0030]

As described above, according to the present invention, it is possible to radiate light to the front and the side by the light emitting portion formed on the head cap and the side eyes, the light emitting portion being composed of the live light paint. The visibility can be improved. Further, by configuring the light emitting portion with the live-light paint in this way, the cost can be reduced as compared with a conventional light emitting device that requires a power supply device.
