Conventionally, a plate (hereinafter referred to as a "magic mirror") is known that has the property of mostly transmitting light projected from one surface and reflecting light projected from the opposite surface.

By the way, when it comes to bicycle headlights, the first
As shown in the figure and FIG. 2, the light from the illumination lamp 1 is reflected directly or by a reflecting mirror 2, and illuminates the front through a transparent lens 3 on the front side. Conventionally, this type of headlight has a headlight of an oncoming vehicle on both sides of the lens 3 of the bicycle headlight, in order to notify oncoming vehicles of the presence of a bicycle and to ensure the safety of the person riding the bicycle. Some are equipped with a reflector 5 that receives and reflects light. Therefore, the effective diameter W of the reflector 2 becomes smaller by an amount corresponding to the width of the reflector 5, and the irradiation area of the front surface becomes narrower, resulting in a disadvantage that the illumination effect of the headlamp as a whole is reduced.

This invention eliminates the drawbacks of the conventional method and covers the entire front illumination surface of the headlight with a magic mirror, so that the light from the headlight illuminates the front and the light from the oncoming vehicle is reflected. It is designed to inform you.

In one embodiment of the present invention, as shown in FIGS. 3 and 4, a magic mirror 6 is provided over the entire front surface of the case body 4 instead of the lens 3 and reflector 5 in FIGS. 1 and 2. . Here, the magic mirror 6 is the illumination light 1 on the back.
The front and back surfaces are selected and installed so that most of the light from the front is transmitted forward, and most of the light projected onto the front is reflected. As a result, the light from the oncoming vehicle is reflected by the magic mirror 6, making it possible to clearly recognize the headlights and the presence of the bicycle. Furthermore, since the irradiation surface is provided over the entire front surface of the case body 4, the area of the reflection surface of the reflector 2 can be expanded, and therefore the light from the illumination lamp 1 maintains its irradiation effect over a wide range. The magic mirror 6 can also be used as a mirror because it has almost total reflection.

As described above, according to the present invention, the entire irradiation surface of the headlight is covered with a magic mirror, so the light from the oncoming vehicle is reflected on the entire surface while maintaining a sufficient irradiation effect from the headlight. . Therefore, it is possible to provide a bicycle headlight that provides a sufficiently large illumination effect while having the function of ensuring the presence of a bicycle to be recognized by oncoming vehicles and ensuring the safety of the person handling the bicycle.
