Description

[Detailed description of the invention] This invention relates to bicycle headlights, especially those with colored translucent front lids, so that the coloring will not fade or peel off, and the coloring will last for a long time. It relates to items that are kept in good condition and that do not reduce the product value.

Conventionally, in this type of bicycle headlamp, coloring was applied from the outside to a convex portion or a concave portion provided for coloring on the outside of the translucent front cover.

However, in such conventional examples, sunlight, rain, etc.
The durability of the colored portions was problematic because the colored portions were directly affected by changes in the external environment, or the colors faded or peeled off due to wear and the like.

The present invention improves the above-mentioned drawbacks by providing this colored portion inside the headlamp housing.

Hereinafter, the bicycle headlamp of the present invention will be explained according to the embodiment shown in the drawings. 1 is a rear case 3 with a front opening having a bicycle mounting ear piece 2, and a case 3 made of translucent synthetic resin that closes this front opening. A headlight housing consisting of a translucent front cover 4, this housing 1
A light bulb 5 and a reflector 6 are housed inside.

The light-transmitting front cover 4 has a light-emitting lens 7 and a light-emitting lens frame 8. The light-transmitting front cover 4 has a peripheral edge of the reflecting mirror 6 on the inner surface of the light-transmitting front cover 4 around the light-emitting lens 7. A protruding part 9 to be inserted is protruded around the circumference, and the end face of the protruding part 9 is colored by applying orange paint to form a colored part 10.

By curving the outer surface of the transparent front lid 4 facing the colored portion 10 between the light emitting lens 7 and the light emitting lens frame 8 into a U-shaped cross section, the coloring from the colored portion 10 is removed. A magnifying lens section 11 is provided to magnify the light.

Further, FIG. 4 shows another embodiment of the present invention, in which reference numeral 11' denotes a U-shaped magnifying lens portion protruding circumferentially from the outer surface of the translucent front cover 4 facing the colored portion 10.

FIG. 5 shows still another embodiment of the present invention. In the same figure, reference numeral 12 denotes a concave portion provided circumferentially on the inner surface of the translucent front lid 4, and by applying orange paint to this inner surface, the colored portion can be colored. 1
0', and a U-shaped magnifying lens part 11' is provided around the outer surface of the translucent front cover 4 facing the colored part 10'.

The bicycle headlight of the present invention is constructed as described above, and in particular, a part of the inner surface of the translucent front lid is colored to form the colored part, so that the colored surface does not come into direct contact with the external environment and is not directly exposed to the outside. Since there is no contact, the coloring will not fade or peel off, and therefore the colored state can be maintained beautifully for a long period of time, and the product value will not decrease over a long period of time. Since a magnifying lens part is provided on the outer surface of the translucent front cover facing the colored part, the width of the colored part can be seen enlarged to the width of the magnifying lens part, and therefore a large display can be achieved with a small colored area. You can get the effect,
Therefore, it is possible to obtain a highly effective display.
