Description

[Detailed explanation of the invention] This invention relates to vehicle lights such as bicycle headlights.
In particular, the present invention relates to a lamp that uses a mirror-treated film sheet material as a reflecting mirror, and houses and installs the reflecting mirror within the main body of the lamp while reinforcing the reflecting mirror.

Conventionally, these types of vehicle lights have used reflectors made of metal plates or synthetic resin reflectors with mirror-treated reflective surfaces, but in these conventional examples, individual reflectors are made of vacuum-deposited aluminum, for example. A mirror treatment is required, and a pretreatment process such as degreasing is required before the mirror treatment. Therefore, by forming the reflecting mirror from a film sheet material that has been mirror-treated in advance, the mirror-finishing step and pre-treatment step can be omitted, but in this case, the strength of the reflecting mirror itself is weak and some kind of reinforcing member is required. This project reduces the number of parts used by using the rear case as a reinforcing member, and by attaching a light bulb socket to the rear case itself, it is possible to replace the light bulb without disassembling the lamp, and the overall structure is compact. This is a summary of the following.

Hereinafter, the present invention will be explained based on the embodiment shown in the drawings. Reference numeral 1 denotes a transparent front cover made of synthetic resin, which has a lens part 2 and a cylindrical lens frame 3. Below 3 is a piece 4 for attaching it to the vehicle.
are integrally molded.

Reference numeral 5 indicates a light bulb, and reference numeral 6 indicates a sheet reflector that reflects the light from the light bulb.The reflector 6 is made of a mirror-treated film sheet, such as an aluminum-deposited polyethylene film sheet, and is formed into a parabolic shape by, for example, press thermoforming. It is formed by molding it into a shape.

Reference numeral 7 denotes a rear case that is fitted into and fixed to the translucent front cover 2 from behind the cylindrical lens frame 3. The rear case 7 has an opening 8 in the center for inserting a light bulb, and its inner surface is made of the reflective sheet. A reinforcing surface 9 is formed in the shape of a paraboloid along the back surface of the mirror 6. With the sheet reflecting mirror 6 in contact with this reinforcing surface 9, the outer periphery 10 of the sheet reflecting mirror 6 is held in between. It is adapted to abut and lock onto the periphery of the lens portion 2 of the translucent front cover 1.

Reference numeral 11 designates a light bulb socket into which the light bulb 5 is inserted into and out of the aperture 8; the circumferential terminal 5a of the light bulb 5 is fitted and fixed into the recess 12 of the light bulb socket;
It is inserted from the rear.

13 is a ground lead wire whose one end is held between the peripheral terminal 5a of the light bulb 5 and the inner wall of the recess 12;
The other end has a ground lug plate 14, and by exposing and attaching this lug plate 14 to the surface of the attachment piece 4, the attachment piece 4 is grounded at the same time as it is attached to the vehicle. .

15 is a terminal fitting 1 attached to the tail terminal 5b of the light bulb 5.
6, and the other end is connected to a power supply part of a bicycle generator (not shown).

The vehicle lamp of the present invention is constructed as described above, and has a sheet reflector made of a mirror-treated film sheet, an opening in the center for inserting a light bulb, and the sheet reflector is brought into contact with the inner surface of the sheet. A rear case that protects the reflector; the periphery of the rear case is fitted onto the periphery of the lens part to sandwich the periphery of the reflector between the rear case periphery and the lens part periphery; Since it has an integrated front cover and a light bulb socket for attaching a light bulb and inserting the light bulb in and out from the opening, the sheet reflector is directly reinforced on the inner surface of the rear case. A mirror with a uniform mirror surface state and good reflection efficiency can be obtained at low cost without the need for a special reinforcing member.

Furthermore, according to the present invention, the periphery of the sheet reflector is clamped and fixed at the same time when the periphery of the lens portion of the front cover and the periphery of the rear case are fitted together, so the assembly work can be simplified, and the front cover, rear case, and reflector plate There is no need for parts to fix the lens, reducing the number of parts.In addition, the periphery of the sheet reflector has a sealing effect as a sealing material, preventing rainwater from entering between the periphery of the lens part and the periphery of the rear case. Furthermore, the light bulb can be replaced by simply removing the light bulb socket from the light bulb insertion hole in the rear case, greatly simplifying the task of replacing light bulbs. .
