Abstract

PROBLEM TO BE SOLVED: To form a lighting fixture without interposing a reflector for mounting a light source bulb, as required according to the conventional arrangement, despite this configuration where a front face lens is jointed directly with the lamp body. SOLUTION: A lamp body 14 is formed from a heat-resistant resin material, and a light souce bulb 12 is fitted in the lamp body 14. Joining of a front face lens 16 with the lamp body 14 is generated by laser welding. Because of the lamp body material as heat-resistant resin, no thermal deformation will be made even if it is heated by the heat emitted when the bulb 12 is lighted up. This eliminates necessity for interposing of any reflector for mounting of light source bulb as conventional. Owing to laser welding, joining of the two members 16 and 14 can be made without any problem despite the heat-resistant resin material of lamp body 14, and it is practicable to secure sufficient joining strength.

Conventionally, the joining method includes an indirect joining method using a sealing material. Direct joining is known in which a front lens and a lamp body are brought into direct contact with each other and joined. Hot melt sealing and the like are known as specific methods of indirect bonding, and hot plate welding, vibration welding and ultrasonic welding are known as specific methods of direct bonding.

The cost for the seal material is extra, and it is necessary to form a relatively large groove to apply the seal material. In addition, a decorative treatment for making the seal material in this groove hard to be seen from the outside of the lamp is required. Required.

ルブ挿着部が熱変形してしまうこととなる。That is, when the front lens and the lamp body are joined by hot plate welding, vibration welding or ultrasonic welding, if a heat resistant resin material such as PC (polycarbonate) is used as the material of the lamp body, the welding is performed. Therefore, the lamp body cannot be made of a heat-resistant resin material because the lamp body deteriorates and the amount of burrs increases. For this reason,
When the light source bulb is directly inserted into the lamp body, heat generated by the lighting of the light source bulb causes the light source bulb insertion portion of the lamp body to be thermally deformed.

It can be welded to the member. Therefore, in the present invention, by employing laser welding as a joining means between the front lens and the lamp body, even though the lamp body, which is a laser light opaque member, is formed of a heat resistant resin material, there is no problem. Both can be joined without hindrance, and thereby sufficient joining strength can be ensured. Further, in the vehicular marker lamp according to the present invention, the light source bulb is inserted into the lamp body, and the lamp body is heated by the heat generated by the lighting of the light source bulb, but the heating temperature is lower than 115 ° C.

Therefore, it is preferable that the wavelength of the laser beam used for laser welding is also set according to the light transmittance characteristics of the front lens. However, since the oscillation wavelength of a YAG laser or the like is fixed, it is not possible to obtain a laser beam in a wavelength region having an excellent light transmittance.
On the other hand, in a semiconductor laser, the oscillation wavelength can be changed depending on the oscillation conditions instead of the single oscillation wavelength. By appropriately adjusting the oscillation band, the light transmittance can be adjusted according to the material of the front lens. Laser light in a wavelength region excellent in temperature.
