Problems solved by technology

Therefore, in the existing lamps, the formation process of the light reflection film is particularly complicated, which is the main reason for the high cost.
In addition, even in the case of forming a light reflection film with a mask, the paint or deposited film will enter from the gap between the mask and the reflector and adhere to the surface of the welded leg of the reflector, and proper melting cannot be performed. apply
On the other hand, as the above-mentioned light reflection film, although there is also the case of forming an aluminum film by electroplating, in this case, since a mask such as a protective film is formed on the front end surface of the welding leg of the reflector, After the electroplating process, the process of peeling off the protective film is necessary, which complicates the process of forming the surface treatment film, which is also the main reason for the high manufacturing cost.

Embodiment Construction

[0015] Embodiments of the present invention will be described below with reference to the drawings. figure 1 It is a partial sectional perspective view showing an embodiment of a composite lamp CL which applies the present invention to an automobile tail lamp and a rear combination lamp which integrates a tail lamp, a parking lamp, a reverse lamp, and a turn signal lamp here, figure 2 is its longitudinal section. The above-mentioned composite lamp CL divides the inside of the lamp body 1 integrally molded with thermoplastic resin into four lamp chambers 2a-2d by means of the partition wall 1a, and at the same time installs bulbs in each lamp chamber 2a-2d through the bulb sockets 4a-4d, respectively. 3a to 3d constitute the above-mentioned tail light and stop light T&SL, back light BUL, and turn signal light TSL, respectively. Among them, the lamp body 1 is divided into upper, middle and lower sections, and taillights and parking lights T&SL are arranged in the upper and lo...

Abstract

A vehicle lamp fixture comprising a reflector that is made of a thermoplastic resin and is covered with a light reflecting film on its surface and a lens that is made of a thermoplastic resin and is mounted on the reflector. The reflector has a welding leg portion which projects from the circumferential edge of the reflector, and the tip end of the reflector welding leg portion is formed with an inclined surface which is inclined with respect to a direction in which the lens is brought to make a contact with the reflector when welding is performed between the reflector and the lens.

Description

technical field [0001] The present invention relates to a vehicular lamp suitable for use in automobiles, and more particularly to a vehicular lamp in which a lens is fixed by welding. light reflective surface. Background technique [0002] In vehicle lamps, in order to simplify the structure and improve the liquid tightness inside the lamp, it is mounted on the front of the lamp body and the reflector (hereinafter referred to as the reflector including the lamp body) with a light reflecting surface. The lens on the opening is formed by thermally welding the edge of the opening of the reflecting mirror. Figure 7 is a schematic cross-sectional view representing such an example, such as Figure 7 As shown in (a), the reflection mirror 101 is formed of thermoplastic resin, and a reflection mirror welding leg 106 with a convex cross-sectional shape protruding forward is formed on the opening edge thereof. In addition, a light reflection film 105 is fo...
