Embodiment Construction

[0030] Hereinafter, the best mode for implementing the vehicle lamp and its manufacturing method according to the present invention will be described with reference to the drawings.

[0031] refer to figure 1 The outline of the vehicle lamp according to the present invention will be described.

[0032] The vehicle lamp 10 has a lamp body 20 in which three recesses 21 , 22 , and 23 opening forward are formed. In addition, light source bulbs 31 , 32 , 33 are disposed in the recesses 21 , 22 , 23 .

[0033] A light distribution mirror 40 is configured to cover the front of the lamp body 20 and is divided into three lamp chambers 51 , 52 , 53 . Such as figure 1 and Figure 4 As can be seen from the illustration, the light distribution mirror 40 is formed by integrally forming three plastic molding parts 41 , 42 , 43 . The plastic molded part 41 is made of red plastic, the plastic molded part 42 is made of colorless plastic, and the plastic molded part 43 is made of amber plas...

Abstract

The invention relates to a vehicle-used lighting and a manufacturing method, enabling colors of plastics forming parts earlier cast not to be mixed in the plastics forming parts later cast. The vehicle-used lighting (10) is provided with a matched mirror (40); plastics forming parts (41), (42), and (43) with more than two colors are integrated to form the matched mirror (40); injection molding process is adopted in forming the matched mirror; the molecular weight of the injected plastics from the plastics forming parts (42) after the formation of the matched mirror is smaller than that of earlier injected plastics from the first plastics forming parts (41) and (43) before the formation of the matched mirror.

Description

technical field [0001] The present invention relates to a new vehicle lamp and its manufacturing method. Specifically, it relates to preventing the plastic part of one color from being mixed into the vehicle peripheral lamp having a light distribution mirror formed by integrally forming more than two-color plastic molding parts. Another colored plastic part of the technology. Background technique [0002] A lamp for a vehicle has a photodistribution lens formed by integrally forming two-color or more plastic molded parts. Plastic light distribution mirrors are often used in the light distribution mirrors of vehicle lamps, especially in signal lamps, which use the so-called multi-color molding method to integrally form multiple plastic parts of different colors. In the manufacture of multifunctional signal lamps with different functions, the forming process of the optical mirror is simplified, and the management of parts is simplified at the same time, which is beneficial to...
