Embodiment Construction
[0021] Embodiments are illustrated below with reference to the drawings. In addition, in each drawing, the same code|symbol is attached|subjected to the same component, and detailed description is abbreviate|omitted suitably.
[0022] (Lighting devices for vehicles)
[0023] First, the vehicle lighting device 1 according to the present embodiment will be described.
[0024] The vehicle lighting device 1 can be installed in, for example, an automobile, a rail vehicle, or the like. As the vehicle lighting device 1 installed in an automobile, for example, a front combination lamp (for example, a combination lamp that is appropriately combined with a daytime running lamp (DRL: Daytime Running Lamp), a position indicator light, a turn signal, etc.), can be used, for example. Rear combination lights (for example, brake lights, tail lights, turn signals, reversing lights, fog lights, etc., which are properly combined together), etc. However, the application of the vehicle lighting...

The invention provides a method for manufacturing a vehicle lighting device, the vehicle lighting device and a vehicle lamp, which can restrain high-thermal-conductivity resin with electrical conductivity from flowing out to the side of a power supply terminal even when a lamp holder and an insulating part provided with a plurality of power supply terminals are integrally formed. A method for manufacturing a lighting device for a vehicle according to an embodiment of the present invention comprises a step for integrally molding a lamp holder and an insulating part having insulativity and provided with a plurality of power supply terminals. In the step of integrated molding, a workpiece is placed in a die. When the insulating part is installed inside a first mold, the insulating part is insulated from the first mold. the end surface of the first mold is tightly attached to the end surface of one side of the insulating part; When the first mold and the second mold are assembled, the endface of the second mold and the end face of the other side of the insulating part are tightly attached together, and a cavity formed in the assembled first mold and second mold is filled with molten high-thermal-conductivity resin with electrical conductivity.
Description
technical field [0001] Embodiments of the present invention relate to a method of manufacturing a lighting device for a vehicle, a lighting device for a vehicle, and a lamp for a vehicle. Background technique [0002] A vehicle lighting device includes: a lamp holder; and a light emitting module provided on one end of the lamp holder and having a light emitting diode (LED: Light Emitting Diode). [0003] The heat generated when the light-emitting diode is lit is mainly released to the outside through the lamp holder. In addition, it is preferable that the lamp socket installed in the lighting device for a vehicle is lightweight. Therefore, lamp sockets containing high thermal conductivity resins have been proposed. [0004] However, conductive fillers such as carbon may be added to highly thermally conductive resins. Lamp sockets made of a highly thermally conductive resin to which a conductive filler is added may be conductive. If the conductive lamp holder comes into c...
