Embodiment Construction
[0021] Hereinafter, embodiments will be illustrated with reference to the drawings. In addition, in each drawing, the same code|symbol is attached|subjected to the same component and a detailed description is abbreviate|omitted suitably.
[0022] (Lighting device for vehicle)
[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 such as a daytime running lamp (DRL: Daytime Running Lamp), a position light, a turn signal, etc., which is appropriately combined), Rear combination lamps (for example, combination lamps such as brake lamps, tail lamps, turn lamps, reversing lamps, fog lamps, etc., which are appropriately combined together), etc. However, the application of the vehicle light...

The present invention provides a method for manufacturing a lighting device for a vehicle, which can suppress the flow of a highly thermally conductive resin having electrical conductivity to the power supply terminal side even when a socket and an insulating portion provided with a plurality of power supply terminals are integrally molded, and a vehicle Lighting devices and lamps for vehicles. The manufacturing method of the vehicular lighting device which concerns on embodiment includes the process of integrally molding a socket and an insulating part which has insulating properties and is provided with a plurality of power supply terminals. In the step of integral molding, when the insulating portion is mounted inside the first mold, the end face of the first mold is brought into close contact with one end face of the insulating portion, and the first mold is placed in close contact with one end face of the insulating portion. When a mold and a second mold are combined, the end surface of the second mold and the other end surface of the insulating portion are brought into close contact with each other, and the first mold and the The cavity inside the second mold is filled with molten high thermal conductivity resin having electrical conductivity.
Description
technical field [0001] Embodiments of the present invention relate to a method of manufacturing a vehicle lighting device, a vehicle lighting device, and a vehicle lighting device. Background technique [0002] There is a vehicle lighting device including: a socket; and a light-emitting module provided on one end side of the socket 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 socket provided in the vehicle lighting device be lightweight. Therefore, sockets containing high thermal conductivity resins have been proposed. [0004] However, a conductive filler such as carbon may be added to the highly thermally conductive resin. A lamp holder containing a highly thermally conductive resin to which a filler having electrical conductivity is added may have electrical conductivity. When the conductiv...
