Title:
METHOD FOR PRODUCING LAMP UNIT
Document Type and Number:
Japanese Patent JP2023096565
Kind Code:
A
Abstract:
To provide a lightweight and compact lamp unit particularly by shortening the time of a bonding process and extending the open time.SOLUTION: A method for producing a lamp unit includes a pre-bonding step for preparing a laminate in which a metal member (2), a solid binder (3) primarily composed of amorphous thermoplastic resin, which is at least one of thermoplastic epoxy resin and phenoxy resin, and a resin member (5) to be bonded to the metal member, are arranged in the stated order. The metal member is a heat sink. The resin member is a light source module having an LED device. The amorphous thermoplastic resin has an epoxy equivalent of 1,600 or more, or the amorphous thermoplastic resin is free of epoxy groups, with the amorphous thermoplastic resin having a heat of fusion of 15 J/g or less.SELECTED DRAWING: Figure 2
