Abstract

The invention relates to a flexible printed circuit, an illumination apparatus, a capsule endoscope and a vehicle lighting apparatus. The flexible printed circuit for mounting a light emitting element has a base film, a wiring pattern formed on a surface of the base film, and a cover film that covers the base film and the wiring pattern. At least one of the base film and the cover film has a substrate comprising a metal. The cover film has such surface properties as to produce specular reflection or diffuse reflection of light or has a substantially white reflecting film on a surface of the cover film.

Description

technical field [0001] The present invention generally relates to a flexible printed circuit for mounting a light-emitting element, and a lighting device, a capsule endoscope, and a vehicle lighting device including the flexible printed circuit. More specifically, the present invention relates to a flexible printed circuit for mounting a light-emitting element, and a lighting device, a capsule endoscope, and a vehicle lighting device including the flexible printed circuit, wherein the flexible printed circuit enables emitting light such as a light-emitting diode (LED) The heat generated by the light-emitting element such as the light-emitting element and the light emitted by the light-emitting element can be efficiently used. Background technique [0002] A commonly used conventional flexible printed circuit (FPC) includes a base film and a predetermined wiring pattern formed on the surface of the base film. If necessary, the flexible printed circuit may further include a c...
