Abstract
Disclosed is a lighting member that can be mounted to a structure having a complicated three-dimensional structure such as an automobile, so as to be used for the purpose of illumination, signaling, decoration, etc., the lighting member including a light-emitting diode and a light-guiding film. A lighting member using a light-guiding film according to an aspect of the present invention is morphologically defined by multiple cut surfaces which are formed by separated from a flexible light-permeable resin film by cutting. The lighting member includes a light-guiding film having a light incident part which is at least one of the multiple cut surfaces and a light-exiting part which faces the light incident part and is at least one of the multiple cut surfaces, the light-exiting part releasing at least a part of the light incident on the light incident part; a plurality of light-emitting diodes arranged at predetermined intervals of distance in proximity to the light incident part so as to make the incidence of light; a mounting substrate having the plurality of light-emitting diodes arranged on a surface thereof and connected to the light-guiding film; and a driving module connected to…
