Lighting member using light-guiding film

A lighting member using a light-guiding film, the lighting member comprising:

• the light-guiding film which has a light incident part that is at least one of multiple side surfaces, and a light emergent part that is at least another one of the multiple side surfaces and faces the light incident part, at least a part of light incident on the light incident part being released from the light emergent part;
• multiple light-emitting diodes which are arranged at predetermined intervals in the vicinity of the light incident part so as to allow light to be incident on the light incident part;
• a mount board which is connected to the light-guiding film and has a surface on which the multiple light-emitting diodes are disposed;
• and
• a driving module which is connected to the mount board to electrically operate the multiple light-emitting diodes,
• wherein concave-convex portions are formed on a surface of the light emergent part to mitigate non-uniformity of a light emitting pattern on the light emergent part in a direction parallel to the light-guiding film which is caused as the multiple light-emitting diodes are disposed to be spaced apart from one another.

A lighting member using a light-guiding film, the lighting member comprising:

• the light-guiding film which has a shape defined by multiple cut surfaces formed by being cut and separated from a flexible light transmissive resin film, the light-guiding film having a light incident part that is at least one of the multiple cut surfaces, a light reflective part that is at least another one of the multiple cut surfaces and reflects light incident from the light incident part, and a light emergent part that is at least still another one of the multiple cut surfaces and faces the light incident part, at least a part of light incident on the light incident part and at least a part of light reflected from the light reflective part being released from the light emergent part;
• one or more light-emitting diodes which are disposed at predetermined positions in the vicinity of the light incident part so as to allow light to be incident on the light incident part;
• a mount board which is connected to the light-guiding film and has a surface on which the one or more light-emitting diodes are disposed;
• and
• a driving module which is connected to the mount board to electrically operate the one or more light-emitting diodes.

A method of manufacturing a lighting member using a light-guiding film, the method comprising:

• forming the light-guiding film which has a shape defined by multiple cut surfaces formed by being cut and separated from a flexible light transmissive resin film, the light-guiding film having a light incident part that is at least one of the multiple cut surfaces, and a light emergent part that is at least another one of the multiple cut surfaces and faces the light incident part, and at least a part of light incident on the light incident part being emergent from the light emergent part;
• aligning multiple light-emitting diodes at predetermined intervals on a mount board in the vicinity of the light incident part so as to allow light to be incident on the light incident part;
• and
• coupling the light-guiding film to the mount board which has a surface on which the multiple light-emitting diodes are disposed and to the driving module which electrically operates the multiple light-emitting diodes.
