Method of manufacturing annular oblique light illumination apparatus and flexible wiring substrate

Abstract

A flexible wiring substrate forms a light emitting device array attached to a frustoconical inner circumferential surface that serves as a light emitting device arranging surface of an annual oblique light illumination apparatus. A plurality of arcuate zonal wiring patterns for mounting light emitting devices are provided. Each wiring pattern is in the form of a developed frustoconical shape. The wiring patterns are serpiginously provided continuously directly or by way of connecting wiring patterns to a base film of a predetermined shape.

1 . A flexible wiring substrate for forming a light emitting device array attached to a frustoconical inner circumferential surface serving as a light emitting device arranging surface of an annular oblique light illumination apparatus, wherein 
 a plurality of arcuate zonal wiring patterns for mounting light emitting devices each in the form of a developed frustoconical shape are serpiginously provided continuously directly or by way of connecting wiring patterns to a base film of a predetermined shape.    
   
   
       2 . A flexible wiring substrate for forming a light emitting device array attached to a frustoconical inner circumferential surface serving as a light emitting device arranging surface of an annular oblique light illumination apparatus, wherein 
 one or more annular zonal wiring patterns for mounting light emitting devices each in the form of a developed frustoconical shape when cut at a predetermined center angle are provided on a base film of a predetermined shape.    
   
   
       3 . A flexible wiring substrate for forming a light emitting device array attached to a frustoconical inner circumferential surface serving as a light emitting device arranging surface of an annular oblique light illumination apparatus, wherein 
 one or more arcuate zonal wiring patterns each corresponding to a developed frustoconical shape are provided to a base film of a predetermined shape.    
   
   
       4 . A flexible wiring substrate according to  claim 1 , wherein the base film of the predetermined shape has a substantially square shape.  
   
   
       5 . A flexible wiring substrate according to  claim 2 , wherein the base film of the predetermined shape has a substantially square shape.  
   
   
       6 . A flexible wiring substrate according to  claim 3 , wherein the base film of the predetermined shape has a substantially square shape.
