Abstract:
1. An LED module comprising: a flexible wiring substrate being provided at its surface with a plurality of power supply terminals, said flexible wiring substrate being provided with a patterned wiring, each of said power supply terminals comprising a first electrode pad and a second electrode pad, each of said power supply terminals being electrically connected to said patterned wiring, a plurality of surface mounting type LED packages which are mounted on said flexible wiring substrate, each of said surface mounting type LED chip comprising an LED chip and a mounting substrate, each of said mounting substrate being formed at its front surface with a recess, and being formed at its rear surface with an external connection electrode, said external connection electrode comprising a first connection electrode and a second connection electrode, each of said mounting substrate being mounted on said flexible wiring substrate such that said first connection electrode and said second connection electrode are electrically connected to said first electrode pad and said second electrode pad, respectively, said LED chip being disposed within said recess, said LED chip being configured to receive electrical current through said external connection electrode and said power supply terminal, and said LED module being formed by cutting an LED module wafer, said LED module wafer comprising an LED package wafer and a flexible wiring wafer, said LED package wafer comprising a plurality of said surface mounting type LED packages, said flexible wiring wafer being formed into said flexible wiring substrate when said flexible wiring wafer is cut, said flexible wiring wafer being directly coupled to said LED package wafer such that each of said patterned wiring being connected to each of said external connection electrode, said LED package wafer being formed with a groove which reaches a top surface of said flexible wiring substrate, and said groove surrounding each of said surface mounting type LED package so that said surface mounting type LED package is spaced from adjacent said surface mounting type LED package.
