Patent ID: 7709856

Claim:
A semiconductor light emitting device comprising: a support plate having a pair of longitudinal side surfaces, a pair of lateral side surfaces and a top surface, a plurality of wiring conductors disposed in parallel to each other adjacent to at least one of the longitudinal side surfaces of said support plate, a plurality of semiconductor light emitting elements mounted on the top surface of said support plate and electrically connected respectively to the wiring conductors, and a plastic encapsulant for sealing at least the longitudinal side surfaces and lateral side surfaces of said support plate, and each one end of said wiring conductors, wherein each of said wiring conductors has one end electrically connected to an electrode of said semiconductor light emitting element and the other end extending away from said support plate to out of said plastic encapsulant, said plastic encapsulant has at least one opening upwardly extending from a bottom surface of said plastic encapsulant and between said one of the longitudinal side surfaces of said support plate and an outer surface of said plastic encapsulant, said opening being formed along said one of the longitudinal side surfaces of said support plate to define a pocket of rectangular parallelepiped shape to expose a bottom surface of said wiring conductors to the outside of said plastic encapsulant, and said plastic encapsulant has a connection located in each gap defined between adjoining wiring conductors opened to said pocket.
