Patent ID: 7605405

Claim:
A semiconductor light emitting device, comprising: a casing including, a first cavity that has a first bottom and is formed in a conical shape that opens upward from the first bottom, the first cavity having a first inner circumferential surface serving as a reflective surface, and a second cavity provided immediately above the first cavity, the second cavity including a second bottom having a flat surface, the second bottom being larger than the first cavity and forming a common plane with the first cavity, the second cavity having a substantially vertically upstanding inner circumferential surface, having a larger circumference than a circumference of the first cavity and being formed upward from the second bottom; a third cavity provided immediately above the second cavity, the third cavity including a third inner circumferential surface located on a substantially same extension from the first inner circumferential surface, the third inner circumferential surface serving as a second reflective surface; at least one semiconductor light emitting element located adjacent the first bottom of the first cavity; a first resin located in the first cavity to seal the at least one semiconductor light emitting element; and a second resin located in the second and third cavities, the second resin including a light-transmissive resin containing a wavelength converter dispersed therein.
