Abstract

A solid-state lamp is described that includes a first light emission zone and a second light emission zone, where the first light emission zone is longitudinally spaced apart from the second light emission zone. The light emission zones comprise a photoluminescence wavelength conversion component and a solid state light emitting device. The lamp comprises a lower body, a central body, and an upper duct, where the central body, and the upper duct together define at least one passage way/duct for thermal airflow.
