Abstract
A solid-state lamp comprises: one or more solid-state light emitting devices (typically LEDs); a thermally conductive body; at least one duct; and a photoluminescence wavelength conversion component remote to the one or more LEDs. The lamp is configured such that the duct extends through the photoluminescence wavelength conversion component and defines a pathway for thermal airflow through the thermally conductive body to thereby provide cooling of the body and the one or more LEDs.
