Abstract
A solid-state lamp is described that includes a wavelength conversion component located at one end of the lamp. The 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, located at one end of the lamp. 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.
