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.
Claims16
A lamp, comprising:
- a plurality of solid-state light emitting devices, the plurality of solid-state light emitting devices arranged with an emission axis parallel to an axis of the lamp;
- a thermally conductive body;
- at least one duct;
- and
- a photoluminescence wavelength conversion component to receive excitation light from the plurality of solid state light emitting devices, wherein the at least one duct comprises a first opening and a second opening, and wherein the at least one duct extends through the photoluminescence wavelength conversion component from the first opening to the second opening such that in operation air from external to the lamp flows through the first opening into and through the at least one duct to exit the lamp through the second opening.
