  • Publication number: 20160010806
    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.

  • Publication number: 20150145406
    Abstract: A method is described for manufacturing an LED lamp module, where the individual LEDs in the lamp module do not include a conventional package structure and/or integrated encapsulation on the individual LEDs. The lamp module includes a co-extruded component, the co-extruded component comprising an elongate lens and a layer of photoluminescent material. The elongate lens is for shaping light emitted from the lamp and comprises an elongate interior cavity. The layer of a photoluminescent material is located on an interior wall of the elongate interior cavity. An optical medium is provided as part of the manufacturing process for the lamp module, where the optical medium surrounds the LEDs in an array of LEDs. The optical medium can be co-extruded over the LEDs. In addition, a liquid optical medium can be applied in the assembly process to remove air interfaces between the LEDs and component.
