摘要
An illumination module includes a plurality of Light Emitting Diodes (LEDs) and a light conversion sub-assembly mounted near but physically separated from the LEDs. The light conversion sub-assembly includes at least a portion that is a polytetrafluoroethylene (PTFE) material that also includes a wavelength converting material. Despite being less reflective than other materials that may be used in the light conversion sub-assembly, the PTFE material unexpectedly produces an increase in luminous output, compared to other more reflective materials, when the PTFE material includes a wavelength converting material.
