Abstract
An apparatus comprises a plurality of radiation conversion elements (32) that convert radiation to light, and a reflector layer (34) disposed around the plurality of radiation conversion elements. The plurality of radiation conversion elements may consist of two radiation conversion elements and the reflector layer is wrapped around the two radiation conversion elements with ends (40, 42) of the reflector layer tucked between the two radiation conversion elements. The reflector layer (34) may include a light reflective layer (50) having reflectance greater than 90% disposed adjacent to the radiation conversion elements when the reflector layer (34) is disposed around the plurality of radiation conversion elements, and a light barrier layer (52).
