OPTICAL ELEMENT EDGE TREATMENT FOR LIGHTING DEVICE |
摘要 |
A lighting device includes an electrically activated emitter, a lumiphoric material spatially segregated from the emitter, and an optical element arranged between the emitter and the lumiphoric material and having at least one peripheral edge, wherein a reflective material is disposed proximate to the at least one peripheral edge and/or wherein the at least one peripheral edge is non- perpendicular to a face of the optical element and arranged to reflect light in a direction toward the lumiphoric material. An optical element for use with a lighting device including a lumiphoric material includes a peripheral edge, wherein a reflective material disposed substantially parallel to the peripheral edge and/or wherein the peripheral edge is non-perpendicular to a face of the optical element and arranged to reflect light in a direction toward the lumiphoric material. |
