摘要：
An ophthalmic endoilluminator is provided. The ophthalmic endoilluminator includes one or more white light emitting diodes (LEDs), an additional light source, a first optical assembly, an optical coupling element, and an optical fiber optically coupled to the optical coupling element. The white LED is capped with a phosphor layer. The additional light source illuminates at least a portion of an exterior surface of the phosphor layer within an absorption band of phosphor material of the phosphor layer in order to excite the phosphor layer and produce additional white light. The first optical assembly receives and substantially collimates the white light. The optical coupling element receives the substantially collimated white light from the first optical assembly and directs the light to an optical fiber. The optical fiber is then used to conduct the white light into an eye.
