High power white LED lamp structure using unique phosphor application for LED lighting products

摘要

Phosphor application for high power LED lamps for use in lighting products includes a lensing structure and a phosphor layer applied to at least one side of the lensing structure. The lensing structure is positioned in the LED lamp so that emitted light from the LED die excites the phosphor layer. The lensing structure ensures both uniform color and light output as it eliminates the necessity of applying the phosphor layer directly to the LED die surface.
