LIGHTING DEVICES WITH DISCRETE LUMIPHOR-BEARING REGIONS ON REMOTE SURFACES THEREOF

摘要

A lighting device includes a semiconductor light emitting device (LED) configured to emit light having a first peak wavelength upon the application of a voltage thereto, an element in adjacent, spaced-apart relationship with the LED, and a pattern of discrete lumiphor-containing regions on a surface of, or within, the element. The lumiphor-containing regions are configured to receive light emitted by the LED and convert at least a portion of the received light to light having a longer wavelength than the first peak wavelength. The remote element may be a lens, a reflective element, or a combination thereof.
