| 摘要 |
This invention discloses a lighting device for providing an illumination with enhanced color uniformity. The lighting device includes a light generating element adjacent a substrate and configured to produce light having wavelengths substantially within a first wavelength range; a transparent frame attached to the substrate, surrounding the transparent frame; a wavelength converting layer for converting a portion of the light produced by the light generating element into light having wavelengths within a second wavelength range, substantially covering the light emitting surface and at least part of the transparent frame; and a scattering frame configured to substantially scatter light that travels therein, covering a portion of the light emitting surface around periphery thereof to thereby receive a portion of the light leaving the wavelength converting layer around the periphery of the light emitting area. Light components in said portion of the light are substantially mixed in the scattering frame. |
