METHODS AND APPARATUS FOR IMPLEMENTING COLOR CONSISTENCY IN REMOTE WAVELENGTH CONVERSION

摘要

There is provided an LED lighting arrangement comprising: at least one LED (404) operable to LED emit light of a first wavelength range; a wavelength conversion component (902) being remote from the at least one LED (404) and operable to emit light of a second wavelength range when excited by light of the first wavelength range, wherein emitted light from the LED lighting arrangement comprises combined light from both the at least one LED (404) and the wavelength conversion component (902); characterized by the wavelength conversion component (902) being substantially planar comprising a photoluminescent material layer, wherein the photoluminescent material layer comprises multiple print layers of photoluminescent material such that the photoluminescent material layer is thicker at a central portion thereof than at an edge portion thereof, and operable to produce a substantially uniform color of light from substantially all portions of the wavelength conversion component (902).
