Based on the self-exposure planar phosphor coating technique, which adopted a kind of water-soluble sensitive glue consisting of Polyvinyl Alcohol (PVA) and Ammonium Dichromate (ADC). This method adopted the blue light exposure by itself which could obtain controllable phosphor layer. Finally, by using the plasma stripping, only phosphor’s planar coating layer could be obtained. Luminous efficiency, spectrum of light output and color uniformity of different packing structures were measured by the nine point’s method. Experimental results show that the uniformity of white LED obtained by this technique is better than that obtained by the traditional dropping glue technology and sprays coating technology. And the luminous efficiency is as good as the other two technologies.
