METHOD FOR MANUFACTURING NANO DIFFUSION SHEET AND DIFFUSION SHEET FOR LED LIGHTING USING THE SAME

摘要

PURPOSE: A manufacturing method of a nano-diffusion plate and the diffusion plate for an LED lamp are provided to improve the brightness of an LED lamp by using nano-phosphors manufactured with desired optical characteristics. CONSTITUTION: A manufacturing method of a nano-diffusion plate includes a first step (S10) manufacturing a nano-phosphor solution that nano-phosphors are dispersed in toluene; a second step (S11) exchanging the toluene for formamide in the nano-phosphor solution; a third step (S12) mixing resin for light diffusion in a nano-phosphor solution source that the nano-phosphors are dispersed in the formamide; a fourth step (S13) adding a certain amount of a hardener to the nano-phosphor solution source with the resin for light diffusion; and a fifth step (S14,S15) forming a light emitting layer by making mixtures in the nano-phosphor solution source sink due to specific gravity differences after injecting the nano-phosphor solution source to a body.
