Manufacturing method of non-planar white light emitting diode apparatus using yellow phosphor paste composite capable of spin and spray coating

摘要

The present invention, SiO ₂ 14~28.0 mol%, B ₂ O ₃ 31~45.0 mol%, ZnO 20.4~34.0 mol% and Al ₂ O ₃ 10 to 40% by weight of SiO ₂ -B ₂ O ₃ -ZnO-Al ₂ O ₃ glass frit containing 0.6 to 9.0% by mole, 60 to 90% by weight of a yellow phosphor, a total content of the glass frit and the yellow phosphor of 100 relative to the weight section, and includes an organic binder solution is 15 to 45 parts by weight, the softening point of the SiO ₂ -B ₂ O ₃ -ZnO-Al ₂ O ₃ based glass frit is lower than 500 ℃, the glass frit, the yellow phosphor and the Wherein the organic binder solution is diluted with 50 to 100 parts by weight of n-butyl acetate based on 100 parts by weight of the total amount of the organic binder solution, a method for producing the non-flat type white light emitting diode device using the same, Planar white light emitting diode device. According to the yellow phosphor paste composition of the present invention, the low-softening point glass frit and the yellow phosphor are uniformly dispersed, chemically stable, resistant to temperature and humidity, cracked during long-time use, It has excellent light efficiency, easy to control film thickness, high stability of coating, can be applied by spin coating and spray coating method which is a liquid process, and can be applied to a remote phosphor phosphor type packages, and a color glass lens can be manufactured using the yellow phosphor paste composition and applied to a non-flat type white light emitting diode device.
