Title:
The sealing material for LED
Document Type and Number:
Japanese Patent JP6057582
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a sealing material for an LED, which secures light transmittance in the short-wavelength ultraviolet region, also has durability to heat generation by an LED device and ultraviolet rays itself, and has economical efficiency.SOLUTION: The sealing material comprises an organic inorganic hybrid composition (X) containing a dimethylpolysiloxane (A) having a hydroxy terminal, an aluminum alkoxide (B), and a silicon alkoxide (C), and produced through dehydration condensation reaction, wherein the ratio of the number of the hydroxy group of the dimethylpolysiloxane having a hydroxy terminal and the number of the alkoxy group of the aluminum alkoxide in the organic inorganic hybrid composition is 1:0.1 to 1:1.5, and the ratio of the number of the hydroxy group of the dimethylpolysiloxane having a hydroxy terminal and the number of the alkoxy group of the silicon alkoxide in the organic inorganic hybrid composition is 1:2 to 1:50. The material 1 is coated on a substrate by dropping the material on the substrate having the LED 2 mounted thereon.
