<P>PROBLEM TO BE SOLVED: To provide a hardening resin composite for sealing LEDs which provides a hardening material that is thermally hardened in a short time, has an excellent transparency and hardly changes into yellow, and thereby attains an LED package suppressed with a decline in emission luminance over time; and also to provide the LED package using the same. <P>SOLUTION: The hardening resin composite for sealing LEDs contains (A) a resin having an alicyclic structure and an ethylene unsaturated group and (B) an organic peroxide, and has at least 80% of light transmission in a wavelength region of 350-700 nm of a thermally hardening material (thickness of 1 mm). A light emitting element with the main emission peak of 550 nm or less is coated with this resin composite, and then the resin composite is thermally hardened at 100-180°C to fabricate the LED package. <P>COPYRIGHT: (C)2007,JPO&INPIT |
