<P>PROBLEM TO BE SOLVED: To provide a reflective material composition having high reflection characteristics even for ultraviolet light having a wavelength of 400 nm or less and capable of producing a reflector having high heat dissipation and heat resistance, and to provide a reflector using the reflective material composition and a semiconductor light-emitting device. <P>SOLUTION: The reflective material composition contains boron nitride particles and a heat-resistant binder, and the reflector is produced by hardening the reflective material composition. The semiconductor light-emitting device is provided, on a substrate, with an optical semiconductor element and the reflector disposed around the optical semiconductor element in order to reflect light from the optical semiconductor element in a predetermined direction. At least a part of the light reflecting surface of the reflector is a hardened product of the reflective material composition. <P>COPYRIGHT: (C)2012,JPO&INPIT |
