High Power Optoelectronics (HPO) is the world's one and only professional manufacturer of full gamut (from 365 nm UV to 940 nm IR light), vertical-structure LED chips, holding the world's oldest LED-single crystal substrate wafer bonding patent. This wafer bonding process turns the original substrate into a silicon substrate after MOCVD epitaxial growth, giving LED chips exceptional thermal conductivity, and allowing them to provide even better luminous efficacy under high current and increased component reliability.
