Seoul Viosys starts production of rare-earth-free white LED
Original: Seoul Viosys begins production of rare-earth-free white light emitter
South Korean LED maker Seoul Viosys has begun mass production of a white light emitter that contains no rare-earth phosphors, a notable shift since conventional white LEDs rely on rare-earth elements such as yttrium and cerium. The announcement is drawing attention amid ongoing supply-chain concerns over rare-earth materials and export restrictions, with discussion focusing on what the technology means for lighting manufacturing.
