Toshiba drops forward voltage with GaN-on-Si lighting LEDs
“Both have been developed as light sources for general lighting applications, including light bulbs, base lights, down lights and ceiling lights, street lights and floodlights,” said the firm.
They are made on a gallium nitride-on-silicon (GaN-on-Si), which is intended to reduce production cost, and performance seems similar to more conventional GaN-on-sapphire and GaN-on-SiC devices.
