Light source manufacturer Ushio Inc of Tokyo, Japan says that in November it will begin sales of Superline LEDs, a series of LED MR16 halogen replacement lamps from Soraa Inc of Fremont, CA, USA, which develops solid-state lighting technology built on 'GaN on GaN' (gallium nitride on gallium nitride) substrates. The products will be sold via Ushio's subsidiaries in countries including Japan, China, Taiwan, South Korea, Singapore and Germany.
GaN-on-GaN LEDs feature high luminous efficiency and light-extraction efficiency and also claim superior heat radiation performance. This enables both large currents and high levels of illumination to be achieved for a given area, in turn enabling miniaturization of the module (difficult to attain with conventional LED chips that use sapphire or silicon substrates). The single-core Superline LED (with just one LED module) hence enables the same or higher brightness than a standard, multi-core LED halogen replacement lamp (with multiple LED modules). It is also compatible with existing lighting fixtures for halogen lamps, since its size is equivalent to that of halogen lamps.
Ushio says that, as a series of next-generation LED halogen replacement lamps, Superline LED delivers not only the brightness of halogen lamps demanded by users, but also faithfully recreates the quality and properties of the light.
