Soraa's third-generation GaN-on-GaN LED boosts efficiency by 30%

Soraa Inc of Fremont, CA, USA, which develops solid-state lighting technology built on ‘GaN on GaN’ (gallium nitride on gallium nitride) substrates, has launched what it claims is the world’s most efficient LED, which it will integrate into the market’s first full-visible-spectrum, large-form-factor lamps.

Soraa’s third-generation (Gen3) GaN-on-GaN LED achieves what is reckoned to be record wall-plug-efficiency of 75% at a current density of 35A/cm2 and a junction temperature of 85°C (outperforming the nearest competitor by 20% under normal operating conditions). Soraa says that in just one year it has achieved a 30% increase in white lumen per watt (lm/W) efficiency over its prior-generation LED. “We expect to repeat these significant year-over-year performance gains in the future,” says CEO Jeff Parker.

Soraa leverages the properties of the native GaN substrate and a chip-on-board LED package design to create a robust, single-point source that enables what is reckoned to be excellent beam control. Also, with a proprietary three-phosphor combination, the Gen3 LED emits full-visible-spectrum light (including violet), which excites optical brightening agents and perfectly renders whiteness as well as colors, it is claimed.

The Gen3 LED will be available in second-quarter 2014 in a variety of products (modules, large-form-factor PAR and AR lamps, and MR16 lamps).

Soraa’s full-visible-spectrum PAR30L lamp, powered by its Gen3 LED, will have a color rendering index (CRI) of 95 and R9 of 95, and a center-beam intensity (CBCP) of 28,250cd at 8° beam angle (10% higher than the CRI-85 offering of the nearest competitor, it is reckoned).

Soraa will display its new full-visible-spectrum large lamp products in booth #805 at Strategies in Light in Santa Clara, CA (25-27 February) and in booth# 4.1 B55 at Light + Building in Frankfurt, Germany (30 March – 4 April).
