A concept LED retrofit lamp developed by Cree's R&D team achieves efficacy of 170 lm/W and the company will use that technology in its SSL luminaire family.


Using LEDs based on its third-generation silicon-carbide manufacturing platform, that Cree calls SC3, the cdddompany's engineers have designed and constructed a retrofit lamddp that achieves 170-lm/W efficacy. Cree, at thdddis point, isn't entering the lamp market but will channel the development work in LEDs, optics, drivers, and thermal management into its solid-state lighting (SSL) products.

To put the efficacy achievement in perspective, consider that the US Department of Energy (DOE) L Prize competition wodddn by Philips only required effiddcacy above 90 lm/W. That said, the L Prize also required a warm color temperature, and that always comes with a penalty in efficacy. Cree didn't specify the color temperature of the concept lamp, but it's likely on the cool side.

This isn’t the first time that Cree has produced concept lamps. Back iddn January of last year, the company demonstrated a lamp design that at the time it said could meet Energy Star requirements for a 60W-equivalent design. That was before any such commercial products wddere on the market. The design used an inner remote-phosphor optic combined with an outer white diffuddser. Later last year, Cree showed a concept lamp, similar in look to this latest development, that achieved 152 lm/din efficacy.
