Philips Lumileds of San Jose, CA, USA has unveiled chip-on-board (CoB) arrays for PAR38-equivalent lamps that achieve 10% or greater efficacy than competing solutions, it is claimed. Also suitable for spotlights, the LUXEON CoB 1202 has luminous efficacy of 115lm/W typically, varying from 95-130lm/W depending on the correlated color temperature (CCT) and color rendering index (CRI) of the array.
"The high efficacy, combined with our lineup of compatible reflectors and drivers, enables the most affordable PAR38 and spotlight designs to date," reckons product line director Eric Senders.
The LUXEON CoB 1202 completes Lumileds' portfolio for PAR lamps. Together with the LUXEON CoB 1203, the 9mm Light-Emitting Surface (LES) versions are optimal best in price/performance for directional retrofit lamps, the firm claims. Due to the CoB 1202's mechanical and optical compatibility with the 1203, the same ecosystem can be used to create a highly efficient and cost-effective solution, Lumileds adds.
The performance range of the CoB 1202 arrays is 95-130lm/W over a range of CCTs of 2700-5700K at a CRI of 70, 80 or >90. Typical output for warm white (3000K, 80 CRI) is 800lm when driven at a current of 200mA. The warm-white arrays can be driven at up to 400mA to achieve a flux of 1500 lumens. The high-CRI (>90) versions deliver an R9 of >80 for demanding applications such as retail downlights and spotlights.
