Lumileds boosts flux and efficacy of LUXEON 3535 2D mid-power LED by 10%

Continuing its ‘Mid-Power March’ series of product announcements, Philips Lumileds of San Jose, CA, USA says that its LUXEON 3535 2D mid-power LED (launched in May 2013) has had its typical flux output boosted by 10%, delivering optimized performance in combination with the quality of light needed for distributed light source applications, it is claimed.

Specifically, for LUXEON 3535 2D parts with a correlated color temperature (CCT) of 2700K and a color rendering index (CRI) of 90, typical flux levels have increased from 55 lumens to 61 lumens. Simultaneously, typical voltage has been lowered - resulting in an increase in luminous efficacy of more than 10%. Lumileds recons that this increase in performance will drive the adoption of LED lighting for consumer bulbs, by providing the color quality to which consumers are accustomed with their lamps.

This is in line with Lumileds’ targeted improvements in flux and efficacy for 90-CRI warm-white LEDs. Developed to address the rapidly growing market for high-color-rendering light sources, this boost in performance of 90-CRI warm-white emitters mimics the color quality of traditional incandescent bulbs. Increasingly, customers seeking retrofit lamp solutions are specifying a minimum of 90 CRI, says Lumileds. For example, the California Energy Commission (CEC) is requiring minimum CRI of 90 and R9 of 50 for light fixtures installed in California.

Lumileds says that in second-quarter 2014 it will announce further improvements in flux and efficacy for other CRI and CCT combinations in its mid-power portfolio, addressing cool-white and 80-CRI color temperatures.
