Lumileds Launches LUXEON 2835 Line Of LEDs For Cost-Effective Retrofit Lamps, Downlights And Troffers

LED maker Lumileds of San Jose, CA, USA has introduced the LUXEON 2835 line as an upgrade for an industry-standard LED package.

LUXEON 2835 LEDs is available in five configurations of light output and string voltage and ESD protection for a variety of illumination applications including retrofit lamps, downlights and troffers. "The LED retrofit bulb and other application segments are taking off right now. We decided to optimize for each application requirement via different offerings within the LUXEON 2835 Line," says Matthew Everett, senior director of Mid Power Products.

To cater to the market, the LUXEON 2835 is offered in two light output ranges: 2835C for higher efficacy and what is claimed to be an industry-leading 240mA maximum drive current with 3V and 6V options; and 2835E for the most cost-effective retrofit lamp designs with 6V and 9V options.

Lumileds says that manufacturers of low-cost retrofit bulbs targeting soft white (2700K, 80 CRI) can benefit from the 2835E 9V, which produces 72lm at 134lm/W when driven at 60mA. For entry-level bulbs, a lighting manufacturer might choose the 2835E 6V, which produces 49lm with the same luminous efficacy. Dimmable bulbs, LED candles and downlight manufacturers might choose the 2835C 6V, which produces 103lm at 138lm/W in 2700K and 80 CRI when driven at 120mA. Lumileds says that a key advantage of all LUXEON 2835 LEDs is their ability to be driven at double these reference drive currents to achieve even higher flux and use fewer LEDs per bulb.

For designers of mid-range troffers, linear fixtures and downlights, the 2835C 3V is available in two versions, one with a TVS (Zener) and one without. The 2835C 3V LED without TVS produces 58lm at 156lm/W in 4000K and 80 CRI when driven at 120mA.

The LUXEON 2835 Line is offered across a correlated color temperature (CCT) range of 2700-6500K at 70 and 80 CRI. All LUXEON 2835 6V and 9V LEDs are hot-color targeted to ensure that the color remains within ANSI bin specifications at typical application conditions. Micro color binning allows users to easily create 3-, 4- or 5-step MacAdam Ellipse kits.
