Mar 16, 2016: Lumileds introduces the perfect upgrade for an industry standard LED package, the Luxeon 2835 Line. Luxeon 2835 LEDs are available in five configurations of light output and string voltage and ESD protection to meet a variety of illumination application needs 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,” explains Matthew Everett, Senior Director of Mid Power Products.
To cater to the market, the Luxeon 2835 is offered in two light output ranges: Luxeon 2835C for higher efficacy and an industry-leading 240mA maximum drive current with 3V and 6V options and Luxeon 2835E for the most cost-effective retrofit lamp designs with 6V and 9V options. Makers of low-cost retrofit bulbs targeting soft white (2700K, 80 CRI) will benefit from the Luxeon 2835E 9V, which produces 72 lumens at 134 lm/W when driven at 60 mA.
For entry level bulbs, a lighting manufacturer might choose the Luxeon 2835E 6V, which produces 49 lumens with the same efficacy. Dimmable bulbs, LED candles and downlight manufacturers might choose the Luxeon 2835C 6V, which produces 103 lumens at 138 lm/W in 2700K and 80 CRI when driven at 120 mA. 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 Luxeon 2835C 3V is available in two versions, one with a TVS (Zener) and one without. The 2835C 3V LED without TVS produces 58 lumens at 156 lm/W in 4000K and 80 CRI when driven at 120 mA.
The Luxeon 2835 Line is offered across a CCT range or 2700K – 6500K at 70 and 80 CRI. All Luxeon 2835 6V & 9V LEDs are hot-color targeted to ensure the color remains within ANSI bin specifications under typical application conditions. Micro color binning allows customers to easily create 3, 4 or 5 step MacAdam Ellipse kits. The Luxeon 2835 Line is one of the breakthroughs introduced during Lumileds Mid Power March 2016.
