Lumileds upgrades LUXEON 5050 LED to 175lm/W

LED maker Lumileds of San Jose, CA, USA has introduced an upgraded LUXEON 5050 LED with what is claimed to be the best performance of all multi-die emitters on the market, reaching luminous flux of 350 lumens and luminous efficacy of 175 lumens per watt (lm/W) at 2W drive conditions, at a correlated color temperature (CCT) of 4000K, and a color rendering index (CRI) of 70 at 85°C.

With newly released LM-80 reliability data, the product also meets DLC Premium V4.1 requirements, enabling fixture manufacturers’ access to high utility rebates and energy savings.

In addition, the round 4.6mm light-emitting surface (LES) eases optic design. “The majority of commercially available 2W optics can use LUXEON 5050, which leads to the best flux, efficacy and color over angle combination,” says Kathleen Hartnett, senior director, product marketing. With what is claimed to be the industry’s lowest thermal resistance (2K/W), LUXEON 5050 further enhances performance by removing heat and reducing heat-sink requirements, adds the firm.

The LUXEON 5050 is suitable for high-bay and street lighting applications. Typically for high-lumen fixtures that require high efficacy, a group of standard mid-power LEDs would be used, with the tradeoff of a large fixture size and weight. In contrast, using LUXEON 5050 enables a smaller overall system size, so very compact fixtures are possible.

The LUXEON 5050 is available in a range of color temperatures (2700–6500K) and CRI levels (70, 80, 90) to meet a variety of high-bay and street lighting as well as indoor spotlighting needs.
