Lumileds raises lumen per watt for street lighting LEDs
Luxeon 5050 features the highest flux, efficiency and robustness at excellent cost-per-lumen
Lumileds has introduced an upgraded Luxeon 5050 that sets the standard for high lumen per watt (lm/W) for high bay and street lighting applications. 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.
Luxeon 5050 features the best performance of all multi-die emitters on the market, reaching flux levels of 350 lm and 175 lm/W at 2W LED drive conditions (4000K, 70CRI at 85degC). But the advantage goes beyond superior flux. The round LES (4.6 mm), eases optic design.
"The majority of commercially available 2W optics can use Luxeon 5050, which leads to the best flux, efficacy and colour over angle combination," said Kathleen Hartnett, senior director, product marketing at Lumileds. With the industry's lowest thermal resistance (2 K/W), Luxeon 5050 further enhances performance by removing heat and reducing heat sink requirements.
Luxeon 5050 is an ideal choice for high bay and street lighting applications. Typically for high lumen fixtures that require a high lm/W, a group of standard mid power LEDs would be used, with the tradeoff of a large fixture size and weight.
Using Luxeon 5050, on the other hand, enables overall smaller system size, which means very compact fixtures are possible. Luxeon 5050 is available in a range of colour temperatures (2700K "“ 6500K) and CRI levels (70, 80, 90) to meet a variety of high bay and street lighting as well as indoor spotlighting needs.
