Lumileds’ new LUXEON 5050 HE Plus LEDs delivers 199lm/W for outdoor and industrial lighting
With efficiency and energy sustainability being key drivers of LED selection for industrial and outdoor lighting applications, LED product and lighting maker Lumileds LLC of San Jose, CA, USA says that its new LUXEON 5050 HE Plus can deliver luminous efficacy of 199lm/W and luminous flux of 746lm, as well as reducing application power consumption by 18% or more in critical infrastructure applications common to cities and businesses around the world. Further, the lower energy consumption of the LUXEON 5050 HE Plus supports the transition to low-carbon or no-carbon electricity supply. OEMs can achieve greater sustainability in their manufacturing process by reducing the physical material in both the heatsink and the system’s driver.
As global energy costs continue to increase, efficiency gains pay increasing dividends to end-users and communities that need to lower municipal costs, reduce energy consumption, and support sustainability goals, says Lumileds. All these objectives can now be achieved while also addressing dark-sky initiatives. With correlated color temperature (CCT) options as low as 1800K and color rendering indexes (CRIs) of 70 or 80, the LUXEON 5050 HE Plus is suitable for both on- and off-grid lighting solutions, reckons the firm.
“Efficiency remains the key driver for outdoor and industrial lighting and the focus of our continuous improvement programs,” says Mei Yi, director of product marketing. “The efficacy gains achieved with our LUXEON 5050 HE Plus make it the highest-performing 5050 LED available today, and these gains offer dramatic performance advantages for on-grid lighting and solar, off-grid solutions.”
In addition to the efficacy and output combination, Lumileds has:
- reduced thermal resistance to an Rth of 1.1k/W so that smaller, less costly heatsinks can be used;
- established narrower flux bin widths of 25lm to facilitate accurate system design;
- hot-color targeted the LEDs at 85°C; and
- advanced the most robust package to support a maximum drive current of 1.2A.
The LUXEON 5050 HE Plus joins a portfolio that includes the LUXEON 5050 Round, LUXEON 5050 Square, and LUXEON 5050 HE. Both the HE and HE Plus have a square light-emitting surface. The performance advances available in the HE Plus versions is also now available in Lumileds’ SunPlus 5050 LEDs for the horticulture industry.
