Lumileds launches LUXEON HL4Z undomed power LED

LED product and lighting maker Lumileds LLC of San Jose, CA, USA has released the LUXEON HL4Z undomed power LED, intended for applications that require very high intensity and superior efficacy.

Optical designers and engineers must typically make a tradeoff between optimizing optical design and achieving high efficacy. Lumileds addresses this with its LUXEON HL4Z. At the maximum drive current of 3.5A, the undomed LED delivers intensity of over 1400lm from its 2.16mm x 2.16mm light-emitting surface at 85°C. Also, at 70CRI, 4000K, 85°C and 700mA, typical luminous efficacy is 189lm/W.

Options include correlated color temperatures (CCTs) of 3000K, 4000K, 5000K, 5700K and 6500K, and color rendering indexes (CRIs) of 70, 80 and 90.

The LUXEON HL4Z comes in an industry-standard 3535 package with a 3-stripe footprint. A large thermal pad allows high drive currents and close-packed LEDs.

“There are many applications from stadiums to torches and even forward lighting on bicycles, mopeds, e-bikes and motorcycles that require very high-intensity light and, until now, the pursuit of application efficiency has required a compromise in optical design,” says Noman Rangwala, head of product marketing & management. “LUXEON HL4Z resolves the dilemma by delivering the output, intensity and efficacy that simply make the intended application better than has previously been possible.”

The LUXEON HL4Z is available directly through Lumileds’ distribution network, which includes Future Electronics and Mouser.
