New LUXEON HL4Z Delivers High Intensity, Very-High Light Output, and High Efficacy

2024-07-15 | 返回

Finally, a small, high-intensity LED that allows optical optimization – lm/mm2 without sacrificing lm/Watt

Lumileds announces the release of the LUXEON HL4Z un-domed 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 dilemma with its innovative LUXEON HL4Z. At maximum current, the undomed LED delivers tremendous intensity – over 1400lm – from its 2.16mm2 light emitting surface at 85°C. And at 70CRI, 4000K, 85°C, and 700mA, typical efficacy of the new LUXEON HL4Z is an impressive 189lm/W.

“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,” said Noman Rangwala, Head of Product Marketing and Management at Lumileds. “LUXEON HL4Z resolves the dilemma by delivering the output, intensity, and efficacy that simply make the intended application better than has previously been possible.”
