Lumileds has unveiled the new Luxeon V high-power packaged LEDs that can drive up to 15W and are targeted at a variety of high-lumen output applications, including stadium lighting, high and low-voltage lighting and outdoor lighting. In fact, Lumileds said that this compact, packaged single-mode LED delivers more than 1700 lm at 5700K CCT and 70 CRI at 4.8A, which is equivalent to 110 lm / W.

 

Lumileds boldly claims that Luxeon V is up to 50% more lumen output than competing products. At the same time, the 4040-packaged LEDs are also considered 60% more thermally resistant than competing products. Kathleen Hartnett, senior director of product marketing at Lumileds, said, "Luxeon V uniquely combines luminaire design for stadiums and district lighting with high efficiency at low drive currents and extremely low heat and optimized radiation patterns "

 

Performance offered by LED manufacturers to competitors is difficult to verify because usually physical performance is different for emitter and package sizes or different manufacturers report performance under different drive current and CCT / CRI combinations. In addition, the most compelling CREE XHP (Extreme High Power) LED for Luxeon V products is the multi-emitter design.

 

Luxeon V marks Lumileds' first single high-power package LED

 

Product developers most likely compare the Luxeon V-Series to LEDs in 3535 or smaller packages. Examples include the XLamp XP-L series from Cree and the latest XP-L2 LEDs in a 3.45 x 3.45 mm package. XP-L2 can deliver 1175 lm at 3A. It seems that Lumileds can drive its latest chips at higher power densities, which can be achieved with improved thermal resistance.

 

However, many product developments focus on optimizing the maximum drive current for greater efficiency. Lumileds can be driven with high current up to 1.4A. 5700K, 70-CRI models can provide 580 lm or 148 lm / W, while the 3000K-CCT version drops to 545 lm or 140 lm / W.

 

On the official website, Lumileds said, "LUXEON V is a high-power, chip-scale package (CSP) based transmitter that delivers maximum throughput and excellent reliability under extreme operating conditions. Particle, encapsulation and phosphor breakthroughs that culminated in a product that surpasses current competing products to deliver leading-edge lighting and fixture designs. "
