The Luxeon v package led can be driven under 5A, positioning for high lumen applications, including high-low end lamps, stadium lighting and outdoor area lighting.
Lumileds released a new Luxeon v high-power package led that can drive to 15W levels and for a variety of high lumen output applications, including stadium lighting, high and low voltage lighting and outdoor lighting. In fact, Lumileds said, this compact, single mode LED can provide more than 1700 LM under 5700K CCT, providing a CRI for 4.8A drives, which is equivalent to the LM effect.
Lumileds boldly claims that Luxeon V is 50% higher than the lumen output of competing products. At the same time, the 4040-pack LEDs are also considered to be 60% more heat-resistant than competitive products. Kathleen Hartnett, senior director of Lumileds's product marketing, said, "Luxeon v implements the design of lighting for stadiums and areas, and uniquely combines high efficiency with very low heat resistance and optimized radiation patterns in highly driven currents." ”
The performance of the LED manufacturer against the competitor is difficult to verify because physical properties such as transmitter and package size are usually different, or different manufacturers report performance under different driving currents and CCT/CRI combinations. In addition, the most competitive Cree xhp (Extreme high power) led with Luxeon v products is a multiple launcher design.
Luxeon v Marks lumileds first single high-power package LED
Product developers are most likely to compare the Luxeon V series with LEDs in 3535 or smaller packages. For example, Cree publishes the XLamp Xp-l series and the latest 3.45x3.45 mm encapsulated XP-L2 LEDs. XP-L2 can provide 1175 LM under 3 a current. It seems that Lumileds can drive its newest chips at a higher power density level, which can be achieved by improved thermal resistance.
However, many product developments focus on optimizing the maximum drive current to achieve higher performance. Lumileds can be driven with a large current of up to 1.4A. 5700K, 70-CRI models can provide 580 LM or 148 LM, while the 3000K-CCT version drops down to 545 LM or 140 lm.
On the official web, Lumileds said, "Luxeon V is a high-power transmitter based on a chip-level package (CSP) that provides maximum flux and superior reliability under extreme operating conditions." This world-class performance is achieved through technological breakthroughs in grain, encapsulation and fluorescence. Finally created a product beyond the current competitive products, the realization of leading lighting and lighting design products. ”
