LED maker Philips Lumileds of San Jose, CA, USA claims that its newest high-power emitter, the LUXEON Z ES, offers industry-leading color consistency through a 1-step MacAdam ellipse in warm-white color options. With a micro-footprint, undomed design and full spectrum availability, LUXEON Z ES enables high lumen density with precise optical control, adds the firm. In applications such as retail, where superior beam angles and high efficacy are crucial, the illumination-grade emitters help to lower costs while offering best-in-class white light, it is claimed.
The LUXEON Z ES is available with below black-body binning, a key feature required for color perception in specialty retail and hospitality applications. It also offers 10-15% better color-over-angle (CoA) over standard domed emitters for higher quality of light needs in indoor applications, it is claimed, making it suitable for GU10, BR30 and A19 lamps, for example. In directional light sources such as an MR16 lamp, the undomed design allows better optical coupling for greater luminance at narrower beam angles and better color consistency.
The LUXEON Z ES is the industry’s first LED platform that combines high luminance in a 1-step MacAdam Ellipse option offering optical control in the smallest available footprint, claims Raj Malhotra, product line manager of the LUXEON Z family. “The micro-footprint of LUXEON Z ES means that manufacturers can use optical solutions that are 25% smaller, yet offer the same light quality that larger, domed solutions can achieve.” The LUXEON Z ES will give lighting designers high flexibility and reduce costs, he adds.
The LUXEON Z and Z ES emitters are offered over a range of CCTs of 2700-6500K with 5-, 3- and a first-ever 1-step MacAdam Ellipse binning option, enabling the next generation of high-efficiency tunable solutions with a combination of different colors, including white CCTs, lime, blue, PC amber and red. The LUXEON Z ES is also usable in outdoor applications, where beam angle and high efficacy are key.
