Luminus, Fraen optimize LED lighting output

02 May 2012

Novel LED optics delivers high center beam power and uniformity for retail lighting.

At April’s Light + Building show in Frankfurt, Germany, Fraen Optics and Luminus Devices announced the release of the FML series of optics, which are designed to maximize the performance of Luminus's SST-90 and SSM-80 LEDs.

The range of total internal reflection optics, in conjunction with Luminus Big Chip LED technology, establishes a new performance benchmark for power, uniformity and efficiency. When mated with Luminus' SST-90 warm white LED, the FML spot optic produces a full divergence angle under 10-degrees with an industry leading l7,000 candela and Energy Star compliant efficacy. The FML series consists of a complete range of optics with output beam patterns including spot, narrow, medium, wide, elliptical and flood.

"We believe that the new FML optics from Fraen are truly game changing," said Chuck DeMilo, Global Director of Product Marketing for Luminus. "The FML optics enable our customers to capture and deliver the lumens on task at unprecedented levels of intensity, efficiency and uniformity. Using an LED to outperform a 50W MR-16 halogen lamp used to be a dream, but the combination of technologies from Luminus and Fraen has made this a reality."

TIR optics are frequently preferred over reflectors due to higher optical efficiency and center beam brightness in spot lighting applications. According to David Cohen, Chief Operating Officer of Fraen Optics, "Fraen really pushed the limits of physics with this new family of optics. Part of the secret sauce with the FML series is an innovative optical mixing chamber that homogenizes the input from the LED to deliver a stunningly uniform beam."

Cohen added, "Luminus LEDs are unique because optically they can be considered a high intensity point source of light, and this opens many new degrees of freedom for our optical designers."

Luminus Devices develops and makes LED solutions for the global illumination market. Its high efficacy and high brightness LEDs are used by many of the world's biggest companies for general lighting, projection display, entertainment, ultraviolet curing, medical, portable, transportation and digital signage lighting applications.

Fraen Optics, a Division of Fraen Corporation, specializes in the manufacture of optics for high-powered LEDs. The company offers a wide range of standard products for all major LED manufacturers as well as custom-optic design services. Fraen's divisions include its Advanced Manufacturing Division, which manufactures stepper motors; its Custom Manufacturing Division, which specializes in lighted-plastic parts and complex stampings; and Fraen Machining Corporation, which manufactures precision-turned metal components.
