Luminus launching PhlatLight LEDs for lighting applications

Luminus Devices Inc of Billerica, MA, USA will be unveiling its PhlatLight LED product line for lighting applications during next week's Lightfair International event (28-30 May) in Las Vegas, NV.

The firm is best known for supplying its patented PhlatLight LEDs for high-definition TVs and projectors to consumer electronics manufacturers like Samsung and LG Electronics. The firm claims that they are the only LEDs bright and efficient enough to replace arc lamps with a solid-state alternative.

PhlatLight LEDs are larger than standard LEDs, and are designed to operate at much higher power levels. Luminus is therefore now making the technology available to lighting manufacturers, providing a line of products that are able to replace conventional lamps in lighting applications previously thought impossible with LEDs.

“Luminus has taken several steps in recent months to support expansion into lighting, by expanding our product portfolio, sales and support organization, and distribution channel,” said Christian Hoepfner, VP of products. “These products are already being designed into lighting fixtures in the entertainment, architectural and medical industries,” he adds. “We expect our large, white PhlatLight LEDs to make an impact in high-brightness applications in the general lighting landscape.”

The properties of PhlatLight LEDs include Luminus’ Photonic Lattice technology efficiently extracting light from the chip surface. The firm says that the technology enables the manufacture of large LEDs as much as 12 times larger than conventional LEDs, in various shapes, sizes and configurations for a wide range of applications.

Luminus’ patented chip-on-board package technology gives the LEDs low thermal resistance (< 0.6 oC/W), allowing what is claimed to be the industry’s widest reliable operating range, from 0.35A to over 30A, with some devices capable of producing over of 3000 lumens from a single chip. Reliability testing at high current levels qualifies the products for over 100,000 hours of operation.

Three series of PhlatLight LEDs will be exhibited at Lightfair:

  • The PhlatLight CBT series of single-chip, single-color LED modules comprises individual red, green or blue devices with various emitting areas: CBT-120 (12mm²); CBT-85 (8.5mm²); CBT-54 (5.4mm²); CBT-40 (3.9mm²). Products are available for sampling now.
  • The CBM family of multi-chip, multi-color PhlatLight LED modules will be debuted in three- and four-color configurations. With thousands of lumens emitted from a small area like an arc gap or filament, optics are simplified and color shadowing eliminated. Over 2000 lumens of multi-color or white light is produced from a single module. This performance enables applications not possible with conventional LEDs, it is claimed, such as spotlighting for entertainment, architectural or general lighting. A single CBM module can replace large arrays of conventional LEDs, while multiple modules can be tiled for flux competitive with 575W arc-lamps. Sampling will start in September, with mass production in Q4/2008. The initial CBM series will consist of the following devices, with different emitting areas: CBM-220-RGB (22mm²) and CBM-270-RGBX (27mm²), with multiple fourth colors available Q4/2008.
  • A new family of PhlatLight white LEDs in various sizes offers output ranging from 1600 lumens for the CBT-90 and more than 4000 lumens for the CBM-360, providing an ultra-bright, point-source of white light with superior optical coupling that enables new applications with better optical system efficiency, it is claimed, overcoming the design limitations of conventional LEDs and LED arrays. Sampling is planned for September, with mass production in Q4/2008. The initial white LED product line will consist of the following devices (each in cool, warm, neutral version): CBT-90-W (9mm²) and CBM-360-W (36mm²).

Luminus adds that PhlatLight LEDs are supported by eco-system partners for lighting including National Semiconductor and Maxim for drivers, Fraen for optics, NuVentix for thermal management and Cypress Semiconductor for color management solutions.
