LEDiL Announces Availability of Lenses Qualified for Use with Cree's New XB-D LEDs

LEDiL announces the availability of 40 lenses qualified for use with Cree’s new XLamp® XB-D LED, which boasts the industry’s smallest lighting-class footprint of 2.45 mm x 2.45 mm. The wide-range of lens styles offered by LEDiL provides multiple design choices and beam patterns in the quest to drive higher performance and reduced system cost. Use of secondary optics characterized for a specific LED and engineered to provide usable light only where needed helps to reduce the number of LEDs required in a lighting system, which leads to smaller power supplies and heat sinks and reduced system cost.

Available single-position TIR (total internal reflection) lenses include 9.9 mm, 16.1 mm and 21.6 mm outside dimension, with FWHM beam angles from 8 degrees through 73 degrees, plus many oval beam patterns. These lenses cover almost all lighting needs and are often deployed in wide-area illumination, cove and wall-wash, task lighting and indoor effect lighting. Three-position and four-position lens arrays, in 35 mm, 40 mm and 50 mm diameter, achieve beam angles between 11 degrees to 52 degrees FWHM, are ideal for development of highly efficient MR-type spot lights. Designers of street lights, parking lot and garage lights, and high bay and similar commercial lights can choose from five different STRADA lenses that offer asymmetric light distribution patterns. Under-cabinet and interior mood lighting is also enabled with the performance of XB-D and LEDiL’s range of optical solutions.

“The rapid adoption of lighting-class LEDs as superior alternatives to traditional, energy inefficient or environmentally unfriendly light sources such as incandescent, halogen and fluorescent bulbs requires a good selection of secondary optics,” said Robert Derringer, LEDiL Director of Business Development. “Swift introduction of optics when new LEDs are released to the market remains a top priority for LEDiL as we help to expand the markets and applications served by Cree. And, if our standard offering of products – which now approaches 1000 different lenses and reflectors – does not meet market needs, LEDiL is willing and able to support rapid deployment of modified or custom solutions.”

LEDiL’s designers are experienced at engineering precision optics that provide 90% or higher efficiency, with good beam cut-off and color consistency. Outdoor applications benefit from LEDiL’s use of UV-stabilized, optical-grade PMMA. This material, which has outstanding resistance to ultraviolet radiation, also offers good resistance against scratches and other effects of outdoor exposure. Ease-of-use is achieved, in many cases, with molded location pins for precise mounting and pre-installed automotive grade adhesive tape.
