LEDiL Adds Three New Series to Its Extensive Range of High Quality LED Optics

LEDiL expands its popular precision-engineered STRADA Series to include the new STRADA-F Series lens family. Furthermore LEDiL introduces the precision-molded MR11 (32.4mm and 35mm diameter versions) MINNIE reflector series and JULIA-A lenses to its already extensive range of precision-engineered rotationally symmetrical lens.

STRADA-F Series:
STRADA-F Series are compact lenses, 15.4mm wide x 19.6mm long, molded from UV-stabilized optical-grade PMMA plastic, boasting over 90% transmission efficiency. STRADA-FT, 8.2mm high, directs light in a forward peak of 55 degrees. The slightly taller (10.8mm) STRADA-FW offers a wider emitting pattern in a forward peak of 55 degrees.  STRADA-F Series is optimized for peak performance with LEDs from Cree, Philips Lumileds, Osram, Nichia and others.

In addition to the outstanding optical performance and reliability designed into STRADA-F Series, ease of assembly is also optimized. Locating pins ensure precise alignment of the lens over the focal point of the LED light source. The product is available with or without pre-mounted polyurethane foam adhesive tape and is also designed to fasten to the PCB using secondary screws.

With the addition of STRADA-F Series, LEDiL’s STRADA family of products – 10 different styles offered in various symmetrical and asymmetrical light distribution patterns - can be combined in a single fixture to allow manufacturers of wide-area light fixtures – such as roadway lighting, parking lot lighting, security lighting, vertical wall packs, outdoor area lighting and shoe boxes – to design efficient and compact products that meet IESNA standards. Challenging light cut-off requirements can be satisfied with simple reflective shades incorporated in the fixture design. LEDiL’s team of optical and mechanical engineers is available to assist its customers with the right selection of STRADA products for each application.

Lighting designers are rapidly developing LED-based solutions that take advantage of the up-to 80% reduction in power afforded by solid-state technology and the long-life span of LEDs. LEDiL’s STRADA Series of lenses allow immediate deployment – with no tooling investment – of LED-based fixtures to replace traditional metal halide, high-pressure sodium, and other traditional light sources used in exterior lighting applications. The high efficiency of STRADA Series products helps designers achieve Energy Star compliance through the use of fewer LEDs and electronic components.

MINNIE Reflector Series:
LEDiL’s precision-molded MR11 (32.4mm and 35mm diameter versions) MINNIE reflector series allows for rapid deployment of new lighting solutions using Cree MT-G LEDs. Lighting designers now have a more reliable, low-cost choice than traditional drawn or spun metallic reflectors.

Molded from durable polycarbonate plastic resin, the optimal optical geometric design achieved in the design process is reproduced in the molding process. The reflectors, currently available in 26, 36 and 74 degree FWHM (full width half modulation) beam patterns, are finished in an aluminum coating with a protective lacquer finish and provide greater than 90% optical efficiency. The product is also available with a secondary adapter base that easily fastens to the PCB for quick attachment of the reflector cup to the adapter, making MINNIE simpler to mount than traditional metallic reflectors.

Lighting designers are rapidly developing LED-based solutions that take advantage of the up-to 80% reduction in power afforded by solid-state technology and the long-life span of LEDs. LEDiL’s MINNIE reflectors allow immediate deployment – with no tooling investment – of LED-based fixtures to replace traditional halogen or incandescent bulbs in applications where directed light is favored, such as in spotlights in retail displays, meeting rooms, or in restaurants and bars. MINNIE reflectors are also ideal for use in museums and galleries as there are no damaging UV rays or heat in the beam.

JULIA-A Rotationally Symmetrical Lens Series:
JULIA-A is a rotationally symmetrical lens that produces batwing light emission pattern, which allows LEDs such as Cree’s XP Series or Philips Lumileds’ Rebel and Rebel-ES Series, to achieve over 90% uniformity on display surfaces 50 – 100mm from the PCB. Since these and other similar LEDs are inherently point-sources of light, JULIA-A lenses enable the LEDs to be used in a wide-variety of backlighting applications.

Typical applications include backlight roadway signage and channel letters, architectural effect lighting, under-cabinet and cove lighting, as well as museum and display lights. Other enabled applications include 360⁰ warning beacons, backlighting of emergency lights and exit signs, and interior mood lighting on vehicles such as buses, rail coach cars and commercial aircraft.
JULIA-A achieves light distribution with greater than 90% uniformity when directed to a parallel surface located between 50mm and 100mm from the PCB. Recommended LED spacing is 100mm. The lens is less than 19mm in diameter and only 4.66mm tall (4.81mm with optional tape). Precise mounting is ensured by the addition of two 0.63mm mounting pins and the product is available with optional automotive-grade polyurethane foam mounting tape for easy and reliable installation. LEDiL molds JULIA-A from optical-grade, UV-stabilized PMMA plastic.

Lighting designers are rapidly developing LED-based solutions that take advantage of the up-to 80% reduction in power afforded by solid-state technology and the long-life span of LEDs. LEDiL’s JULIA-A Series allows today’s efficient and cost-effective high-power LEDs to be used in a wide-range of backlighting applications, replacing traditional incandescent, neon, and halogen light sources. The high efficiency of JULIA-A lenses helps designers achieve Energy Star compliance through the use of fewer LEDs and electronic components.
