High Uniformity TIR Lenses for LZP Emitter Family LLNF-4T11-H LLFL-6T11-H LLWF-6T11-H Key Features Total Internal Reflection (TIR) optics provides a well-controlled beam Designed specifically for LED Engin LZP emitter family Provides excellent color uniformity and quantity of light in a beam Smooth light gradient eliminates hot spots and rings and minimizes glare for superior illumination UL-rated optical grade PMMA lens material allows use of high current and temperature conditions Lenses are available standard with holder that mount easily onto LuxiGen LZP MCPCBs Simple fastening of holder to MCPCB with appropriate adhesive, e.g. epoxy or polyurethane based Typical Applications Down lighting Architectural lighting Entertainment Stage and Studio lighting Accent lighting Description This lens family couples with the compact, high-flux density LZP LuxiGen emitter family providing a range of beam options and opening up new applications in down lighting, architectural and stage and studio. The TIR lens collimates the LED light into efficient, well-controlled light beams that maximize the usable lumens in the target area. Not only does this lighting solution provide the throw or distance required for these lighting applications, it does so with a smooth, high quality beam of superior intensity uniformity, color over angle mixing, and with an absence of discomfort glare or shadows. With its performance and small footprint, the LZP emitter-lens combination offers a compact replacement solution for 35W Metal Halide lamps. COPYRIGHT 2018 LED ENGIN. ALL RIGHTS RESERVED.

Lenses can also be ordered without the holder. Replace H with O for this option. 2. Beam angle is defined as the full width at 50% of the max intensity (FWHM). 3. Field angle is defined as the full width at 10% of the max intensity. 4. Optical efficiency is defined as the ratio between the incoming flux and the outgoing flux. 5. On-axis intensity is defined as the ratio between the total input lumen and the intensity in the optical center of the lens.
