High Efficiency TIR Lenses for LZC Emitter Family
LLNF-3T08-H, LLFL-5T08-H,
LLWF-3T08-H
Key Features
Total Internal Reflection (TIR) optics provides a well-controlled beam
Designed specifically for LED Engin LZC 12-die emitter family
Maximum Lux on Target
TM
and lumens in beam
Provides the highest quality 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 LZC MCPCBs
Simple fastening of holder to MCPCB with appropriate adhesive, e.g. epoxy or polyurethane based
Typical Applications
Down lighting
Accent lighting
Track lighting
Architectural lighting
Stage and Studio lighting
Description
This lens family couples with the compact, high-flux density LZC LuxiGen emitter family providing a range of beam
options and opening up new applications in stage and studio, architectural and down lighting. 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.

Notes:
1. 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.
