High Efficiency TIR Lenses for LZ4 Emitter Family
LLNS-2T06-H, LLNF-2T06-H,
LLFL-2T06-H
Key Features
Total Internal Reflection (TIR) optics provides a well-controlled beam
Designed specifically for LED Engin LZ4 4-die emitter family
Maximum Lux on Target 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 LZ4 MCPCBs
Simple fastening of holder to MCPCB with appropriate adhesive, e.g. epoxy or polyurethane based
TM
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 LZ4 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.

Notes:

2.
LLNS-2T06-H and LLNF-2T06-H consist of a through light tunnel along the center axis of the lens, thus might not be suitable for outdoor application.
LLFL-2T06-H light tunnel is sealed off at the top surface and thus suitable for outdoor application.

Assembly Instruction
Lens holders can be assembled to the PCB using an epoxy or polyurethane-based adhesive (example: Dow Corning
3145 RTV).
Cyanoacrylate (superglue) adhesive should not be used to avoid contamination of the lens (blooming of the
epoxy).
When integrating the lens into a fixture without the lens holder, special attention is needed to maintain the
distance between the lens bottom and the emitter top. Variation in this distance will result in variation of the
beam profile. See mechanical detail B. on previous page.
Lens Cleaning
Use a lint-free soft cloth to dust off the lens. For deeper cleaning a solution of neutral detergent (example:
dishwashing soap) can be used. Do not use any solvents or abrasive liquid/fabric.

LED Engin, an OSRAM business based in California’s Silicon Valley, develops, manufactures, and sells advanced LED
emitters, optics and light engines to create uncompromised lighting experiences for a wide range of
entertainment, architectural, general lighting and specialty applications. LuxiGenTM multi-die emitter and
secondary lens combinations reliably deliver industry-leading flux density, upwards of 5000 quality lumens to a
target, in a wide spectrum of colors including whites, tunable whites, multi-color and UV LEDs in a unique patented
compact ceramic package. Our LuxiTuneTM series of tunable white lighting modules leverage our LuxiGen emitters
and lenses to deliver quality, control, freedom and high density tunable white light solutions for a broad range of
new recessed and downlighting applications. The small size, yet remarkably powerful beam output and superior insource color mixing, allows for a previously unobtainable freedom of design wherever high-flux density, directional
light is required. LED Engin is committed to providing products that conserve natural resources and reduce
greenhouse emissions; and reserves the right to make changes to improve performance without notice.
