High Efficiency TIR Lenses for LZP Emitter Family

LLNS-3T11-H

LLSP-3T11-H

LLNF-1T11-H

Key Features

 Total Internal Reflection (TIR) optics provides a well-controlled beam

 Designed specifically for LED Engin LZP 24-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 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 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. With its performance and small footprint, the LZP emitter-lens

combination offers a compact replacement solution for 35W Metal Halide lamps.

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.
