LED Engin, a provider of LED products, announces the introduction of two narrow-angle TIR (Total Internal Reflection) high efficiency lenses for the company's high flux LuxiGen LZC- and LZP- series emitters. The proprietary 8-degree narrow spot lens and 15-degree spot lens are designed for use with LED Engin's compact, high flux density LZC (12-die) and LZP (24-die) LuxiGen emitters.

This combination enables an array of high brightness LEDs to be replaced by a single LED emitter and lens, cutting fixture size by at least 50% and delivering superior beam control. The TIR lenses collimate the LED light into efficient, well-controlled beams that maximize the usable lumens in the target area.

They provide the throw or distance required for many new lighting applications, and do so with a smooth beam of uniform intensity that minimizes glare and creates crisp, single shadows. The 8-degree narrow spot lens, coupled with the LZC 12-die, multi-color RGB, RGBA or RGBW emitters, provides effective in-source color mixing for dynamic color in entertainment and architectural lighting applications.

When used with white LZC or LZP series emitters, the combination can replace 35W metal halide lamps in downlighting and bay lighting applications with an efficient, cool-running unit that has a service life of 50,000 hours. On-axis efficiencies are 12cd/lm for the 8-degree lens plus LZC emitter and 8cd/lm for the 15-degree lens and LZP emitter.

Up to 36,800cd center-beam candle power can be produced by a single lens/emitter combination. The lenses, which are made from optical-grade polymethyl methacrylate (PMMA) and UL-rated, are available with holders that mount easily to LED Engin's LuxiGen metal core printed circuit boards (MCPCBs).
