T3 2X6 LED 5050

This lens was carefully designed to address the challenges associated with utilizing large LEDs in standard-sized optical systems  

Features
  • No hotspot
  • Uniformity
  • High Optical Efficiency
  • Light Control

Challenges

The primary challenge was to design a geometry that mitigated the generation of hotspots beneath the luminaires. Currently, lenses utilizing a 5050 mm LED within a maximum 1-inch optical size produce high illuminance directly below the luminaire, adversely affecting average luminance values. Furthermore, commercial lenses that effectively address hotspot formation often do so at the expense of elevated backlight levels or introduce stray light within the optics, resulting in increased values in the BUG (Brightness, Uniformity, Glare)

Solution

The solution for achieving effective light control, despite the large source size, was based on the Optical system’s Etendue. The approach integrated optimization criteria and design variables, analyzing the source’s luminance and the minimum light path within the acrylic. This allowed to develop a functional model that not only met performance goals but also minimized the material’s thickness.
