T3-Glass Visual Comfort

The primary objective of this optical system was to ensure visual comfort while providing effective light coverage as a priority  

Features

• Visual Comfort
• Uniformity

Challenges

The primary challenge was to develop a continuous optical geometry that facilitates the manufacturability in Glass and achieve a gradual attenuation of light intensities at elevated vertical angles, while simultaneously preventing the formation of hotspots that could result in abrupt variations in direct illumination perceived by the observer, thereby minimizing discomfort  

Solution

The solution to achieve the desired lighting coverage while ensuring visual comfort involved utilizing zonal spherical constants as the foundational basis for the design. This approach enabled the determination of zonal lumens necessary to establish uniform intensity distribution within the range of 30 to 70 degrees. Consequently, the majority of the light output was projected within this zonal range, effectively meeting the required lighting coverage and ensuring a uniform distribution of intensities, thereby minimizing visual discomfort.

This approach used the majority of the Glass surface to concentrate the design’s performance within a 30° to 70° range, enabling a continuous geometry that improves manufacturability and ensures the required light distribution.
