Pyramid
The Pyramid Series Multi-Pattern Prismatics are designed to provide controlled light distribution, glare reduction, and enhanced visual comfort through a multi-faceted pyramidal prism geometry. By combining symmetrical prism faces with controlled facet angles, this series balances luminous efficiency with effective high-angle luminance control, making it suitable for a wide range of architectural and technical lighting applications.
Unlike linear prisms, pyramid geometries distribute light in both longitudinal and transverse directions, resulting in a more uniform luminance appearance and reduced directional artifacts. The Pyramid Series is available in multiple materials and configurations to meet optical, mechanical, and regulatory requirements across different environments.

Pyramidal Geometry Benefits
Pyramidal microprism geometry uses multi-directional facets to refract and redirect light evenly across horizontal and vertical planes. This enables controlled beam shaping while maintaining high optical efficiency.
Key geometry advantages include:
- Multi-directional glare control through symmetrical prism facets
- Reduction of high-angle luminance contributes to improved visual comfort
- Balanced light distribution without linear banding effects
- Improved uniformity compared to single-axis prism structures
- Lower risk of moiré patterns when paired with LED arrays
- Efficient use of optical surface area, preserving lumen output

Applications
Optical Behavior Explanation
Pyramid prisms refract incoming light through multiple angled facets, redirecting high-angle rays away from direct sightlines while maintaining useful forward illumination. This results in a controlled luminance profile that reduces glare without relying on heavy diffusion.
Compared to linear prisms, pyramid optics provide more isotropic light control, minimizing directional artifacts. Compared to purely diffusive materials, they preserve higher luminous efficacy by controlling light through refraction rather than scattering.
