LED Diffusion
with Light Shaping Diffusers®
Precise Beam Control. Superior Uniformity.
High Transmission Efficiency.
Luminit’s Light Shaping Diffusers® (LSDs) are advanced optical diffusers engineered to transform and control LED light with precision. Utilizing proprietary holographic beam shaping technology, our diffusers go far beyond conventional plastic diffusion panels, delivering unparalleled performance in beam shaping, hotspot elimination, and light homogenization.
These highly efficient optical diffusion films and rigid sheets are available in circular, elliptical, and extreme elliptical formats, with beam angles ranging from 1° to 100°,the most comprehensive library of beam angles in the world. Whether you’re working with LED strip lights, luminaires, or specialty lighting, Luminit Light Shaping Diffusers® improve light quality, enhance aesthetics, and increase system efficacy.
What Makes
Light Shaping Diffusers® Different?
Holographic Microstructures for
Advanced Light Control
At the heart of our technology is a holographically recorded, pseudo-random surface relief pattern that manipulates light direction at the micro level. These non-periodic structures redirect light using surface scatter instead of traditional bulk diffusion, resulting in:
- Higher transmission efficiency (85%–92%)
- Minimal backscatter and Fresnel loss
- Smooth, uniform illumination without visible hotspots
- Improved beam control across the visible spectrum (400–700nm)
This microstructured optical diffusion is embedded onto ultra-clear polycarbonate films or rigid substrates, giving you top-tier optical performance in a lightweight, thin, and durable format.
How Do LED
Diffusers Shape Light Beams?
LEDs are efficient light sources, but without proper diffusion, they often create visible hotspots, harsh striations, and uneven lighting. Luminit Light Shaping Diffusers® solve these problems by homogenizing the output and reshaping the light to suit specific applications.
Our beam shaping diffusers:
- Spread LED strip light into smooth, continuous lines
- Reduce the number of LEDs needed per fixture
- Provide direct-view homogenization for displays and architectural lighting
- Improve energy efficiency by minimizing light loss
For example, a 60° x 1° elliptical diffuser spreads light widely across one axis while tightly controlling the other, perfect for applications like cove lighting or wall washing where uniformity and directionality are critical.
Types of Optical Diffusion:
Circular, Elliptical, and Extreme Elliptical
We offer three core beam shaping formats:
Circular Diffusers
Symmetrical beam control in all directions (e.g., 40°, 60°, 80°).
Best for: Downlights, flashlights, spotlights, general lighting
Elliptical Diffusers
Two-axis beam control (e.g., 60° × 10°, 80° × 50°).
Best for: Corridor lighting, accent lighting, directional applications
Extreme Elliptical (Linear) Diffusers
Highly asymmetrical diffusion (e.g., 60° × 1°) for tight directional control.
Best for: Wall grazing, shelf lighting, stairwells, cove and indirect lighting
Each format is engineered to eliminate visible striations, reduce glare, and create consistent, human-centric lighting across architectural, automotive, and high-tech environments.

Why Surface Relief
Micro-Optics Beats Bulk Scatter
Traditional diffusers rely on bulk scatter, which reduces optical efficiency. Luminit’s surface relief Micro-Optics technology enhances transmission and reduces unwanted reflection, providing higher optical performance and improved visual comfort. This makes our LED light diffuser sheets ideal for both high-output and energy-conscious applications.
