Backlight Optic With TIR Structure for Light Trespass Control

The optical device segments the light distribution control into multiple functional zones using distinct optical features. The first optical feature controls light in a first angular range, the second optical feature controls light in a second angular range, and the third optical feature controls light in a third angular range. This segmentation allows precise control of light distribution to eliminate spillage while maintaining manageable device complexity through modular optical design.

Different portions of the optical device have different optical properties tailored to specific directional requirements. The first optical feature has properties optimized for redirecting light at certain angles, while the second and third optical features have different properties for other angular ranges. This local differentiation of optical quality enables precise control over light spillage in specific directions without requiring the entire device to be overly complex.

The optical device dynamically controls light distribution across different angular ranges using three distinct optical features that operate simultaneously. Each feature actively redirects light into specific angular ranges, creating a dynamic light distribution pattern that maximizes illumination of the target volume while minimizing light trespass to avoided volume. This dynamic control achieves high productivity without harmful light spillage.

The invention controls light distribution by introducing angular dimensionality through three distinct optical features that manage different angular ranges. Rather than simply directing light forward, the device manipulates light in the angular dimension, redirecting light at various angles to ensure it reaches the target volume while preventing trespass. This dimensional approach to light control simultaneously improves efficiency and eliminates harmful effects.

The optical device merges multiple optical control functions into a single integrated structure. The first, second, and third optical features are combined within one optical device, allowing them to work together to eliminate light trespass. This merging approach achieves the benefit of complex light control while avoiding the drawback of multiple separate devices, thus managing overall device complexity effectively.

The optical device performs multiple functions simultaneously through its three optical features: controlling light in the first angular range, controlling light in the second angular range, and controlling light in the third angular range. This multi-functionality allows a single device to eliminate light trespass across all directions without requiring multiple separate components, thereby achieving comprehensive light control while maintaining reasonable device complexity.
