Alternating White and Multi-Color LED Edgelight for Uniform Broad Color Space

The light source is segmented into multiple discrete LED assemblies (white LED assemblies and multi-color LED assemblies) that are independently controllable. This segmentation allows different regions of the light guide to receive different color combinations, enabling broad color space coverage while maintaining edge uniformity through selective activation and intensity control of individual assemblies.

Different LED assemblies are positioned at different locations along the light guide edge, with each assembly providing locally optimized color output. The multi-color LED assemblies contain multiple LEDs (red, green, blue) that can be independently controlled to achieve precise local color mixing, while white LED assemblies provide consistent illumination. This local quality control enables both broad color space and uniform edge lighting.

Multiple LED assemblies (both white and multi-color types) are merged into a single integrated strip configuration that interfaces with one light guide. This consolidation improves lighting efficiency by reducing optical interfaces and simplifying the overall structure, while the modular assembly design keeps individual components manageable despite the increased number of elements.

The LED strip assembly serves multiple functions simultaneously: it provides broad color space coverage through multi-color LEDs, maintains edge uniformity through distributed white LEDs, and achieves efficient light coupling to the light guide through its integrated geometry. This multi-functionality reduces the need for separate components, thereby improving lighting efficiency without proportionally increasing complexity.
