Lighting in Mobile Phone Cases
Mobile phone case lighting systems must operate within strict dimensional constraints while addressing multiple use cases - from selfie illumination to UV sanitization. Current solutions typically add 2-4mm of thickness to devices and draw 0.5-2W of power, presenting challenges for thermal management and battery life in everyday use.
The fundamental challenge lies in integrating additional lighting functionality without compromising the case's primary protective role or significantly impacting device ergonomics.
This page brings together solutions from recent research—including retractable lighting assemblies, UV-C sanitization systems, optimized lens arrangements for flash compatibility, and smart lighting control systems. These and other approaches focus on practical implementations that enhance device functionality while maintaining durability and user comfort.
