A compact, portable illumination device designed to attach to a mobile telephone, often utilizing a spring-loaded or pressure-based mechanism. These typically employ LEDs to provide a supplementary light source for improved image and video capture. An example would be a small, rechargeable unit secured to the top edge of a smartphone to enhance visibility during a video conference.
Such devices address the limitations of integrated mobile phone flash systems, offering a more consistent and diffuse light. This results in better color rendering and reduced harsh shadows in photographs and videos. Their advent has facilitated improved content creation quality, especially for social media and professional applications, providing a simple and effective solution to suboptimal lighting conditions.
