About the Knowledge Book Light Bulb black filled icon
An open book with two curved pages and a visible spine sits at the base, and a light bulb rises out of its center with short rays fanning out around the glass and a ridged screw base below. Together they say learning turns into insight, so it works for e-learning platforms and course catalogs, library and research pages, tutorial and knowledge base headers, training slide decks, and innovation or R&D sections.
The mark is vertically stacked: bulb and rays fill the upper half, the wide book anchors the lower half, and the bulb base overlaps the pages to lock the two elements together. The rays widen the outline, so allow extra padding around it. Pair it with book, brain and graduation cap icons. Use at 40px and up to keep the ray gaps open.
This is the solid black filled version of the knowledge book light bulb icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
