About the Knowledge Book Light Bulb black outline 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 black outline version of the knowledge book light bulb icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
