About the Knowledge Bulb Open Book black filled icon
An open book with curved pages sits on a flat cover, and a light bulb with radiating rays rises from its center where the spine falls. Together they read as reading that sparks understanding, which makes the design useful for e-learning platforms, course landing pages, tutorial and help sections, training presentations and library or research materials.
The bulb sits high enough that its rays clear the page tops, and the book is drawn symmetrically so the whole mark balances on a single vertical axis. It works alongside graduation cap, brain and notebook icons from the education set. At small sizes the short rays can be trimmed without losing the idea.
This is the solid black filled version of the knowledge bulb open book icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
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.
