About the Knowledge Lightbulb Book black filled icon
This icon pairs a glowing lightbulb, its rays fanning out in short diagonal lines, with a closed book drawn in a thick wedge shape below it. Together they represent knowledge, ideas, and learning, making it useful for e-learning platforms, course cards, blog headers, and training presentations.
The bulb sits centered on the book's spine with a bracketed filament base and light rays on both sides, while the book's angled edge suggests stacked pages. It pairs well with education, brain, and study icons; use it where 'knowledge' or 'insight' needs a visual anchor.
This is the solid black filled version of the knowledge lightbulb book icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
