About the Knowledge Lightbulb Book black outline icon
This icon shows an open book with a glowing lightbulb rising from its pages, surrounded by light rays. It represents knowledge, ideas and learning, making it a fit for e-learning platforms, study apps, library sites, teaching presentations and innovation or insight themed graphics.
The open pages form a wide base while the bulb and rays draw the eye upward, balancing the composition. It pairs well with graduation cap, pencil and brain icons; use it where a single strong symbol for learning or insight is needed.
This is the black outline version of the knowledge lightbulb book 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.
