About the Knowledge Lightbulb Book color filled 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 colour filled version of the knowledge lightbulb book icon: a flat, solid-colour shape that stands out in dashboards, marketing pages and app tiles where the icon needs to carry colour meaning.
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.
