About the Knowledge Lightbulb Book color 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 colour outline version of the knowledge lightbulb book icon: the same line drawing in an accent colour, useful for highlighting a state, a category or a brand tone without adding visual weight.
