Cultural Context
The light bulb as a symbol for ideas dates back to early 20th century comics and cartoons, where characters would have a bulb appear above their heads during moments of insight.
As energy-efficient LED bulbs replaced traditional incandescents, the emoji has remained visually tied to the older technology due to its stronger symbolic association.
The phrase 'a light bulb went off' (or 'on') is commonly used to describe sudden realizations, directly connecting to this emoji's primary meaning.
In knowledge economy workplaces, this emoji serves as a digital marker for intellectual contributions and creative input in group discussions.
