About the Lightbulb Filament Rays black filled icon
A classic incandescent bulb sits at the center: a round glass dome, a two-loop filament inside on a straight stem, a ribbed screw cap below and eight short dashes radiating outward to show that it is lit. The visible filament and rays make it read as a spark of insight rather than plain lighting. Use it for idea boards, tips and hints panels, innovation slides, brainstorming apps and energy-saving pages.
The circle of the dome dominates the frame, balanced by the narrow horizontal bands of the base; the rays sit at even angles and keep the composition symmetrical. It sits well beside brain, rocket and gear icons in the same library. Keep the rays only at 32px and above - below that, drop to the bulb alone.
This is the solid black filled version of the lightbulb filament rays icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
