Which symbol represents a light fixture in blueprints?

A light fixture is commonly represented in blueprints by a circle or ellipse with lines emanating outward. This symbol effectively communicates the function of the light fixture, as the lines suggest illumination spreading from the fixture, indicating that it is a source of light. The use of circular or elliptical shapes is a standard practice in electrical and architectural drawings, making it easily identifiable for anyone reviewing the plans.

The shape and lines convey clarity regarding the location and purpose of the light fixture in the overall design. In contrast, the other choices do not align with conventional symbols used in blueprints for light fixtures, as they each represent different elements or do not effectively symbolize lighting arrangements. Understanding these symbols is crucial for accurately interpreting electrical blueprints and ensuring proper installation and functionality of lighting systems.
