What term describes a source of light?

The term "lamp" is commonly used to refer to a source of light that typically includes a bulb or light source and is designed to provide illumination in a space. A lamp can incorporate various types of light sources, such as incandescent, fluorescent, or LED bulbs. The key characteristic of a lamp is that it is a device meant to be used primarily for the purpose of lighting.

While "bulb," "projector," and "LED" are all related to sources of light, they represent more specific components or types of lighting rather than serving as a general term for a source of light. A bulb is the part that emits light but is not a complete device. A projector is an apparatus that casts light onto surfaces to display images or videos, and an LED (Light Emitting Diode) is a specific type of light source that can be used in a lamp or other devices. Therefore, "lamp" accurately encompasses the broader concept of a light source.
