Light light source noun any device serving as a source of illumination. A light source with reflectors that projects a beam of light in a particular direction. Generally a source of light can be considered a point source if the resolution of the imaging instrument is too. Light comes from different sources called light sources.

So the source converts electrons to photons and the detector converts photons to electrons. A light source essentially is an optical transmitter that is paired with an optical receiver both of which are connected to electrically based devices or systems. In mathematics a point source is a singularity from which flux or flow is emanating. These types of light are naturally occurring and do not necessarily need humans to create light.

Although singularities such as this do not exist in the observable universe mathematical point sources are often used as approximations to reality in physics and other fields. A source of light makes light. Our main natural light source is the sun. Other sources include fire stars and man made light sources such as light bulbs and torches.
