Answer:

A cold light source is external illumination for microscopes or spectroscopes. Due to the greatly reduced infrared content of the light, the sample is hardly heated. This is important for living biological samples that would be killed by the heat of the halogen lighting.

for example, the light from a Bunsen burner, a standard light bulb or an electric cooker when hot.
