US Patent 6954270 Method for detecting forensic evidence

A semiconductor forensic light is disclosed. The forensic light may use a variety of semiconductor light sources to produce light that contrasts forensic evidence against its background for viewing, photographing and collection. Example semiconductor light sources for the forensic light include light emitting diodes and laser chips. A heat sink, thermoelectric cooler and fan may be included to keep the forensic light cool. A removable light source head may be included on the forensic light to provide for head swapping to give the user access to different wavelengths of light.
