1. A method for detecting forensic evidence comprising:
- accessing a semiconductor forensic light that has a handle, a plurality of light heads attachable to and detachable from said handle, each of said light heads being capable of emitting a light of different wavelength than another of said heads, at least one of said light heads including a semiconductor light emitting device that can emit light of a wavelength useful in detecting forensic evidence, and a primary heat sink to which said semiconductor light emitting device is affixed, said primary heat sink serving to draw heat away from said semiconductor light emitting device, and at least one light exit on said light head, said light exit being sized and shaped to permit light to exit said light head for use in detecting forensic evidence, placing said semiconductor forensic light in a physical location where forensic evidence is expected to be discovered, actuating a switch on said handle to cause a light beam to be emitted by said semiconductor forensic light, causing said light beam to shine on an area that may contain forensic evidence, observing a contrast between forensic evidence in said light beam and the background where it rests.

Abstract
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.
