Multi-wave-domain lamp

Abstract

The invention provides a multi-wave-domain lamp. The multi-wave-domain lamp comprises a base and a lamp head detachably connected with the base. The base comprises a base body, an operation unit capable of inputting a predetermined operation order, an arithmetic unit capable of converting the operation order into a control signal, and a control unit arranged in the base body. The lamp head comprises a shell, a base plate and a plurality of light source units. Each light source unit is provided with a sleeve part, a light emitting diode light source and a lens. The light emitting diode light sources emit light with the predetermined wavelength coverage to the outside through the lenses via light ray emitting outlets. The control unit makes at least one light emitting diode light source emit light with predetermined intensity according to the control signal.

Description

technical field [0001] The invention relates to a lamp, in particular to a multi-wave domain lamp used for criminal identification. Background technique [0002] In the field of criminal forensics, lamps with different wavelength ranges are widely used to collect relevant physical evidence, such as fibers, shooting remnants, body fluids, teeth and bone fragments, bite marks and scars. At present, forensic personnel carry a forensic box equipped with various light source pens with multiple light-emitting wavelength ranges including purple light, blue light, green light, red light, infrared light, and ultraviolet light at the evidence search site. Take evidence. [0003] And the process of adopting the many light source pens configured in the forensic box to carry out the process of evidence collection for the forensic personnel, not only has to often search for specific ones in the forensic box in response to the needs of different physical evidences to be collected in use. ...

[0003] And the process of adopting the many light source pens configured in the forensic box to carry out the process of evidence collection for the forensic personnel, not only has to often search for specific ones in the forensic box in response to the needs of different physical evidences to be collected in use. The trouble caused by the light source pen, and when conducting field investigations, the forensic personnel need to deliberate on the properties of the specimen, experimentally and frequently change the light source pen test of different wavelengths such as purple light, blue light, green light, red light and infrared light. Specimens, in the process of repeatedly changing the light source pen for testing, it not only consumes time but also reduces the work efficiency of forensic personnel
