Abstract
The utility model discloses a court scientific physical evidence photographing area source irradiator, relating to a physical evidence photographing light source and solving the problems that conventional area source irradiators are inconvenient to use. The area source irradiator comprises a pedestal, a built-in power supply, a universal holder, and an area source. The built-in power supply is a rechargeable lithium battery mounted inside the pedestal. The area source is a square light source formed by multiple LED light sources which are mounted on four edges inside a square box and connected with the lithium battery. A white light softening plate is arranged in the front end of the area source. The square box is fixed on the top of a universal bar of the universal holder. The irradiator is equipped with the antiskid pedestal so that the irradiator can be stably disposed on a flat object. When a physical evidence is photographed, the area source irradiation position and angle can be adjusted at will, and the irradiator is convenient to use. The irradiator is provided with the built-in lithium battery so that the irradiator can meet work requirements of various extreme environments. The area source is in uniform in irradiation light so that a planar uniform light spot is formed on the surface of a photographed smooth trace, thereby improving the sharpness of imaging and displaying of the physical evidence of the trace and being beneficial for improving the evidence collection quality.
