Portable ultraviolet device for exploring mineral resource

A portable ultraviolet device for exploring a mineral resource, the portable ultraviolet device comprising:

• a body having a sealed first central inner space and two lateral second inner spaces opened downward and mutually spaced from each other with the first inner space there between;
• a visible component coupled to the body to pass through the body so that the mineral resource disposed at a lower portion of the body is observed from an upper side of the body;
• an ultraviolet lamp assembly coupled to the body to emit ultraviolet rays onto the mineral resource, wherein the ultraviolet lamp assembly comprises:
• a first ultraviolet lamp assembly inserted into one of the two second inner spaces and being coupled to the body and a second ultraviolet lamp assembly inserted into the other of the two second inner spaces and being coupled to the body, wherein the first ultraviolet lamp assembly comprises a first ultraviolet lamp extending in a first direction, a downwardly opened first receiving container rotatably coupled to the body about a first rotation axis parallel to the first direction to receive the first ultraviolet lamp, and a first ultraviolet filter coupled to an opening of the first receiving container, and the second ultraviolet lamp assembly comprises a second ultraviolet lamp extending in the first direction, a downwardly opened second receiving container rotatably coupled to the body about a second rotation axis parallel to the first direction to receive the second ultraviolet lamp, and a second ultraviolet filter coupled to an opening of the second receiving container;
• a first power supply received in the first inner space;
• a first printed circuit board received in the first inner space to transmit power from the first power supply to the first ultraviolet lamp;
• a second power supply received in the first inner space;
• a second printed circuit board received in the first inner space to transmit power from the second power supply to the second ultraviolet lamp;
• and
• a darkroom component coupled to a bottom surface of the body to surround the visible component and the ultraviolet lamp assembly, the darkroom component defining an external light blocking space having a selectively openable inlet in a lower portion of the body.
