MINE HEAD LAMP Russian patent published in 2019 - IPC F21L4/02 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the field of electrical equipment, in particular to the individual lighting equipment, used primarily for tunnels, mines, and mine workings illumination. Mine head lamp with storage battery power supply includes housing, two LED light sources with reflectors, control electronics unit and the light sources control body, which is brought out to the housing outer surface. First light source is installed at the parabolic reflector focal point. Second light source is installed in the reflector with the surface scattering structure and a shape providing the light flux direction downwards relative to the parabolic reflector axis at an angle of 30–60°.

EFFECT: technical result consists in both the distant objects and the near space good illumination provision and, the simultaneous far and near illumination possibility, obtaining the near space wide angle illumination, which minimizes the illumination dependence on the head position, and eliminates the “restless ray” problem.
