| 12. A high intensity light source arrangement, comprising:
a luminary unit comprising a luminary circuit, at least a terminal electrically connected to said luminary circuit, and at
least a luminary element electrifying with said terminal for emitting light;
a heat dissipation unit, wherein said luminary circuit is provided on an outer surface of said heat dissipation unit to support
said luminary element and to dissipate heat generated from said luminary unit;
a base housing which comprises an electric input connector electrically connected to said luminary unit; and
a converging element which comprises a light housing for enclosing said luminary unit and a plurality of lens ring integrally
formed on a peripheral wall of said light housing, wherein each of said lens rings is inclinedly extended at a diffraction
angle for diverging a light beam from said luminary element to form a collimated light beam.
