1. A light source arrangement, comprising:

  • an electric input adapter for electrically connecting with a power source;

    a light head, which comprises;

    an elongated supporting frame, which is made of good heat conduction material, having a first end, an opposed dissipating end, and a peripheral surface extended from said first end to said dissipating end; and

    a transparent light shelter sealed on said peripheral surface of said supporting frame, wherein said light shelter has a spherical shaped light projecting portion projected from said peripheral surface of said supporting frame; and

    a luminary unit, which is arranged to be protected by said transparent light shelter and comprising;

    a circuit provided on said peripheral surface of said supporting frame and electrically connected with said electric input adapter, and a plurality of luminary elements spacedly mounted on said peripheral surface of said supporting frame align therewith and to electrically connect to said circuit for emitting light, wherein when each of said luminary elements emits said light in a radial direction with respect to said supporting frame, said supporting frame is adapted for transmitting heat from said luminary element at said dissipating end of said supporting frame; and

    a heat dissipating member mounted at said dissipating end of said supporting frame to directly dissipate said heat generated from said luminary unit by means of heat transfer,wherein said circuit has a through guiding window, wherein when said circuit is printed on said peripheral surface of said supporting frame, said luminary element is mounted at said peripheral surface of said supporting frame within said guiding window to electrically couple with said circuit.
