1. An annular-arranged lamp capable of backward projecting by concave sphere, in which two or more than two light emitting devices arranged in a circular or polygonal means being annularly installed at the side of annular heat dissipation device to be installed with light emitting devices of the lamp, the light projection axial line of each light emitting device is defined in a reverse direction which is 90 degree larger but 180 degree smaller relative to the preset final projecting direction for illuminating light of the lamp for projecting towards a reflection device with concave sphere disposed above the annular heat dissipation device, the project surface after being reflected by a concave spherical reflection unit of the reflection device with concave sphere is coaxial with the final projecting direction for illuminating light beams, light beams of the light emitting devices are reflected by the reflection device with concave sphere then refracted to a preset projection range, thereby forming a unified light source, and it mainly consists of:

  • Annular heat dissipation device (101);

    which is configured by an annular heat dissipation structure made of a heat conductive material, and combined with the reflection device with concave sphere (103), wherein the annular heat dissipation device (101) is provided with a side of annular heat dissipation device to be installed with light emitting devices (102) for the installation of two or more than two light emitting devices (110);

    The side of annular heat dissipation device to be installed with light emitting devices (102);

    which is defined at the inner side, upper side or an upward-inclined surface of the annular heat dissipation device (101) for the installation of two or more than two of the light emitting devices (110), for projecting light beams to a concave spherical reflection unit (104) of the reflection device with concave sphere (103);

    Reflection device with concave sphere (103);

    which is combined with the annular heat dissipation device (101), the top of the reflection device with concave sphere (103) is formed as a sphere, and the interior of the sphere is integrally formed with a concave spherical reflection unit (104) processed with a polishing or coating treatment, or a concave spherical reflection unit (104) having a high-performance reflection surface capable of being installed inside the top end of the reflection device with concave sphere (103) is separately manufactured to be assembled, the enclosure of the reflection device with concave sphere (103) is disposed at the top end and the periphery of the annular heat dissipation device (101), and the space defined between the annular bottom end thereof and the bottom end of the side of annular heat dissipation device to be installed with light emitting devices (102) is clamped with a light pervious protection sheet (111) through a fasten ring (112), and two sides of the light pervious protection sheet (111) are installed with elastic pads (113);

    Concave spherical reflection unit (104);

    which is constituted by a concave spherical reflection unit (104) integrally formed inside the reflection device with concave sphere (103) and processed with the polishing or coating treatment, or a concave spherical unit (104) having a high-performance reflection surface capable of being installed inside the top end of the reflection device with concave sphere (103) is separately manufactured to be assembled, and the concave spherical reflection unit (104) is equipped with a high-performance light reflection capability for reflecting the light beams from the light emitting devices (110) to the final projecting direction;

    The operations and functions of the assembly of the mentioned components are;

    the two or more than two of the light emitting devices (110) arranged in a circular or polygonal means are annularly installed at the side of annular heat dissipation device to be installed with light emitting devices (102) of the lamp, and the light projection axial line of each light emitting device (110) is defined in a reverse direction which is 90 degree larger but 180 degree smaller relative to the preset final projecting direction of the lamp for illuminating light beams, so as to project light beams to the reflection device with concave sphere (103) installed on the inner side, upper side or the upward-inclined surface of the annular heat dissipation device (101), then reflected by the concave spherical reflection unit (104) of the reflection device with concave sphere (103) to a projection surface, and for being coaxial with the final projecting direction for illuminating light beams, the light beams of the light emitting devices (110) are reflected by the reflection device with concave sphere (103) then refracted to the preset projection range, thereby forming a unified light source.
