The annular-arranged lamp capable of backward projecting by concave sphere provided by this invention is mainly provided with a side of an annular heat dissipation device being installed with light emitting devices (102) wherein the lamp is installed with two or more than two light emitting devices (110) arranged in a circular or polygonal means, and the light projecting axial line of each light emitting device (110) is projected towards a reflection device with concave sphere (103) disposed above the annular heat dissipation device (101), light beams of the light emitting devices (110) are reflected by the reflection device with concave sphere (103) then refracted to a preset projection range, thereby forming a unified light source. |
