Claim Text:
1. An illumination device, comprising: a supporting base having a symmetrical center; and a plurality of semiconductor light emitting elements disposed on the supporting base and around the symmetrical center; and a plurality of supports disposed between the plurality of semiconductor light emitting elements and the supporting base, wherein the plurality of semiconductor light emitting elements are respectively disposed on one end of the supports; wherein each of the semiconductor light emitting elements comprises: a substrate, having a support surface and a second main surface disposed opposite to each other; and a plurality of light emitting diode (LED) structures disposed on the support surface of the substrate, wherein at least a part of light directly emitted from at least one of the LED structure directly inserts into the substrate through the support surface and emerges from the second main surface, so as to provide bidirectional light emitting function of the semiconductor light emitting element; wherein the plurality of semiconductor light emitting elements is tilted corresponding to the supporting base for decreasing shadow of lighting effect.
