  • Patent number: 9711490
    Abstract: An illumination device includes a supporting base, at least two supports and at least two semiconductor light emitting elements. The supports are disposed on the supporting base and coupled to each other. The semiconductor light emitting elements are respectively coupled to the supports. The semiconductor light emitting element includes a transparent substrate and a light emitting diode (LED) structure. The transparent substrate has a support surface and a second main surface disposed opposite to each other. The LED structure is disposed on the support surface. At least a part of the light emitted from the LED structure may pass through the transparent substrate and emerge from the second main surface.
