  • Patent number: 7400450
    Abstract: A light-splitting device includes a power module, a transmission module and a filter module. In this case, the power module has a rotating component and a first connection component. The rotating component connects with the first connection component. The transmission module has a second connection component and a third connection component. The second connection component connects with the first connection component. The filter module has a filter element and a fourth connection component. The fourth connection component is disposed on one side of the filter element and connects with the third connection component. When the rotating component and the first connection component rotate, the first connection component drives the rotation of the second connection component and the third connection component, so that the third connection component drives the rotation of the fourth connection component and the filter element.
