Abstract
A flexible light path guide device includes at least one light path coupling member for receiving at least one visible light and at least one flexible optical guide member having a first end, a second end extending in a direction away from the first end, a light path positioned between the first and second ends and at least one chamber positioned in the light path in adjacency to the second end. The first end is coupled with the visible light corresponding to the light path coupling member. The visible light is guided by the light path to the chamber. The chamber guides the visible light to outer side of the flexible optical guide member. Accordingly, when the visible light reaches a projected object, the effects that the visible light has high brightness and low optical energy loss and the total volume of the projection imaging device is minimized are achieved.
