Abstract: A double-prism assembly is disclosed, including a first prism and a second prism arranged in a coaxial manner, wherein the first prism has a first prism face structure, the second prism has a second prism face structure, and the first prism face structure and the second prism face structure are arranged in a same direction or in different directions. For the double-prism assembly, when a beam of light hits the bottom of the first prism, passes through the first prism face surface and the second prism face surface, and comes out of the double-prism assembly, two circles of spots arranged in a coaxial manner may be formed, with equally distributed spots, and each of the two circles of spots can freely rotate clockwise or anticlockwise, greatly increasing the style and effect of the spots, and enriching the stage effect and rendering effect. In addition, it is simple in structure and low in cost. A multi-prism combinatorial structure and a light fixture are also disclosed.
