Claim:
1. An optical diffuser apparatus, for use adjacent a light engine in a lighting fixture for producing desired color-mixed light output, comprising: a first diffuser panel; and a second diffuser panel connected to the first diffuser panel; wherein the first diffuser panel includes a first end and a second end, and the second diffuser panel, in being connected to the first diffuser panel, is connected to the first diffuser panel at a portion of the first diffuser panel that is intermediate the first end and the second end of the first diffuser panel; wherein the first diffuser panel and the second diffuser panel are configured and arranged so that, when the apparatus is positioned for operation within the fixture, light emitted by the light engine at greater than a pre-determined threshold angle with respect to a centerline of the engine will pass through both the first diffuser panel and the second diffuser panel, thereby mixing colors of the light toward the desired color-mixed light output.
