Abstract
Angular momentum conservation and phase space are used for an exact calculation of bend loss in rectangular light pipes without rayiracing. It is found that the loss fraction ofrays in the bend plane is greater than that of the full 3-D distribution for any bend radius. There is excellent agreement between the calculated and measured loss.
