A light diffuser is described having a body with an opening therethrough defined by an inner wall. Light conducting paths are disposed through the body and couple to the opening. The inner wall is sloped at an angle to reflect the light onto a workpiece. The size of the opening and the height of the diffuser above the workpiece determine the angle of the inner wall.
