Abstract

A non-glare screen is assembled of prismatic rings stacked one on the other and coaxially enclosing a light emitting surface. Each ring has a cross-section of a right triangle. One leg of the triangle is perpendicular to the axis of the light emitting surface and the hypoteruse forms with the one leg an angle between 35 DEG to 45 DEG , preferably 40 DEG .
