  • Optical projection device for an icon display element
    Patent number: 9442354
    Abstract: A simple optical projection device with a high luminous efficacy has a point light source, a projection screen, a mask that is arranged in the light path upstream of the projection screen and is light-transmissive in some areas, and a light focusing optical lens arranged between the point light source and the mask. The optical lens is selected such that the prolongations of the emerging beams of the optical lens on the side thereof facing the point light source intersect in a virtual perspective center which is more remote from the lens than the point light source.
    Type: Grant
