Abstract
The invention relates to an array of light generators where each light generator comprises reflecting collimation optics in the form of curved mirrors for collimating light emitted by light sources such as surface mounted Light Emitting Diodes. The collimation optics is formed to collimate light in a direction parallel with a plane, e.g. a printed circuit board, onto which the light sources are mounted. The light sources may emit light parallel with the direction of collimation or non-parallel, e.g. perpendicular, with the direction of collimation in which case the collimation optics redirects the light rays from the light source. The array of light generators can be used in combination with a television display for creating a pixelated image appearing to the viewer as an image peripherally surrounding the display.
