Lighting system for spotlights and the like

The lighting system for lighting apparatus for providing an intensive and uniform illumination in an area of a given size and at a given distance, consisting of:

• a light source for emitting light rays and generating a light flux;
• an auxiliary mirror having a first optical axis;
• a main mirror having a second optical axis;
• and
• a raster lens having a third optical axis with converging optical elements defining a first plurality of vertexes directing the light rays into a selected plane to create a light spot;
• wherein a reflecting area of said main mirror is created as a raster of concave mirrors each having an optical axis converging with respect to the second optical axis where the concave mirrors define a second plurality of vertexes having a shape of a rotational conic section with an axis of rotation identical with the second optical axis the concave mirrors being aligned with the second optical axis, said light source, and the auxiliary mirror, each of the concave mirrors having a particular reflecting area with a focal length and projecting light rays from the light source to the first plurality of vertexes of corresponding converging optical elements of the raster lens, said converging optical elements directing the projected light rays into the plane of the light spot, and
• wherein the first optical axis lies along the second optical axis and that the light rays are directed in an imaginary plane defining a directed light field and in a direction of the second optical axis by every concave mirror of the main mirror, said imaginary plane being perpendicular to the second optical axis
• where said each of said concave mirrors having a size, a shape, and a plurality of side walls, and all of said concave mirrors having the same size and shape where said side walls tightly abut each other, each of said lenses having a size and a shape, and all of said lenses having the same size and shape and abutting tightly to each other by their side walls, and the shape and size of each particular lens of the raster lens corresponds to a shape and size of the directed light field, and where each concave mirror directs light from the light source to geometrically correspond to a location of said concave mirror in the main mirror.
