Abstract

An apparatus for lighting or illuminating spaces, bodies or surfaces, which is formed from a plurality of light emitting diodes (1). The light emitting diodes (1) are radially enclosed by a casing body (14) which is adjoined at the end by a tubular element (15) which bears against a lens (4). A set spacing is thereby established between the light emitting diode (1) and the lens (4). All light spots issuing from the light emitting diode (1) are projected to form a single light spot of a high level of brightness by virtue of the superimposed relationship at a spacing in front of the lens (4).
