Abstract: A display incorporating light-emitting diodes, comprising a reflector which is formed in a holder. A light-emitting diode is mounted in the holder and projects into the reflector through an opening. The light-emitting diode is attached in the opening with the diode walls snugly abutting against the edges of the opening. The invention also relates to a method of manufacturing the display comprising light-emitting diodes and an installation to perform the method. Each diode is provided with two connections protected by the holder. The holder consists of surface-treated sheet metal, preferably anodized aluminum. The reflector is bowl-shaped and semispherical. Owing to the reflector a bundle of aligned beams of light is emitted from the light-emitting diode.
