LIGHT-EMITTING DIODE APPARATUS

摘要

The disclosed apparatus comprises a metal and glass support, and has as its source of radiation at least three different semiconductive crystals, which emit mono- or heterochromatic radiation of the optical spectrum. Said crystals are disposed on a common sublayer, which comprises a cavity with a flat bottom and a lateral surface reflecting the radiation and resembling the surface of a revolving element. The number of points of implantation for the crystals inside the cavity and the number of glass-insulated outlets correspond to the number of semiconductive light emitters. The body of the apparatus comprises a cover in the form of a semispheric lens with a cylindrical base having elongated prongs disposed so as to correspond with the positions of apertures contained in the sublayer. The space between the cylindrical base of the cover and the upper surface of the sublayer is filled with a sealing polymer compound, and the point at which each conductor is joined to the corresponding outlet is covered with a conductive layer of adhesive. With the structure proposed, the light-emitting apparatus is intended for use as an indicator during the modes of operation of various types of machines. Its brightness means it can also be used for illumination in place of an incandescent light.
