LIGHT-EMITTING DIODE MATRIX AND METHOD FOR MAKING SAME

摘要

The invention concerns a light-emitting diode matrix device for obtaining high light intensity as well as peak luminance, and the method for making same. Thus, said array comprises light-emitting diodes (2) incorporated in packaging housings (1) made of moulded resin whereof the planar upper surface (5), forming an optical output window (6), receives a bonded hemispherical glass or plastic lens (11), with identical or substantially identical index to that of the resin, such that said window (6) is located at a specific distance from the emitting surface of the semiconductor component (2) so that said emitting surface is proximate to the object Weierstrass point of the spherical diopter thus formed by said hemispherical lens (11). More particularly, the light-emitting diode housings (1) are soldered by surface-mounted component process, on an electronically powered support card (9) and the free space between said housings (1) is coated with a jointing paste.
