Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
125 words
An improved display comprising light-emitting diodes, a plate for mounting said light-emitting diodes, dish-shaped reflectors formed in said plate, the improvement comprising openings formed in said plate, the diodes mounted in said openings with the diode walls arranged in tightly abutting relationship against edges of said openings to form a mechanical bond between said diodes and said plates, said diodes having a cross-sectional dimension increasing toward a rear portion to ensure that said diodes are securely wedged to said plate when mounted therein and adhesive furher strengthening said mechanical bond; connections in the form of rods, said rods interconnecting said diodes and extending parallel and spaced some distance from said plate of the display; a filler compound, said diode connections covered by said filler compound.
Claim 2
Dependent Claim
125 words
An improved display comprising light-emitting diodes, a plate for mounting said light-emitting diodes, dish-shaped reflectors formed in said plate, the improvement comprising openings formed in said plate, the diodes mounted in said openings with the diode walls arranged in tightly abutting relationship against edges of said openings to form a mechanical bond between said diodes and said plates, said diodes having a cross-sectional dimension increasing toward a rear portion to ensure that said diodes are securely wedged to said plate when mounted therein and adhesive furher strengthening said mechanical bond; connections in the form of rods, said rods interconnecting said diodes and extending parallel and spaced some distance from said plate of the display; a filler compound, said diode connections covered by said filler compound.
Claim 3
Dependent Claim
147 words
An improved display comprising light-emitting diodes, said display comprising means for mounting said light-emitting diodes in a desired arrangement, said mounting means comprising a plate having integrally formed dish-shaped reflectors provided thereon and said reflectors having openings formed therein, said diodes being mounted in said openings with diode walls arranged in tightly abutting relationship against edges of said openings to form a mechanical bond between said diodes and said dish-shaped reflectors, said diodes having cross-sectional dimension increasing toward a rear portion cooperating with said mechanical bond to ensure that said diodes are securely retained in position with respect to said dish-shaped reflectors, adhesive means operative to strengthen said mechanical bond, connections in the form of rods, said rods interconnecting said diodes and extending parallel and spaced some distance from said mounting means of the display; a filler compound, said diode connections being covered by said filler compound.
