U.S. Pat. No. 4,727,648 (Savage) allegedly cites a “circuit component such as an electrical unit is mounted to a circuit board, by providing a mounting body to support the unit on the board; providing conductive means including contact structure with spring fingers to receive a nit terminal, the conductive means including auxiliary terminal means to project outwardly of the body via a body slot, the contact structure and auxiliary terminal means defining a bridge portion with tab means in the body slot to anchor the body. The light unit may extend at either end of the body.” See Abstract.
U.S. Pat. No. 4,781,960 (Wittes) allegedly cites an “indicator light, preferably a LED, is mounted in a insulating housing secured by a pair of legs with relatively broad feet which are soldered to conductive pads on the surface of a printed circuit board. Preferably, the printed circuit board uses ‘surface mount’ technology. The leads of the LED are spot welded to the legs to make electrical connections between the LED and the circuit board. The structure elevates the LED above the board surface, and/or allows mounting the LED close to the edge of the circuit board, and/or allows the light from the LED to be directed parallel to the board surface. A particularly advantageous use of the structure is one in which printed circuit boards are arranged in an array with the boards parallel to one another and the LED mounting structures near the end of each board so as to provide maximum visibility of the LEDs from many angles so as to quickly indicate equipment functional status to an operator or trouble-shooter. In the manufacturing method, the leg structures are stamped and formed along the edge of a pre-plated and selectively solder-coated strip, with prongs being formed on each leg. The prongs then are pushed into recesses in a plastic body. The LED is inserted and the leads are spot welded to the legs. Then, the assembly is broken off of the strip along a previously formed break-line.” See Abstract.
U.S. Pat. No. 6,386,733 (Ohkohdo) allegedly cites a “light emitting diode mounting structure for a light emitting diode having four leads has two metal plates fixed to wire on a housing. The leads engage the metal plates in electrical contact therewith and are supported by the metal plates, a surface part of which reflects light from the light emitting diode. See Abstract.
U.S. Pat. No. 6,583,542 (Nagano) allegedly cites a “device for mounting a light source according to the present invention is composed of an electric lamp unit (21) having a baseless electric lamp (7) and a base member (8) and a mounting unit (9) having a cavity for receiving the base member of the electric lamp unit (21). The base member (8) is composed of a cylindrical body having a cavity for receiving a lower part of the baseless electric lamp (7) and supporting a pair of lead wires (7a, 7b) led out of the baseless electric lamp (7) on its outer surface. The mounting unit (9) includes a pair of conductive contact members (10a, 10b) on an inner surface of the cavity, which are connected at their lower ends to connection terminals (12a, 12b) on a printed circuit board (12). The electric lamp unit (21) is fitted into the mounting unit (9) in a removable fashion.” See Abstract.
U.S. Pat. No. 4,623,206 (Fuller) allegedly cites “a spring battery retainer that is used to secure a small ‘coin’ or ‘button’ battery to a printed circuit (PC) card or the like. Use of the spring battery retainer provides for positive location of the battery, inexpensive electrical contacts for the battery terminals and positive spring compression that is necessary to insure hard contact with the cathode and the anode terminals of the battery. The battery is easily installed and removed by slightly lifting one end of the battery retainer and sliding the battery in or out. A bend in the spring battery retainer provides sufficient hold-down pressure so that the battery makes reliable contact with an electrical pad located on a PC board. The spring battery retainer is inserted into the PC card and then soldered to it in much the same way as a standard electrical component such as a resistor. The dimensions of the spring battery retainer can be varied so that coin or button batteries of various sizes can be securely fastened to a PC card.” See Abstract.
