2. Bi-pin lamp base - Wikipedia

   en.wikipedia.org/wiki/Bi-pin_lamp_base

   The suffix after the G indicates the pin spread; the G dates to the use of Glass for the original bulbs. GU usually also indicates that the lamp provides a mechanism for physical support by the luminaire: in some cases, each pin has a short section of larger diameter at the end (sometimes described as a "peg" rather than a "pin" [2]); the socket allows the bulb to lock into place by twisting ...

3. Lightbulb socket - Wikipedia

   en.wikipedia.org/wiki/Lightbulb_socket

   A wedge base holds the lamp by spring compression in the socket. The lamp is inserted and removed without twisting. Wedge base lamps are widely used in automotive applications, and many Christmas lights strings use plastic wedge-based bulbs. Other wedge bases include strip lamps, sometimes called architectural lamps, with S14s connections ...

4. List of LM-series integrated circuits - Wikipedia

   en.wikipedia.org/wiki/List_of_LM-series...

   LM393 differential comparator manufactured by National Semiconductor. The following is a list of LM-series integrated circuits.Many were among the first analog integrated circuits commercially produced since late 1965; [1] some were groundbreaking innovations [opinion].

5. Wedge base - Wikipedia

   en.wikipedia.org/wiki/Wedge_base

   (The wedge bases are now usually not even supplied with the bulbs, which cost nearly as much as buying a new set, typically 10 bulbs for a dollar but a new set of 100 for two dollars.) Modern sets typically have a long and thin wedge that extends all the way down to the back end of the socket, separating the two electrical conductors and ...

6. Gainclone - Wikipedia

   en.wikipedia.org/wiki/Gainclone

   The fully insulated TF model LM3886. A power opamp or audio opamp chip such as the National Semiconductor LM1875, LM3875, LM3886, or LM4780, which is a dual LM3886. A physically very short feedback loop. Miniaturised construction with short path lengths throughout the circuit. Minimal extra components, usually of high quality.

7. Incandescent light bulb - Wikipedia

   en.wikipedia.org/wiki/Incandescent_light_bulb

   Incandescent light bulbs consist of an air-tight glass enclosure (the envelope, or bulb) with a filament of tungsten wire inside the bulb, through which an electric current is passed. Contact wires and a base with two (or more) conductors provide electrical connections to the filament.
