The applications of neon lamp
Most small neon (indicator-sized) lamps, such as the common NE-2, break down at between 90 and 110 volts. This feature enables their use as very simple voltage regulators or overvoltage protection devices. In the 1960s General Electric (GE), Signalite, and other firms made special extra-stable neon lamps for electronic uses. They even devised digital logic circuits, binary memories, and frequency dividers using neon lamps.Such circuits appeared in electronic organs of the 1950s, as well as some instrumentation. At least some of these lamps had a glow concentrated into a small spot on the cathode, which made them unsuited to use as indicators. These were sometimes called "circuit-component" lamps, the other variety being indicators. A variant of the NE-2 type lamp, the NE-77, had three parallel wires (in a plane) instead of the usual two. It was also intended primarily to be a circuit component.recommend directory: 3528 smd top led
Small neon lamps are used as indicators in electronic equipment. Called "tuneons" in 1930s radio sets, they were fitted as tuning indicators, and would give a brighter glow as the station was tuned in correctly. Larger lamps are used in neon signage. Neon lamps, due to their low current consumption, are used as nightlights. Because of their comparatively fast response time, in the early development of television neon lamps were used as the light source in many mechanical-scan TV displays. They were also used for a variety of other purposes; since a neon lamp can act as a relaxation oscillator with an added resistor and capacitor, it can be used as a simple flashing lamp or audio oscillator. (See Pearson-Anson effect.)
Neon lamps with several shaped electrodes were used as alphanumerical displays known as Nixie tubes. These have since been replaced by other display devices such as light emitting diodes, vacuum fluorescent displays, and liquid crystal displays. Novelty glow lamps with shaped electrodes (such as flowers and leaves), often coated with phosphors, have been made for artistic purposes. In some of these, the glow that surrounds an electrode is part of the design. recommend directory: 5050 led strip warm
In AC-excited lamps, both electrodes produce light, but in a DC-excited lamp, only the negative electrode glows. Thus a neon lamp can be used to distinguish between AC and DC sources and to ascertain the polarity of DC sources.
Indicator-sized lamps can also be filled with argon, krypton, or xenon rather than neon, or mixed with it. While the electrical operating characteristics remain similar, the lamps light with a bluish glow (including some ultraviolet) rather than neon's characteristic reddish-orange glow. Ultraviolet radiation then can be used to excite a phosphor coating inside of the bulb and provide a wide range of various colors, including white.A mixture of neon and krypton can be used for green glow, but nevertheless "green neon" lamps are more commonly phosphor-based. recommend directory: 5050 Smd Led strip light

What are pixie's and nixie's..part two...?
What are pixie's and nixie's..and what IC'S could drive them.
and what is striking voltage....?
I feel that the community chose the wrong answer to this question especially about IC's..
please dig deeper..
what IC's drove nixie tubes.....?..then you will understand..
not bad Edesigner..now name an ic that could drive a gn4-a nixie...5 stars involved---striking voltage 180 v
Pixies were actually vacuum tubes with a sort of base that allowed the pins to heat an element to a reddish glow and represent a number..oh they were state of the art in 1960 but in 1960 nobody even heard of an integrated ckt...They were driven by switching transistors with gate characteristics like the ECG123a,,,There were tons of power transistors and you could just go wild..However due to the current requirement an IC would need a pony ckt to carry the input (high amp) to the pixie ,,,if you have a bunch of these they are rather collectible i might add don't toss em out till you check,,,,,they were cute 1" high was a big one and 1/2" was pretty common...I had a Wang 3000 that had accuracy to 12 digits ..I used it to do truncated prismoidal formulas on earth cut fill projects...Pretty fancy for 1968 i must say...Also it was as bi as a suitcase...now i have a ti-89 fits in my pocket..don't we all love progress...Well that's what a Pixie was....Good luck from the E...
