TīmeklisThe tungsten filament lamp temperature is about 2800–3300 K and consists of a linear double-ended quartz tube containing a tungsten filament, which is resistively heated. The quartz tube heats up to 400°C or more and … TīmeklisA tungsten filament lamp when first switched on results in a relatively gradual increase in illumination from the filament, which can take up to 250 ms to reach full brightness. …
TīmeklisIn a directly heated cathode, the filament is the cathode and emits the electrons. In an indirectly heated cathode, the filament or heater heats a separate metal cathode electrode which emits the electrons. From the 1920s to the 1960s, a wide variety of electronic devices used hot-cathode vacuum tubes. TīmeklisThe filament in a light bulb is made of a long, incredibly thin length of tungsten metal. In a typical 60-watt bulb, the tungsten filament is about 6.5 feet (2 meters) long but only one-hundredth of an inch thick. The tungsten is arranged in a double coil in order to fit it all in a small space.
