The tungsten lamp is incandescent lamp made of tungsten wire as a filament.Tungsten wire lights can produce continuous spectrals for 400-780nm visible spectral area.As a visible light source in the spectrophotometer.The effective area of ??its spectrum can be extended to 3 μm, so it is also used as a light source in the infrared area.
How much tile lamp
The bottom of the old tungsten filament bulb "pear -shaped" is 220V40W, which is 40 watts
Principles of tungsten lamp
Edison began a test of reforming the arc light in 1877, and proposed that it was necessary to engage in a distributed current.This experiment must reach the degree of satisfaction.It is necessary to find a kind of substance that can burn to white heat for filament. This kind of filament must be burned over 2,000 degrees and one thousand hours.At the same time, the usage should be simple, can withstand the daily use, the price is low, and the lightness and extinguish of a lamp must not affect the lightness and destruction of any other light. Keep the relative independence of each lamp to choose this light.
Different from tungsten filament lamps and lanterns
The tungsten lamp is incandescent lamp made of tungsten wire as a filament.Tungsten wire lights can produce continuous spectrals for 400-780nm visible spectral area.As a visible light source in the spectrophotometer.The effective area of ??its spectrum can be extended to 3 μm, so it is also used as a light source in the infrared area.The lamp is a high -strength gas discharge light, which is a new type of gas discharge light source with high light effect (above 75LM/W), high color rendering (color index above 80). It is a type of metal halide lamp.It uses the charged iodine, iodide sub -tadpoles, mercury and other substances to emit its unique dense spectral spectrum. The spectrum is very close to the sun spectrum, which greatly improves the lighting efficiency and color rendering of the lights.
What is tungsten lamp
The so -called tungsten filament lamp, it is a type of lamps made of filaments using tungsten wires as lamps. Tungsten wire lamps are one of the incandescent lamps. We use tungsten wire to make incandescent lamps.It will generate a certain amount of heat below, so that the lamp will reach a certain state of idiot, and finally use the radiation effect of calories to produce the light source we can see, which is what we call tungsten wire lamps.The specific characteristics of tungsten wire lamps are shown below: 1. The spectral range of tungsten wire lamps is relatively wide.In other words, our tungsten lamp can continue to generate spectrals continuously. From the perspective of our light meter, it is still a visible form in this spectrum range. Its spectral range is from 400 to 780nm from 400 to 780nm.between.2. The light sources of tungsten filament lamps have various forms and are widely used.The tungsten filament lamp made of tungsten wires is a directed light source after power -on, and its light source also has a variety of irradiations such as mania, scattering, etc., and the practical range is wide.
Invention of tungsten lamp
In the first half of 1880, Edisons white hot light test was still no result, and even his assistant was discouraged.One day, he tied a bamboo silk on the edge of a banana fan in the laboratory to tear the filament, and made a filament after charcoal.The invention of white heat lights -bamboo silk electric lamp.This kind of bamboo silk has continued for many years.In 1904, Austrian Alexander Jackte and Franz Naman stood on the basis of their predecessors, and repeated experiments in the laboratory finally invented the worlds first tungsten silk lamp.
