The so-called tungsten filament lamp, it is a kind of lamp made of tungsten wire, tungsten lamp belongs to the incandescent lamp. We use the tungsten wire to make the incandescent lamps. When the lamp is in the case of electricity, it will produce some heat, so it makes the lamps to achieve a certain incandescent state. In the end, use the radiation effect of heat to produce the light source that we can see. This is the so-called tungsten filament lamp.
Through the introduction of the above, we all know that the tungsten lamp belongs to the species of incandescent lamp. Therefore, tungsten lamps must also have the corresponding characteristics of incandescent lamp. Now SANHUI will introduce the specific characteristics of tungsten filament lamp.
1. The wide spectral range of tungsten filament lamps. That is to say, our tungsten lamp after the power can produce a continuous spectrum, we have with a spectrophotometer, which in this spectral range is a form of visible light, and the spectral range is between 400 to 780nm.
2. The light source of a tungsten filament lamp has a variety of forms, the use   range is wide. Tungsten filament lamp made by tungsten wire, a source of light it emits in the energized after the orientation, and it also has the light source diffusion, scattering and other irradiation form, and it has a wide utility range.
3. The color rendering of tungsten filament lamp is very good. That is to say, incandescent light emitted by the light source is very similar to the light of the sun.  Therefore, its color after the power is better, spectrum is relatively uniform, does not appear the phenomenon of glare and so on.
4. The light source of tungsten filament lamp is relatively small. Tungsten lamp is a type of lamp with a wide use range. What's more, its source is very small, but the spotlight is very good, so it often used to strengthen the role of the object field stereo feeling.
