The advantages of tungsten filament lamps are as follows:
(1) Tungsten filament bulbs can be widely used in various occasions because of their diverse light source forms, which can adapt to these environments. They also have different irradiation methods such as scattering and diffusion. Therefore, they are widely practical.
(2) The light emitted by tungsten filament lamps has a wide spectral range, that is, it can continuously produce a spectrum, and all exist in the form of visible light. This makes the stability of tungsten filament bulbs very good.
(3) The light color of tungsten filament lamps is very close to sunlight, so the color rendering is very good and it is not easy to cause visual errors. The spectrum is very uniform, so there will be no glare.
(4) Tungsten filament bulbs have good focusing performance. Because of their small light source, they can highlight the three-dimensional sense of objects. Therefore, in modern interior design, they are often used for three-dimensional design.
