Introduction to the difference between tungsten lamp and dysprosium lamp

Dysprosium lamps have very good light efficiency and better color rendering than other lamps, and are extremely bright, with a color index exceeding 80 and even a light efficiency exceeding 75lm. Tungsten lamp is easy to understand. An incandescent lamp with tungsten filament as wick, of course! But also can be used as a light source in the near infrared region! Many people don't know much about it! Let Bian Xiao tell you today! Bian Xiao here tries to explain the difference between tungsten lamp and dysprosium lamps, and carefully chooses the best two lamps, which will definitely bring peace of mind to your life.

Tungsten lamp is an incandescent lamp made of tungsten wire. Tungsten lamp can produce continuous spectrum, which is used in the visible spectrum region of 400 ~ 780 nm. Used as visible light source in spectrophotometer. Its spectral effective area can be extended to 3μm, so it is also used as a light source in the near infrared region.

Edison began the experiment of transforming arc lamp in 1877, and put forward the idea of dividing current to turn arc lamp into white light. The experiment should reach a satisfactory level. It is necessary to find a substance that can burn to white heat as a filament, and can withstand high-temperature combustion of more than 2000 degrees 1000 hours. At the same time, the usage should be simple, can withstand the impact of daily use, and the price should be low. It is also necessary to turn on and off one lamp without affecting the turn-off of any other lamp and maintain the relative independence of each lamp.

Dysprosium lamp is a kind of high intensity gas discharge lamp. It is a new gas discharge light source with high luminous efficiency (above 75lm/w), high color rendering advantage (above 80 color index) and long service life. This is a metal halide lamp. It uses dysprosium iodide, thallium iodide, mercury and other substances to emit its unique dense spectrum, which is very close to the solar spectrum, thus improving the luminous efficiency of the lamp.

The difference between dysprosium lamp and tungsten lamp simply tells you the difference between them: The color temperature of dysprosium lamp is about 5600, of course, it will fluctuate up and down, because the bulb is aging or something! But they are all around 5600K! The color temperature of tungsten lamp is 3200K! This is their biggest difference! It is easy to understand that dysprosium lamp is white light and tungsten lamp is yellow light! If you are a modern drama, you use less tungsten lamps and more dysprosium lamps! Tungsten lamp is frequently used in costume dramas, so as long as it is an evening drama, tungsten lamp is usually used! Then there are different models, subject to the lamps of ARRI:

Dysprosium lamps include: 200 W, 575 W, 1200 W, 2500 W, 4000 W, 6000 W,12000 W. There are also new PAR lamps, which also belong to dysprosium lamps, 200 PAR, 575 PAR, 65438.

Tungsten lamps include: 150W, 300W, 650W, 1000W, 2000W, 5000W, 24000W, etc.

Characteristics of tungsten lamp:

1: Advantages

Incandescent lamps have low power and low power consumption, which is very cheap; It has many forms, such as orientation, scattering and diffusion. It has a good lighting effect. Strong versatility and various colors.

2. Deficiencies

Incandescent lamps have a short life. Compared with other energy-saving lamps, under the same brightness, the power consumption of fluorescent lamps is a quarter of that of incandescent lamps. With the emergence of various energy-saving lamps, incandescent lamps consume more electricity.

Some characteristics of incandescent lamp

Incandescent lamp owner? It consists of glass shell, filament, conductor, induction column and lamp holder. The glass shell is made of heat-resistant glass to isolate the filament from the air. The filament is much thinner than the hair, and the conductor plays a connecting role. The sensing column is connected to the glass housing. It plays a role in fixing metal parts. Finally, the air in the glass shell is pumped away through the exhaust pipe, and the lower end is welded and sealed. Then the filament is electrified and heated to incandescent state, and emits visible light through thermal radiation.

Tungsten lamp specifications:

standard

Brand features and uses:

WB00 1: Good winding performance, no sagging, suitable for ordinary incandescent lamps, double or triple spiral fluorescent lamps, holiday lamps, support wires, etc.

WB 150: Good high temperature resistance and excellent processability, suitable for halogen lamps and spiral incandescent lamps.

WB584: High recrystallization temperature and good sag resistance at high temperature, suitable for special lamps such as impact-resistant filament and high color temperature filament.

Do you know more about tungsten lamps and dysprosium lamps through Bian Xiao's introduction? They can be used as additives, magnetic substances for refrigeration and, of course, storage materials. This is a biological effect lamp. And its life is increased according to the length of its tungsten wire! It was invented by Edison, and it has a unique response to the whole world. The above is the main content that Bian Xiao brought to you today, and you can buy it in a targeted way. I hope Bian Xiao's introduction today will help you!
