There are significant differences between barium tungsten electrode short arc xenon lamps and sodium lamps in multiple aspects:
The working principles of barium tungsten electrode short arc xenon lamp and sodium lamp are different
Barium tungsten electrode short arc xenon lamp
Its working principle is to apply high voltage power to the two poles of the lamp tube, which excites the gas and generates arc discharge, thereby generating high-temperature plasma and emitting strong light radiation. The barium tungsten electrode is a crucial component of the short arc xenon lamp, providing stable and efficient electron emission.
Sodium lamp
Also known as sodium vapor lamp, it is an electrical light source that uses sodium vapor discharge to generate visible light. After the light bulb is activated, an arc is generated between the electrodes at both ends of the arc tube, causing the sodium mercury inside the tube to evaporate and become sodium vapor. The electrons emitted from the cathode collide with the discharge material during its movement towards the anode, causing it to gain energy and generate ionization excitation, thereby releasing light radiation.
The light source characteristics of barium tungsten electrode short arc xenon lamp and sodium lamp are different
Barium tungsten electrode short arc xenon lamp
It has advantages such as high brightness, high color rendering, and long lifespan. Its radiation spectrum is close to sunlight, with a color temperature between 5000 and 6000 K and a color rendering index of over 94. In addition, it can also start instantly and be easy to maintain.
Sodium lamp
Emitting golden white light, it has the advantages of high luminous efficiency, low power consumption, long lifespan, strong fog penetration ability, and no insect attraction. Among them, the color of the high-pressure sodium lamp is better than that of the low-pressure sodium lamp, because the vapor pressure of the discharge material in the high-pressure sodium lamp is high, and the number of collisions between electrons and sodium atoms is frequent, which widens the resonance radiation spectrum and produces radiation from other visible spectra.
The application fields of barium tungsten electrode short arc xenon lamp and sodium lamp are different
Barium tungsten electrode short arc xenon lamp
Due to its high brightness, high color rendering and other characteristics, it is suitable for movie projection, photography, train locomotives, and simulating sunlight. In addition, it is also widely used in medical, industrial, military and other fields.
Sodium lamp
Commonly used for road lighting, floodlighting, square lighting, etc. Its orange light has strong and soft transmission in foggy weather, which can improve the visibility of the road surface. Therefore, it is commonly used in traffic arteries and artificial lighting to reduce traffic accidents.
In summary, there are significant differences between barium tungsten electrode short arc xenon lamps and sodium lamps in terms of working principle, light source characteristics, and application fields.
