The application standard of tungsten wire in medical halogen lamp is mainly based on its unique physical and chemical properties, as well as the special requirements of medical lighting equipment for light sources. The following is a detailed analysis of the application standards of tungsten wire in medical halogen lamp:
- Physical property requirements
High melting point:
The melting point of tungsten wire is as high as 3410℃, which is much higher than the working temperature required by general lighting equipment, which enables tungsten wire to work stably for a long time at high temperature without melting easily.
High strength:
Tungsten wire has high strength and can withstand certain mechanical stress and vibration, ensuring the stability of the light source of medical halogen lamp during use.
Good conductivity:
Tungsten wire has excellent conductivity and can quickly generate heat and emit light after power is turned on, meeting the needs of medical lighting equipment for instant response to light sources.
- Chemical property requirements
Antioxidation:
Tungsten wire is not easy to react with oxygen in the air at high temperature, and has good antioxidation properties, thereby extending the service life of medical halogen lamps.
Corrosion resistance:
Tungsten wires have strong corrosion resistance to a variety of chemicals and can maintain stable performance in harsh environments such as humidity and corrosive gases.
- Special requirements for medical lighting
Light spot concentration:
Medical halogen lamps usually require concentrated light spots and high brightness so that doctors can clearly observe lesions during surgery or diagnosis. Tungsten wires are used as light sources, and their light points are concentrated, making it easy to form the required light spots.
Low power consumption:
Medical equipment usually has strict requirements on energy consumption. Tungsten halogen lamps can maintain low energy consumption while providing sufficient brightness, which meets the energy-saving requirements of medical equipment.
Adjustable irradiation angle:
Medical halogen lamps are usually equipped with devices that can adjust the irradiation angle to meet the needs of different surgical or diagnostic scenarios. The structural design of tungsten halogen lamps should facilitate the adjustment of the irradiation angle, and the stability of the light source should not be affected during the adjustment process.
Safety:
The safety of medical equipment is of paramount importance. Tungsten halogen lamps should comply with relevant safety standards, such as explosion-proof and electric shock-proof, to ensure the safety of doctors and patients.
