The use of ultraviolet lamps and xenon lamps
The equipment is used to simulate the sun, ultraviolet radiation, temperature, humidity, condensation, rain and other comprehensive climate conditions, and observe the analysis of the changes in materials. It is widely used in aerospace, aviation, electronics, electrical, chemical and other products .
Definition of xenon lamp
Xenon lamps were originally developed for applications in the field of photography, but in recent years, people have turned their attention to applications in the field of UV curing. Xenon is a gas, so it can be used as a continuous light source or a pulsed light source. As a continuous light source, its xenon arc is essentially continuous, with low ultraviolet output and high infrared range. In the pulsed xenon flash lamp, the UV output is increased due to the increased gas pressure and the plasma temperature rise. The temperature in the plasma zone is proportional to the square root of the current density and the tube diameter.
Definition of UV lamp
Ultraviolet is Ultraviolet, referred to as UV, and UV lamp is referred to as UV lamp. Among them, according to the different wavelength bands, UV-A, UV-B, and UV-C have different
Uses: UV ultraviolet lamps are widely used in industries such as bamboo and wood floors, furniture, decorative materials, printing, iron cans, plastic coating, signs, circuit boards, optical discs, etc .; ultraviolet lamps are also used for bonding semiconductors, electronic components, liquid crystals, etc. Ideal light source for curing.
1. Ultraviolet wavelength: 290nm ～ 400nm
â‘ The luminous spectrum energy of UVA-340 tube is mainly concentrated at the wavelength of 340nm
â‘¡The luminous spectrum energy of UVB-313 tube is mainly concentrated at the wavelength of 313nm
â‘¢ The luminous spectrum energy of UVC-365 tube is mainly concentrated at the wavelength of 365nm
2. Lamp selection:
â‘ The UVA-340 lamp is recommended for most tests, it is to simulate the situation after summer noon sunlight, this lamp has an emission peak at 340nm.
â‘¡If the test needs to accelerate the aging rate, it is recommended to use UVB-313 type lamp, this lamp has an emission peak at 313nm.
â‘¢If the test for sterilization results is required, it is recommended to use UVC-365 type lamp, which has an emission peak at 365nm.
The life of the ultraviolet lamp generally refers to the time that it can maintain enough energy to operate, during which the energy gradually decay until it is below the acceptable range. In general, the standard UV lamp can emit enough UV energy for 800 hours.
