UVC LED Chip are light emitting diodes in the ultraviolet C spectrum ‌

• ‌ Definition ‌ : UVC LED (Light Emitting Diode) refers to a light emitting diode capable of emitting ultraviolet C spectrum (wavelength between 200nm and 280nm).
• ‌ application ‌ : Because of its strong sterilization and disinfection ability, UVC LED lamp beads are usually used in disinfection, air purification and water treatment and other fields.
• ‌ advantage ‌ : Compared with the traditional UVC mercury lamp, UVC LED is smaller, does not contain mercury and other harmful substances, and is safer and more environmentally friendly.
• ‌ selection criteria ‌ : high quality UVC LED lamp beads should have wavelength accuracy, high luminous intensity, high efficiency and long life, good thermal management, appropriate packaging and protection, through the relevant certification and good brand reputation ‌.

What is the disinfection effect of UVC LED Chip ?

• Efficient sterilization ‌ : The ultraviolet light emitted by UVC LED lamp beads can effectively kill bacteria and viruses in a short time, and the sterilization efficiency is much higher than that of traditional methods. Experiments have proved that it can successfully kill more than 99.9% of harmful bacteria, such as E. coli, Staphylococcus aureus ‌.
• ‌ widely applicable ‌ : The bactericidal effect of UVC LED chip is not limited by the types of microorganisms, bacteria, viruses and other microorganisms have no resistance to ultraviolet rays ‌.
• ‌ Safety and environmental protection ‌ : UVC LED chip do not contain mercury and other harmful substances, the use of the process will not produce secondary pollution or residue, safety to human body and the environment ‌.
• ‌ advanced technology ‌ : UVC LED chip is a new third generation semiconductor light source, compared with traditional mercury lamp, in environmental protection, high efficiency, precision, energy saving and safety has a number of advantages ‌.

How long is the life of UVC LED Chip?

• Life range ‌ : The life of UVC LED chip is usually within a certain range, which varies according to different products and technical levels. Generally speaking, the service life of UVC LED lamp beads can reach ‌3000 hours ‌ or more, and some high-quality products can even reach 5000 hours to 10000 hours ‌.
• ‌ Compared with traditional mercury lamp ‌ : Compared with traditional mercury lamp, UVC LED chip have a longer service life. The service life of traditional mercury lamps is about 1000 hours, and the service life of UVC LED lamp beads is several times or even tens of times ‌.
• ‌ Influencing factors ‌ : The life of UVC LED chip  is affected by many factors, including oxygen impurity content, driving current, operating temperature and switching times. Reducing oxygen impurity content and reasonable control of driving current and other working conditions help to extend its service life ‌.

What is the working temperature of the UVC LED chip ?

• Working temperature range ‌ : The working temperature of UVC LED lamp beads is usually affected by a variety of factors, but in general, the appropriate working temperature range is roughly between 20℃-40℃. In this temperature range, the UV radiation intensity of UVC LED lamp beads is the largest and most stable, and the sterilization and disinfection effect is better ‌.
• ‌ The importance of heat dissipation design ‌ : because the UVC LED lamp beads will generate heat during the working process, if the heat dissipation design is poor, it will greatly affect the life of the lamp beads. Therefore, the module structure design is usually based on the principle of heat dissipation priority, and the junction temperature of the LED chip needs to be controlled below 85 degrees Celsius to ensure the stability and durability of the lamp beads ‌.
