With the development of LED in UVC spectroscopy, LEDs can also be used for sterilization and disinfection in the future, replacing traditional UV lamps. LED bulbs can develop visible and invisible LED bulbs by adjusting the chip wavelength, among which UV LEDs become one of the development drivers of UV lamps due to lower overall cost. Industry experts estimate that the compound annual growth rate of the UV lamp market will reach 13.32% between 2017 and 2021. Traditional UV lamps have space and light limitations, require another lens to aid adjustment, and traditional UV lamps mostly contain mercury, while UV LEDs have a long life, small size, uniform light output and power savings, even at initial cost. High, but can save up to 50% of maintenance costs, which in turn reduces overall costs. Ultraviolet light is invisible light with a wavelength between 100 and 400 nm. It is widely used in sterilization, 3D printing, medical and curing technologies, and is widely distributed in the market. At present, the commercial development of UV LEDs is mostly from 365 nm to 400 nm. It belongs to the longer wavelength UVA spectrum and is used to cure adhesives. It is often used in consumer electronics and disposable medical products. With the development of LED in UVC spectroscopy, LEDs can also be used for sterilization and disinfection in the future, replacing traditional UV lamps. UVC LED instruments do not need to operate in an ozone environment, save power and miniaturization, and have higher freedom in product design. UVC LED lamps can be carried in the future, and can even be embedded in other devices, and can be disinfected in a few seconds. For laboratories or hospitals with small spaces, the area of ​​use and overall cost can be greatly reduced. However, the current UVC LED bulbs must first solve the problem of heat dissipation. At present, the conversion rate of UVC LEDs is only 5%, and the remaining 95% are converted into heat energy, which will cause the LED chips to overheat and fail, which will also damage their life and light output.
