Uv led development is in full swing, driving the UV lamp market

With the development of LED in UVC spectrum, LED can also be used for sterilization and disinfection in the future, replacing traditional ultraviolet lamps. LED bulbs can develop visible and invisible LED bulbs by adjusting the chip wavelength. Among them, uv led has become one of the drivers for the development of ultraviolet lamps due to its low overall cost. Industry experts estimate that the compound annual growth rate of the UV lamp market will reach 13. 2017 between 2021 and. 32. Traditional ultraviolet lamps have space and light limitations, requiring another lens to assist adjustment, and most traditional ultraviolet lamps contain mercury elements, however, uv led has long service life, small volume, uniform light output and power saving. Even if the initial cost is high, it can save up to 50% of the maintenance cost, thus reducing the overall cost. Ultraviolet rays are invisible light with wavelengths between 100 and 400nm. They are mostly used in sterilization, 3D printing, medical treatment and curing technologies and are widely circulated in the market. At present, the commercial development of uv led is mostly from 365 nm to 400 nm, which belongs to UVA spectrum with long wavelength. It is used for curing adhesives and is often used in consumer electronic products and disposable medical products. With the development of LED in UVC spectrum, LED can also be used for sterilization and disinfection in the future to replace traditional ultraviolet lamps. Uvc led instruments do not need to be operated in ozone environment, save electricity and are miniaturized, and have higher freedom in product design. uvc led lamps can be carried around in the future and even embedded into other equipment, disinfection can be carried out within a few seconds. For laboratories or hospitals with small space, the use area and overall cost can be greatly reduced. However, at present, uvc led bulbs must first solve the problem of heat dissipation. At present, the conversion rate of uvc led is only 5, and the remaining 95 are all converted into heat energy, which will lead to overheating and failure of LED chips, it also damages its life and light output.
