The UV LED does not comprise any hazardous metals that would be challenging to dispose of. UV LEDs produce significantly less heat than conventional light sources. UV LED lamps reach a maximum temperature of 40°C, while mercury lamps can reach temperatures of over 60°C. Radiative recombination results in the production of a single photon of light with an energy and wavelength (the two are related to each other by Planck’s equation) determined by the bandgap of the material used in the active region of the device. Non-radiative recombination can also occur where the quantum of energy released by the electron and hole recombination produces heat rather than photons of light.

This LED has an maximum intensity of 200 mcd, which means it’s just bright enough to get your attention but not quite flashlight bright. High Power UV LED module with 20pcss 6868, 9600mA&37V, 60 degree beam angle, Radiant power mW, 365nm / 395nm / 405nm available, ideal for UV Curing, etc. Ultra narrow beam angle of 7 degree, metal Can SMD package, UVC / UVB available, ideal for spectroscopy, inspection and medical, biological, chemistry etc.

The origin of the high ideality factor in AlGaN‐based quantum well ultraviolet light emitting diodes. The electroluminescence spectra under different injection currents are shown in Fig.4a. With the change of the injection current from 2 to 20 mA, no noticeable EL emission peak blueshift and full-width-at-half-maximum narrowing are observed. The EL emission wavelength is longer than what we expect, and the reason is being investigated. Figure4b shows the EL spectra measured with a UV–VIS spectrometer, intended to study the defect EL emission.

This technology, which uses UV LED to protect against contaminants and bacteria, is energy-efficient and will help reduce costs compared to existing UV lamps used in treatment plants. Government initiatives for implementing green curing technology, mainly in developed countries viz., the U.S. and Europe, will have a significant impact on the UV LED market demand. uv led diodes manufacturers and growing energy consumption will also positively affect product sales. In addition, the ability of Ultravoilet LEDs to kill harmful germs and viruses and growing interest in safety and security will accelerate the adoption of these LEDs in smart home appliances in developing nations. The unit for measuring luminous intensity is called the candela, although when you’re talking about the intensity of a single LED you’re usually in the millicandela range. The interesting thing about this unit is that it isn’t really a measure of the amount of light energy, but an actual measure of “brightness”.
