Ordinary emitting diodes (LED lights) are only two tube feet, one long foot and one short foot, of which the long foot is connected to the power supply, and the short foot is connected to the power supply. Is there a LED light with four tube feet? There are really such RGBLED lights in the market. Since the two feet are enough, why have there four feet? The manufacturer will take you to further interpret it. Don't look at his four tube feet. In fact, there are three RGBLED lamps, one of which is the public part of three LED lights, and the other three feet are the second tube of each LED light. The lamp also has a common cathode and common anode. For RGBLED lamps with common anode, the long tube of the four tube feet is anode, that is, the positive electrode of the power supply. On the anode, the black table pen is exposed to any of the other three tube feet. If this LED light is normal, you will also see that this LED light is light, and the voltage drop will appear on the multimeter. Ordinary LED lights, the results of the presentation are not different. After the LED lamp is electric, the red light is emitted. If the red table is motionless, the black table pen is exposed to the other two tube feet, and you will find that there will be light of other colors. In addition to red and green and blue, this is why is it called it called The reason for his RGB LED light, where R represents red, comes from the first letter of the English word Red (Chinese meaning: red); G represents the green of the English word Green (Chinese meaning: green) the first letter; It is blue, from English word BLUE (Chinese meaning: blue) first letter. If you look at the pressure drop during the measurement process, you will find that different colors of light will be emitted, and the pressure drop will be different. From the picture above, you can also see. In practice, the light of these three colors is also the three primary colors of light. If the two colors of the LED lights are lit at the same time, the light of other colors can be emitted, such as the red and green LED lights to light up at the same time. When a LED light is lit at the same time, a compound light will be emitted: white light. The designed four -legged RGBLED lamp also has his benefits. After controlling these four tube feet, you can control the LED lights to send a variety of colors of light. Of course, it is definitely very troublesome to control it. Over. Of course, you can also detect the quality of the RGBLED light with this method. If you find that some colors (three types of red and blue) are found during the detection process, then the LED light that emits the color is likely to break down For individuals, it is not possible to repair it. It needs to be replaced. The manufacturer specializes in the production of RGBLED lamp beads, patch RGB, and plug -in RGB production.

Health-related and waterborne infections cost the world billions of dollars annually and thousands of lives yearly. One important preventive step is sterilization, which can be accomplished using various methods, including ultraviolet (UV) light irradiation. Since proper sterilizing procedures can stop the transmission of infectious diseases, this requirement has become more urgent because of the worldwide coronavirus epidemic.

Compared to semiconductor light sources, current sources like mercury bulbs are bulky, hazardous, and have fewer application options.

What Are UV LEDs?

UV-LEDs are LEDs that produce UV rays with wavelengths of 400 nm or less. They are separated into deep-ultraviolet LEDs (DUV-LEDs), which have an emission wavelength of around 200-320 nm, and near-ultraviolet light-emitting diodes (NUV-LEDs), which have an emission wavelength of about 320-400 nm.

UV-LEDs are promising candidates for several applications, including the replacement of UV lamps, fluorescence light sources for displays and lighting, good lighting sources for microscopes and exposure equipment,
light sources for chemical excitation 4used in biotechnology, medicine, and resin curing, excitation light sources for spectroscopy used in currency notes identification, DNA chips, and environmental monitoring, and sanitary light sources for disinfection and sterilization.

Creation Of Uv Leds

Even in an ongoing epidemic, disinfecting fomites is a crucial public health practice in halting the transmission of many infectious diseases. There is undoubtedly interest in creating technology that would allow for regular, high-throughput disinfection, especially in highly visited public venues, given the recent knowledge of the close role contact and indoor crowding play in virus transmission.

Despite their effectiveness, the active chemicals in traditional chemical disinfectants in clinical and laboratory settings pose climate, public health, and infrastructure risks that make their widespread deployment difficult. Additionally, the effectiveness of chemical disinfectants can vary depending on the user and how carefully they follow repeatable cleaning procedures. As an alternative, ultraviolet (UV) radiation has been widely utilized to inactivate numerous microorganisms, including viruses. Ultraviolet light can be automated to produce a repeatable germicidal dose.

The introduction of uv led diode gives the very same level of decontamination as the traditional mercury lamps, but with several advantages, including simplicity of retrofit in a variety of usual overhead light sources, with enhanced disinfection capabilities.

The effectiveness of UV for cleaning is shown by its straightforward mode of operation. While neighboring thymine bases (or uracil bases in the case of RNA) suffer dimerization, which disrupts the structure of nucleotide sequences and creates "roadblocks" in genome replication, adjacent nucleotide bases in DNA and RNA uniquely absorb UV photons

Researchers demonstrated the antiviral effectiveness of a uv led module by inactivating two viruses: the seasonal human Coronavirus 229E (hCoV-229E) and the immunodeficiency virus type 1 (HIV-1). Researchers demonstrate significant reductions in viral replication within seconds after UV-LED exposure by simulating common environmental instances of virus scattering (e.g., sneeze, cough, blood droplets) utilizing droplet dispersal approaches.

Our research contributes to the body of knowledge on using UV-LEDs to sanitize high-contact public places. UV-LEDs represent an extra, very effective layer of defense against pathogen spread because they are inexpensive and simple to install into a range of existing light fixtures, especially during an ongoing respiratory infections pandemic.

Requirements For UV-LEDs

Nine 275 nm LEDs in a 3 3 array and twenty 380 nm LEDs in a 4 5 array comprised the two sets of UV-LEDs that were supplied. The distance between the LEDs and the exposed sample was around 5 cm, and the UV light output from each array ranged from 0.4 to 0.6 mW/cm2.

The highest radiation duration was 30 seconds, and the combined arrays supplied a total dose to the radioactive samples ranging from 8 mJ/cm2 to 20 mJ/cm2. The device's entire lighted area was around 10 cm by 20 cm, or 200 cm2, significantly greater than the irradiated sample, and it received a total aquifer dose of 1.6 J to 4 J.

Results To The Research For the Development Of UV LED Under Epidemic

uv led module were shown in these studies to be effective at inactivating UV-resistant bacteria, HIV-1, and the human Coronavirus 229E. In the case of the human coronavirus, we saw a reduction in viral replication of up to 5.8-Log. Since RNA damage is the specific mechanism of deletion by UV irradiation and how-229E is an RNA virus, researchers predict a similar reduction in infectiousness after exposure to UV.

However, they did not directly assess if this reduction in hCoV-229E replication corresponds with a similar reduction in infectivity. Researchers warn that our results could be directly applied to assess the efficacy in sanitizing non-enveloped viruses because they are typically more resilient to UV than enveloped viruses.

In this study, investigations indicate that our selected virus designs were all enveloped viruses, selected to assess any possible differences in UV receptivity due to viral genome length.

The inactivation of B. pumilus spores, which are renowned for possessing a high level of UV resilience, was demonstrated in our trials. Researchers say this may be the first proof that non-enveloped viruses can be inactivated by UV light. It has been proposed to use B. pumilus spores as a stand-in for testing the inactivation of the non-enveloped human rotavirus by UV radiation.
