385 Nm UV LED 40W - How Effective Are LED Blacklights?
The 385 nm uv led 40w is a great way to add some fluorescent glow to your Halloween setups.385 nm uv led 40w These are very inexpensive and easy to find at most any major discount store. The efficiency of UV blacklights varies from product to product, so be sure to check the details on the specific LED strip or bulb you are considering buying. Ideally, you should stick with products that indicate their efficiency on their specifications sheet so that you can compare the wattage needed to achieve your desired effect. Otherwise, you can use the quick lookup table below to help determine how much UV light is needed for a given space.
Using a high-quality LED chip set, this 40W UV curing light emits UV radiation from the top and the bottom of its body.385 nm uv led 40w This ensures a uniform and even distribution of UV energy across the entire surface of the module, making it ideal for use in printing applications where precise UV exposure times are required for bonding or curing. Additionally, the module’s built-in cooling system helps prevent thermal degradation and enhances its longevity.
In the mainstream UV market, 365nm UVA LEDs are the standard because they emit a narrower spectrum than traditional mercury vapour lamps.385 nm uv led 40w These wavelengths are used to irradiate special glues and adhesives, triggering the polymerization reaction that causes them to cure. Many of these glues and adhesives have their UV requirements listed on the data sheet, and it is often implied that the material needs to be exposed to 365nm light in order to cure.
Studies have shown that UVA LEDs can disinfect surfaces with up to 3 W/m2 irradiance at workplace height for 8 hours each day, while still being safe for humans.385 nm uv led 40w This is the same as the level of irradiance that you get from the sun when you walk outside on a sunny day and will kill viruses like COVID-19 very quickly.
Unfortunately, there are no LEDs that produce a pure, focused dose of UVC. Even the smallest amount of UVC is dangerous to bacteria, and that is why UVC Hg lamps will continue to be limited to small professional applications for sterilisation and disinfection of surfaces.
With the advent of UVA LEDs, this may change, and the technology will eventually replace all UVC Hg bulbs. These will be based on the same basic semiconductor structure as the current generation of UV LEDs, but with much higher UV output and more focused on the 365nm – 395nm range of the visible spectrum. That will open up a wide range of new UV applications, including the safe disinfection of hospitals and medical environments. This could even revolutionize the treatment of the COVID-19 pandemic by enabling the safe and rapid disinfection of large areas in hospital rooms. It is a very exciting prospect.
