When mounting an overhead Far-UVC ceiling light with a ceiling height of 10 feet, there’s a 75% drop in light power from 1 Foot to 2 Feet, but only a 5% drop in light from 4 feet to 10 feet with only 1% of the light power available at floor level.
For those without an intense knowledge of advanced mathematics (or even very basic mathematics for that matter), something such as the inverse-square law can seem incredibly daunting.
There are equations with numbers and variables, references to physics, and many more things which quite frankly seem very boring. For that reason, we’re going to try to cover this in a very practical way, rather than a technical one, and offer tools and charts that will make it even easier for everyone. It can not be underscored enough how important it is to familiarize yourself with this basic mathematic principle to use the most cutting-edge bio-agent suppression method ever devised in human history – Far-UVC lighting.
The law itself, in AP-UVGI applications, using FAR-UVC light, applies to all lighting in general. It applies to any sort of electromagnetic radiation really. Its most relevant application here is germicidal irradiation using light wavelengths of between 207nm-230nm. This very narrow 23nm band of UV light was discovered as a small UV exposure window much safer for humans yet deadly to pathogens responsible for the current pandemic!
In a nutshell, it teaches how to use UV light as a weapon in the War on Flu! The inverse-square law teaches us how Far-UVC light works over distance and why the distance between your Far-UVC light source and your target area is so important when the amounts of Far-UV light reaching areas are paramount to the safety of people and the effectiveness of UVGI (Ultraviolet germicidal irradiation), or if adding Active Personal into the UV zone than, AP-UVGI, however just think of it as invisible light to keep things simple.
Let’s say we have a light source that is on full power and our bio-agent target is 1 foot away from it. If our target moves double the distance away from the light (2 feet), how much of the light’s power will reach it? The natural reaction is to think “half power” – but unfortunately that’s now how light works, all light, including germicidal Far-UVC light all follow the inverse-square law of distance.
According to the law, the power of the light will be inversely proportional to the square of the distance. So if we take a distance of 2 and square it, we get 4, the inverse of which would be 1/4 or rather, a quarter of the original light power – not half.
Moving our target 3 feet from the Far-UVC light source (3 * 3 = 9, so 1/9) the power of our Far-UVC light on the target now becomes 1/9th of what it originally was, and this is where time becomes a very important factor for effective germicidal irradiation and for the safety of active personnel in the Far-UV light disinfection zone over extended periods of time.
The below chart shows how the drops in light power work from one Far-UVC light mounted at a ceiling height of 300cm to the floor using a 20-watt 222nm excimer KrCl lamp properly bandpass filtered for a human-safe AP-UVGI application.
