UV-C LED Lighting for a Package Disinfection Application
I’m looking for UVC light strips for an application which is a box that holds packages. The box is 22"x14"x15" and the smallest package will be 5”x5”x2”. The box has a lid at the top. Assumed exposure time can be 10 min. I’d like to know the following:
-Do you have any recommendations regarding the amount and layout of LE D strips recommended for this application? I’m only looking for a rough estimate. We will do our own validation for this.
-Do you have the irradiance pattern on your website in excel so we could manipulate it for our specific application?
-I want to confirm you do not require a LED regulator board (i.e. the LED strips can be directly connected to a regulated power supply)
-Is any heatsinking of the LED strips required?
Based on the dimensions of the box, it appears that the farthest distance from the box side surface to the disinfection surface will be 10 inches (5"x5"x2" box placed in the center of the box, 22 inches wide).
As such, I would imagine that the 10-inch distance would be a good starting point for referencing the exposure dosage values, which are shown below (unfortunately only available in PDF format):
The exposure dosage at 10 inches and 5 minutes of exposure time show 61.5 J/m². Extrapolating to 10 minutes would provide 123 J/m². While different pathogens have different levels of susceptibility, we believe that this would be a good starting point in terms of being "in the ballpark" for sufficient exposure.
Our ability to provide extensive support in the design and layout is somewhat limited, but I would imagine that having the UV-C LED strip lights on each side of the box (5 total?) would be necessary as some "shadowing" could otherwise occur.
The LED strip lights are constant voltage 12-volt DC devices that do not require any special controllers. Even a simple 12-volt DC battery would be sufficient to operate it.
No heatsinking is required.
