UVC LEDs YouTube Video


Recommended Posts

Its hard to say if he has UVC based on his tests with an apple, not a green banana and the lack of any deep peak. Either his spectrometer isn't sensitive at 265nm or has some bk glass blocking less than 300nm or his fibers are cheap glass.

But he might just have junk for leds. They were really cheap, after all.

After watching the video all I learned is that even if I assume these to be true 265nm leds, the visible leakage isn't any advantage over a Mercury bulb.

He bought separate LED components and mounted them on suitable metal PCBs with footprint patterns matching the LED cases.

Power LEDs are tiny for the thermal power they must dissipate.

They must be mounted on a metal-type carrier PCB that must be mounted on a heatsink or cooling device big enough to remove the generated thermal losses.

 

I am considering buying a hotplate like this for minor general electronics rework. I might even use it some day to mount LEDs.
