Since I have easy access to the LED's in my module and it may become necessary
in the thread "Let's take this shitty led apart and let's design a better one!"
to change the broken ones out, and I wanted to try to measure the current and
just play with it, I turned on my soldering iron and garbed my solder sucker and removed it.
Watching the LED closely I remembered I had bought a cheap USB microscope in Aldi
some years ago, so my thought was lets see what we can see, and to my surprise
it worked out well, the USB micro cam is not worth much with it's 320x240 resolution,
but by putting my phone's camera up to the eyepiece and holding it frustratingly steady
it was possible to take some clear focused shots.
This was my first view ever of a power LED up close like that, quite exciting stuff to do when you stoned.
Taking a peep:
LED Module: With the Red test LED missing:
Dusting off the ALdi USB Microscope literately:
A peek down the scope with 16x4 magnification and using my mobile to take pictures:
Increasing the magnification to 16x10:
Making a Chart:
The next thing I wanted to do was make a chart over the current voltage relationship
in the LED that's in my grow light, I don't know the LED brand, and if it's a noname or
BridgeLux. Anyway here is the numbers.
Setting up the LED test bench:
The finished result a chart of current voltage relationship,made manual in Open Office Draw, my life's first !
Note: I have named the LED in the the chart - Epistar - BridgeLux but I have no way of knowing if that's the case.
When using the microscope and taking the measurements I almost wished I had a white coat and
a clipboard to the notes, I'm like fuck I'm doing science now,
My conclusion is: Nice to see the LED under the microscope and see it's not a mess,
the chip it self and the wire mesh looks perfect(from a layman perspective)
and the current-voltage relationship points to a almost linear rise with no surprises along the way.
