First Tests.
Purpose;
1. To find out the lowest operating power to fully illuminate the diode.
2. To test extreme low powerd heat.
Notes;
1. My Laser Bee is still not here so I can only guess the output of the diode.
2. My 12mm drillbit is not here so this test was done with no heatsink but for the copper module.
3. Items used were a 9mm 445nm diode set in a standard module with a 3 element lens, powered by a Mastech HY1802D.
4. I did not use the G-1 or G-2 as this was to test heat, not output.
5. New IR Thermometer is not here and I dont trust my old one I used my fingers on both sides of the diode.
6. This test was done continuously, only shutting down the power at the end.
7. Room temp is about 72F.
Outcome;
1. At just over 100mA @ 3.5V (5-10mW?) the diode does flicker into life, but is very dim, like a weak LED or so. Run at this setting for 3 minutes. Module still cool to the touch.
2. At about 150mA @ 3.6V the beam kicks on fully. It was very dramatic. Very Bright. Run at this setting for 3 minutes. Module still cool to the touch.
3. At 200mA @ 3.7V the beam is bright enough at 24" on a white wall to make it hard to look at directly. Ran it at this setting for 3 minutes, module still cool to the touch, maybe a tad less so.
4. A few steps later at about 300mA @ 3.8V the beam it self is visable in my sunlit room. Still getting brighter will each step. Ran at this setting for 3 minutes, the module felt neutral, not warm not cool.
5. At 400mA @ 4.0V I can clearly see the beam, Dot is very bright. I ran this setting for only a minute or less before I noticed movement near the focal point. Smoke. Smoke? My wall was smoking. I shut down the power. Tiny hole in my drywall. Up to that point the diode barely got warmer then my finger at about a minute into 400mA
Conclusion of test #1;
1. Diode works wonderfuly at low power.
2. Diode stays cool enough to run for at least 15+ minutes under 400mA with no heatsink (further testing to come as this one was cut short)
3. Dont point lasers as things that can burn. Unless you want them burnt.
