Guys, I'm restarting my project from 2012 finally and I have run into a problem. LEDEngins were "hot" at that time and I bought a 10W RGBW and the heatsink from TCSS. Not sure why I got 8.7 collimator lens with a holder but it was probably the better option.
But they don't go together well. Not sure how many of you are using these LEDs now but if you do and perhaps those that did back then, what was the solution to fix the holder with lens in place and is there perhaps a sweetspot with regards the distance of the lens from the LED?
Here's a picture of what I have
Lens holder diameter is too small and it has plenty of room to move inside the heatsink module. And it doesn't sit well on the LED either so I don't like just screwing everything together tight.
If I take the holder off then the lens itself sits OK on the LED but I'm not sure that's the best idea possibly because of the heat and because I'm not sure if that's the best position for the lens to be to get a nice beam of light which I imagine is important for good blade illumination.
Tried searching the forum but nothing good really came up. Would appreciate a comment or two. I can probably 3D print my custom holder but again, what's the best position for the lens? Not that there's a lot of room but a couple of millimeters for sure.
