Hi guys, I’m not sure if I’m in the right place or not so if I have done this improperly please be nice but definitely correct me
I can’t find a place for homemade lamps, I am planning to mount an XHP70.2 directly to a natural convection heat sink with an interface board by sinkpad (direct thermal path, MCPCB copper). I want a pretty wide and very smooth beam, I will use this lamp to study with. I know it’s a bit overkill but I want to use this led for various reason (incredibly low resistance from junction to solder point for instance).
Mostly I find that Big Throw is what is the “objective” for on here, but I want the opposite as I need a nice study/desk lamp.
Can I just use some some kind of wide, shallow metal (Al) orange peel reflector and mount it to…. something?
Hmm… to me desk lamps are better with a large frosted bulb or wide flouro bar to create a ‘soft light’. A single point emitter will create stark contrasting shadows anytime your hand or something gets between the light and the desk/paper. So I would opt for a shallow, heavily stipled reflector, white (non silver) reflector or even some kind of diffuser in front of the led.
Just my thoughts. Take it with a grain of salt You’ll be the one using it
This is what i’m looking to do, perhaps I will go with an S3 host and just attach the head to the heatsink with jb-weld kwik set, using an Orange Peal reflector and possibly put a diffuser lens in front of it. I’ll still need to address the bright diffuser being visible but I might think of something or find something someone else did and sort of adapt it to my lamp. I want the lamp to be pleasant to use even if you are not ‘into lights’. I like the idea of multiple wide angle lights, I definitely do not want hotspot of any kind so the diffuser lens sounds good to.
You could build your lamp with the LED shining away from you, toward a (preferably white or stippled) surface, with the surface “reflecting” the light back to what you’re lighting. A lot of area lanterns use this method. Photographers do it too. You don’t need anything like a “real” reflector, just a white surface.
You’ll be the one using it
