One of my first quality flashlights, the Romisen RC-29, has one of those white plastic reflectors.
Perhaps they are too specific to the flashlight to be sold as a generic part.
Was thinking of a very floody light but I guess a literal white plastic washer would fit the majority of the bill of having a LED hole and tidying up the background.
You could just remove the lens on these from Kaidomain and use the white plastic reflector: PMMA OPTICAL LENS
More along the lines of barely more than a LED behind a plain lens so I reckon a nylon penny washer (large OD compared to ID) is the easiest and cleanest way to do it.
They are very common and easy to get in assorted dimensions e.g. https://hw.menardc.com/main/items/media/RCSEM001/ProductXLarge/Washer_Plastic.jpg
For the Romisen RC-29, it is a reflector.
Maybe you're talking about something else.
Hmmm, if I read this correctly; it appears the Romisen RC-29 does not have a “reflector”.
According to that review, it has a "plastic magnifying lens" which I would argue acts as a reflector.
I would call it a reflector, and I think kreisler is confused.
Thank you for the detailed, easy to understand; explanation.
No arguments from me, I am simply trying to learn.
But I do not understand how a “magnifying lens” could also be a reflector?
Could you or someone please explain.
I own the 16340 size version of the Romisen RC-29. It’s not a reflector. The angle of the cup is below the angle of the emission cone from the LED. As such, it doesn’t really “reflect” much light.
If you take the cup out the output will look almost exactly the same. Neither the flood nor the spot will be any brighter. However, without it, in flood mode there may be slightly less diffuse light outside of the floodbeam’s circle. And in spot mode, you may get artifacts outside the spot beam caused by reflections off the bondwires.
The Romisen RC-29 definitely has a white plastic reflector.
I don't know about the 16340 version.
Can Raccoon City or someone please explain how a “magnifying lens” can be a reflector?
This does not make sense to me. I want to learn how this is possible.
Thank you.
kreisler called it a "plastic magnifying lens," but it reflects light and I think it's a reflector because of that fact.
Does your lens magnify Raccoon City??
Okay, I got confused.
There is a plastic magnifying lens, and that is completely separate from the reflector.
Sorry.
No problem, thank you; that helps my understanding.
Looks like a mule, only the white cup scavenges more side-thrown light and diffuses it forward(ish).
First seller didn’t ship, second seller did ship and then it got stuck in “customs” for a month.
Got this one: https://www.aliexpress.com/item/32947942168.html
Turns out the torches which go for this white thing are diving torches often with suggestions of providing photography light, and it’s probably no cheaper than an aluminium reflector because on opening this one up it’s a machined white plastic cup in about a 90 degree cone.
You get a big puddle of even light as a “mule” does except this is a factory design and it has something instead of nothing where a reflector would be. I suspect the cup and the distance from the lens is to force a tighter puddle while keeping the lack of hot spots. If you instead rammed the bare led up to the lens it would have an enormously wide puddle.
4 modes on twist switch does not feel good scrubbing the double o-rings back and forth. I’m going to pretend the other modes don’t exist and or stick a single mode driver in there.
So did you get the flashlight that you wanted?
There are several ways to get a diffused beam, such as using a frosted lens or TIRs. Not sure why you wanted a white cup vs a reflector, but it seems interesting.
I think it’s acted as a gasket, to keep the LED centered and to press the led board (MCPCB) to the pill/body so that it won’t fall off. Never seen those plastic stuff on any website for sale though.
