There are examples use here. Torches for the surveillance of the site SLDlaser removed. But they reach many kilometers ⊠The first EDC offersâ Acebeamâ:http://www.acebeam.com/w10.
I have done research which suggests a laser phosphor system could get much higher than 300cd/mm^2, but have done no real world tests yet due to the high cost of lasers as well as the danger to the eye.
In the future I will definitely be exploring that option, but it was just not something I wanted to put into this light.
The goal for this was LED only
I donât really consider the laser phosphor technology an LED.
Thanks
Great idea, I will work on a comparison of different lamps.
I also have to add some stuff to the optics comparison, stuff like multi-lens is missing.
I have designed a focusing system that is very precise, some spring-loaded screws can be turned to move the entire reflector forward and backwards by fractions of a millimeter
You will see in the renders I post soon.
Thanks
Yeah I was surprised when I heard about that W10 getting such high lux from such small diameter.
Laser+phosphor may be the future for high intensity!
Thanks! I haveât shows any of the real work yet since I want to post all of the preliminary stuff first like parts list and renders, but I have begun working on the physical thing.
If I can find a compact 30-50A driver that fits in the light I will mod it with a CFT90.
Currently the only drivers I have found that can do that run on 120/240VAC.
I do agree the beam brightness will be much more impressive even if I get less throw.
Worst case scenario I will mod it with an XHP70.2 and see how it performs
For now I just need to get the thing built first haha
Too large to fit inside the light, unfortunately.
I only have a few cubic inches of space due to how compact everything is inside.
When the light is finished, if there is no 30-40A driver out yet I will contact Lexel and see if he can custom build one for me.
Youâre correct, LED cooling is very important but also hard to do when the LED is floating in front of the reflector and trying to block the least amount of light possible.
It is liquid cooled
Iâll post the parts list tonight and renders tomorrow.
If I used the Synios DMLN31.SG I might have been able to get away with simply using heatpipes or directly attaching it to the aluminum, since it only uses 4W.
The higher temperature will probably reduce the candela though, even if it doesnât overheat.
I might test it anyway though.
Thatâs not a lot of CD but 28000 lumens in a spot does sound kinda cool
Use your imagination It isnât even built yet! xD
That is not taking into account the effect of the cross on throw from a reflector. The cross between the dies always takes up some area in the reflector, reducing the effective luminance. Though the XHP70.2 is better in that respect than the first generation. Texas_ace measured the sliced XHP70.2 at 6A (12V) in the BLF GT at around 65 CD/mm^2. I present you with Giggles, the most hardcore BLF thrower in the World. - #101 by Texas_Ace
I agree the CFT90 is in another league of brightness and output.
The cross doesnât affect anything, all the light from the dies goes to every point on the reflector.
There is no âtaking up part of the reflectorâ.
The result is simply that the lux in the center of the hotspot is not as high as the lux slightly to the side diagonally, where one of the square dies would be projected.
This is only for short distances though, far enough away the four beams from each individual die will have diverged enough that all the points in the hotspot have the same intensity.
65cd/mm^2 at 6A definitely suggests over 100cd/mm^2 at close to 20A.
When I look into the beam of a C8 with sliced XHP50 from 7m away there is always some area of the reflector filled with the dark cross, in the beam center and anywhere in the beam. What you say about going slightly to the diagonal makes sense, but have you observed this? In my experience with the four die LEDs it is always like I describe above.
Oh I see, so 12A 6v.
I havenât tested my XHP70.2 in a reflector yet, but from the modded GT beamshots there is pretty much no cross visible.
Anyway, Iâm just concerned about lux, not how visible the cross is.
Since the light will still hit the entire reflector the lux will be the same if you measure it where the die projection is.
As you can probably imagine, if you just take a single die LED and move it a bit to the side you will still get the same lux because the LED has the same surface brightness and the reflector has the same area.
Itâs just that the spot with the highest lux will be slightly over to the side off centre.
