Your order is incoming as we speak with the rest of north Americas LED’s.
The shipment from clemence is set to arrive on Monday according to DHL.
It should not take me more then a few days to sort them, re-pack and re-ship them out to everyone on my list.
So hopefully they will be on their way to you by next Thursday at the latest and should be delivered the following week unless you live close to Texas.
They should be delivered to those in the US before Christmas.
I have a question regarding the Nichia 144A LED´s.
I want to build a Light Bar for my workshop. I want to use 3 or 4 x144A 9050 sm573 LED´s in series with this driver (http://www.banggood.com/250W-12-50V-Adjustable-10A-Aluminum-Board-Power-Boost-LED-Driver-Module-p-1026633.html?rmmds=myorder). I want to drive the LED´s with max 3A (total W max all LED´s together 100-150W). My question is if the Aluminium Profile is enough to handle the heat from the 144A´s (LED on Djozz Nichia MCPCB fitted on the Alu Profile with thermal glue). And i hope that someone can tell me which TIR for the 144A is frosted an has the widest spread?
I am not good with paint software but i hope it is possible to see what i want to build.
Yes, that setup should work, you might need to add a fan blowing through the inside of the tube to keep things cool but that is not hard.
Far as the tir goes, there are a lot of options, just find something with a wide beam angle and that is sized to fit the XM-L. I have only really messed with the narrow beam angle TIR’s myself but I did get a 90 degree tir that gave a nice even flood and they have even wider ones as well.
You also will very possible have to make some kind of spacers / centering ring for the TIR to mount to the top of the tube, it is unlikely that it will be just the right height to “snap” the tir into place.
FYI, not all XML TIR suitable for 144A. I’ve tested some TIR meant for XML and they don’t fit. That’s because 144A emitter is slightly taller than XML. You better start searching for XHP50/70 TIR. And as a bonus you’ll get better beam profile since XHP50/70 has rather severe artifact problem. All good TIR designed for XHP50/70 overcome this problem with some kind of colour mixing put into the design.
For workshop application I really like the Jenny CY from Ledil, it’s an excellent fit for 144A based on the data sheet. Haven’t try it yet
144A designed for high bay application and so does Jenny CY. It will give you a rounded square even illumination on the floor. http://ledil.com/luopdf4.php?s=54&t=18511
Those aluminum profile won’t be enough to cool 3 x 144A @3A if you want to keep the Tj lower than 85C. Edit: I didn’t see your annotations.
For more surface area you can drill as many as possible holes on it. The maximum surface are gained with hole diameter = aluminum profile thickness.
Ah……that explains. I didn’t check the annotations at the picture. To me, judging from the picture’s scale, it’s about 50cm or something.
If it’s 200cm then it should be OK.
Thanks for correcting Jeroen.
Theonlydocc, here’s a scaled drawing I made for you. If you want to update the dimensions, just let me know.
