DIY LED thread (Im at it again)

thanks guys for lookin out i had it confused. yea smog def do a detailed installation it would be greatly appreciated by all of us diyers

 

[reefoman]

the picture from smogs build confused the crap out of me how he wired up the dimmers i have no idea with that wiring. isnt there a port on the driver to put the dimmer right to?

To dimming D series drivers you can use cheap adjustible ac/dc wall adapter it has scale 1,5v-3v-4,5v.....
D series working at 100% when you gonna provide 10V to the two dimming controlling wires thats mean if you gonna adjust wall adapter to 4,5v your leds gonna work aprox at 45%, but be carefull there in mean well driver is positive and negative wire.

i think i got it right this time. - is on top and + is on the bottom of the led

 

[Tonyscoots84]

and also i can use #10 copper awg right?

 

[chinatown]

and also i can use #10 copper awg right?

too thick. use stranded 18 gauge to 22 gauge.

 

[Tonyscoots84]

damn i have plenty of #10 ... lol

I used a solid core, not standed. I think its a lot neater with a solid core.
But 10awg is too thick, 18-22 is good like chinatown said.

Also, on the meanwell driver, the V+ goes to the + on the LED first. And V- goes to the negative on the LED. From there, you alternate + to - to +...

solid or stranded is indyvidual choice, but if you are looking on this from electric side stranded has better bandwidth than solid and is more flexi if you gonna change your mine after soldering you can move the wire around w/o worrying about crack...

for interested...

isnt that what i did ming?.. thanks guys

Stranded wire is more flexible but not as efficient as solid wire. Solid wire will carry more current before failure then stranded. What bandwidth, you're dealing with voltage not data.

Any reason why you did not choose Cree-MC-E ? They have 3 x the light ouput as Cree XR-E @ 700mA

 

[Tonyscoots84]

i think i didnt go with them cause they are 20 bucks a pop

Well you are right maybe bandwidth is bad word but you have to forgive me my bad english sometimes i can't find good word to situation...

Here is what i mean...
At high frequencies, current travels near the surface of the wire because of the skin effect, resulting in increased power loss in the wire. Stranded wire might seem to reduce this effect, since the total surface area of the strands is greater than the surface area of the equivalent solid wire, but in fact a simple stranded wire will not improve skin effect since all the strands are short-circuited together and still behave as a single conductor. A stranded wire will have higher resistance than a solid wire of the same diameter because the cross-section of the stranded wire is not all copper, there are unavoidable gaps between the strands (this is the circle packing problem for circles within a circle). A stranded wire with the same cross-section of conductor as a solid wire is said to have the same equivalent gauge and is always a larger diameter.
However, for many high-frequency applications, proximity effect is more severe than skin effect, and in some limited cases, simple stranded wire can reduce proximity effect. For better performance at high frequencies, litz wire, which has the individual strands insulated and twisted in special patterns, may be used.

boomer money is just money but not when your saving up for a very expensive wedding :theyareon

I never did commit suicide, let me know what it is like in a few years
