some new leds came in the mail today.....

[jason 77]

I just got the following LEDs to play around with....

1320lm bridgelux

400lm bridgelux neutral white

400lm bridgelux warm white

Rebel LEDs

Two 180lm white, Four 145lm white, two royal blue, and eight 50lm amber..

The bridgelux LEDs are fricken bright! but hard to solder leads onto...

whatcha gonna do with those ambers?

If you think its hard to solder the leads onto the bridgelux, then i sure hope your not hand soldering the rebels!!

Awesome stuff though!

 

[Airsick]

Nice! What are you using to drive the Bridgelux?

 

[bshanahan14rulz]

things that big can be hard to solder to if you have a crappy radiohut iron that doesn't put out enough heat fast enough. I imagine that's what he's talking about. Not that soldering rebels is an easy task or anything.... Just easier with a hotter iron or a hotplate.

I plan on using the amber rebels in the front turn signals on my car..

I have already had some experience hand soldering the rebels, the issue with the bridgelux leds seems to be there heatsinks sucking the heat away from the solder pads. So I am supposed to use more heat, I was keeping my station turned down so as not to damage the led? Should I turn up the heat then?

I am using the constant current circuit Dan outlined on instructables.com

Had the same problem with the pads on a SSR-90... 10 failured attempts with a 30 watt iron.... got it first try with the 230/150watt gun ;-)

Are you reflowing the pads first? It doesn't look like it form the pics.

So I guess I should turn the heat up on my soldering station?

I Tried to reflow them but no luck, I will try and turn the heat up on my soldering station I guess....

Thanks for that! I hadn't seen that.

more heat
+
put a bit of solder onto the pads without the wires
+
add wires and solder
