SMD LED, need Help

Zarnikon · Sep 14, 2010

Ok, here's the thing i just bought a SMD LED for learning purpose.
It's the following LED: L-HP3PWN

High-power LED driver: K8071 or VM143/3W
super high-flux output and high luminance
very long operating life (up to 50 000h)
low thermal resistance
SMT solderability
no UV output
superior ESD protection
colour: pure white
luminous flux: 170lm
dominant wavelength: - nm
colour temp.: 6000K
viewing angle: 110°
thermal resistance: 48°C/W
forward current / voltage: 1A / 3.5V
power dissipation: 4W

Now's the problem, I don't know where and what I have to solder.
I've got a matching resistor and some good 3.6V batteries.
So that's where I need the help. Where do I have to connect the negative and positive pole of the batteries?

Thx in advance!

Nobody that can help me?
I just need some directions where to solder the stuff.

Z,

Just connect the battery + to the + pad on the star, put resistor on the - battery lead to the star. Use just 1 battery, two will :poof:

the LED.

OK, that I knew, didn't know where to put the resistor though thx.
What I was wondering if I had to do something with all those silvercolored pads, there are 6 places to solder but you only use the ones connected to the LED. So I connected 3 batteries in parallel. It's a nice and bright LED but the angle is to wide, i'll take a picture of my chamber with the led and with my 2 flashlights

The two marked + and the one between them are the same, ditto for the ones marked -. The resistor has to go in series with the LED. So a wire from battery+ to resistor, resistor to LED+, then from LED- to battery-.
