My diy led light sketch But witch controller to use???


Hi i am looking for a controller for my led project to dim, moonlight, cloud........ so i come up with a few of them. I was looking at arduino uno diy but i do not have enough knowledge in electronic to build it and no programing knowledge. I Know there are a few "program" here i do understand the basic of how it work (well i think i do ) but its not for me so i come up with those

http://coralux.net/?wpsc-product=storm-led-controller-2

http://coralux.net/?wpsc-product=storm-x-led-controller

http://shop.stevesleds.com/Typhon-Ty...ler-Typhon.htm

The coralux has more option (storm-x more channel) that i like and its base on arduino program (you can download the firmware of it on the web page so if someone have the time to look at it and let me know if it seem a good well done program it would be more then appreciated). The thyphoon seem more basic so probably more "stable", easier to setup but lest channel. So if some electronic master could have a quick look and give me your opinion one those it will be really appreciated. And if you have an other controller to recommend let me know.

Thanks

You need LED drivers - constant current drivers - to run LEDs. To do the various lighting cycles you want, the LED drivers have to be dimmable, and the type that are controlled by PWM, not a variable DC voltage.

Go with the Storm X controller. It's got the best dimming performance available right now with 16 channels and 12 bit dimming. I build my own version of the "typhon" controller and have used them for the last few years, but the Storm X is by far better.

Thanks for the help

Here is an other question. What size wire would you use to joint the Led? I want the smallest but safest possible.

20 - 22 gauge solid core wire works great for connections between Leds, but you'll need to use stranded wire between the drivers and the leds.

Correct me if I'm wrong but don't LDD-700H drivers need 4 move volts on the input than output. If you wanted to drive 12 3w leds you would need like a 50v+ power supply.

The maximum number of leds that can be driven is totally dependent on the Vf of the leds and the current level they're being driven at. The Vf of an led will vary depending on the current, so more leds can be driven in a series string at low current than at high current. Another item worth noting- Most "voltage adjustable" power supplies can be adjusted + or - a certain percentage. I've got a 48V power supply that has an adjustment range from 40 - 56V.

The vf of a 3w led is going to be at least 2.9v and well over 3 for the cheaper ones. I don't see how he is going to adjust a 12v power supply high enough without some kind of booster.
