First off, thanks for having a forum like this where someone like me might be able to get pointed in the right direction.
I'm working on a little "moonlight" project for my aquarium that might lead me into doing some larger projects. It's been nearly 30 years since I took electronics in college. So, go easy on me. I've been doing online research into this project and some things are coming back to me. But, better safe than sorry. Thus, my noob questions.
Here's my goal: Make 3 pendant style fixtures each containing 4 blue leds. All powered by the same source.
Here's what I have: A pack of 20 LiteOn LTL17KCBH5D-002A. And a 12VDC - 1.5A power supply.
Now, like I said, it's been awhile. And looking at that data sheet, I'm thinking these are 1w leds. I was told by the acquaintance that gave them to me that they were 3w. But, I don't see it. They have a Vf of 3.2V and If of 30mA.
So, if I am right, and they are 1w, I could get a boost converter and run all 12 in series from that one PS. Correct? Now, I admit, I know little about boost/buck converters (might go without saying). So, maybe I need a larger PS from the start. I have another that's 30VDC~830mA
Any insight into this is greatly appreciated.
