LED Wiring question

Forgive me for kind of double-posting this, but I didn't get much response before. I put up a question regarding LED wiring here: https://www.instructables.com/answers/New-to-LED-wiring-could-someone-help-me-make-sure/Could I get someone to help me out? Again, if double posting like this is wrong, feel free to remove this thread. I don't want to cause problems, I just want someone who's smarter than me to help out :)Thanks!

LED Wiring Question

Prologue:  Please be gentle...once I get past V=IR and the "right-hand" rule, I'm lost to electronics.  But I can solder and follow a schematic. I have several (7) LED sets (each set = 10 LEDs with power pack containing 2 AA batteries, switch, and resistor).  Each set of LEDs are all the same color (if that makes a difference). Image attached. Question:  Is there a way to connect all LED sets to operate with a single switch and maintain each set with it's own power supply? On a lighter note, I'm building a project for some pre-schoolers and want to hide all wiring and switches from those "inquiring minds" and "wandering" hands. Thx in advance. Paul D

LED wiring standards?

Making a wooden rangehood for my wife for our annivesary, and I want to use LEDs  for the light source. I wan to use 3 banks of 30 lights in each 4X8" oval space, and from what I have read it would seem to better to wire each set in parallel. My question is, do I need to put a resistor on each LED to adjust the voltage to the proper amount, or (since it is wired parallel) will one work for all?

Wiring your LED

So I just built a new garage and I want to make my own LED lighting for my work bench. I was looking at 1 watt luxeon leds and I was wondering if I need a resistor with those leds? I was looking on ebay and it said that the driver is already installed? I will run these with a PC power supply rated @ 800 watts will this work? Can anyone guide me thru this? Ive been looking on here and reading as much as I can... Thank you.

Dollhouse wiring

Hi All. I'm a believer in the idea that anyone can do anything with a little info. But I'm in need of a little help.  I'm building a dollhouse for my niece and would like to add a little higher-tech slant (she won't be playing with this for a few years yet...)  I would like to add LED lights (which I will make but just have to wire for at the moment), a flicker fireplace and a door bell all on wall mounted pushbutton switches.  Feel free to suggest anything else that might be cool for a kid... The whole system will run on a 12V adapter but since I need to wire this NOW so I can continue to build, I need a drawing or schematic of how to do it. I've attached a pic of the house and have been pulling apart some of the small flicker Tealights to kitbash into the fireplace.  I have a number of white LEDs with which to make the lights but they don't have to go in right now.  I know I'll need some resistors - where do I place them?  Hide them in the walls?  On each switch? Anyways - any help is so appreciated.  She'd never get anything like this unless I made it for her - I just want it to be so cool that her brothers are impressed! Tbird

Replacing LEDs on a LED fan? Answered

If the LEDs are the same voltage, can i just cut the wires on the LED fan, and just simply re-solder the new LEDs onto the wires? I have been looking at several Instructables about replacing the LEDs on a fan, and they all have complicated re-wiring ideas..Can't you just simply replace the LEDs with the news ones?

Wiring Question

Ok, I recently purchased a Go-Ped for practically nothing, and I really, really, really want to fix it up. I want to mount a couple of LED powered bicycle headlights on the front, and a tail light on the back. However, I want to be able to turn them all on and off via a single switch, mounted to the handlebars.I know very little about wiring, but I do know that most bicycle lights require physical pressure to power them on or off. Maybe there's something that can go between the batteries and bulbs?Any input you can provide would be fantastic!-Ryan

How to wire up this LED?

Hello there, I've bought this cluster of red LED's from Maplins and I'm unsure how I should go about making a circuit that lights them up using a 9 volt battery. (I also have a simple switch). The forward voltage of the LED is 2.5v and the forward current is 30mA. According to my calculations I would need to put a 1/2W or greater 220 ohm resistor in the circuit. Is this correct?Also how do I go about wiring the cluster up as they are in fact 6 individual led's. Do I need a resistor for each? My knowledge of electric circuits is limited. Many thanks, Julian

How to wire leds together?

How might I wire 25 LEDs ( total 60v) together? Right now I'm planing to wire them in one series connected to seven 9v batteries (63v) wired in a series (LOL?). I'm using the batteries because I don't want to have to deal with AC and I would like to be able to use the LEDs if the power goes out. I will add a 150 ohm .6 watt resistor and a switch in the circuit. Am I doing this right, or is there a better and/ or safer way to do this?

LED driving and wiring question? Answered

I have read and read and read, and am still confused no where seems to be able to give me a straight answer, so i've come to the instructables forum for help.  I am planing on wiring 16 leds in series driven by a driver. The constant current driver's specs are' in   -  85-277V, 50/60Hz, 0.5A MAx  out -  650mA, 30-60V, 40W The 3W leds run at 750mA, 3.2-4.0V so each led circut should require 52.1v-65.5v,  and 48W. I was hoping to under drive them to increase their lifespan, as i had a different project fail when one led blew and killed the entire line.   My questions are; 1) can i run 3 of these circuits off of one standard north american  plug 125V?  2) will this work? and did i miss anything?  3) can anyone recommend any simple improvements? I've done as much research as i can, but i never have been good at electronics and circuits. and half of the things i find are contradictory. That's why i went into chemistry.  Thank you for reading this, and thank you for responding and helping me!

Help wiring an LED array

I'd like to buy some LEDs off ebay and build some LED arrays but I'm confused as to how to wire it. For example, lets say I have 100 watts of LEDs (aka 1 watt x 100 LEDs or 10 watts x 10 LEDs) as an extreme example and each LED has a max voltage of 12 volts. Then lets say I have a power supply that provides 100 watts at 12 volts. How would I wire it? I'm worried that if I hook it up, lots of LEDs will just burn out. Just help me understand what I need to watch out for here. I'm obviously a super novice. Have pity.

washing LED's?

I want to weave a rag rug, and include LED's in the rug. Ideally, I would like to weave the wiring and LED's into the rug so that they are concealed in the rug- and not removable. But most people like rag rugs because they are machine washable. If I were to soak a LED wired rug in soapy water, rinse by hand and only use the machine to spin the excess water out, then line dry the rug, would the LED's still work, or does water destroy them and the connections? Thank you for sharing your expertise!

LED Voltage? Answered

So recently I had an idea to make a steam gun by heating steam with a NiChrome wire driven by a 9v battery, anyway, to keep it safe and so i knew when it was on, i decided to add an LED to the circuit. I went to http://www.hebeiltd.com.cn/?p=zz.led.resistor.calculator to see which resistor i needed. From what i understand, the resistor limits the CURRENT across the circuit. So, what i want to know is whether the Led will work with the first attached circuit and not bun out from the voltage, and whether the nichrome wire and led will work in circuit 2. EDIITTT: Well, after a few answers, i'm realising i cant run this off of a 9volt, so, what small powersupply could i use?

LED Mouse Mod?

Ive been trying to do a mouse mod where an LED lights up everytime I click. Can someone please post an instructable? or else i will when i get it figured out. what i figured was that i would have an led with a resister hooked up to the 5v part of the circuit board on one of the legs.. then i would have the other leg soldered to a wire and to make the LED light up, the circuit would have to be completed by clicking the mouse down. But the problem is i cant do that without messin up the clicking function. when i tested it the mouse click would be stuck. So i will post an instructable when i figure this out if noone else does. please leave a comment if you figure something out.

Led Help

I have a whelen white vertex led light head. Normally there is a 12 volt dc controller already attached to the light it self that controls the flash pattern which you can change. However some one cut the light head off the controller part and the controller cant be found so now i have just a light head with 3 wires red black and green red being power green and black being ground. there are a total of 6 leds 3 off the green wire and 3 off the black and a common power wire. my problem is i cannot figure out the proper voltage and ampures needed to power the lights. i have tried to ohm the leds (and yes i tried every which way with the leads) but i suppose my fluke 115 does not have the range needed for these lights. i connected a known working light and controller to 12 volts and mesured the power going to that light which read which read about 3.7 volts at .36 amps and each set of 3 leds being .18 amps and with out any leds connected i got 5.2 volts i just want to make sure this is correct before i put 5 volts and a resistor to them and they blow. ill post pics and a crappy diagram of what i think is in the light head

LED advice

So, i'm a pretty avid fan of our local roller derby team (HKRG BABY!), and i belong to a group of super fans who focus on doing a lot of weird crafting and costuming and other such insantiy for the bouts. so, i'm wanting to make some pretty fancy signs for next year's derby season that will  light up. i've got some plans to use some EL wire/tape and the accompanying equipment but i've also got some other sign plans that would probably be cheaper/easier to make using LEDs instead. so, basic premise is to have a sign that would be able to light up some cut out letters separately and sequentially. i know how to make the sign itself so that's not the issue, what i need is a method to cheaply and easily make the letters light up in sequence. so it's a 3 letter sequence (let's use D O A as an example) that progresses at the normal speed that you would imagine a large group of people chanting a 3 letter call sign to go. so the D would lights up for a second or two, one-two second pause, O lights up for a second or two, one or two second pause, then the A for a second or two, lather rinse repeat. i'm imagining that each group of LEDs for each letter would be wired in series, then each group would be wired to whatever circuit would be needed to make the lights cycle. i'm not sure exactly how many leds will be needed per letter, but maybe between 10-20 of them per segment? i'm going to have several of these types of signs (all 3 syllable chants) so i'd like it to be something that's easy to repeat and not terribly expensive (i'm a derby nut, but there is a line where cost kind of gets stupid)

How do I wire these LEDs?

I'm need to wire 4 blue LEDs (3.4v) and 2 ultra bright red LEDs (1.9v), I would like to limit the current to 10ma and wire all the LEDs to a single wallwart. The wallwart I was planning on using is 12v DC 100ma. I'm pretty new to LEDs so I'm not quite sure how to do this, I was thinking about wiring the 2 reds and 1 blue in series and wiring the other 3 blues together in series and then wiring the 2 sets together in parallel. But I'm not sure if that will work because I read somewhere that if you're wiring in parallel all the LEDs must have the same voltage. So if anyone could explain how I could wire this up (and maybe even draw up a simple diagram) that would be great.
