Ah kijk bedrijfsspanning: 2.6 Volt dus in serie geschakeld: 2.6*18led's=47 volt. terwijl een ledstrip waarvoor de controller bedoeld is 12 volt is. Dat gaat inderdaad niet.

Ja en dat is het probleem. De controller kan maar max 24V aan :)

DC Forward Voltage (VF): 3.3 ~ 4.2Vdc

dat gebruiken de leds die ik gebruik.

Ja inderdaad daar hebben we hem. gemiddelde bedrijfsspanning is 3.75* bv 18 leds=67.5 volt. Dan komen we bij de volgende vraag, welke controller werkt onder die spanning. Je zit al gauw aan de 18 wit en bv 6 blauw die tegelijk aan zijn, niet in volledige sterkte maar goed. Dus dat zijn 24 leds*3.75 volt +10%= 99 volt....

Zoeken dus naar een controller die een maximale voltage heeft van 99 volt ;)

Hey Jeff, ik heb een idee. Een 12 volts driver gebruiken de ledjes groepen is groepen van max 12 volt 12/4.2= is 3 led's per groep. Oke met een grote lamp is dit niet haalbaar, maar wel mooi voor een test!!!! Dus een driver gebruiken voor 3 led's met 3 ledjes en dan de controller er tussen. Dit zou voor een test moeten werken. (alles afstellen aan het juiste voltage)

Ik ga eerst even testen of 1w leds werken erop. Ik weer namelijk al dat 3 stuks wel werkt :) maar daar heb ik niks aan haha hij moet alles gewoon doen :)

Wat je wel kan doen is de ledjes in serie schakelen per 3, dan heb je een totale spanning van 12 volt. dan kun je telkens groepjes van drie op een kanaal aansluiten.

Dan kun je dus elk kanaal tot het maximale amperage belasten, dus zeg 2 amper per kanaal is 3 groepjes van 3 leds per kanaal met een voltage van 12 volt. Nadeel is alleen dat er nieuwe bedrading moet komen......

De 1watt leds werken wel, als je maar onder de 12 volt blijft gok ik zo, en dat is denk ik ook met de 3 watt leds.
