Hi. As I try to learn electronics, through reading plus trial and error, I thought building a desklamp would be nice small project for learning. Lamps body is ready, I've brought a 5050 led strip and that's when the trouble started. Before all of this, I've tried to consume many info on electronics as I can for a beachhead.
What I used is 5050 led strip of 15 cm (9 leds with 150 ohm resistors)
Label and the owners site only says 12VDC and 14.4W/meter max.
I've tried using 4 1.2V batteries for making the lamp mobile but didnt even lighted up. Found an 12V 1A adapter, plugged it in, overheated quickly, plugged it out. Although I would liked to wait for it to create a fire hazard.
12 V Lights up whole 5 meters, so why using batteries for 15 cm is not enough?
12 V for 500 cm, also 12V for 15 cm, why is that?
I also need to find out how much amp each cell needs for assembling power supply. After finding it, should I multiply that amp with the number of leds? Because that doesn't gives me reasonable results, what am I going to do with amps?
I've searched for an answer but didn't managed to find one and started to experiment. Used batteries to light up individual parts of one led so looks like there are no 12V minimum to pass electricity on them to produce light. I've burned and dissected many leds and wasted so much on searching and still didnt found the answer. How the hell am I going to light up this simple led strip effectively, what am I doing wrong?
I'm feeling really stupid for not being able to create, even understand the right power supply for a basic led strip.
