I decided not to order / use the power supply typically sold with SMD 5050 kits. I heard a lot of explosion stories regarding those dodgy stuff.
I want to make my own (power supply to drive SMD 5050. Using: a DC adapter found at home hooked up to LM2596 converter.
From what I gather, LM2596 regulates the voltage AND can supply 1 to 2 amps of power safely (more requires heatsink?).
A single SMD 5050 chip uses 0.24 w of power.
SMD 5050's run on 12v.
- Is it safe to assume that I can connect any number of LED strip blocks (with each block having 3 LEDs each using 0.24w, therefore ~0.75w), as long as total amps do not exceed what LM2596 AND power adapter attached to it can supply (being max 2 amps)?
watt = amps x volts means each LED uses 0.02 amp.
So if I have 30 blocks == 90 LEDs.
90 * 0.02 = 0.6 amps.
Would it work fine?
And if I just connect a single block needing 0.02 amp, would it still work fine?
What would happen if I connect more LEDs and exceed the amps LM2596 can provide?
I don't want my leds burning in day 2 and learn about this subject.
I'd very much appreciate it if all questions were answered.
