I have a 12v,2A adapter I wanted to use this for a metallic PCB leds.
My need is to glow
1)3 pieces of 3watt LED .ie:9W totally (As shown in picture) .
other one is
2)18 pieces of 1/3W LED.ie:6W totally.
Now these two connections are connected in parallel.
During my first test with 12V,2.5A adapter worked for15mins but adapter started heating up and finally its transformer burnt .
also when checked with my another 12v,2A adopter for once my LEDS are fine .
so I continued testing,
later I bought 12v,1A adopter now its working for about 1hour,same as before adopter is heating very much but my adapter is not burnt.
Now can anyone please say me what I need to do for proper and safe working of SMD LED's and Adapter.
