hello AAC!
I am zero in electricy things and I need u'r help here,
and sorry if my English isn't good enough. lol
i'm in spare time doing an experiment, i want to make a portable working lamp which can be clipped to a window frame or desk as a table lamp to,
this include:
-trichip smd5050 12v led 30module (90leds) @0.24volt, 21.6watt in total
-a box in dimension of 20x20x4cm
-the total cost is under $30 exclude the leds, box, and DC converter
What I will do is connect a 2Amp 12v DC adapter with 2.5m wire long to a wall socket to light up my led's , but I realize that my working lamp won't work if there's no electricity or wall socket.
so, i modify the idea which the lamp will also work with batteries but i don't know how it will works with wall socket to.
the concept is similar to a notebook while charging,
we plug the notebook's adapter and we work with the notebook,
and 2hrs later we unplug the adapter and we still can work for the next 2hrs without turning off the notebook.
Can anybody sketch me the diagram for my working lamp?
and what items should i buy and fit in 4cm space under 30$?
really appreciate all u'r replies.. thx
