can teach pls or link a guide?

easy one bro ,
1.all u need some led(how much u want to change the led) buy from forumer very cheap one(got blue,green,uv purple and white) at bulk order

2.remove the led that already faulty by open the white glue which is together with led(easy,just try peel the glue,easy remove).

3.attach the new led to the hole of led at fan casing.(remember the led leg(positive + and negative -)
i
4.cut the faulty led leg,dont cut the wire,the wire will become short,if this happen,try solder/"lilit" another wire to connect it.(i use to cut the faulty led leg,so the wire become a bit longer and can solder or lilit it to the new led )

5.connect the wire to the new led with the same connection with the old led(faulty one),careful check the same leg led to connect it.

6.this the picture :



7. carefully check it before u solder it or just like me,"lilit" it coz maybe other day want to change to a new Led

8. glue it with the hot glue (like the original one,can find the glue and the glue gun at RM2 store or buy from forumer) wait the glue to dry.

9.After above procedure done,connect to power,3 pin or molex power.

10.Done

thanks a million bro.. will try it a.s.a.p.!!!! U are a life saver!

Added on June 30, 2008, 11:28 pma question bro, the wire got two colour, red and white.. red is + or -?

u r welcome

just look at the faulty led leg which color wire it use,use the same leg for the same color.

u need look at this picture :



i mean like this picture,u can see that i curcle that positive leg,if the red wire originally attach to positive leg before u remove the wire from the faulty led,just use it for the positive led leg of new led with same red wire for positive.

u can see it clearly at the led,which is positive and negative

got it bro.. still order my led bulb.. hehehe.. will try it after got my led..

good luc k,order from hensem? hehe

they use white as common - and coloured one is +... hope that helps.. btw what kind of LED u guys want to make in this thread?... i can give a few ideas and how to do it if you like...

i want using blue or uv purple for my casing,come2 teach here,thank u sifu,hehe

u want to make a tube of LED or like christmas tree lights ?

i just want to use molex for power and resistor,led,i just want to know how to do it,hehe

is there a plug n play decoration light is available.. i am not so sure with this thing..

can a led attach to power supply but have a switch on behind or something like dat, so i can on or off it as i like..

Does resistor is needed necessarily? coz i remove my icute led tube and put in my another casing. seems like the LEDs doesnt need resistors( direct power from molex) or am i wrong?

i also dunno chyu89,but pmmonkey use resistor..

But whats the usage of resistor? think it might reduce the led brightness? or reduce current flow like a transformer.

the used of resistor is to avoid ur led blow due to over voltage..

a resistor limits the amount of current going in... An LED usually only needs 0.22mA.. overcurrent makes it run brighter and burns out faster...

oh, got the point, but anyway my LEDs cheap only ma.. bought from electronic shop, not going for the top class 1.

new student here i got switch spoil ? can some one help the switch is the on off button

buy a new switch at electronic shop,hehe

want to ask anyone here,can i add a switch on./off at my ccfl? (using cooler master,dont have swith..hehe
