how to DIY undercarridge LED light?

[chilskater]

can we 'reused' the LED(14LEDs) lampu picit as spot light?example..we take 2 lampu picit and stick together in fibreglass mould..

sure can... as long as the LEDs arent burned... hehe...:_:

can... u wanto use as spotlight... get those 21 LEDs torchlight... better... 14 LEDs dun seem bright enough for driving purposes...

but make sure u get the right input voltage to the torch light...

since u already got 12v LED, u can directly wire everything up in series or parallel connection....

remember add a fius at the positive terminal, jz incase of short circuit...

i planning to do so as well... but using 3.2v LED (normal rm1 LED sold in electronics shop)... need to add resistors and so on... hehehe...

btw, mind sharing how u gonna waterproof ur LEDs??...

Connect your fuis at ur battary rather than inside the car. if connect ur fius inside the car, short circuit will burn the wire.

khguan, hows the progress of ur LED?
Plz let us know the spec.

 

[khguan]

eh.. it will be abandone for some time... heheh.. no time to do it yet...

all just normal LEDs... using a 1Kohm resistor to reduce the voltage..

khguan become damn expert already la.. from fluorescent light to LED undercarriage already

 

[khguan]

eh... no expert la... mine very simple circuit only... will abandon this project for sometime... got free time only do...

 

[SkYwAlKeR]

haha... why abandon la??... let us see the result ma... hahaha.... actually i also lazy do lar... i got the LEDs adi... all components got oledi... but, do i really need it??... will it affect my battery load??.... scared use too much power, battery kong vr fast....

 

[khguan]

wun la... LEDs consume very very very little current.... lesser than ur alarm system...

dude

so by using a resistor(s?) you can change 12volt to 6 volt?

 

[SkYwAlKeR]

hmm.... if so, might try la.... install adi become lala chai also nvm.... hahaha...

*my friend say cars with undercarridge lights are lala chai car*

this i also not sure ler sifoo... coz as far as i know, resistor only reduce current... if to reduce voltage, u need a voltage regulator.....

 

[wyx]

to halve the voltage, try connect this way with R1=R2.

12Vdc --R1-------o-----6Vout

R2

Gnd

PS: connect R2 to Gnd at the mark o. I can't align the lines to its exact conenction :P

errr.. i guess using 680ohm should be fine... connect in series... but this is only applicable for LEDs as the load is very small... for stuff with higher current load, iti s not suitable to use resistor...
