LED Replacement Fluorescent Tube

Step 8 Variation: DC Socket instead of Bi-Pin

You can easily use a DC socket instead of a bi-pin connector. The pictures below explain it better than words can. Simply connect the positive and the negative connections in the circuit to your barrel plug.

Hi there.

How did you "difuse" the led's?

Thanks

To increase the viewing angle? Use sand paper.

CAN U TELL ME WHY WE USE TRANSISTORS IN LED CIRCUIT, AND CAN U SEND ME THIS TUTORIAL CIRCUIT DIAGRAM PLZZZZZ

I HV MANY QUESTION TELL ME IN PERSONAL MSG....

[chetan_m.p]

where can i find this circuit diagram???

If one so clueless, just forget it.

Very clever project! One thing that is not clear to me is the power source--can this be inserted into a fluorescent fixture as a direct replacement, or must the fixture be modified (as in remove ballast & rewired) in order to use the led version?

[computerwiz_222]

Well, there are two installations that can be done. One is to install a switching mode power supply into the fixture in place of the ballast. The other is to completely remove the ballast and wire up an alternative 12 volt source such as the batteries in a solar or wind energy based home. The second method is preferred for many reasons.

Now plug it into the lamp socket and watch the thing go up in flames because you forgot to remove the high voltage ballast! Very scary project.

Yes a good question I too have the same question.
