    Re: 120 volt ( AC LED Clip-on Lamp ) 48 volt LED module Hack

    UpDate

    I took one of these modules and did a mod to it

    has six LEDs on this module so

    I cut the trace so now it has two sets of three LEDs in each one so now instead of 51 volts it 26 volts

    I found a place where I can get a 29 volt switching power supply to power it

    I been thinking about modifying the hole light bar so it will run on 29 volts and current regulartor which easier

    I have not found any current regulator that work with voltages high than 48 volts

    1 Dell Mother Board
    15 Computer Power Supply
    1 HP Printer Supply & Control Board * lighting finished it *


    These two repairs where found with a ESR meter...> Temp at 50*F then at 90*F the ESR reading more than 10%

    1 Over Head Crane Current Sensing Board ( VFD Failure Five Years Later )
    2 Hem Saw Computer Stack Board

    All of these had CAPs POOF
    All of the mosfet that are taken out by bad caps

      Update yes I know that this is a very old post but I had put this project on the back burner and now I found a use for it more information to come soon


      I am going to use this auxiliary power supply board on this switching power supply that I am taking about in this post

        Update

        On this auxiliary power supply board I not going to use it on this switching power supply but I going to do this modification again on another one but I going to only make the output voltage 50 volts not 75 volts and not going to use a very small heat sink and try to mount it in the same case but I need to buy some more of the Schottky rectifier diode for this modification

        The output of amperage is only about 1.5 so I do not need a very big heat sink for this purpose and this is only thing that is going to be used on this auxiliary power supply board
