Hello and thanks for reading this,
I am a technician in a sheet metal shop and I endup doing a lot of machine repairs. We have a machine that cuts 10 foot pieces of sheet metal, and there is a bar with standard incandescent bulbs to help you line up your cut. These Bulbs constantly burn out and blow fuses. The Bar they are mounted on moves with the cutting beam, and I think that the often jarring motion is taking its toll on the lights.
My solution is to install LED lighting which is more durable and brighter than the existing light strips. there are 15 lights spaced apx 8 inches apart in small recesses in the bar.
the current output voltage is 24 v ac.
I have done a little reading on google and found some very useful articles, but this being one of my first "electronics" ventures, i am hesitant, because i dont really know what im doing
Building a Power Supply - Electronics in Meccano
this is an article that i found very useful, and their package rectifier board (figure 5 at the bottom of the page) project converts 7-35 v ac into an output of 5Vdc
although i know it isnt much to assemble led circuits I may opt to go with some modules i found that seem to be useable and simple, unless i am otherwise convinced.
LBM Dimensions (mm)
these modules need an input of 10- 14.5 V DC, so the output of the afore mentioned is going to be insufficient.
I am not sure what determines the output voltage in their circuit. I know the rectifier will reduce voltage by something like 0.4 v according to the articles following pages. and the capacitor will be a smoothing agent, so it seems to me that the 7805 regulator is where its at?
Also the existing lights as may be assumed are connected in parallel which is how i plan to configure the replacements. i know that parallel resistors reduce the overall resistance of a circuit, but im thinking that it increases the amperage, so what do I need to account for to prevent that?
Am I missing anything else???
i am telling you what i THINK i understand, so whatever is misunderstood, please correct me...
thanks again for the read, and the advice.
Dave.
PS, let me know if you need custom project boxes out of sheetmetal?
