Converting machine light to LED

lundi 22 septembre 2014

Hi All



I bought a little centec mill recently and have been working on it, see other post. It came with what was originally a very good quality 32volt machine light which had been rewired to 240volt, not I think a great idea. This is the light as I got it with the 32volt Rowco transformer. I wanted to modify it to 12volt and reinstate it.

I paid a visit to the green shed and came away with this. A 12volt downlight kit with a transformer and a socket, it also included a 35watt halogen bulb that I wont use. I also bought a 7w LED bulb that I thought would fit the socket. It actually didn't fit the outer shell but did fit the socket itself.

My original idea was to modify the whole downlight socket to fit in the original lampshade. This proved to be difficult and unnecessary and what i ended up doing was modifying the inside of the original light to mount the small white socket that takes the LED bulb.



Here you can see the original bayonet fix core of the light with the socket for the LED mounted to it. The original core has been cut shorter at both ends and the brass ring that held the bulb has been prized off. The screws that hold the LED socket fitted through the original holes for the bulb contact pins. I drilled the original wiring posts to use as spacers under the new screws. One has been done in this picture.

The original bulb carrier, with the new socket attached then screwed back into the original top fitting.

This is the top fitting with the bulb installed and the shade back on.

This is the whole thing reassembled, the transformer is sitting on the back of the vise. It is under a skylight here but you can get some idea of the pool of light that it throws. I think that it will be really good on the machine. The LED is literally cool, I can't discern any temperature rise at all. When I reinstate it I will tuck the transformer up under the base of the mill.

This proved to be one of those rare jobs that was easier and quicker to do than I thought!
