So I was at the auction 2 weeks ago, and this came home with me. $20 of the $150 I spent that day. Biggest item was a built in BBQ I bought with my friend, to put in his entertainment area. This was my spend.....
Here we have a Bioptron 2 light therapy unit, made in Switzerland ( cue the Hi to all my Swiss viewers) around 2002, which is basically a yellow light source, using a 12V 90W halogen lamp ( really odd power that, I would have expected a 100W lamp instead) in a optical arrangement that uses what appears to be a dichroic or polarising mirror ( haven't looked with a polariser, all I know is it dissipates half the beam power as heat turning it 90 degrees), and then a yellow filter glass.
Price new ( seems it is still a current production unit, or at least recently discontinued to still have plenty in a supply chain) is eFfing crazy, here in ZA I saw them advertised new and used from R74000 ( around $5000) to around 5000 GBP. Somewhat steep for what it is, but it does have a nice stand ( not shown here, it is in pieces in the garage) with quality metalwork and good GRP castings.
It of course does not work, with a label saying the lamp is faulty. Surprise surprise the lamp is still good, it is the main PCB that is faulty. Having a quick look with the Chocolate factory, and especially the translate ( or the text mangler to be more accurate) function, I got some Hungarian websites where they were more familiar with these units. Seems stock faults are either the PIC microcontroller on the display panel losing it's marbles, which is fatal, you need a new board from Switzerland, made by Quattro Engineering, and they apparently think the board is made from gold pressed Latinum. The other common fault is the little grey mains transformer cooking itself, or the 5V regulator attached to it made from some discrete components.
I seem to have the transformer cook issue, so I will go unsolder the little 15VAC transformer and look for another one in the box of dead industrial controllers, which uses a lot of them. might need some slight bodging to get it to fit. Other alternative is to simply remove it all, and make a diode rectifier for the cooling fan and use an external 100VA lighting transformer instead, which will also work. I have some of those transformers, KolbeP did not get all of them........
