daft question on LED indicators and high VDC

Get a grip !!!

Re. putting more diodes in series, maybe this is the next trent for control cabinets

Set me thinking though, I have a reel of white smd Led's bought for a job that never happened.

Maybe this thread would be useful ?

I have just made and installed a control panel for a glass blower friend. The labels for the modules are fibreglass circuit board. If you put LEDs behind them the lettering shines though beautifully. Next phase of project ??? I might even go full steampunk. maroon and green with gold striping and ornate Ibis carvings in the blank areas of the panels and , of course I would have to change the stainless metric button head screws to whitworth bronze slothead.


The picture btw is a screenshot of an IP camera set up to view the panel from anywhere.

Nice work on the furnace control, just for those still not disillusioned with LEDs have a look at http://www.onsemi.com/pub_link/Colla...I45020JZ-D.PDF http://www.onsemi.com/pub_link/Colla...SI45030A-D.PDF and there are versions of this with different current and voltages
I'm still trying to work out how to use a illuminated led as a switch if any one has done this let me know

What ? do you mean with an LDR or something ?

[cropwell]

I think you might mean as a touch switch - I presume you could use a metal cased led on an insulating panel as the sensor on a touch switch circuit

Pick one !

no, not a metal can version a basic 5mm LED .....my thoughts the LED stays on, capacitance on one of the LED pins is the switch so just touch the resin or get close and the switch action operates the led to turn off or any output can be turned off
