RE: LED lighting

[Mark Hallows <markhallows@xxxxxxx>]

Thanks to everyone who replied.. I will start my steep little learning
curve
now and maybe film my landing strip garden path in action.. :-)

I am now definately in the "LED's are cool" brigade.. Lets see if
I still am
in a few weeks time.. :-))

Hi Mark

No books I  know of but plenty of advice. Check out my step lighting at
http://www.mollyology.com/MyHouseGardenStepLEDLighting.htm
and if you have
any questions fire away. I used blue LED's from Rapid Electronics at about
a quid each and 470 ohm resistors to stop them melting. I also made a plug
in arrangement for each lead in the theory that I could replace them if
needed but so far after a couple of years now all is still well. They are
weather proofed with small heatshrink on the individual leads and then
another larger heatshrink around the LED base and the leads together. I
used the 3:1 shrink ratio as I get a better seal with this. In hindsight I
would have soldered the resistor to the LED leg rather than in a box where
they were all together but that's life. They have even survived some
rather enthusiastic attention from my petrol driven strimmer !!! It is all
controlled from HomeVision but an X10 module on the power supply will do
just as well.

Have fun

Ian

Is there a book I can buy or a website I can go to to find out what you
are
all talking about ?? :-)
I thought the Kitchen looked great and would like to do something similar,
plus the whole delay cascade thing you mentioned means I now want to
waterproof them somehow and lay them alongside a path I am having laid...
Attach this to an IR sensor and Very cool effect I think I may have... :-)

Would this be possible ? for a total beginner with little to no
electronics
or welding experience but stacks of common sense and enthusiasm ????


Good job Andy,  looks great.

I'm doing something similar withy a couple of glass display cabinets at
the
moment.
I bought a Luxeon Star 1W Lumiled with collimating optic from Farnell
(Ignore the errors in the catalogue, the lens gives a 10deg. beam angle)
These fantastic LEDs give plenty of light, without the optic a single LED
will light our dressing room !!
I'm considering installing emergency/power cut lighting in key areas with
them.

The Farnell order code for the one I got is 432-5746

I'm trying to get pricing for the new Warm White Lumileds which should
give
a light closer to that of halogens
