In a previous query from about a year ago witih the subject "LEDs in
Series with LM334 Current Source" (search google groups for background)
I was getting some good help. I've built a prototype but now need to
get some prototype boards made. My test samples are just too unwieldy
to deal with any further.
http://www.frontiernet.net/~miketoni/images/tbird/prottype.jpg
Looking around, the maximum size of many of many houses that deal with
low quantities is smaller than the piece I need. My board needs to be
about 16" long and only about 4/8ths of an inch wide. This board
basically has LED's attached to it for insertion into a mount and lens
on a automotive tail light.
Can anyone point me to a company that might be able to deal with my
need of a long board in low quanties, i.e. inexpensive?
BTW - I'm using a LM334z with a 2N3906 transistor and a 2.7ohm reistor
to set the current at a nice solid 19mA. the LM334z is providing
excellent regulation with a current rise of only about 2% within a
voltage range of 12.6v to 25v. Should protect the LED's quite well.
Thanks.
