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.
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.
