Using plastic pipes to bring LED output to a front panel is not a new idea, but it’s a useful one, since it lets you use a surface-mount LED on your pc board and not worry about bending leads, mounting issues, etc. Bivar now offers a four-tier light pipe assembly so you can take four LED outputs to your panel. Their special design minimizes crosstalk between adjacent pipes.
With these four-channel light pipes, you can bring the output of multiple LEDs to your panel without optical crosstalk, while simplifying LED pc-board assembly issues.
The quad pipe assembly works with industry-standard LEDs including those from Bivar. The pipes measure 21.5 mm high by 21.4 mm in length, with a station width of 4.5 mm. You can get extended or recessed lens profiles to fit your application, and you can stack the pipes for even more LED piping in minimum space, if desired. The LP4 Quad-Level Light Pipe Series is priced at US$0.60.
