New Bright Pipes optical light pipes from CML Innovative Technologies (CML-IT) produce bright, even indication based on optical ray tracing. Suitable for transferring light from a PCB to a front panel, the devices conveniently and economically conduct light from SMT LEDs through angles and distances to a viewable front lens surface. This provides attractive illumination, for example, of equipment function status (eg on/off) with minimal attenuation of light output through the optical fibres between the LED light source and the lens front.
