Light Pipe Selector Guide Optopipe Lightpipes40 Years of LED Experience Why Light Pipes Visual status indication provides for safe and reliable operation of electrical equipment, instruments, and electronic devices and also serves diagnostic purposes as well. While lamp holders, which utilize sepa- rate incandescent or neon bulbs and lens caps, dominated the market in the majority of the 20th cen- tury, LED-based light sources are predominantly used today to provide visual indication. Technical Solutions Light-pipes provide front-panel indication where: Traditional indicators are too large or other space constraints exist Indication is required over, around, or beneath front-panel components EMI/RFI concerns require location of the light source away from the front-panel Indication is desired after all mechanical design considerations were made Index We also design light-pipes for non-diagnostic applications, including lighted company logos. 02 Product Overview Light loss between the LED and light-pipe interface must be considered and there is also additional transmission loss through the pipe or wherever there is a bend. The shape of the light-pipe also influences the output. Dialights design engineers will recommend the best LED for use with each light-pipe. Optopipe Lightpipes 04 PCB Mount Single Configuration and features Almost any configuration or size can be accommodated and we currently offer standard solutions in: Position Horizontal Single Element Round Lens Vertical Shielded Over RS-232 06 PCB Mount Multiple Multiple Element Square Lens Horizontal Textured Lens Over SFP Cage Position Vertical Single Row Rectangular Lens Vertical Right Angle Polished Lens Under PCB Mount 08 PCB Mount Multiple Multiple Row Illuminated Corner Horizontal Right Angle Position Horizontal Mounting Consideration 14 Panel Mount Single Most light-pipes are mounted to a PCB by pressing into holes drilled into the PCB. Depending on the appli- Position cation, epoxy is also indicated for additional support. Some light-pipes are designed to press into the front-panel and rest on the PCB, just above the LED(s). Heat-staking is another process that is used to mount light-pipes in specific applications. 15 Panel Mount Multiple position Micro LED LEDs 16 Recommended Micro LED Surface Mount LEDs New Products 18 Optopipe Lightpipe Actuator Extensions The following pages are organized as a product overview.
