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

We also design light-pipes for non-diagnostic applications, including lighted company logos.

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. Dialight’s design engineers will recommend the best LED for use with each light-pipe.

Configuration and features

Almost any configuration or size can be accommodated and we currently offer standard solutions in:

Mounting Consideration

Most light-pipes are mounted to a PCB by pressing into holes drilled into the PCB. Depending on the appli-

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.
