40 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
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.

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.

Dialight Optopipes®
Dialight’s expertise in LED indication and lighting is apparent in our line of engineered light-pipes. Dialight has been a
leading manufacturer of lightpipes for network communication and electronic equipment for more than 10 years. Our
200 standard and custom solutions are complemented by new designs resulting from customer requirements or market
developments. Dialight’s optical and mechanical engineers use the latest modeling tools to develop mechanical and
optical simulations that ensure expected performance of the design. SLAs are available to represent the physical and
optical characteristics of the design. Dialight also has an extensive optics lab for post-design measurement and analysis.
With various single and multiple position products for either Panel Mount or PCB Mount oriented lightpipes already in
production, we also have the added capability to manufacture custom solutions to meet your specific requirements.
