515-1071F, LED Light Pipe Round Right Angle Clear Rigid Bulk (25 Items)

Product Overview

The Dialight 515-1071F is a rigid, clear, round, right-angle LED light pipe designed for efficient light transmission from a surface-mount LED to a front panel. This component is typically used in electronic assemblies to provide visual indication without exposing the LED directly to the user interface. It ensures consistent light output and simplifies panel design.

Setup and Installation

Proper installation of the 515-1071F light pipe is crucial for optimal performance and light transmission. These light pipes are designed for specific PCB and panel layouts.

Preparation: Ensure the PCB (Printed Circuit Board) has the correct footprint for the LED and the light pipe's mounting pins. The front panel should have a precisely drilled hole for the light pipe's display end.
LED Alignment: Position the surface-mount LED on the PCB such that its light emission point aligns perfectly with the input end of the light pipe. Misalignment can significantly reduce light output.
Light Pipe Mounting: Insert the light pipe's mounting pins into the designated holes on the PCB. The right-angle bend should orient the display end towards the front panel opening. Ensure a secure fit to prevent movement.
Panel Integration: Once the light pipe is mounted on the PCB, align the PCB assembly with the front panel so that the display end of the light pipe protrudes through the panel opening. Secure the PCB assembly within the enclosure.
Testing: Before final assembly, power on the LED to verify that light is effectively transmitted through the light pipe and is visible through the front panel opening.

Note: Refer to the specific mechanical drawings and application notes provided by Dialight for precise dimensions and recommended PCB layouts.

Operation

The Dialight 515-1071F light pipe is a passive optical component. Its operation is directly dependent on the LED it is paired with. When the associated LED is illuminated, the light pipe transmits the light from the LED's emission point to the viewing surface, typically a front panel.

Light Transmission: The light pipe efficiently guides light through its clear, rigid body using total internal reflection.
Viewing Angle: The design provides a specific viewing angle for the transmitted light, optimized for direct viewing from the front of the panel.
Color: The color of the light displayed will be the color of the LED used. The light pipe itself is clear and does not alter the color.

No user interaction is required with the light pipe itself during normal operation, as it functions as a light conduit.

Maintenance

The Dialight 515-1071F LED light pipe requires minimal maintenance due to its robust and passive design. However, proper care can ensure its longevity and optimal light transmission.

Cleaning: If the exposed end of the light pipe on the front panel becomes dirty, gently wipe it with a soft, lint-free cloth. For stubborn dirt, a small amount of isopropyl alcohol can be used, applied to the cloth, not directly to the light pipe. Avoid abrasive cleaners or materials that could scratch the surface.
Inspection: Periodically inspect the light pipe for any signs of physical damage, such as cracks or severe scratches, which could impair light transmission.
Environmental Conditions: Ensure the operating environment adheres to the specified temperature and humidity ranges to prevent material degradation over time.

No internal maintenance or lubrication is required for the light pipe.

Troubleshooting

Most issues related to the light pipe's performance are typically associated with the LED or its power supply, or improper installation.

Problem	Possible Cause	Solution
No light visible from light pipe.	LED is not powered or faulty. Light pipe not aligned with LED. Light pipe is obstructed or severely damaged.	Check LED power supply and LED functionality. Verify light pipe and LED alignment during installation. Inspect light pipe for damage or obstructions; replace if necessary.
Dim or inconsistent light output.	Partial misalignment between LED and light pipe. Dust or debris on light pipe surfaces. Scratches or minor damage to light pipe. LED is underpowered or nearing end-of-life.	Re-check alignment. Clean light pipe surfaces gently. Consider replacement if damage is significant. Verify LED power supply and LED specifications.

If troubleshooting steps do not resolve the issue, contact Dialight technical support or your supplier for further assistance.
