Use direct indicators when the LED can be placed near the enclosure opening. Use light pipes when the LED must be mounted deep on the PCB to route light to a specific panel location.
Circuit Board Indicators, Arrays, Light Bars, Bar Graphs Component Intelligence
Precision visual feedback components for board-level status and monitoring.
What are Circuit Board Indicators, Arrays, Light Bars, Bar Graphs components?
These components provide essential visual status, diagnostics, and level monitoring directly on the PCB. Selection hinges on mechanical orientation (vertical vs. right-angle), luminous intensity requirements, and thermal management for high-density arrays.
How to Choose Circuit Board Indicators, Arrays, Light Bars, Bar Graphs Components
Select based on mechanical constraints and optical requirements to ensure reliable status indication.
Mechanical Orientation
Choose between vertical, right-angle, or surface-mount housings based on enclosure clearance and viewing angle.
Optical Output
Match luminous intensity (mcd) and wavelength to ambient lighting conditions and user interface requirements.
Array Configuration
Select bar graphs or multi-LED arrays for linear level indication; verify segment pitch and common cathode/anode wiring.
Thermal Management
For high-density arrays, ensure the PCB layout supports adequate heat dissipation to prevent premature LED degradation.
Drive Requirements
Verify forward voltage (Vf) and current (If) match your driver circuit to ensure consistent brightness across all segments.
