## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Incurrent Current Limiting
- Problem : Direct connection to voltage source without current limiting damages LED
- Solution : Implement series resistor calculated using R = (V_supply - V_f) / I_f
Pitfall 2: Inadequate Heat Management
- Problem : High ambient temperatures reduce LED lifespan
- Solution : Ensure proper ventilation and derate current at elevated temperatures
Pitfall 3: Poor Viewing Angle Alignment
- Problem : Indicator not visible from required viewing positions
- Solution : Conduct viewing angle analysis during panel layout design
### Compatibility Issues
Electrical Compatibility:
- Requires compatible DC power supply (typically 5V, 12V, or 24V systems)
- Incompatible with AC power without additional rectification circuitry
- Ensure voltage regulator stability to prevent flickering
Mechanical Compatibility:
- Panel cutout requirement: 8mm circular hole
- Verify panel material compatibility with mounting mechanism
- Check clearance behind panel for LED depth (15.5mm)
Optical Compatibility:
- Consider ambient lighting conditions when selecting LED intensity
- Verify color recognition requirements for specific applications
### PCB Layout Recommendations
Power Supply Considerations:
- Place current-limiting resistor close to LED terminals
- Implement decoupling capacitor (100nF) near power connections
- Use adequate trace width for expected current (≥0.5mm for 20mA)
Signal Integrity:
- Route indicator lines away from high-frequency signals
- Implement ground plane for noise reduction
- Consider ESD protection for externally accessible indicators
Mechanical Layout:
- Allow sufficient clearance around mounting area (≥2mm)
- Ensure panel mounting doesn't stress PCB connections
- Consider service access for replacement
