- Drive Circuit Requirements : Needs constant current source for optimal performance
## 2. Design Considerations
### Common Design Pitfalls and Solutions
Current Regulation Issues
- Pitfall : Direct connection to voltage source without current limiting
- Solution : Implement constant current driver circuit (20mA recommended)
- Implementation : Use dedicated LED driver IC or current-limiting resistor calculated as R = (V_supply - V_f) / I_f
Thermal Management Problems
- Pitfall : Overheating due to inadequate heat dissipation in enclosed spaces
- Solution : Ensure proper ventilation and consider thermal derating above 60°C ambient
- Implementation : Include thermal relief pads in PCB design and maintain minimum clearance
ESD Vulnerability
- Pitfall : Electrostatic discharge damage during handling and installation
- Solution : Implement ESD protection circuits on drive lines
- Implementation : Use TVS diodes or ESD protection ICs on all signal lines
### Compatibility Issues with Other Components
Power Supply Compatibility
- Incompatible with unregulated power supplies exhibiting voltage spikes
- Requires clean DC power supply with <100mV ripple
- May require additional filtering when used with switching power supplies
Microcontroller Interface
- Compatible with 3.3V and 5V logic levels
- Requires buffer circuit when driving from high-impedance microcontroller pins
- PWM dimming compatible with frequencies up to 1kHz
Mechanical Integration
