Working Principle & Dimming Technology
DC dimmers adjust light source brightness by modifying current or voltage, performing voltage conversion and stable current control. Two primary dimming technologies are employed:
- PWM (Pulse Width Modulation): Adjusts LED brightness by altering duty cycle to control average current
- Linear Dimming: Controls current through LED by modifying input voltage or current detection resistor resistance
Key Advantages
- Flicker-free & Silent Operation: Advanced PWM technology eliminates flickering and reduces noise
- High Efficiency: Exceptional reliability with extended operational lifespan
- Multi-Channel Common Anode: Supports multiple LED lamp configurations
- Precision Dimming: 0.1% adjustment accuracy for optimal lighting control
Application Scenarios
- Indoor Lighting: Residential, office, and commercial spaces
- Outdoor Lighting: Street, landscape, and public area illumination
- Automotive Lighting: Vehicle interior and exterior lighting systems
- Stage Lighting: Performance and event lighting solutions
- Advertising Displays: LED billboards and informational displays
- Smart Lighting: IoT-enabled lighting control systems
Installation Guide
With built-in driver, installation is simpler than standard dimmer switches (no additional LED driver required):
- GND (GREEN): Connect to ground wire in box
- V+ (RED): Connect to low voltage V+
- V− (WHITE): Connect to low voltage V−
- N (WHITE): Connect to 120 V Neutral
- H (BLACK): Connect to 120 V Line Hot
Troubleshooting
- Fixture does not illuminate:
- Check for incorrect wiring (polarity of Low Voltage V+ and V- may be reversed)
- Verify circuit breaker is ON and not tripped
- Ensure correct voltage pairing (12V dimmer won't power higher voltage fixtures)
- Dimming issues:
- Different fixtures not dimming in sync
- Fixture turns off at low dim level
- Fixture strobes/flickers at low dim level
- Excessive dimmer buzzing
- Fixture heats up excessively:
- Verify correct voltage pairing (don't attach 12V fixture to 24V dimmer)
- Check fixture compatibility
Note: Only install 12V or 24VDC tape lights on the compatibility list.
