ASMTLED COB LED Strip Lights User Manual

1. Introduction

Thank you for choosing ASMTLED COB LED Strip Lights. This manual provides essential information for the safe and efficient installation, operation, and maintenance of your LED strip lights. These high-density, flexible COB (Chip-on-Board) LED strips offer superior brightness, uniform illumination, and high color rendering (Ra>90) without flickering, making them ideal for various lighting applications.

2. Package Contents

Your package should contain the following:

• 1x 5-meter or 10-meter COB LED Strip

Note: Power supply or adapter is NOT included and must be purchased separately.

3. Setup and Installation

3.1 Safety Precautions

• Ensure the power is off before installation.
• Use only DC12V or DC24V power supplies as specified for your strip. Connecting to incorrect voltage will damage the strip.
• Do not bend the strip sharply at the LED components.
• The strip is IP44 rated, meaning it is protected against solid objects larger than 1mm and splashing water from any direction. It is not waterproof for submersion.
• The strip operates at low voltage and is touchable when working.

3.2 Preparation

• Unroll the LED strip completely before testing or prolonged use to prevent overheating.
• Ensure you have a compatible DC12V or DC24V power supply (transformer/adapter) with sufficient wattage for the length of your strip.
• Clean the surface where the strip will be mounted to ensure proper adhesion.

3.3 Installation Steps

Figure 3: Key features for installation: flexibility, adhesive, and cut points.

1. Cutting the Strip (Optional): The COB LED strip is cuttable at designated marks. For 480LEDs/m strips, you can cut every 50mm. For 312LEDs/m strips, you can cut every 38.44mm. Ensure you cut only at the marked lines to avoid damaging the circuit. The remaining LED strip will still function.
2. Adhesion: The strip comes with strong 3M double-sided adhesive tape on the back. Peel off the protective backing and firmly press the strip onto the clean, dry surface.
3. Wiring:
   • Direct Connection (via Power Supply): Connect the positive (+) and negative (-) wires of the LED strip to the corresponding output terminals of your DC12V/24V power supply. Ensure the power supply is then connected to an AC 110V-220V source.
   • Adapter Connection: If using a DC adapter, connect the LED strip's wires to the adapter's output plug (typically a barrel jack connector). Ensure polarity is correct. The adapter then plugs into a standard AC outlet.

   Wiring Diagram Description: The installation diagram illustrates two common wiring methods. The first shows multiple LED strips connected in parallel to a central DC power supply, which then connects to AC 110V-220V. The second method shows a single LED strip connected to a DC adapter, which plugs directly into an AC outlet.

4. Testing: Once wired, turn on the power to test the strip. If it doesn't light up, check all connections and polarity.

4. Operating Instructions

4.1 Power On/Off

Simply switch on the power supply connected to the LED strip to turn it on, and switch it off to turn it off.

4.2 Dimmability

These LED strips are dimmable. To adjust brightness, you will need a compatible DC dimmer switch (not included) installed between the power supply and the LED strip.

4.3 Color Temperature

Your COB LED strip is available in various color temperatures:

• 3000K: Warm White (a cozy, yellowish light)
• 4000K: Nature White (a neutral, balanced white light)
• 6000K: White (a cool, bright white light)

5. Maintenance

• Cleaning: Ensure the strip is powered off and cool. Gently wipe the strip with a soft, dry cloth. For stubborn dirt, slightly dampen the cloth with water (do not use harsh chemicals or abrasive cleaners).
• Inspection: Periodically check the adhesive for secure attachment and inspect wiring connections for any signs of wear or damage.
• Storage: If storing the strip, keep it in a cool, dry place, away from direct sunlight and extreme temperatures.

6. Troubleshooting

• Strip Not Lighting Up:
  • Check if the power supply is correctly connected and receiving power.
  • Verify that the LED strip's positive (+) and negative (-) wires are connected to the correct terminals on the power supply.
  • Ensure the power supply voltage (DC12V or DC24V) matches the strip's requirements.
  • Check for any loose connections or damaged wires.
• Partial Lighting or Dim Sections:
  • Inspect cut sections to ensure they were made correctly at the designated marks.
  • Check for any physical damage or kinks in the strip.
  • Ensure all connections are secure.
• Flickering:
  • Ensure your power supply is stable and provides sufficient wattage for the length of the strip.
  • Check for loose connections.
  • If using a dimmer, ensure it is compatible and functioning correctly.

8. User Tips

• Optimal Brightness: For best results, ensure the LED strip is placed in a location that allows its high brightness to be fully utilized, such as under cabinets, cove lighting, or accent lighting.
• Power Supply Matching: Always use a power supply that matches the voltage of your LED strip (DC12V or DC24V) and provides sufficient wattage for the total length of the strip you are using.
• Surface Preparation: A clean, dry, and smooth surface is crucial for the 3M adhesive to bond effectively and prevent the strip from peeling off over time.
