2. Setup and Wiring
Proper wiring is crucial for the correct operation and longevity of your LEDs. These are common cathode bi-color LEDs, meaning the negative terminal (cathode) is shared between the two colors (red and green).
Identifying Pins:
- The longest lead is the Common Cathode (-).
- The other two shorter leads are the Anodes (+) for the Red and Green colors. You may need to test to identify which anode corresponds to which color.
Connecting Resistors:
LEDs require a current-limiting resistor to prevent damage from excessive current. Connect a resistor in series with each anode (+) pin of the LED before connecting to your positive voltage source. The included resistors are suitable for DC 6-12V power supplies.
- For Red LED (Forward Voltage 2.0V): Use a 470 ohm resistor for 6-12V applications.
- For Green LED (Forward Voltage 3.0V): Use a 430 ohm resistor for 6-12V applications.
- Important: Always use a current-limiting resistor. Applying voltage directly without a resistor will damage the LED.
Wiring Diagram (Conceptual):
Connect the common cathode to the negative terminal of your power supply. Connect each anode, through its respective resistor, to the positive terminal of your power supply. To illuminate a specific color, apply voltage to its corresponding anode. To illuminate both, apply voltage to both anodes simultaneously.
3. Operating Instructions
Once properly wired with the appropriate resistors, these bi-color LEDs can be operated by applying the specified DC voltage.
- Single Color Illumination: Apply positive voltage (through a resistor) to the anode corresponding to the desired color (Red or Green). The common cathode should be connected to ground (negative).
- Mixed Color Illumination: To achieve a mixed color (e.g., orange or yellow-green), apply positive voltage (through resistors) to both the Red and Green anodes simultaneously. The resulting color will be a blend of red and green light.
- Voltage Range: The LEDs are designed for operation with DC 6-12V when used with the provided resistors.
- Current: Optimal forward current (IF) is 20mA.
4. Maintenance
These LEDs are robust and require minimal maintenance. Follow these guidelines for optimal performance and longevity:
- Storage: Store LEDs in a dry environment, away from direct sunlight, high temperatures, and excessive humidity.
- Cleaning: If necessary, gently clean the LED lens with a soft, dry cloth. Avoid abrasive materials or harsh chemicals.
- Soldering: When soldering, limit exposure to heat. For manual soldering, keep soldering time under 3 seconds at temperatures between 482°F (250°C) and 527°F (275°C). For reflow soldering, keep exposure under 5 seconds at 500°F (260°C).
5. Troubleshooting
If your LED is not functioning as expected, consider the following common issues:
- LED Not Lighting Up:
- Check power supply: Ensure the power supply is providing the correct DC voltage (6-12V).
- Verify polarity: Confirm the common cathode is connected to ground (-) and the anode(s) to the positive voltage (through resistors).
- Resistor connection: Ensure resistors are correctly wired in series with each anode. An LED without a resistor will likely burn out immediately.
- Loose connections: Check all solder joints and wire connections.
- Incorrect Color or Dim Light:
- Resistor value: Ensure the correct resistor value is used for the applied voltage. Incorrect resistor values can lead to dimness or overcurrent.
- Anode identification: Re-verify which anode corresponds to Red and which to Green.
- Damaged LED: If the LED was previously connected without a resistor or to excessive voltage, it might be damaged.
- Resistors Getting Hot:
- This can occur if the resistors are operating near their maximum power rating, especially with 12V. While the included 1/4 Watt resistors are generally suitable, for continuous operation at 12V and 20mA, consider using 1/2 Watt resistors for increased safety margin.
