Introdução

The LED light bulb consists of many small LEDs connected in series. Whenever a single LED gets fused, the circuit is broken and the Light bulb stops functioning, even though most of the LEDs are still in working condition.

Use this guide to repair a fused bulb by easily replacing a fused LED with a new LED and completing the closed circuit through which the current flows again and lights the bulb.

  1. Remove the upper semi-sphere diffuser by twisting or applying some heat with a heat gun or dryer to soften the adhesive. Remove the upper semi-sphere diffuser by twisting or applying some heat with a heat gun or dryer to soften the adhesive.
    • Remove the upper semi-sphere diffuser by twisting or applying some heat with a heat gun or dryer to soften the adhesive.

  2. Use a battery or a cell with connecting wires and apply them to the exposed solder ends on each LED. The LED which doesn't lights up is detected as the faulty LED. The LED which doesn't lights up is detected as the faulty LED.
    • Use a battery or a cell with connecting wires and apply them to the exposed solder ends on each LED.

    • The LED which doesn't lights up is detected as the faulty LED.

  3. Using a knife or screwdriver, remove the faulty LED.
    • Using a knife or screwdriver, remove the faulty LED.

    • We need to replace it with a similar LED or a resistor.

    • Connecting the terminals directly can result in an increased current and multiple LED failure.

  4. Using the soldering iron solder an LED or a 100Ω (2W or 5W) resistor into the faulty LED space. Using the soldering iron solder an LED or a 100Ω (2W or 5W) resistor into the faulty LED space.
    • Using the soldering iron solder an LED or a 100Ω (2W or 5W) resistor into the faulty LED space.

  5. Connect the bulb to a power source to detect if it's working.
    • Connect the bulb to a power source to detect if it's working.

  6. Finally, twist the light-diffusing dome back on the light bulb. Finally, twist the light-diffusing dome back on the light bulb.
