18W DOB LED Light Driver Board MCPCB integrates the driver and LEDs onto one aluminum plate. Each 18W unit draws 220-240V AC to produce 6500K light. This 10-pack supplies components for bulk LED bulb repair or DIY builds.
Key Features
- Integrated DOB Layout: Driver circuitry sits directly on the LED mounting plate. Fits into standard bulb housings without extra wiring.
- Aluminum MCPCB Substrate: Metal core construction pulls heat away from the SMD chips. High humidity environments require this thermal management to prevent diode failure.
- 6500K Light Output: 18W diodes produce 6500K Cool Day Light color temperature. Replaces dim or yellowed plates in existing light fixtures.
- Direct AC Input: Terminals accept 220-240V AC input without an external transformer. Simplifies wiring during the LED bulb repair process.
Frequently Asked Questions
What is DOB in LED bulbs?
Driver on Board (DOB) places the voltage regulation circuit directly on the LED plate. This removes the need for a separate bulky capacitor driver inside the bulb base.
How to repair 18W LED bulb at home?
Desolder the wires from the old plate and solder them to the L and N terminals on this MCPCB. Apply thermal paste behind the board to manage heat during operation.
