What Is LED Bulb PCB?
LED bulb PCB is a specialized circuit board designed to power and control light-emitting diodes (LEDs) in lighting applications. It acts as the backbone, providing electrical connections, heat dissipation, and mechanical support for LED components. Unlike traditional bulbs, LED PCBs ensure energy efficiency, longer lifespan, and compact designs.
What Are the Advantages of LED Bulb PCB?
- High Energy Efficiency – Optimizes power use for brighter light with lower energy consumption.
- Thermal Management – Aluminum or ceramic substrates prevent overheating.
- Compact Design – Fits seamlessly into slim LED bulb housings.
- Long Lifespan – Robust materials ensure 50,000+ hours of operation.
- Customization – Flexible layouts for unique lighting requirements.

How to Design LED Bulb PCB Board?
Here are main steps of LED bulb PCB design:
Step 1: Circuit Design
- Schematic Creation: Use KiCad or Altium Designer to draft the circuit. Include LEDs, resistors, driver ICs (e.g., LM2596S), and power input ports.
- Component Selection: Choose SMD or COB, resistor values for current limiting, and thermal vias for high-power LEDs.
Step 2: PCB Layout Design
Component Placement:
- Arrange LEDs evenly for uniform illumination.
- Position driver ICs and resistors close to LEDs to reduce trace length.
Thermal Design:
- Use aluminum substrates or copper pours for heat dissipation.
- Add thermal vias under LED pads.
Trace Routing:
- Avoid sharp angles (use 45° bends) to minimize EMI.
- Ensure trace width matches current requirements (e.g., 20–30 mils for 1A).
Step 3: PCB Fabrication
DIY Method:
- Print circuit on glossy paper and transfer to copper-clad board via heat press.
- Etch with ferric chloride, drill holes, and clean the board.
Professional Fabrication:
- Submit Gerber files to manufacturers(such as Best Technology.)
- Select substrate material (FR4 for low power, aluminum for high power).
Step 4: Component Assembly
- SMD Soldering: Apply solder paste, place components with tweezers, and reflow with a hot-air gun.
- Through-Hole Soldering: Manually solder connectors and large components.
- Post-Assembly: Clean flux residues and inspect for cold joints.
Step 5: Electrical Checks&Operational Testing:
- Use a multimeter to verify voltage/current at key nodes (e.g., LED terminals).
- Test continuity to detect short circuits.
- Power the circuit and check LED brightness uniformity.
- Monitor temperature with an IR thermometer; ensure no overheating (>80°C).
