Thermal Optimized

Flex PCB for LED Lighting

Illuminate any shape with flexible LED circuits. From architectural accent lighting to automotive applications, our LED flex PCBs deliver the flexibility, thermal performance, and reliability that modern lighting demands.

Flex PCB for LED Lighting

LED lighting has revolutionized illumination, and flexible circuits have revolutionized LED lighting. The ability to bend, curve, and conform to any surface has enabled lighting designs that were impossible with traditional rigid boards.

Flexible LED circuits are now found everywhere - from the backlighting in your car dashboard to architectural installations that curve around buildings. The combination of LED efficiency with flex PCB adaptability creates endless possibilities for lighting designers.

Our LED flex PCB solutions address the unique challenges of lighting applications: thermal management to ensure LED longevity, consistent current distribution for uniform brightness, and construction options from basic strips to sophisticated addressable systems with per-LED control.

LED Lighting Applications

Flexible LED circuits illuminate countless applications.

Architectural Lighting

Cove lighting, facade illumination, and accent lighting use flex LED strips to follow architectural curves and highlight design features.

Automotive Lighting

Interior ambient lighting, door sill illumination, and custom exterior accents use flex circuits to conform to vehicle contours.

Display Backlighting

Edge-lit and direct-lit backlighting for monitors, TVs, and signage rely on uniform flex LED arrays.

Commercial & Retail

Shelf lighting, display case illumination, and brand signage use flex LED for consistent, attractive lighting.

Residential

Under-cabinet lighting, closet illumination, and decorative accents bring LED flexibility to homes.

Horticultural

Grow light arrays use flex LED circuits for uniform light distribution across growing areas. Specific wavelength optimization available.

LED flex PCB applications

Thermal Design

Heat management is critical for LED longevity and performance.

Standard Copper

For lower power applications, standard 1oz or 2oz copper provides adequate heat spreading for most indoor LED strips.

Heavy Copper

2oz to 4oz copper weight increases current capacity and thermal performance for higher power LED applications.

Aluminum Core

Aluminum-backed flex provides excellent thermal conductivity (1-3 W/m·K) for high-power LED arrays. Essential for COB and high-density applications.

Thermal Interface

Design includes considerations for thermal interface between flex circuit and heat sink. Proper mounting maximizes heat transfer.

Current Distribution

Trace width and routing optimize current distribution across LEDs. Consistent current means consistent brightness and color temperature.

LED Types & Integration

Different LED types require different circuit approaches.

SMD LEDs (2835, 5050, 5730)

Standard surface-mount LEDs in common packages. Single color and RGB versions available. Established supply chain and competitive pricing.

Mini & Micro LED

Smaller LED packages for higher resolution displays and finer pitch applications. Tighter tolerances on pad placement.

COB (Chip-on-Board)

Direct die bonding for highest lumen density. Requires excellent thermal management. Used for high-output fixtures.

Addressable LEDs

WS2812B, SK6812, and other addressable LEDs enable individual pixel control. Three-wire or four-wire interfaces for control and power.

High CRI LEDs

CRI 95+ LEDs for color-critical applications. Optimized driving and thermal design maintains color consistency.

Frequently Asked Questions

What is the maximum length for continuous LED flex strips?

Standard production supports continuous lengths up to 5 meters. Longer lengths are possible with power injection points. We can advise on optimal segmentation for your design.

Do you offer assembled LED strips or bare flex circuits?

We offer both bare flex circuits and fully assembled LED strips. Assembly includes LED placement, current limiting resistors, and connector termination.

What waterproofing options are available?

We support IP20 (no protection), IP65 (silicone coating), IP67 (silicone tube), and IP68 (silicone-filled tube) ratings. Selection depends on installation environment.

Can you produce aluminum-core flex for LEDs?

Yes, we offer aluminum-backed flexible circuits for maximum thermal performance. These are essential for high-power LED applications requiring efficient heat dissipation.

What LED packages do you support?

We support all standard SMD packages (2835, 3528, 5050, 5630, etc.), mini/micro LEDs, COB mounting, and addressable LEDs. Custom packages can be accommodated with design review.
