When lighting designers tackle curved surfaces, sharp bends, and non-linear architectural details, traditional straight LED strips often fall short. That’s why S-shape (zig-zag) LED strips are transforming how we light architectural signage, furniture, and creative spaces. Their unique layout enables designers to follow arcs, wrap corners, and achieve fluid, seamless lighting without compromising performance.
At Yiholight, we see S-shape strips as a powerful tool in flexible LED design — and here’s why.

What Exactly Is an S-Shape LED Strip?
An S-shape LED strip features a flexible printed circuit board (PCB) arranged in a zig-zag or “S” pattern, rather than a straight line. This design gives the strip built-in flexibility, allowing it to bend laterally (side-to-side) and conform to curves, tight corners, and unusual geometries.
Yiholight’s LED-strip catalog illustrates how our standard 2835 and 3528 strips are “ultra-slim and flexible… bendable, making them easy to install in narrow spaces, curves, and edges.” Yiholight’s S-shape strip series extends that flexibility, offering both design freedom and reliable performance.
Why S-Shape Strips Matter — The Key Advantages
Design Versatility & Flexibility
The zig-zag layout makes S-shape strips ideal for curved signage, channel letters, and creative backlighting. Designers can follow contours without soldering multiple straight segments. This saves time and ensures a smoother visual flow.
Seamless Illumination
Because of its layout, an S-shape strip maintains more even LED spacing when bent. This reduces dark gaps or hot spots, delivering a continuous, uniform glow — a major advantage for architectural lighting.
Space Efficiency
S-shape strips are often narrower (e.g., 6–8 mm) than rigid strips, and their flexible form allows them to tuck into tight channels, letter enclosures, or shallow extrusions. This makes them well suited for compact or intricate installations.
Durable Mechanical Performance
Zig-zag PCBs distribute stress across the strip rather than concentrating it in one direction. This reduces fatigue and helps the strip withstand repeated bends, which is crucial for curved or dynamic installations.
Installer Convenience & Cost Savings
Because the strip itself handles bends, installers need fewer connectors or solder joints. That means lower labor costs, fewer failure points, and faster deployment.
Who Benefits Most from S-Shape LED Strips?
- Signage Makers & Channel Letter Fabricators: Perfect for illuminating letters that curve or have tight shapes.
- Architects & Lighting Designers: Great for accent lighting on curved coves, ceilings, and architectural forms.
- Retail & Commercial Spaces: Use zig-zag strips to highlight display cases, curved walls, or artistic installations.
- Furniture Designers: Integrate soft glowing lines into curved desks, counters, or decorative furniture.
- DIY Makers & Makerspaces: Ideal for creative lighting experiments and custom shapes without complex soldering.
When & Where to Use S-Shape LED Strips
When to Specify Them:
- During design phases for signage, lighting artwork, or custom lighting projects.
- For retrofitting existing curved structures that require lighting integration.
- When you want clean aesthetics without multiple joints or connectors.
Where They Shine:
- Architectural Signage: Illuminating channel letters, logos, and signs with curved edges.
- Cove Lighting: Following non-linear ceiling or wall coves with no visible breaks.
- Furniture: Under shelves, behind curved backrests, or inside sculptural furniture.
- Interior Accent Lighting: Around curved walls, arches, or decorative design elements.
How to Choose and Install S-Shape LED Strips
Review Technical Specs
Voltage: Many Yiholight strips support 12V or 24V.
Cutting length: Confirm the strip’s recommended cut interval to maintain S-shape consistency.
CRI: Choose higher CRI options (e.g., 90+) for accurate color rendering. Yiholight’s strip range often features CRI ≥ 90.
Plan the Layout
Map out curves, corners, and paths.
Avoid too-tight bends; check the manufacturer’s recommended bend radius.
Mount Securely
Use 3M adhesive tape, clips, or aluminum channels.
For curved shapes, select mounting accessories that allow for flexibility.
Power Wisely
Determine required driver power based on total strip length.
Use quality constant-voltage drivers.
Test Before Finalizing
Power up short sections as you go to ensure consistent brightness.
Once installed, test at full brightness and check for voltage drop.
Weather & Protection
If the strip will be outdoors, choose waterproof (IP-rated) variants.
Use proper housing or diffusers for protection and aesthetics.
