If you’ve ever tried lighting up a rounded bar counter or a wavy architectural feature, you know the headache. Traditional LED strips often buckle, create hot spots, or just don’t stick right. That’s where COB strips come in handy. COB, or Chip on Board, packs LEDs tightly on a single board for smoother light. But picking the right one for curves? It’s not as simple as grabbing the first roll off the shelf. In this post, we’ll walk through what to look for, drawing from real-world installs and tips from Raymates, a company that’s been in the LED game since 2009. They’ve got factories running with ISO9001 standards, and their products ship to over 30 countries. Let’s dive in.
How to Choose the Best COB Strips for Curved Surface Installations
What Makes COB Strips Ideal for Curved Surfaces?
Curved surfaces throw a wrench in lighting plans. Think about wrapping light around a hotel lobby’s arched ceiling or a car’s dashboard. Regular strips might leave shadows or warp. COB strips shine here because they bend without breaking the flow.
Uniform Light without Dots
COB strips ditch the dotted look of older SMD types. The chips sit close together, creating a seamless glow. In a recent project, Raymates used their strips on a bar countertop, and the marble lit up evenly—no dark patches. It’s like a continuous beam, perfect for spots where you notice every flaw.
High Flexibility for Bends
These strips use soft substrates like flexible PCBs, letting them curve up to certain radii without cracking. Raymates’ options handle bends down to 3cm radius. I’ve seen installs on cylindrical furniture where stiffer strips failed, but COB held shape. It saves time and cuts down on returns.
Durable Heat Dissipation
Good COB strips pull heat away fast, often with aluminum backs or thermal adhesives. Without it, LEDs dim quick. Raymates builds in heat sinks that keep things cool, extending life to 50,000 hours. In humid spots like kitchens, this prevents failures that plague cheap alternatives.
Which Raymates Products Excel in Flexibility?
Raymates started small in 2009 but grew fast, adding Sony SMT machines by 2013 for better output. Their COB lineup stands out for curves, with patents backing unique designs. Here’s a closer look at three that tackle bending head-on.
Super Long COB Strip Adaptability
This one’s a beast—up to 50 meters in one run. For large curved walls, like in a mall display, it bends smoothly without joints showing. Voltage options from 12V to 24V keep it stable, and the high-density chips ensure no sagging light over distance.
Mini Size COB Strip Narrow Fit
At just 3mm to 5mm wide, this strip squeezes into narrow grooves on curved edges. Picture lighting a rounded shelf in a jewelry store; it fits without bulky profiles. Raymates offers it in warm whites, hitting CRI over 90 for true colors on gems.
Colorful COB Strip Vibrant Options
RGB versions let you switch hues, ideal for dynamic curves in clubs or events. It bends like the others but adds tunable whites from 2700K to 6500K. A client used it on a bridge perimeter—50m glow without fading, even outdoors.
How Do Voltage and Power Affect Curved Installs?
Power setup can make or break a curved job. Too much voltage, and wires overheat on bends. Too little, and light dims at the end. Raymates tailors theirs for balance, drawing from years of global exports.
Low Voltage for Safe Bends
Stick to 12V or 24V for most curves—it runs cooler and safer, especially in homes. Higher volts like 220V suit straight runs but risk shorts on twists. Raymates’ low-volt COB avoided issues in a hotel corridor wrap-around.
Balanced Power for Even Glow
Aim for 10-15W per meter to avoid hot spots. Overpower, and curves warp from heat. Raymates caps theirs smartly, like 10W/m on the Mini Size, keeping glow steady on a 20m curved cabinet.
Customizable Options from Raymates
Need specific volts or watts? Raymates does ODM, adjusting for your curve. In one case, they modded a 36V version for an art gallery’s irregular frame, cutting energy use by 20% while matching the bend.

What Installation Features Simplify Curved Setups?
Curves demand easy fixes, or you’ll spend hours fighting tape. Raymates packs features that cut install time, based on feedback from installs worldwide.
3M Adhesive for Secure Hold
Strong backing like 3M tape grips curves without rebound. Cheaper tapes peel off, but this holds on wood or metal. A bar project saw zero slips after months, thanks to Raymates’ standard 3M.
Cuttable Units for Custom Fits
Markings every 50mm let you snip without killing the circuit. For a wavy countertop, trim to match contours exactly. Raymates designs theirs with safe cut points, avoiding shorts that ruin batches.
Solderless Connectors for Quick Links
Clip-ons join sections fast, no soldering mess on site. For curves, this means seamless runs. Raymates includes them, speeding up a bridge lighting job from days to hours.
How Can Waterproof Ratings Protect Curved Applications?
Moisture wrecks LEDs on exposed curves. Rain or steam—pick the right IP rating, or watch your install fail. Raymates certifies theirs with UL and CE for tough spots.
IP20 for Indoor Curves
Basic protection suits dry indoors, like curved furniture. It’s lightweight, bending easy without bulky seals. Raymates’ IP20 COB lit a kitchen island arc perfectly, no fogging.
IP65 Upgrades for Outdoor Use
Silicone coats block splashes, great for garden curves or signs. Holds up in Saudi heat or French rain—Raymates exports there. A park railing install stayed bright through storms.
Raymates Waterproof Treatments
Custom silicone or epoxy adds IP67+ for harsh curves. In food plants, this fights condensation. One client avoided rewires by choosing Raymates’ treated strips.
Which Applications Benefit Most from Raymates COB Strips?
Raymates’ strips pop up in diverse spots, from hotels to bridges. Their 2023 sales doubled, showing trust in curved challenges.
Arc-Shaped Cabinet Lighting
In stores, arcs highlight shelves. Raymates’ Mini COB fits snug, with high CRI showing clothes true. A cosmetics counter glowed evenly, boosting sales.
Irregular Decorative Edges
Think wavy walls in bars or KTVs. Colorful COB adds vibe without gaps. Raymates powered a club setup, changing colors on curves for parties.
Automotive and Art Frameworks
Dashboards or sculptures curve tricky. Super Long COB wraps frames, with low volt for safety. An art install used it on twisted metal, lasting years.
How to Ensure Longevity in Curved Installations?
Curves stress strips, so aim for builds that last. Raymates hits 50,000 hours with low decay, backed by TUV certs.
High CRI for Consistent Color
Over 90 CRI keeps hues steady on bends. Fading colors ruin displays—Raymates maintains it, like in gallery arcs where art pops.
Low Light Decay Standards
L70 rating means 70% brightness at life end. Heat on curves accelerates decay, but Raymates’ dissipation keeps it low. Tests show under 10% drop in 10,000 hours.
Raymates Certified Durability
UL, ETL, RoHS—global stamps mean safe curves worldwide. From 2015 certs to 2020 patents, they back products. Clients report zero failures in curved spots after years.
Wrapping up, choosing COB for curves boils down to flexibility, power smarts, and tough builds. Raymates delivers with real-world wins. Check their site for quotes—might just solve your next bend.
