COB LED Strip Light

BrightLink COB LED Strip Light — Seamless, Dot-Free Linear Illumination

COB (Chip-on-Board) technology represents the next evolution in LED strip lighting. Instead of discrete LED packages spaced along a flexible circuit, COB strips pack hundreds of tiny LED chips directly onto the PCB in a continuous line, then encapsulate them in a uniform phosphor layer. The result: a seamless ribbon of light with zero visible dots — even without a diffuser or aluminum profile.

For designers, architects, and lighting specifiers who demand the cleanest possible light line, BrightLink’s COB LED strips eliminate the spotted appearance that plagues traditional SMD strips in visible installations. Whether mounted in exposed aluminum channels, behind translucent diffusers, or in tight coves where the light source is partially visible, COB strips deliver the smooth, continuous glow that defines premium architectural lighting.

Key Features & Benefits

• 100% Dot-Free Light Output — The continuous COB chip array and phosphor coating produce a perfectly uniform light line with no hot spots or individual LED dots visible, even at close viewing distance or through thin diffusers.
• Wide 180-Degree Beam Angle — Broader light distribution than SMD strips (180 degrees vs 120 degrees), providing more even wall-wash and ambient illumination with fewer visible edges.
• Superior Thermal Performance — The direct-chip-on-board construction eliminates thermal resistance from LED packaging, running cooler at the chip junction and extending operational life beyond 50,000 hours.
• Flexible Bending Radius 30mm — Despite the dense chip array, the strip remains highly flexible, bending around curves with a minimum radius of just 30mm for circular, arched, and organic-shaped installations.
• Tunable White Options Available — Beyond fixed 3000K/4000K/6500K, we offer tunable white COB strips that adjust from warm to cool via a compatible CCT controller — perfect for spaces that need to adapt throughout the day.
• Cuttable Every 16.7mm (24V) / 25mm (12V) — Dense cut points allow precise length customization for cabinetry, furniture, and architectural features where exact measurements matter.

Technical Specifications

Typical Applications

• Exposed Architectural Linear Lighting — Mount in visible aluminum channels on walls, ceilings, and columns where the light source itself becomes a design element — the dot-free glow creates a premium, minimalist aesthetic.
• Furniture & Cabinet Integration — Install inside display cabinets, wardrobes, and shelving where the strip may be directly visible to users. No diffuser needed, saving space and cost.
• Retail & Luxury Hospitality — The seamless light line elevates the perceived quality of hotel lobbies, boutique stores, jewelry displays, and high-end residential interiors.
• Mirror & Vanity Lighting — Wrap around bathroom mirrors or install in vanity frames for even, shadow-free illumination ideal for grooming and makeup application.
• Stair & Handrail Accent Lighting — The ultra-thin, flexible strip conforms to curved handrails and stair profiles, providing safety illumination with a refined visual appearance.

Installation Notes

COB strips generate slightly more heat per unit length than SMD strips due to the higher chip density. Always mount on aluminum profile channels for heat dissipation, especially for ceiling and enclosed installations. Connect to a constant-voltage LED driver matching the strip voltage. For runs over 5m (12V) or 7.5m (24V), inject power at multiple points. Cut only at the marked scissors lines. Avoid bending at sharp angles — maintain minimum 30mm bend radius.
