COB LED Strip Light-Technology, Applications & Project Solutions

Continuous, dot-free linear lighting solutions engineered for professional lighting projects and architectural applications.

What Is COB LED Strip Light?

COB LED strip light (Chip on Board) is a linear lighting solution designed to deliver continuous, dot-free illumination. By integrating multiple LED chips directly onto the PCB and covering them with a uniform phosphor layer, COB LED strips provide smooth and visually comfortable lighting, even at close viewing distances.
 
COB technology is often referred to as FCOB LED strip, where LED chips are mounted directly onto a flexible PCB (FPCB). This structure eliminates visible light points commonly found in traditional SMD LED strips, making COB LED strips especially suitable for linear lighting, aluminum profiles, and architectural applications

Technical Parameters Overview

Before selecting a COB LED strip for your project, it is important to understand the following parameters:

  • Voltage options
  • Power range (W/m)
  • Color temperature options
  • CRI levels
  • PCB width & cutting length
  • Standard reel length

Insufficient experience with COB technology often leads to inconsistent brightness, color deviation, or long-term reliability issues.

Waterproof & Customization Options

COB LED strip lights are available with different IP protection levels to meet various installation environments and project requirements.

  • IP20 (Non-Waterproof) Designed for dry indoor environments, IP20 COB LED strips are commonly used in aluminum profiles, cabinets, shelves, and architectural linear lighting applications where no direct exposure to moisture is expected.
  • IP65 (Waterproof) IP65 COB LED strips are coated with a silicone protection layer, making them suitable for humid areas and indirect outdoor applications. They can withstand light water exposure but are not intended for full submersion.

Different IP options allow lighting designers and project planners to select the most appropriate solution based on installation conditions, durability requirements, and visual performance.

Installation Principles & Key Notes

While installation methods vary by project, COB LED strips generally follow these principles:

  • Install on clean, heat-dissipating surfaces
  • Use appropriate power supplies
  • Avoid excessive bending or tension
  • Ensure proper thermal management

How to Choose a Reliable COB LED Strip Manufacturer in China

When sourcing COB LED strip lights from China, importers and project buyers should focus on more than just pricing. A reliable manufacturer should demonstrate:

  • Stable COB packaging technology and consistent light output
  • Clear electrical and optical specifications (CRI, CCT, power, lumen output)
  • Proven experience in COB LED strip production, not only SMD strips
  • Strict quality control processes and aging tests
  • Support for customization, compliance, and export requirements
  • Choosing a manufacturer with real production capability and project experience helps reduce quality risks and ensures long-term supply stability.

Insufficient experience with COB technology often leads to inconsistent brightness, color deviation, or long-term reliability issues.

FAQ

Is COB LED strip suitable for low-profile aluminum channels?

Yes. COB LED strips are widely used in low-profile aluminum channels because of their continuous, dot-free light output. 

However, power density and heat dissipation should still be evaluated based on the installation length and operating environment to ensure long-term stability.

The recommended power range depends on the application.

For accent and decorative lighting, lower power options are usually sufficient.

For functional or architectural lighting, higher power levels may be required, but thermal management and power supply matching should be considered during project planning.

Yes. COB LED strips can be customized in terms of voltage, power, CCT, CRI, PCB width, cutting length, and IP rating.

Customization feasibility and lead time depend on technical requirements and order volume, and should be evaluated at the early project stage.

COB LED strips with IP65 protection are suitable for humid areas and indirect outdoor applications.

They can withstand light water exposure but are not designed for full immersion.

For harsher outdoor environments, additional protection or alternative lighting solutions should be considered.

Before starting a project, it is recommended to confirm application type, installation method, required brightness, power supply configuration, and environmental conditions.

Clear technical alignment at the early stage helps reduce design changes and ensures smoother project execution.
