What Are COB LED Strips?

COB LED strips utilize Chip on Board technology, where multiple LED chips are densely packed and encapsulated on a single circuit board, creating a uniform light-emitting surface. Unlike standard LED strips, which show visible LED dots (especially without a LED diffuser), COB strips produce a smooth, continuous glow that resembles a fluorescent tube but with the efficiency and flexibility of LEDs. This makes them ideal for applications where a polished, professional look is essential, such as under-cabinet lighting or architectural accents.

Recent advancements in COB technology include improved thermal management and integration with smart systems, as seen in upcoming products from brands like Philips Hue, which are reportedly developing COB-based light strips for enhanced seamless lighting. 

A typical COB LED strip setup includes:

• LED Chips: Hundreds of chips per meter for seamless illumination.
• Flexible PCB: Allows installation on curved or flat surfaces.
• Aluminum Profile: Acts as a LED heat sink and LED strip housing to protect the strip and enhance light diffusion.
• Diffuser Cover: Optional for softening light or reducing glare in LED strip light profiles.
• Mounting Accessories: Clips, brackets, or adhesive for secure LED lighting installation.

When housed in LED aluminum channels, COB strips gain added protection and a sleek, modern appearance, making them a favorite for both DIY and professional projects.

Pros and Cons of COB LED Strips

1. Dotless Lighting – Even Without Aluminum Profiles

One of the most common complaints with traditional LED strips is the visible “hot spots” where the LEDs are located. COB LED strips eliminate this issue. Even without using aluminum profiles or diffusers, COB strips provide a seamless, dot-free glow that looks clean and professional. This makes them ideal for applications where aesthetics are a priority.

2. Greater Flexibility

Thanks to their smaller diode size and even weight distribution, COB strips are more flexible than traditional SMD strips. The diodes are so closely spaced that bending and curving the strip is easier—perfect for installations in tight spaces, around curves, or for highlighting architectural details.

3. More Stable and Reliable

COB LED strips are built with direct chip-to-FPCB attachment, eliminating the delicate gold wires used in traditional SMD LEDs. This design reduces breakage risk and improves durability.

• Even if 1–2 chips fail, the high density (up to 480 chips per meter) ensures there’s no visible dark spot.
  
• The series-parallel circuit structure also ensures that partial failures don’t cause the whole section to go dark.
  

4. Wider Light-Emitting Angle

Traditional SMD strips have a 120° beam angle. COB LED strips widen this to 180°, reducing shadows and creating smoother, more even lighting.

5. Anti-Sulfurization Resistance

Without gold wire, COB LEDs avoid the sulfide reaction that can cause LED blackening and reduced brightness in SMD strips. This makes COB strips more reliable in environments where sulfur exposure is possible.

6. Stronger Anti-Static Capability

COB LED strips have better resistance to electrostatic discharge (ESD), protecting the internal electronics and extending their lifespan.

Cons of COB LED Strips

1. Difficult to Maintain Perfect Color Consistency

Currently, there’s no grading machine for COB LED strips, and manufacturers rely on sampling for quality control. This can result in slight variations in color temperature or hue, especially noticeable when adding new sections to an existing installation.

2. Lower Luminous Efficacy

The current luminous efficacy of COB strips is around 120 lm/W, which is lower than some high-performance SMD strips. This means they produce slightly less light per watt of energy consumed.

3. Power Limitation

The recommended maximum power for COB strips is 15W/m. Exceeding this can cause heat buildup due to the high chip density, which may shorten the product’s lifespan. While this is not a major drawback for most projects, it’s important to consider for high-brightness applications.
