What is a COB light strip?

COB light strip is an LED light strip manufactured using COB (Chip on Board) technology. COB technology integrates multiple LED chips on a substrate and realizes the connection between lamp beads through connecting lines, thereby achieving high brightness, High uniformity and high energy efficiency. This makes COB light strips have higher brightness and better color reproduction, and are more energy-saving than traditional LED light strips.

What are the advantages of COB LED strips?

The brightness of COB light strips is very high. One meter of COB light strips can reach a brightness of more than 2,000 lumens, which is enough to meet the lighting needs of many large commercial and industrial places. At the same time, COB light strips also have a wider range of use scenarios and can be used in home lighting, commercial lighting, indoor and outdoor lighting and other occasions.

COB light strips also have excellent color reproduction, allowing people to see more realistic and natural colors. The color temperature range of COB light strips is also very wide. You can choose the color temperature suitable for different occasions, such as warm white (K-K), natural white (K-K) and cool white (K-K).

In addition, COB light strips also have better uniformity and anti-interference. Due to its high chip density, the light is more uniform and there will be no "dots forming lines". During use, COB light strips are also more resistant to interference and more sensitive to changes in voltage, current and other factors.

What are the disadvantages of COB LED strips?

The disadvantage of COB light strips is that the price is relatively high, and due to the high chip density, their product prices are usually more expensive than traditional LED light strips.

Larger heat: Due to the large number of COB lamp bead chips, the heat generated is also relatively large. If there is no heat dissipation design, it will affect the life of the product.

Susceptible to voltage fluctuations: Each LED chip in a COB lamp requires stable current and voltage. If the power supply is unstable, it will have an adverse impact on brightness and lifespan.

Taken together, COB light strips have some advantages and disadvantages compared to traditional LED light strips. Although the price is relatively high, COB light strips are still irreplaceable in high-demand lighting needs such as commercial and industrial places. lighting solutions.

COB LED Strip Lights: Explained

COB, which stands for Chip On Board, refers to a type of LED strip light where the LED chips are mounted directly onto the circuit board (PCB). This differs from traditional SMD (Surface Mounted Device) LED strips where the chips are housed in individual packages and sold onto the PCB.

Here's a breakdown of the key characteristics of COB LED strip lights:

Advantages of COB LED Flex Strips

1. No Visible LED Dots

- COB LED flex strips deliver uniform light output without the LED dot effect, even without using aluminum profiles. This results in a cleaner and more consistent light appearance, enhancing the aesthetics of any space.

2. Enhanced Flexibility

- These strips are exceptionally flexible, allowing for creative installations in various settings. They can be incorporated into intricate designs and tight spaces where traditional LED strips might not fit, offering customized lighting solutions that wrap around curves and fit into narrow alcoves.

3. Increased Stability and Fewer Issues

- COB LED strips use direct chip attachment to the Flexible Printed Circuit Board (FPCB), eliminating the need for gold wires, which are common points of failure in traditional SMD LED strips.

- The unique circuit design, with chips connected in parallel as groups and then in series, ensures the strip remains illuminated even if some chips fail.

- High chip density (up to 480 chips per meter) ensures uniform illumination, preventing dark areas if a few chips fail.

4. Wide Emitting Angle

- With a 180-degree beam angle, COB LED strips provide broad and even light distribution. This is ideal for task lighting, ambient lighting, and highlighting large surfaces, eliminating shadows and dark spots.

5. Anti-Vulcanization

- Designed with materials that resist vulcanization, COB LED strips maintain their flexibility and integrity over time, even in challenging environments, extending both their aesthetic and functional life.

6. Stronger Anti-Static Capability

- COB LED strips have a stronger anti-static capability, reducing the risk of damage from static electricity. This helps protect the electronic components and extends the lifespan of the lighting solution.

Disadvantages of COB LED Flex Strips

1. Inconsistent Color Without Binning

- Maintaining consistent color across different batches can be challenging, as COB LED strips do not use the BINNING machine process. This can result in slight variations in color temperature and hue, noticeable when adding new sections to an existing installation.

2. Lower Luminous Efficiency

- COB LED strips may have lower luminous efficiency compared to some high-power traditional LED strips. They may produce less light per watt of energy consumed, though the superior light quality and uniformity often outweigh this factor for many applications.

3. Lower Power Output

- Typically operating at lower power levels compared to some traditional LED strips, COB LED strips might not be suitable for projects requiring intense illumination levels. However, they provide ample light for most residential and commercial settings, creating inviting and well-lit spaces.

Types of COB LED Strips

COB LED strips come in a variety of configurations to suit different lighting needs. Here's a breakdown of some key factors to consider when choosing COB LED strips:

Chip Density:

• This refers to the number of LED chips mounted per meter of strip length. Higher chip density translates to brighter and more even illumination but might also consume more power. Common options include: Low Density (60-120 chips/meter): Suitable for accent lighting or creating a soft glow. Medium Density (180-300 chips/meter): Ideal for general lighting and task lighting. High Density (360-480 chips/meter): Provides very bright and even light, often used for under-cabinet lighting or task lighting requiring high intensity.

Color Temperature:

Similar to traditional LED strips, COB strips come in various color temperatures, affecting the perceived "warmth" or "coolness" of the light:

• Warm White (K-K): Creates a cozy and inviting atmosphere, ideal for residential settings.
• Neutral White (K-K): Offers a balanced light suitable for kitchens, bathrooms, or workspaces.
• Cool White (K-K): Provides a bright and energizing light, often used in commercial spaces or task lighting.

Voltage:

COB strips typically operate on either 12V or 24V DC power.

• 12V strips are commonly used for smaller projects or DIY applications due to their ease of use with low-voltage power supplies.
• 24V strips are better suited for longer runs or high-power installations as they experience less voltage drop over extended distances.

Waterproof Rating:

COB strips can be categorized based on their water resistance:

• Non-waterproof: Ideal for indoor applications with no exposure to moisture.
• IP65: Protects against water jets and dust, suitable for damp locations like bathrooms or kitchens.
• IP67/IP68: Fully submersible, perfect for outdoor use or areas with direct water exposure.

PCB Width:

The width of the printed circuit board (PCB) can influence the flexibility and installation options for the strip:

• Narrow PCB (2mm-5mm): Offers greater flexibility for tight spaces or curved surfaces.
• Wide PCB (8mm-12mm): Provides more space for additional features like integrated heat sinks or higher chip density.

Additional Considerations:

• Color Rendering Index (CRI): This metric indicates a light source's ability to accurately reveal the colors of objects. COB strips with a high CRI (above 90) are ideal for applications requiring good color perception, such as retail displays or art galleries.
• Dimming Capability: Some COB strips offer dimming options for adjusting light intensity to create different moods or ambiences.

By understanding these types and factors, you can choose the most suitable COB LED strip lights for your specific project requirements.
