What is COB LED STRIP
A COB LED strip (Chip On Board) is a type of LED strip where LED chips are directly bonded onto a printed circuit board (PCB). Unlike traditional LED strips, which use individual LED packages, COB LED strips involve placing multiple tiny LED chips directly on the PCB surface. A layer of phosphor-encapsulated glue is then applied over the chips to diffuse light and provide a uniform glow. This process results in dot-free illumination, with a wide beam angle of 180°, offering smooth, consistent lighting with no visible individual LED dots.
Key Features of COB LED Strips:
- Dotless Lighting: The chips are densely packed, resulting in a smooth, continuous light output with no visible hot spots or dots.
- Wide Beam Angle: The strips emit light at a 180-degree angle, making them perfect for applications requiring wide-area lighting.
- Flexible and Customizable: COB LED strips are available in various PCB widths (ranging from 3mm to 12mm), voltages (5V, 12V, and 24V), and LED densities (320 to 840 LEDs per meter).
- High Color Rendering Index (CRI): With a CRI of 90+, COB strips provide excellent color accuracy, making them ideal for applications requiring high color fidelity.
- Color and Temperature Options: Available in multiple colors, including warm and cool white (2700K-6000K), RGB, and special colors like red, green, blue, and yellow.
- Durability: COB LED strips have a lifespan of up to 50,000 hours and can be made waterproof (IP20 to IP68), suitable for indoor and outdoor use.
Advantages of COB LED Strips:
-
Cost Efficiency: COB LED strips use flip-chip technology, which offers a cost advantage when using the same number of LED chips compared to other LED strips like SMD.
-
Better Heat Dissipation: The heat dissipation path is shorter, resulting in lower thermal resistance, which reduces light decay and extends the strip's lifespan.
-
No Visible Light Spots: COB LED strips feature continuous phosphor encapsulation, which eliminates visible light spots, providing smooth and soft illumination, ideal for creating a DOT-FREE lighting experience. This is particularly effective when installed in aluminum channels, where other types like 2835, 5050, or 2110 would show visible light dots.
- Lighting Angle: COB strips offer a wide beam angle of 180 degrees, ensuring broader light coverage.
- No Silver Plating: Eliminates the risk of vulcanization.
Disadvantages of COB LED Strips:
- Color Consistency: Achieving uniform color consistency is harder compared to SMD LED strips. In SMD production, LED chips undergo a binning process for consistent color matching, while COB involves directly applying phosphor over the chip on the PCB, making it harder to control uniformity.
- Lower Power: Due to the dense arrangement of chips, COB LED strips have limited heat dissipation, capping their power output at around 14W per meter, while SMD strips can go up to 18W or higher.
- Lower Luminous Efficiency: COB LED strips generally have lower luminous efficiency, with a maximum of around 100LM/W. In contrast, high-power SMD LED strips can reach up to 160-170LM/W. Therefore, for brightness above 120LM, high-brightness SMD LED strips may still be required.
- Durability Issues: COB LED strips are more prone to damage from repeated bending or pulling, especially during the manufacturing of waterproof versions. The chips are directly embedded onto the PCB, and the small size makes them more vulnerable to detachment, resulting in dead LEDs.
COB LED Strip Application
COB LED strips are becoming increasingly popular in various lighting applications due to their uniform light distribution and dot-free appearance. Here are some of the key areas where COB LED strips are widely applied:
COB LED strips provide smooth, even lighting, making them perfect for creating ambiance and adding depth to spaces. They are commonly used in:
- TV background walls: For soft backlighting that reduces eye strain while watching TV.
- Ceilings and cove lighting: To highlight architectural features and create a warm, inviting atmosphere.
- Cabinet lighting: Ensuring consistent illumination across shelves without visible light spots.
- Staircase lighting: Enhancing safety while adding an aesthetic touch.
- Vanity mirrors: Ideal for vanity mirrors due to their high CRI and spot-free illumination, making them a popular choice among manufacturers of vanity lighting.
n commercial environments like shopping malls and hotels, COB LED strips are utilized to enhance the visual appeal and create distinct lighting layers:
- Display lighting: Provides uniform, high-quality lighting for showcases and display cases, ensuring products are well-lit and visually appealing.
- Architectural outlines: They are often used to outline building facades and highlight specific architectural elements.
- Landscape lighting: COB LED strips in warm colors are frequently used to enhance landscapes, such as trees, lakes, and building contours, adding a warm, inviting glow.
COB LED strips are popular in entertainment venues like KTVs, nightclubs, and bars for their ability to create dynamic visual effects and high brightness levels. These strips are used to:
- Enhance ambiance with colorful lighting that syncs with music.
- Create unique lighting effects that elevate the overall experience for customers.
