What is Double Row COB LED Strip?

A Double Row COB LED Strip features COB (Chip on Board) technology where chips are densely arranged in two parallel rows on the PCB (Printed Circuit Board). This dual-row design offers several advantages:

Enhanced Brightness: With two rows of LEDs, the strip can produce more brightness at the same power level compared to a single-row design.

Improved Heat Dissipation: The dual-row layout allows better heat distribution across the strip, which minimizes the risk of overheating and improves the strip's longevity.

Uniform Light Output: Double-row COB LED strips reduce visible spots or "hot spots" often seen with single-row strips, resulting in smoother, more even lighting. This uniformity is ideal for applications where seamless light quality is required.

Extended Durability: Effective heat management from the double-row design enhances overall stability, making these strips suitable for continuous or long-term use in areas like commercial displays, ambient lighting, or architectural applications.

Products Details

01.Wide Viewing Angle

The COB LED strip offers a viewing angle of up to 180 degrees, compared to the typical 120-degree angle in standard SMD LED strips. 

This is achieved by placing the chip directly on the PCB and covering it with phosphor, which results in fewer dark spots and a broader light spread.

02.Excellent CCT Uniformity for Continuous Orders

With an experienced engineering team, we maintain exceptional Correlated Color Temperature (CCT) consistency across continuous orders, 

achieving a 3-step MacAdam ellipse (3 SDCM) for color uniformity. This ensures that each order will match in color temperature and brightness,

delivering reliable and consistent quality to customers.

 

03.22 AWG Pure Copper Wire

We use high-quality 22 AWG pure copper wire for connectivity. Each LED strip end is stripped to 3/8 inches for easy wiring, 

focusing on durability and effective power transmission.

Custom LED Strip Supplier & Manufacturer

LEDWorker is a leading manufacturer and supplier of high-quality LED strip lights, specializing in customized solutions for residential, commercial, and industrial applications. Our automated production lines ensure product consistency and quality, enabling us to provide reliable, energy-efficient lighting solutions. We offer extensive OEM and ODM services, tailoring LED strips to meet specific requirements such as LED density, PCB width, color temperature, and waterproofing level.

Our commitment to quality is underscored by certifications, including CE and RoHS, ensuring safety and environmental friendliness. With competitive pricing, flexible order quantities, and a dedicated support team, LEDWorker is a trusted partner for all LED strip lighting needs.

Customizing LED Strip Components:

1. Customizing LED Quantity:
Based on customer requirements, the number of LEDs per meter can be adjusted. Changing the density of LEDs affects the strip's lighting effect, with higher densities providing better linearity. Additionally, adjusting the arrangement of LEDs impacts the brightness and voltage drop across the strip, allowing for tailored lighting performance.

2. Customizing PCB Boards:
LED strips can have customized PCB boards to suit different installation environments. For narrow spaces, thinner strips can be produced, while for higher brightness needs, wider PCBs may be used to enhance heat dissipation. Moreover, double or triple-row LED arrangements can be achieved by expanding the PCB width to deliver the desired lighting effects.

3. Customizing Waterproofing:
Depending on the intended usage environment, various waterproof levels can be applied. For instance, IP20 indicates no waterproofing, IP65 is gel-coated, and IP67 uses tubing or extrusion methods for waterproofing. For outdoor applications like neon LED strips, IP67 is commonly used, and IP68 offers the highest level of waterproofing with considerations for plug and cable sealing to ensure complete water resistance.

This level of customization ensures that clients get the most suitable LED strip solutions for their specific projects, whether for indoor decor or demanding outdoor lighting installations.

4. Customizing Color Temperature:

We offer standard color temperatures of 3000K, 4000K, 6000K, 8000K, and 10000K. Additionally, we can customize specific color temperatures based on customer requests. In certain environments, strict requirements for color temperature are essential. If customers provide the x and y chromaticity coordinates on the color spectrum chart, we can produce a color that precisely matches their needs.

This level of customization ensures that lighting solutions not only meet aesthetic preferences but also adhere to technical specifications for specialized environments.

5. Custom Color Steps:
Our standard offering for LED strip products is three-step color binning, ensuring consistency in light output. However, if customers require finer precision, we can provide a one-step binning process, which guarantees even tighter control over color consistency.

6. Custom Color Rendering Index (CRI):
Some customers require specific CRI (Color Rendering Index) standards. Achieving a CRI of 90 is relatively straightforward with current LED technology. However, for higher CRI values, like 95, we need to determine if the requirement is for an average CRI or if specific parameters like R9 (which represents red tones) must also be high. A CRI of 95 or higher is typically needed in specialized environments like photography studios. We can fully meet customer demands for CRI, ensuring optimal color accuracy for any application.

7. Custom Packaging:
Single-color LED strips are often used for home and commercial decor, and we provide packaging customization to cater to wholesalers. This includes custom labels, special bags, boxes, and display stands, offering a one-stop service experience for our clients.

What does COB mean for LED strips?

LED lights in the cob refers to the LED lights used in the COB light source, COB full chip On board.

COB light source is the LED chip directly affixed to the high reflectivity of the mirror metal substrate on the high luminous efficiency of the integrated surface light source technology.

What is the difference between SMD and COB LED strips?

SMD (Surface-Mounted Device): This method packages each LED chip into a separate “bulb” or module (SMD) that is then mounted onto a PCB. SMD LEDs typically have larger spacing between each light point, which may create a more noticeable dotting effect.

COB (Chip on Board): In COB LEDs, chips are mounted directly onto the PCB without individual modules, allowing for a continuous and seamless line of light. COB strips usually appear more uniform and are suitable for creating smooth lighting with less noticeable dotting.

What is the maximum length of a COB LED strip?

Single-row COB LED strips: Maximum length is usually around 5 meters (for single-end power input).

Double-row COB LED strips: Can reach lengths of 50 to 70 meters depending on the power supply and configuration, with constant current options extending this up to 30 meters without significant voltage drop
