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.

While both types of LED strips light are commonly used for various lighting applications, they differ significantly in terms of their structure, performance, and suitability for different uses.
By highlighting the key differences between SMD and COB LED strips, this article aims to empower readers to make informed decisions when selecting the right LED strip technology for their specific lighting needs.
What is an SMD LED Strip?
SMD (Surface Mounted Device) LED technology represents a type of LED (Light Emitting Diode) that utilizes surface-mounted technology to optimize space utilization.
Unlike traditional LEDs employing through-hole technology (THT), where LED leads are inserted into drilled holes in the PCB, SMD LEDs feature LED chips soldered directly onto the surface of a printed circuit board (PCB).
Key Features of SMD LED Strips:
- Enhanced Beam Angle: Through the clustering of multiple LED chips, SMD LED Strips achieve a wider beam angle, ensuring uniform light distribution.
- Cost-Effectiveness: SMD LED Strips typically offer a more cost-effective solution than traditional LEDs, attributed to their reduced power requirements and prolonged lifespan.
What is a COB LED Strip?
A COB (Chip on Board) LED strip represents a specialized form of LED strip leveraging chip-on-board technology to directly mount multiple LED chips onto a substrate, typically a printed circuit board (PCB).
This innovative approach allows for a higher density of LED chips, offering several notable advantages over conventional LED technologies such as SMD (Surface Mounted Device) LEDs.
Key Features of COB LED Strips:
- Compactness: COB LED strips boast a more compact design attributed to the diminutive size of the chip and the close arrangement of LED chips.
- High Intensity: COB LEDs emit light of higher intensity, particularly when viewed at close distances.
- Uniformity: COB LEDs provide superior uniformity of light, ensuring consistent illumination even at close working distances.
- Design Simplicity: With a simpler design comprising only one circuit and two contacts for the entire chip, COB LEDs offer streamlined functionality regardless of the number of diodes.
- Superior Thermal Performance: COB LEDs exhibit enhanced thermal performance, resulting in prolonged lifespan, heightened stability, and improved reliability.
Key Differences Between SMD and COB LED Strips
COB, or chip on board, entails the direct packaging of the chip onto the PCB. A COB LED strip encapsulates chips on a flexible board, representing a novel process technology. Its internal structure comprises PCB, phosphor, package chip, and gold wire.

SMD, or surface mount device, LED strip lights are among the most prevalent LEDs on the market. These LEDs feature chips permanently fused to a printed circuit board (PCB), renowned for their versatility. The internal structure encompasses PCB, printed circuit board, solder joints, brackets, phosphorescent packages, chips, and gold wires.
The COB chip emits light directly from the bottom, without any obstructions, enabling a light-emitting angle of up to 180 degrees.
In contrast, the patch LED strip includes a bracket, limiting its light-emitting angle to 120 degrees. The presence of the bracket influences the quality of light produced. Notably, the two technologies differ in the number of diodes, impacting brightness and light range.
COB LED strips emit uniform and glare-free light, whereas SMD LED strips produce glare, making them best suited as dot light sources. Flexibility distinguishes the COB LED strip, which is soft and capable of withstanding significant deformations, facilitating easy shaping as required. Moreover, the COB LED strip boasts easy installation in confined spaces, aided by strong adhesive properties.
In contrast, achieving spotless light with SMD LED strips necessitates compatibility with aluminum profiles. Conversely, COB LED strips can achieve this effect without aluminum profiles. If you're seeking a lighting supplier for your project, consider the unique attributes of both technologies to meet your specific requirements.
