2025 Lighting Trends: The Surprising Rise of COB LED Strips-Why They’re Set to Dominate

In the evolution of lighting technology, COB LED strips shine as a groundbreaking innovation. With superior performance and sleek design, they unlock transformative lighting solutions for homes, businesses, and industries. Whether enhancing ambiance in living spaces or meeting strict commercial lighting standards, COB LED strips are rapidly becoming the go-to choice for modern illumination.

Technical Core: Chip-on-Board (COB) Technology

COB (Chip-on-Board) technology integrates hundreds of micro-LED chips directly onto a high-conductivity substrate (e.g., aluminum or ceramic PCB), replacing the discrete SMD beads in conventional strips. This eliminates gaps between light sources, achieving a seamless ‘glowing ribbon’ effect with 500-1000 chips per meter (vs. 60-120 in SMD). During production, multiple micro-LED chips are densely arranged on a flexible or rigid board, coated with a phosphor layer. This design creates seamless, spot-free lighting, unlike the “dotty” effect of conventional LEDs.

Key Advantages of COB Technology:

Smooth, Uniform Light: No visible gaps between light sources, resembling a glowing ribbon.

High-Density Chip Arrangement: Maximizes brightness and efficiency

Performance Advantages of COB LED Strips

Beyond CRI: Advanced Metrics

• TM-30-18: Evaluates color saturation and fidelity across 99 color samples.
• SSI (Spectral Similarity Index): COB LEDs score SSI >80, outperforming most SMD LEDs (SSI 60-75).

In the market, there are various styles of COB light strips that can meet the needs of different scenarios. In terms of voltage types, there are low-voltage and high-voltage light strips. The common voltages of low-voltage COB light strips are 12V and 24V. They have high safety, and it is not easy to get an electric shock even if the human body accidentally touches them. In areas with high safety requirements, such as home bedrooms and children’s rooms, it is more appropriate to use low-voltage light strips. For example, 24V low-voltage COB light strip has a large number of lamp beads per meter, emits light evenly and has no stroboscopic effect. When used for home lighting, it can create a comfortable and soft lighting environment. High-voltage COB light strips are generally 220V and can be directly connected to the regular household circuit without an additional transformer, and the installation is relatively simple. They are often used in some commercial places or outdoor landscape lighting that have requirements for installation space and wiring convenience, such as the sign lighting of some small shops and the linear lighting of outdoor garden paths.

Market Common COB Light Strips

According to the color effects, there are single-color, two-color temperature, RGB, and RGBW light strips. Single-color COB light strips provide light of a single fixed color, such as the common warm white light, neutral white light, and cool white light. Warm white light creates a warm and comfortable atmosphere and is suitable for home living rooms and dining rooms. Neutral white light is clear and bright and is often used in areas with high requirements for light brightness, such as kitchens and bathrooms. Cool white light has a bluish-white tone and can make the space look more open and bright, which is more common in some modern and simple commercial spaces. Two-color temperature COB light strips can switch between two color temperatures. For example, they can be switched between warm light and white light as needed to meet the lighting needs in different scenarios. For example, two-color temperature COB light strip can control the color temperature change through a remote control or a switch. Whether it is to create a warm atmosphere at night or to have bright light for activities during the day, it can be easily achieved. RGB COB strips leverage additive color mixing (Red/Green/Blue) with 16.7 million color options, controllable via DMX512 or Bluetooth apps. For studios, RGBW variants add a dedicated white diode (CRI 95+) for natural tones alongside vibrant hues and can be used to create dynamic and colorful lighting effects. They are often used in entertainment venues, themed restaurants, etc., adding fun and vitality to the space. RGBW light strips add a white light source on this basis, which can not only achieve richer colors but also simulate white light of different color temperatures, making the lighting effect more natural and real. They are widely used in places with extremely high requirements for lighting effects, such as high-end hotels and art exhibition halls.

In terms of waterproof performance, there are waterproof and non-waterproof styles. Non-waterproof COB light strips are suitable for dry and indoor environments, such as home indoor decoration and the internal display lighting of shopping malls. Since they have no additional waterproof design, the cost is relatively low, and the installation is more convenient. Waterproof COB light strips have undergone special waterproof treatment and can be used in humid or outdoor environments. Different waterproof grades also have different application scenarios. For example, IP65-grade waterproof light strips can prevent water jets and can be used for outdoor landscape lighting and the lighting in front of bathroom mirrors. IP67-grade waterproof light strips can be immersed in water for a short time, and they are suitable for scenarios such as the lighting around fountains and the underwater lighting of outdoor swimming pools.

What are the advantages and disadvantages of COB light strips compared with other types of light strips?

Compared with other types of light strips, COB light strips have advantages in aspects such as light emission effect and heat dissipation performance, but they also have some disadvantages in terms of cost, flexibility, etc. The details are as follows:
Advantages

• Good light emission uniformity: COB light strips adopt the on-board chip technology, directly fixing the LED chips on the circuit board. The chips are arranged closely with a small spacing, enabling a continuous and uniform light emission effect. Unlike traditional light bead type light strips, there will be no obvious light spots or dark areas due to the spacing between the light beads. In places with high requirements for light uniformity, such as museum display cases and the shelf lighting in high-end shopping malls, COB light strips can provide a better lighting environment.

• High brightness and high luminous efficacy: COB light strips usually adopt a multi-chip integrated design, and the brightness can be increased by adding the number of chips and optimizing the packaging process. At the same time, their luminous efficacy is also relatively high, which can more effectively convert electrical energy into light energy. Under the same power, the brightness of COB light strips is often higher than that of other types of light strips, making them suitable for occasions that require high-brightness lighting, such as industrial plants and parking lots.

• Excellent heat dissipation performance: The chips are directly connected to the circuit board, resulting in a short heat dissipation path. The heat can be quickly conducted from the chips to the circuit board and the heat dissipation device. Compared with traditional light strips, the temperature of the chips of COB light strips is lower during long-term use, which helps to reduce light decay and extend the service life. In some places that require long-term continuous lighting, such as hospitals and schools, the stability and durability of COB light strips are more advantageous.

• High color rendering degree: The color rendering index of COB light strips is usually relatively high, which can reach above 90, and some high-end products can even reach above 95. They can accurately restore the true colors of objects. For places with harsh requirements for colors, such as art galleries and photography studios, COB light strips can provide more accurate color lighting, showing the true color and details of objects.

Installation and Maintenance Key Points of COB Light Strips

(1) Installation Key Points

• Preparation of Installation Environment: Before installing the COB light strip, ensure that the installation surface is flat, dry, and clean, free of dust, oil stains, and other impurities to guarantee the adhesion or fixing effect of the light strip. If installing in an outdoor or humid environment, select a COB light strip with waterproof function, and make sure the installation location has good drainage conditions to prevent the light strip from being damaged by water accumulation.

• Determination of Installation Location and Length: Plan the installation location of the COB light strip accurately according to actual lighting needs. Measure the required length of the light strip, and use tools like scissors to cut it according to the cutting marks on the light strip. Be careful during cutting to avoid damaging the chips. If multiple sections of light strips need to be connected, use the matching connection accessories to ensure a firm connection and unobstructed circuit.

• Fixing and Wiring: Flexible COB light strips usually come with adhesive backing and can be directly pasted onto the installation surface. However, before pasting, conduct a power – on test on the light strip to ensure it emits light normally. When pasting, start from one end and press slowly to avoid air bubbles or wrinkles. Rigid COB light strips need to be installed using fasteners such as screws and clips. In terms of wiring, strictly follow the product instructions, correctly connect the positive and negative poles of the power supply to ensure safety and reliability. For those unfamiliar with circuit connection, it is recommended to have a professional electrician perform the operation.

(2) Maintenance Key Points

• Regular Cleaning: During the use of COB light strips, the surface is prone to adsorbing dust, which affects the lighting effect. Regularly wipe the surface of the light strip gently with a clean, soft damp cloth to remove dust and stains. But note that do not clean when the light strip is powered on to prevent the risk of electric shock. For stubborn stains, a small amount of mild cleaner can be used, but ensure that the cleaner will not corrode the light strip.

• Inspection of Connection and Fixing Conditions: Periodically check whether the connection parts of the COB light strip are loose and whether the fasteners are stable. If a loose connection is found, reconnect and reinforce it in time. For damaged or loose fasteners, replace or adjust them in time to ensure that the light strip will not be damaged by shaking or falling during use.

• Monitoring of Lighting Effect Changes: In daily use, pay attention to whether the lighting effect of the COB light strip is abnormal, such as a significant decrease in brightness, flickering, or some areas not lighting up. Once a problem is detected, promptly investigate the cause. If the problem is relatively simple, such as an individual lamp bead being damaged, try replacing the lamp bead. If it involves complex problems such as circuit failures, it is recommended to contact professional maintenance personnel for inspection and repair to avoid causing greater damage due to self – disassembly.

With its innovative technology, excellent performance, and wide application range, COB light strips are profoundly changing the landscape of the lighting industry. With the continuous advancement of technology and the gradual reduction of costs, it is believed that COB light strips will play an even more important role in the future of the lighting field, bringing people a higher – quality, more efficient, and more aesthetically pleasing lighting experience, illuminating every corner of life.
