What's the COB light strip?
WellShow
In the LED lighting industry, COB (Chip on Board) light strips are gradually becoming a popular choice in the high-end lighting market.
Compared with the traditional SMD (Surface Mounted Device) light strips, COB light strips excel in terms of high brightness,uniform illumination, and no graininess, and have achieved remarkable success in areas such as home decoration, commercial lighting, and film and television shooting.
Today, we will delve into the characteristics, application scenarios and purchasing tips of COB light strips, aiming to help you better understand this lighting "black technology".
Different widths of COB
COB vs SMD: Key Differences
WellShow
Different light emission principles
SMD: Multiple independent LED chips are soldered onto a flexible circuit board, with a certain distance between each LED. Therefore, the light spots are distinct and have a "granular" feel.
COB: Utilize the "direct chip packaging" technology. The LED chips are densely arranged and covered with fluorescent gel, resulting in more uniform light emission, without a granular feel, and the light is soft like a "light blanket".
2. Application Scenarios
COB: Suitable for high-end home decoration (without main lighting design), cabinet lighting, museum display, and film and television lighting, etc., in scenarios requiring high color rendering and no flicker.
SMD: Applicable to basic decorative lighting, such as background walls, ceiling light channels, etc., for cost-sensitive projects.
Advantages of COB Light Strips
WellShow
1. Particle-free light, providing a more comfortable visual experience
The LED particles in traditional SMD light strips have a significant spacing, while the light from COB light strips is continuous and uniform. This makes them particularly suitable for scenarios requiring high-quality lighting environments, such as bedrooms, study rooms, and high-end retail stores.
2. High Color Rendering Index (CRI ≥ 90)
COB light strips usually use high-quality LED chips, with a color rendering index (Ra) of over 90. They can accurately reproduce the colors of objects and are suitable for places with high color requirements such as art galleries, clothing stores, and makeup rooms.
3. Flexible and bendable, with flexible installation
The COB light strips are made with high-density packaging, yet they remain flexible and can be easily attached to curved walls, round furniture, and other complex structures, meeting the needs of creative lighting.
4. Low heat generation, longer lifespan
Due to the optimization of the heat dissipation structure by the COB technology, the temperature of the light strips during operation is lower, and their lifespan can exceed 50,000 hours, far exceeding that of ordinary LED light strips.
5. Support intelligent dimming
Most COB light strips are compatible with PWM dimming or DALI protocols, and can be integrated with smart home systems to achieve continuous adjustment of color temperature and brightness, creating personalized lighting ambiance.
Installation precautions
WellShow
1.Avoid excessive bending:Although the COB light strips are flexible, repeated bending may damage the circuit.
2.Control the installation length:It is not recommended to exceed 5 meters for a single light strip; otherwise, the brightness at the end may decrease.
3.Use with aluminum troughs:If you need long-term high-brightness operation, it is recommended to add an aluminum trough for heat dissipation to extend the lifespan.
