“COB” describes a mounting technique for LED chips that places them in direct contact with the substrate to create LED arrays. Compared to earlier LED technologies, such as SMD and DIP, COBs provide a variety of advantages. The LED array may be packed more densely with COB technology, or “light engineers refer to lumen density”. As a result, light has a higher intensity and is more uniform. Using COB LED technology can also save space and energy while maintaining the same light output. Compared to SMD or DIP LED Arrays, a 500-lumen COB-based LED array may be up to 100 times smaller and use a fraction of the power of the latter two options.
With COB LED technology, you may use as many diodes as you like because there is just one circuit and two contacts on the whole chip. This single circuit design simplifies the entire LED device regardless of the number of diodes on the chip.
Chip-on-Board LED arrays provide several advantages, including:
- Compactness is a result of the chip’s diminutive size.
- Incredibly intense at close ranges.
- Consistent quality even at short distances
- Reduced complexity due to using a single circuit and just two connections.
- more excellent durability, stability and reliability due to improved thermal performance
When running on battery power, why are COB LEDs so crucial?
Battery-powered lighting systems have always had to choose between lumen output quality (i.e. brightness) and runtime in their design. It is customary to have shorter runtimes for brighter images (assuming you use the same size battery). COB LED technology has made this trade-off considerably less of a problem. Low-wattage COB LEDs, for the first time, can provide exceptionally high-quality, incredibly brilliant light. Tiny and lightweight lithium-ion batteries can run COB-based LED lighting systems for lengthy periods since they are relatively small and lightweight. Due to this, COB-based LED lights were the only viable option.
Before putting in the lights for some events, we must ensure that we have the appropriate lighting equipment for each location. This includes lighting for hotels and restaurants and lighting for fashion shops. The following are some tips for selecting the proper COB light for the right spot:
CRI and CCT
They choose the correct CRI, CCT, and light source for the diverse environments. High-lumen COB lights should be used in parking lots, shopping malls, living rooms, and exhibition halls, where the CCT ranges from 3000k to 5000k, Ra 80.
Luminous Power and Angle of Emission
The application scenario, layout design, and the number of lights will define the luminaire’s power and light-emitting angle. Ground and work surfaces’ height and lighting needs also affect light-emitting angle and power. The next step is to select a mould for COB once the above considerations have been made. For 9MM luminous surface COB, it is better to use 30W below 15° of angle, 20W is better for 6MM, 15W is better for 4MM, and 10W is better for 3MM based on great angle and large light-emitting surface COB. 4MM luminous COB and 3MM luminous COB can reach angles below 10°.
The Effect of Heat Dissipation
The luminaire’s heat sink tests whether the heat dissipation system is effective. If the heat dissipation structure or the COB and optical solutions aren’t enough, you’ll need to make changes.
