Basic knowledge of COB light strip to share
Sharing the Basics of COB Light Ribbon, Onboard Chip (COB) LEDs are relatively new compared to the LED market and offer many advantages over standard options. COB LEDs are basically multiple LED chips (usually nine or more) bonded directly by the manufacturer to the substrate to form a single module. Since the individual LEDs used in the COB are chips and not traditionally packaged, the chips can be mounted so that they take up less space and the highest potential of the LED chip can be obtained. When the COB LED package is powered up, it looks more like a single lighting panel than multiple individual lights, compared to the case of using multiple tightly mounted SMD LEDs.
COB strip light 1, product advantages
With a multi-chip package, the luminous area of a COB LED can contain many times more light sources in the same area that a standard LED might occupy, resulting in a significant increase in lumen output per square inch. COB LEDs use a single circuit with only two contacts to power the multiple diode chips they contain. This reduces the number of components required for proper operation per LED chip. In addition, fewer components and the removal of the traditional LED chip structure package can reduce the heat generated by each LED chip. When coupled to an external radiator, the ceramic/aluminum substrate of the COB LED can also be used as a more efficient heat transfer medium, further reducing the overall operating temperature of the component.
COB strip light 2, product radiator
When installing a COB into a radiator, care must be taken to select a radiator that dissipates the heat generated so that the COB can reach its full potential. In the long run, proper heat dissipation can improve efficiency and reduce failure rates. Another aspect of COB LEDs that reduces the failure rate is that since each chip is mounted directly on the substrate, there is no need to spot weld the individual LED chips. The fewer the number of weld spots, the lower the failure rate. Because the lenses and other traditional LED wrappers are no longer in place when COB LEDs are used, light loss is significantly reduced and the viewing Angle is increased.
COB strip light 3, the application of lighting
COB LEDs have a wide range of applications. While these devices can be used for higher output conventional lighting, the primary use of COB LEDs is as a solid state lighting (SSL) alternative to metal halide lamps in high shed lighting, street lighting and high output applications such as tracking lights and downlights.
COB strip light 4, improve lumen output
The use of COB LEDs in lighting applications is increasing as designers realize the benefits of using COB LEDs compared to traditional standard LED options. Due to the ability to pack more LED light sources into a smaller space to improve lumen output, the ability to transfer heat to the radiator more efficiently, and due to their simple construction, lower failure rate, lower light loss and larger viewing Angle, it is difficult to not consider them in any lighting application design.
