In the LED world, COB is the abbreviation for Chip on Board, which basically means to package the LED die directly on the circuit board (PCB). The ‘Chip on Board’ LED used on flexible strip lights is also sometimes called a flip-chip.
The term LED is often found in association with other acronyms, as seen with SMD LEDs. The term COB LED refers to chip-on-board LED technology. This technology was introduced in 2011 and enabled the development of high-power diodes with a small light-emitting surface area.
Why should you choose COB or SMD LEDs? The introduction of COB LEDs has brought with it some significant advantages. First of all, the possibility of miniaturising the luminaires and the light sources inside them. COB technology facilitates the installation of individual plates in close proximity. This allows precise control of the distribution of the light beam thanks to the absence of space between one LED module and another. However, one application limitation of this technology is the power rating of the luminaire (possibly less than 50/70W) on which it is to be installed. SMD LEDs are to be preferred over COB technology precisely because they are more reliable and perform better in high powerapplications.
SLIM works with third-party companies to supply high-quality SMD LEDs. Among these companies is Luxelt, with the design and development of PCBs with high luminous efficiency and low power consumption SMD LEDs. These latest-generation SMD LEDs are used to develop customised lighting solutions for a variety of application areas, with particularly interesting projects in the HO.RE.CA, professional coffee machine and food equipment sectors.
