COB stands for "Chip On Board".
It is possible to say that COB LEDs became available in the lighting market in about 2007. Initially the market was sceptical about the benefits of COB LEDs because the way they are constructed allowed LED manufacturers to put extremely high powered light sources in small package.Like a lot of new technologies, there were teething problems, mainly associated with heat management and thermal resistance. though now several lifetime tests have shown that COB packages are very reliable, if heat management is done properly.
These issues have now been thoroughly resolved as demonstrated by the modern reality that every contemporary major LED manufacturer and package maker has COB LEDs as part of their product range.
What are the advantages?
COB packages present excellent uniformity of light from light emitting surface. This is important especially if you want to avoid multiple shadow effect, which often occurs with SMD based lighting solutions. COBs also display superior light distribution. The fact that they are a single light source results in longer battery life, so they are far more economical & better for the environment. From a technical perspective, COB LEDs are also much easier to test. You only need a COB LED constant current driver and a heat sink such as a piece of aluminium.
It is clear that COB LEDs have been very important development in the LED lighting business. This great innovation has allowed an increase in the potential power which can be used inside one LED package by an exponential amount.
