Chip On Board (COB) Light-Emitting Diode (LED)
COB LEDs are basically multiple LED chips (typically nine or more) bonded directly to a substrate by the manufacturer to form a single module. Since the individual LEDs used in a COB are chips and not traditionally packaged, the chips can be mounted such that they take up less space and the highest potential of the LED chips can be obtained. When the COB LED package is energized, it appears more like a lighting panel than multiple individual lights as would be the case when using several SMD (surface-mounted device) LEDs mounted closely together.

Being multi-chip packaged, the light emitting area of a COB LED can contain many times more light sources in the same area that standard LEDs could occupy resulting in a greatly increased lumen output per square inch.

Get the COB LEDmug. After multiple individuals were Cob-smacked by the Web of Cob, I had to hire a Cob Cutter to make much needed repairs.

Get the Cobbedmug. According to A Way With Words, a podcast on PBS, cobs has sometimes been used to define a small or hard object such as testicles. When using the exclamation it can also mean “give it a little extra juice”, or “give it a little more testicular fortitude”

As the timer was running low and the home team was down by 1 point, a fan yelled “pour the cobs on”.
As Jill approached climax, in order to get her partner to increase intensity she yelled, “pour the cobs on!”
Instead of his friend consoling him, jacks friend told him to “pour the cobs” on and get over his ex.
