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 Cobbingmug. This is someone who’s very very important to the people around them. Although they may not see it themself they are a good looking, amazing, caring, funny person who deserves the world. They’re the kind of person to help you even if they’re not doing great themself. You’re a lucky person if you get a Jac on a cob as a best mate. You should look after them and make them happy. Show them that they’re loved and cared for as sometimes they fail to see that for themself. Remind them not to let others bring them down because people who don’t treat them with respect aren’t worth changing themself over. Although usually they’re one of the best people to Go to for help or to cheer you up, sometimes they need cheering up too. Don’t become dependent on them as they might need help too. It’s ok to be sad, reassure them that you’re here for them. Overall jac on the cobs are honestly one of the best kind of people. You need to help them realise that. They’re never ugly. They’re never selfish. They’re never useless. They’re never unworthy of being loved and cared about. they’re amazing people.
