COB LEDs are built as a matrix of LEDs, that is, a concentration of LEDs in a silicone coated tablet.
The advantages of LED COB:
- A luminous performance of up to 120 lumens / watt (twice as much as LED SMD)
- The light intensity is greater without needing to concentrate so much the beam of light
- Greater durability
- Angle of opening up to 160ºC
- Multidirectional light
Mount LED diode on a good heatsink, add some fan, this is necessary because you have to "remove" the heat from the surface of the plate so that the LEDs last longer to place a little bit of thermal silicone in each of the placement centers the diodes.
The thermal paste increases the thermal transfer between the diode and the metal plate used as a circuit.
