LED Diode COB 3W White SMD

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 light output of up to 120 lumens / watt (twice as much as LED SMD)- the light intensity is greater without the need to concentrate the beam of light- greater durability- opening angle of 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.
