COB LEDs, which stand for LED Chip On Board, are single LED chips joined together within a single module; generally within each COB chip, we can find from 9 or more diodes.
An important fact that characterizes this technology is the luminous efficiency which in this case is usually between 70 lumens per watt up to 100 lumens per watt.
Which are the advantages of COB LEDs?
COB LEDs are characterized by a single circuit with two contacts for the entire chip; the main consequence is, therefore, the simplicity of realization of the entire module. The reduction of necessary components, together with the elimination of the standard case also have a significant impact on the reduction of heat generated by the chip; this is, in fact, one of the main problems of this technology, overcome by the coupled with the right heat sink, able to transmit heat actively or passively and reducing the overall operating temperature of the entire group.
Digimax always recommends that you pay attention to choosing the right heat sink as this will allow you to take full advantage of the device chosen, drastically reducing the chances of malfunction and increasing the efficiency and operating life.
Where to use COB LED lighting?
The solutions are many: from the lighting of internal points of sale with the classic spotlights on the ceiling or suspended, to the public lighting of large areas such as road networks.
