What Is A COB LED ? What Does COB Mean ? Should I Make The Switch ?

COB ( chip on board ) LED products are slowly starting to seep into the market , it is set to take the whole industry by storm soon. A chip on board LED is basically a LED chip diode built directly on the the circuit board. The chips are bonded directly into the PCB at the manufacturer. Without traditional LED packaging ( 5mm LED , 3528 , 5050 , 5630 , 5730 SMD LED ) , components and assembly is avoided to max out the full potential of the LED chip. 


What does this all mean ?

Due to less components in the LED chip , the thermal conductivity is directed at the circuit board and without traditional LED chip packaging structure, research shows that an average of 25% less heat is emitted from the LED chip. Less heat means much higher efficiency rate and lower failure rates.

Spot soldering is no longer necessary as the chip is built directly on to the circuit board, less welding points means less chances of failure. PC lenses and other traditional LED packaging parts are also no longer needed, therefore light visibility range is increased and light loss from lenses are decreased substantially. All these factors are important to ensure a long lasting LED chip.

COB LEDs are an integrated package. With less spacing between the LED chips , a much wider surface can be covered by the COB LED's light beam with less glare. CRI is increased due to the wider beam angle.


Should I make the switch ?

Still a new technology , we would wait around 1-2 years for more matured COB LED products to come out in the market. But it wont hurt for you to start looking into products that utilize COB LED technology

    How big of a cob light would it take to replace a 300 watt bulb.
