SMD represents Surface Mounted Device and COB mean Chip On Board. Light emitting diode or LED for brief has become extremely popular. The Surface Mounted Device (SMD) was initial presented in 2008. Whereas, the COB LED technology has been available since 2010 in Guangzhou at the Canton Fair.
These SMD chips are of various colors such as Blue, Green and Red which helps create colored lights. The COB LED lights are either ceramic or aluminum.
What is an SMD LED Light?
SMD lights utilize SMT innovation which installs the LED chip onto a PCB board. The PCB is integrated in a flat object, rectangular-shaped, and is what one sees as an SMD. One can see a small black point at the middle of the SMD if you look closely in an SMD LED, it is the LED chip. The back side of it has two steel points (cathode and anode) which are utilized for soldering with the circuit for the light.
The 5050 SMD has 3 steel points as there are 3 chips inside. The SMD Led has various kinds, such as 5730, 5630, 5050, 3030, 3014 and also 2835. Each of these is called as per the dimensions of the LED meaning it is based on the width and also length. Prior to the COB was created, the SMD 5050 and 3528 chip was utilized.
What is a COB LED?
The COB LED uses the new encapsulation innovation. As contrasted to the SMD 5050: 3 chips or the 3528: 1 chip, the COB LED has numerous chips on the same printed circuit board (PCB). The PCB is on the substrate of the COB. The diode chips of the COB are arrayed in series/ or parallel which depends upon the circuit. This substrate can either be ceramic or light weight aluminum. If you are seeking a much better thermal conductive efficiency, then ceramic type is what you need as it will certainly ensure a much reduced LED working temperature.
The COB LED has 2 metal connection points, the cathode and also anode. The COB has a much better thermal conductivity as compared to the SMD, as a result of the fact that it places chips directly to the substrate that has a huge cooling area. In order to have the COB size to be as small as possible, the circuit needs to be created to reduce the chip’s distance.
Final thought
COB LEDs are available in various forms which make it easier for them to be made use of for various fittings. Whereas, SMD lights can just be made use of for minimal fittings, there are several advantages of utilizing COB LED lights such as much better thermal conductivity as well as reduced manufacturing failing ratio as a result of the unique design.
Deciding between SMD and COB LED lighting depends upon your demands. Both of the lights are being used for different applications. When selecting in between the two lights, first find out about which fixture is being used for. LED lights have changed the entire lights market.
