SMD stands for Surface Mounted Device and COB mean Chip On Board. Light emitting diode or LED for brief has actually come to be highly preferred. The Surface Mounted Device (SMD) was initial presented in 2008. Whereas, the COB LED technology has been readily available from 2010 in Guangzhou at the Canton Fair.
These SMD chips are of various shades such as Blue, Green as well as Red which assists produce colored lights. The COB LED lights are either ceramic or light weight aluminum.
What is an SMD LED Light?
SMD lights use SMT innovation which places the LED chip onto a PCB. The PCB board is integrated in a flat item, rectangular-shaped, and is what one sees as an SMD. One can see a small black spot at the center of the SMD if you look closely in an SMD LED, it is the LED chip. The rear side of it has two metal spots (cathode as well as anode) which are used 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 different types, such as 5730, 5630, 5050, 3030, 3014 and also 2835. Each of these is named based on the measurements of the LED indicating it is based upon the width as well as length. Before the COB was created, the SMD 5050 as well as 3528 chip was made use of.
What is a COB LED?
The COB LED utilizes the new encapsulation technology. As contrasted to the SMD 5050: 3 chips or the 3528: 1 chip, the COB LED has multiple chips on the same printing circuit board (PCB). The PCB gets 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 aluminum. If you are searching for a better thermal conductive performance, then ceramic kind is what you need as it will certainly guarantee a much reduced LED running temperature.
The COB LED has two metal connection spots, the cathode as well as anode. The COB has a far better thermal conductivity as contrasted to the SMD, due to the fact that it installs chips directly to the substratum that has a huge heat radiation area. In order to have the COB dimension to be as small as possible, the circuit needs to be made to shorten the chip’s distance.
COB LEDs can be found in various shapes that make it easier for them to be made use of for different fittings. Whereas, SMD lights can only be made use of for limited fittings, there are lots of benefits of utilizing COB LED lights such as better thermal conductivity as well as lower production failing ratio due to the patent design.
Determining between SMD and COB LED lighting relies on your requirements. Both of the lights are being utilized for various applications. When picking between the two lights, initially understand about which fitting is being made use of for. LED lights have changed the whole lights market.
