SMD stands for Surface Mounted Device and COB mean Chip On Board. Light emitting diode or LED for brief has actually become extremely preferred. The Surface Mounted Device (SMD) was first introduced in 2008. Whereas, the COB LED innovation has been available since 2010 in Guangzhou at the Canton Fair.
These SMD chips are of different colors such as Blue, Green and Red which assists produce colorful lights. The COB LED lights are either ceramic or aluminum.
What is an SMD LED Light?
SMD lights use SMT technology which mounts the LED chip onto a PCB board. The PCB is constructed 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 carefully in an SMD LED, it is the LED chip. The back side of it has two steel spots (cathode as well as anode) which are utilized for soldering with the circuit for the light.
The 5050 SMD has 3 steel spots as there are 3 chips built-in. The SMD Led has various types, such as 5730, 5630, 5050, 3030, 3014 as well as 2835. Each of these is called according to the measurements of the LED implying 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 makes use of the brand-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 printed circuit board (PCB). The PCB gets on the substrate of the COB. The diode chips of the COB are ranged in series/ or parallel which depends on the circuit. This substrate can either be ceramic or light weight aluminum. If you are seeking a much better thermal conductive performance, then ceramic kind is what you require as it will assure a much lower LED working temperature.
The COB LED has two steel link spots, the cathode and anode. The COB has a far better thermal conductivity as contrasted to the SMD, as a result of the fact that it places chips straight to the substrate that has a substantial cooling space. In order to have the COB dimension to be as little as possible, the circuit requires to be developed to reduce the chip’s distance.
Verdict
COB LEDs can be found in different forms which make it simpler for them to be utilized for various fixtures. Whereas, SMD lights can just be utilized for restricted fittings, there are several advantages of making use of COB LED lights such as far better thermal conductivity as well as reduced manufacturing failing ratio as a result of the special layout.
Choosing between SMD and COB LED lighting relies on your needs. Both of the lights are being utilized for different applications. When choosing in between the two, first find out about which fixture is being used for. LED lights have actually changed the entire lighting market.
