SMD stands for Surface Mounted Device and COB represent Chip On Board. Light emitting diode or LED for brief has actually come to be highly preferred. The Surface Mounted Device (SMD) was first presented in 2008. Whereas, the COB LED innovation has actually been available from 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 light weight aluminum.
What is an SMD LED Light?
SMD lights make use of SMT innovation which mounts the LED chip onto a PCB board. The PCB is integrated in a flat item, rectangular-shaped, and is what one said as an SMD. One can see a tiny black spot at the center 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 three metal spots as there are three chips built-in. The SMD Led has numerous kinds, such as 5730, 5630, 5050, 3030, 3014 as well as 2835. Each of these is called based on the measurements of the LED meaning it is based upon the width and length. Prior to the COB was created, the SMD 5050 as well as 3528 chip was used.
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 several chips on exact same printed circuit board (PCB). The PCB is on the substrate of the COB. The diode chips of the COB are organized in series/ or parallel which depends on the circuit. This substratum can either be ceramic or light weight aluminum. If you are looking for a better thermal conductive performance, then the ceramic kind is what you need as it will certainly guarantee a much lower LED working temperature.
The COB LED has two metal link points, the cathode and also anode. The COB has a far better thermal conductivity as contrasted to the SMD, because of the truth that it installs chips straight to the substrate that has a substantial heat radiation space. In order to have the COB dimension to be as small as possible, the circuit requires to be designed to reduce the chip’s distance.
COB LEDs are available in various forms which make it simpler for them to be utilized for various fittings. Whereas, SMD lights can only be made use of for restricted fittings, there are many benefits of using COB LED lights such as far better thermal conductivity and also lower manufacturing failing ratio due to the special design.
Determining between SMD and COB LED lights depends on your requirements. Both of the lights are being made use of for different applications. When choosing between the two, first know about which fixture is being used for. LED lights have actually changed the whole lighting industry.
