SMD means Surface Mounted Device and COB represent Chip On Board. Light emitting diode or LED for brief has become highly preferred. The Surface Mounted Device (SMD) was first presented in 2008. Whereas, the COB LED technology 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 helps create colorful lights. The COB LED lights are either ceramic or light weight aluminum.
What is an SMD LED Light?
SMD lights utilize SMT technology which installs the LED chip onto a PCB board. The PCB board is built in a flat item, rectangular-shaped, and is what one said as an SMD. One can see a little black point 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 2 metal points (cathode as well as anode) which are used for soldering with the circuit for the light.
The 5050 SMD has three steel points as there are 3 chips built-in. The SMD Led has various types, namely 5730, 5630, 5050, 3030, 3014 and also 2835. Each of these is named as per the dimensions of the LED meaning it is based upon the width and length. Prior to the COB was created, the SMD 5050 and 3528 chip was made use of.
What is a COB LED?
The COB LED uses the new encapsulation technology. As contrasted to the SMD 5050: 3 chips or the 3528: 1 chip, the COB LED has several chips on the same printing circuit board (PCB). The PCB is on the substratum of the COB. The diode chips of the COB are arrayed in series/ or parallel which depends upon the circuit. This substratum can either be ceramic or aluminum. If you are seeking a better thermal conductive performance, then the ceramic type is what you require as it will certainly assure a much lower LED working temperature.
The COB LED has 2 steel connection points, the cathode and also anode. The COB has a far better thermal conductivity as compared to the SMD, due to the truth that it installs chips directly to the substrate that has a big heat radiation area. In order to have the COB dimension to be as little as possible, the circuit requires to be created to reduce the chip’s distance.
COB LEDs can be found in various shapes which make it much easier for them to be utilized for various fixtures. Whereas, SMD lights can just be used for minimal fittings, there are numerous advantages of utilizing COB LED lights such as far better thermal conductivity and also lower production failing ratio because of the unique design.
Making a decision between SMD and COB LED lamps depends on your requirements. Both of the lights are being utilized for different applications. When picking between the two, initially find out about which fitting is being made use of for. LED lights have changed the entire illumination market.
