SMD means Surface Mounted Device and COB represent Chip On Board. Light emitting diode or LED for brief has come to be extremely preferred. The Surface Mounted Device (SMD) was first presented in 2008. Whereas, the COB LED technology has been available from 2010 in Guangzhou at the Canton Fair.
These SMD chips are of various shades such as Blue, Green and Red which assists create colorful lights. The COB LED lights are either ceramic or aluminum.
What is an SMD LED Light?
SMD lights use SMT technology which places the LED chip onto a PCB. The PCB board is constructed in a flat item, rectangular-shaped, and is what one said as an SMD. One can see a tiny black spot at the middle of the SMD if you look carefully in an SMD LED, it is the LED chip. The rear side of it has two steel points (cathode as well as anode) which are made use of for soldering with the circuit for the light.
The 5050 SMD has three steel points as there are 3 chips inside. The SMD Led has different kinds, namely 5730, 5630, 5050, 3030, 3014 as well as 2835. Each of these is named according to the dimensions of the LED implying it is based upon the width and also length. Prior to the COB was invented, the SMD 5050 and 3528 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 numerous chips on exact same printing 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 relies on the circuit. This substrate can either be ceramic or aluminum. If you are looking for a better thermal conductive efficiency, then the ceramic type is what you require as it will assure a much reduced LED working temperature.
The COB LED has 2 steel link points, the cathode as well as anode. The COB has a much better thermal conductivity as contrasted to the SMD, because of the truth that it places chips directly to the substrate that has a big heat radiation area. In order to have the COB dimension to be as small as possible, the circuit requires to be made to shorten the chip’s distance.
Conclusion
COB LEDs can be found in different shapes which make it less complicated for them to be utilized for different fittings. Whereas, SMD lights can only be made use of for limited fittings, there are many benefits of utilizing COB LED lights such as much better thermal conductivity and lower manufacturing failing rates because of the patent design.
Choosing between SMD and COB LED lights relies on your demands. Both of the lights are being made use of for various applications. When selecting between the two lights, first know about which fixture is being utilized for. LED lights have changed the entire illumination industry.
