SMD LEDs are currently the most used type of LEDs on the market. Due to the mass production of factories, prices have dropped substantially, plus the continuous innovations of semiconductor development, in which the SMD LEDs featured high endurance and low power consumption, and widely used in LED lightings, light bars, vehicles and personal electronic devices, etc.
Currently the most common type on the market, the core of it is semiconductor chip. The chip is connected to the bracket with positive on one end and negative on the other, and the whole chip is encapsulated with epoxy. It has replaced the old technology of using lead wire during assembly. With this technology more electronic devices can be installed in a small space more efficiently, it also supports the automated assembly of PCBs and the application of welding.
COB LED is a new light-emitting component technology, which is a high efficient integrated surface light source technology with more advantages compares to traditional LEDs. There is no need for electroplating and reflow soldering, therefore, it takes up very little space after packaging, and the close arrangement and combination may maximize the luminous efficiency, which makes COB light sources to look more like a whole piece of emitting panel.
The performance and energy efficiency of LEDs are better than other light sources with absolutely no doubts. Oasistek provides a variety of products with different specifications, the given links in this article may help you quickly find the product you are looking for.
