LED SMD Technology

Scientists have been seeking higher LED products and technologies. LED SMD are light-emitting diodes in which the elements of the diodes are mounted directly onto the surface of printed circuit boards. A printed circuit board is a flat board used to electrically connect and support electronic components. LEDs are bulbs that fit into an electric circuit and are illuminated by the movement of electrons.
Depending on the size, we put them into different SMD types, So now we have the 3528 LED SMD , 5050 LED SMD, 2835 LED SMD, 3030 LED SMD.  5050 SMD have 3 pcs chips, so can make Red ,Green and Blue color to in one lLED SMD. 3pcs chips LED SMD Advantage of better brightness, longer life time. 3030 LED SMD as its high lumen and low price advantage. Now become popular and popular.

LED COB
COB stands for Chip on Board (COB) LED modules. Which is a new technology of LED packaging for LED light engine. Multi LED chips are packaged together as one lighting module.

LED COB Light source works
COB technology allows the LED modules to be clusters on the circuit boards. Chips are mounted directly on to the circuit board.  The LED is bonded directly on printed circuit boards (PCB).  A polymer layer is placed over the LED COB for protection.  Silicone is used as the polymer layer to protect the COB due to its low photo degradation.

LED COB Advantage
Compared to traditional lighting LED COB modules are super bright for the small space they occupy.LED COB is multi chips packaged, it can 10 times more increase lighting area, so it avoid uncomfortable glare by the maximum extent. It is designed with better temperature management, smaller LED module for greater lumen output and lower production costs.
