LED Types

We can summarize the general concepts which are encountered during classification of LED luminaries:

 

Single LED: Single LED is the first generation LED system used in lighting. They are defined as semi-conductor diod which is consisting of the LED chip which defines pure brightness and efficacy factor, the phosporus layer that defines light color & color balance and the package that covers LED chip and phosphorus layer while supporting the emission level of light and heat dissipation.  Then these LEDs are attached onto the printed circuit board (PCB) either by single or multiple way, according to layout of the electronic circuit. As a final product, these LED modules are used as light source.

 

COB LED: COB LEDs are module LEDs which are specifically designed for lighting and which are easy to mount and change. Multiple tiny LEDs operating together in a central point at COB LEDs allow the light to come out of a single source.

 

Linear LED: COB LEDs are module LEDs which are specifically designed for lighting and which are easy to mount and change. Multiple tiny LED chips that are covered by a phosphorus layer and  operating together in a central point at COB LEDs allow the light to come out of a single source like a lamp.

 

DC LED: They are the LED systems operating with the direct current. In these systems, a driver is used to stabilize the current with which the LED will operate.

 

AC LED: They are the LED systems operating by connecting to the electric network through a driver operating with an alternative current.

 

RGB LED:  They are the LEDs which can change color thanks to their special structure and driver. 16.7 million different colors may be obtained from a LED with RGB feature.
