SMD is the abbreviation of surface mount device, LED is the abbreviation of light emitting diode, so SMD LED is surface mount light emitting diode. SMD LED is a semiconductor device that converts electric current into light. SMD LED is the most widely used type of LED in the market today, it is characterized by low energy consumption and high brightness and is widely used in home and industrial lighting, such as LED screens, TVs, projectors, etc. Among the large full-color screen need to use RGB system SMD LED. commonly used smd led models are mainly: 3528 SMD lamp beads, 5050 SMD lamp beads, etc..
