SMD LED modules have become popular in the manufacturing of LED fixtures and LED strips for lighting in various capacities in several fields. This technology is applied where the lighting utilization factor is high and strict control of light density is needed.
SMD LEDs are comparatively more durable, with less power consumption and higher reliability and safety standards. But for those who have never heard of or seem to know what an SMD Screen is all about, perhaps the following explanations can be of some assistance.

SMD LEDs and SMD LED Chips: what they are and their meaning
SMD LEDs stand for light-emitting diode and surface mount devices, which are English abbreviations. These acronyms make people understand that these are electronic components created from LED modules that are soldered directly on one side of the printed circuit through the surface mount technology commonly referred to as SMT.
The SMD LEDs are distinguished by a parallelepiped block called a chip, where the emitting surface is located. On the sides, however, are the diodes that enable them to be powered by a specific supply voltage.
Soldering SMD LEDs: How do you do it?
SMD LED chips are discrete LED packages or dies that form the required LED elements soldered to the printed circuit board or PCB using Surface Mounting Technology. This practice allows you to solder the SMD LED on both sides of the circuit board without engraving or drilling it on the board.
- The advantages deriving from the use of this type of component assembly are:
- the possibility of using smaller components and creating more compact electronic boards ;
- the reduction of the production of waste resulting from the circuit drilling operation;
A consequent reduction in work times, as a series of automated machinery is used, including the Pick Place machine.

Types of SMD LEDs: the most that you might want to know
SMD LEDs come in various classes, each distinguished by numbers indicating size and brightness. The LED identification number relates to the dimension of the chip itself, measured in millimeters.
Considering the main types of SMD LEDs, the most popular one to purchase at the moment is the 3528. It is the first LED to be produced in the market and is marked by its power of between 6 and 8 lumens, consuming 0: 20W, just slightly less light output than the Raxa Vision DL650.
The 5050 SMD LEDs ensure a power rating ranging from 16 to 22 luminous intensity. They are among the initial chips that can produce more power output and, as such, serve for general-use lighting.
The 5630 and 5730 SMD LEDs are relatively new. They ensure good illumination with little to no energy, and for this reason, they are very popular today. These are SMD LED diodes ideal for use when higher lumen output standards are to be attained.
Finally, the 2835 and 3014 outdoor SMD screens are identified as the devices with the most extended life and best performance, thanks to the heat sink inside them, which prevents the source from overheating. This type is usually used on LED strips with lighting and purely decorative functions.
