SMD LEDs and SMD LED chips: what they are and what they mean
SMD LEDs stand for Surface Mount Device and Light Emitting Diode. The combination of these acronyms indicates electronic components made up of LED modules that are mounted directly on one side of the printed circuit board using surface mount technology, known as SMT.
SMD LEDs are characterised by a parallelepiped shape, called a chip, which contains the emitting surface inside. The diodes that power the device are located on the sides.
Soldering SMD LEDs: how to do it?
SMD LED chips are self-contained LED devices that are mounted on the surface of the printed circuit board (PCB) by soldering, using SMT technology. This practice allows the SMD LEDs to be soldered onto both sides of the circuit board, without cutting or drilling into the board.
The advantages of using this type of component assembly are:
Types of SMD LEDs: all those you need to know
There are different types of SMD LEDs, and each variant is identified by a series of numbers that define its size and associated brightness level. The LED identification number corresponds to the size of the chip itself, expressed in millimetres.
As for the main types of SMD LEDs, the most common on the market are the . This was one of the first LEDs to appear on the market and is characterised by a power of between 6 and 8 lumens, a consumption of 0.20W and a very low light output.
The SMD LEDs provide an output of between 16 and 22 lumens. They are among the first chips to generate higher power and are therefore suitable for general lighting needs.
The recently developed SMD and LEDs provide good brightness at low power consumption and are therefore very popular. These SMD LEDs are suitable for use where high lumens are required.
Finally, SMD and LEDs are identified as having the longest life and best performance, due to the presence of a heat sink inside them that prevents the source from overheating. This type is usually used on LED strips for both lighting and purely decorative purposes.
SMD LED dimension
SMD LED chips are characterised by a rectangular shape that varies in length and width depending on the model. Generally, however, regardless of size, SMD LEDs do not exceed 5.7 millimetres in length and 5 millimetres in width.
The size of the SMD LED is what has the greatest influence on the brightness and power consumption of the device. The larger the device, the higher the brightness level. These characteristics are easy to understand thanks to the numerical abbreviation that identifies the different types of LED.
COB o SMD LEDs - what are the differences?
The term LED is often found in association with other acronyms, as seen with SMD LEDs. The term COB LED refers to chip-on-board LED technology. This technology was introduced in and enabled the development of high-power diodes with a small light-emitting surface area.
Why should you choose COB or SMD LEDs? The introduction of COB LEDs has brought with it some significant advantages. First of all, the possibility of miniaturising the luminaires and the light sources inside them. COB technology facilitates the installation of individual plates in close proximity. This allows precise control of the distribution of the light beam thanks to the absence of space between one LED module and another. However, one application limitation of this technology is the power rating of the luminaire (possibly less than 50/70W) on which it is to be installed. SMD LEDs are to be preferred over COB technology precisely because they are more reliable and perform better in high power applications.
Micro LED SMD - what are they
Today's market demands ever smaller, yet more efficient LEDs. The search for even better-performing SMD LED chips has led to the development of devices capable of achieving truly brilliant lumen/Watt ratios, thus enabling the development of ever-smaller luminaires. This has led to the development of SMD micro-LEDs, highly efficient miniaturised technologies for small circuits.
One example is the micro-LED circuit developed by Luxelt. The Italian company, which specialises in the design and production of electronic and lighting systems, has developed cutting-edge technology that we have used in our new series of micro-LED spotlights.

SMD RGB LEDs - what they are
SMD RGB LED technology allows the colour of light to be changed by using three diodes: red, blue and green. In order to vary the colour of the light, these diodes are mixed according to precise intensities.
In backlighting projects, it is common to use an RGB SMD LED source to give the light profile an aesthetic and design component and at the same time a functional aspect. Each colour can be associated with a specific application status to communicate a precise function to the end-user.
SMD LEDs: the colours available
SMD RGB LEDs offer a wide variety of colours in different combinations: blue, red, yellow and many others. The RGBW LED also has a white SMD LED variant, which stands for Red Green Blue and White. In the case of white SMD LEDs, a different shade of white can be seen depending on the specific source. The colour temperature of white, which can be warm, cool or neutral, depends on a number of factors, including the bin colour of a specific LED manufacturer.
SMD LED diodes and polarity
SMD LED polarity identifies the specific polarity of each LED module. The SMD LED diodes must respect the polarity and the operating voltage in order for the device to work correctly.
LEDs are formed by the presence of two pins, anode (+) and cathode (-), which mark a different polarity. On some types of LED, symbols can be found on the housings that specify the polarity of the chip.

Lighting is one of the biggest developments in the modern world. It&#;s allowed us to extend the day, and remain productive well through the night. And not too long ago, it allowed us to have brightness with much less heat generated and energy consumed through the development of a high-density LED strip.
LEDs revolutionized modern lighting by producing little heat and bright light, as well as offering unbeatable customizability. As such, LEDs have become the most popular lighting option in the 20th century, they remain the leading lighting solution most homeowners and designers choose for their lighting projects.
Since the first LED was sold back in the s, LED has had the opportunity to upgrade its technology. One of such upgrades is the discovery and sale of surface-mounted diodes (SMDs), with most LEDs available today being SMDs.
Not only are SMDs brighter than traditional LEDs, but they&#;re also more energy-efficient and more affordable, hence most LED lights and strip lights sold today are SMDs.
Is the LED you&#;re using an SMD? Should you buy an SMD type of LED? Learn more about SMD and find out how it differs from traditional LED to help you decide which type of lighting best suits your needs and which one you should spend your money on.
What Does SMD Stand for in LED Lights?
As mentioned above, SMD stands for a surface-mounted device. SMDs refer to electronic components that are soldered onto a printed circuit board (PCB). It&#;s a type of technology that aims to save space&#;an incredibly important feature as modern devices continue to shrink in size.
When it comes to LED lights, SMD means Surface Mounted Diode. Unlike traditional LED diodes with their long leads, the diodes in SMD are in the form of chips and have little to no leads.
While the diodes used in typical LEDs are mounted onto the PCB via through-hole technology (THT), leads from the LED are inserted into drilled holes in the PCB, the LED chips used in SMDs are soldered flat against it.
As a result, more LED chips with lower power requirements can be clustered together, resulting in less space taken up, as well as increased energy efficiency, wider beam, and longer lifespan!
What is the Difference Between SMD and LED?
Light-emitting diode (LED) is a semiconductor device that converts electric current into light. The diode consists of two terminals or leads, a cation and an anion, which allow for electricity to flow from one to another in one direction.
As electricity flows from one lead to the other, the electric current is transformed into photons through electroluminescence, producing light without generating much heat.
Meanwhile, SMD or surface-mounted diode is a special type of LED that uses surface-mounted technology to save space. SMDs use LED chips instead of diodes with long leads. These chips are soldered onto the PCB. And because the LED chips are made of semiconductive layers, electricity can flow freely instead of unidirectionally to produce light.
The lack of long leads allows LED chips to save space. By using LED chips instead of diodes, LED chips can be clustered together. As LED chips are clustered together, brighter light output can be achieved despite using lower power LED chips.
Traditional LEDs
While traditional LEDs use three to four high-powered LED chips with 25 to 40-degree beam angles to create one light, SMDs are powered by five or smaller LED chips with 20-degree beam angles per chip clustered together.
The proximity between LED chips allows their individual light output to combine, resulting in brighter lighting overall. The result is brighter lighting with lower power consumption from SMDs. Though each LED chip used in SMD LEDs have lower beam angles and consume less power, their strategic position allows them to have brighter as well as wider beam of lighting.
And because each LED chip consumes lower power, they tend to last longer than typical LEDs, making them energy efficient, as well as a durable choice, of lighting!
For these reasons, most high-density LED strips make use of SMDs. With more low-power LED chips along the same strip, one can achieve brighter lighting while still keeping the overall cost relatively low.
Should I Get SMD or LED?
When shopping for an LED lamp or light strip, it&#;s important to consider how you&#;re going to use it, besides how much it costs and how much electricity it consumes.
Though SMD LEDs are an upgrade to your typical LED, providing brighter lighting and wider beam, consuming less energy, lasting longer, and costing less, they are not always the better choice.
The biggest difference in the use of SMDs and LEDs lies in the brightness they produce. LED on its own is already much brighter than incandescent lighting. However, the new technology used in SMDs allows them to shine even brighter.
Such may be helpful for store displays or outdoor night lights, where brightness is valued. But brighter is not always better. This is especially true for indoor spaces that require dim lighting or downlight. For these uses, it&#;s better to opt for typical LEDs with bigger gaps between each diode.
