In this article, we will show you the main characteristics of SMD (Surface Mounted Device) LEDs and the various types of existing models, and we will provide you with a series of helpful application suggestions to make the most of the different models that exist today. This guide will not limit itself to providing information relating to the most commercial and widespread models of SMD chips but also takes into consideration unique models of SMD Screen sources which we present to the public here and which constitute an innovation capable of creating new lighting effects and solving problems until now difficult or impossible to resolve.
SMD LED: CHARACTERISTICS AND USES
SMD-type LEDs are light sources that have the characteristic of being installed in circuits mounted directly on an electronic board. These circuits are perforated to allow the passage of the electrodes, the soldering of which is carried out on the lower face of the base. These are components in which the electrodes do not protrude downwards but come out of the sides of the chip. They are characterized by their flat shape: the lower part is soldered directly onto the electronic board, while the electrical connections are lateral. In this way, it is possible to use printed circuits on an insulating base of reduced thickness and carry out micro-welding with automated machinery. This type of LED looks like a tiny box with one face from which the light is emitted, the opposite face acting as a support base, while the remaining lateral faces are equipped with an anode and cathode. In the past, they have been used in miniature circuits, such as those of cell phones, thanks to increasingly higher luminous efficiency. Today, they are widely used to create LED luminaires for general lighting. This kind of LED usually has a light output of 120 degrees and is typically used, for example, in producing LED strips.
This is essentially a fascinating family of LEDs since today it finds a great application both in the creation of LED strips and in the design of LED luminaires, especially where high efficiency and the achievement of very high lumens together with control of the exact light distribution (LED luminaires for public, industrial, cultivation lighting, etc.).SMDs are also a family of LED sources that allow the achievement of high standards of reliability and durability thanks to the possibility of fragmenting the power of the luminaire into a plurality of diodes to be powered with voltage generally in the order of milliampere (mA) (for For an in-depth look at the thermal management of SMD LEDs about COB LEDs, we invite you to read this dedicated article).
SMD LED: CHARACTERISTICS OF THE DIFFERENT TYPES
The recalled SMD LED source models all have peculiar characteristics that justify their existence. As is intuitive from reading the table, each model's name corresponds to the chip's dimensions expressed in millimetres. Here, we will delve into the most popular models and the most high-performance and professional ones that can be effectively used in general lighting.
3528 AND 2835 SMD LEDS
3528 SMD LED
3528 SMD LED
The SMD 3528 diodes represent the older models and are characterized by a light output that could be higher. The 3528 diodes are, therefore, primarily used in decorative lighting and are characterized by their low cost. On DOMAGIC, you will find the 3528 4.8W/m and 9.6W/m strips.
2835 SMD LED
2835 SMD LED
SMD 2835 diodes, on the other hand, are more recent and have enjoyed excellent diffusion on the market thanks to their greater efficiency and the possibility of creating LED strips with a good density of diodes. Precisely, this last aspect is fundamental when you want to create a luminous effect of continuous light and avoid the unsightly "dots" or "dotted" product, which is inevitable where SMD diode models characterized by a density of diodes per meter of less than 120 are preferred. LEDs. On DOMAGIC, we have various models of SMD 2835 diodes with multiple powers: 14.4W/m (120 LED/m), 17.3W/m (168 LED/m), 20.2W/m (240 LED/m) with high colour rendering (CRI>95)up to the brand new and very bright 25W/M (120 LED/m) LED Strips of 170lm/W and 4250lm/m with efficiency levels at the top of the market.
