The word LED, which is the acronym for Light Emitting Diode, is a passive optoelectronic component characterized by its versatility, taking on many forms and being integrated into many optical elements, from screens to light bulbs and even photographic flashes.

One of its best features is its low energy consumption, as well as its longer lifespan, its durability that perfectly withstands almost any type of vibration, in addition to low heat emission.

Surface mount technology, better known by its acronym SMD (Surface Mount Device) is the method of construction of electronic devices most currently used. It is used for both active and passive components, and is based on the assembly thereof SMC (Surface Mount Component English) on the surface of the printed circuit. In the case of SMD LED technology is the differently constructedon the plate makes SMD LED and have a physical difference.

The SMD LED is an LED module that uses a surface mount technology to place a diode on the surface of a printed circuit and encapsulated on a semi-rigid resin. Typically used for lighting all types, since its opening angle can be 360° and LEDs, being very small, they can be distributed throughout the bulb. Ideal for decoration lighting in homes or places of transit dondand they will not be on continuously. It is also often used in automotive interior lighting. Each LED SMD chip is identified by a 4-digit number. This code identifies the size of the LED chip, the first two digits indicate the height and width the next two, in millimeters. For example, the dimensions of a LED 5050SMD are 5.0 x 5.0 mm. There is an exception, 3528SMD LED chip is also knownon how 1210SMD, with dimensions 3.5 x 2.8 mm.

The SMD led (surface mounted device) refers to how the LEDs are mounted on a board. This type of LEDs have a resin encapsulation on their surface. It does not reach the same performance as a COB LED and is usually used in less demanding luminaires due to its low heat dissipation, the main problem in this type of LEDs.

Its light is unidirectional, creating an angle of illumination is 360º to difof a COB LED. By not having any type of filament this type of LED is very durable and resistant to shock.
They are the typical LEDs that we can find in a strip of LEDs for decoration, we can find according to your design, a single LED that will emit white light or according to your distribution you can find 3 LEDs that emit the different primary colors that in combination will show different .

Your performanceIt is usually 60 to 70 lumens per watt.

Within the SMD LEDS range we can find those that work at 220v and those that work at 12/24v.
Its nomenclature is of type SMD5050, SMD3528 and SMD3014 etc. where the figures indicate the size of the led, for example a led SMD5050 will have a size of 5x5.0mm
