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 use of LED bulbs has grown exponentially due to its great advantages. The LEDs are diodes that when passing the current emit light, these LEDs are controlled with a driver or power supply, providing a very stable power source and thanks to its dissipation system can achieve high performance and many hours of illumination .

• Duration of up to 50,000 hours, thanks to its dissipation system and voltControlled air.
• Fast on. The LED lights up much faster than a conventional light bulb.
• They do not emit almost heat, so they do not burn when touched.
• They contain no gas, no mercury, no pollutants.
• They consume 80% less than traditional light bulbs. Thanks to its continuous research, it is possible that this type of technology continues to evolve and reduce its consumption.
• LWhich emit, do not radiate ultraviolet or infrared rays.
• Low maintenance, since the LEDs do not melt, it only decreases its power. This dramatically lowers maintenance costs.
• Different shades, we can find different types of LEDs where we will find different shades of light, which can go from 2700K (yellow light) to 8000K (white light) without using filters.
• Sturdiness,If we compare with conventional light bulbs we find that LED technology withstands the vibrations much better. Ideal for what type of extreme installations.
• Emitting a direct light, the LED is characterized by being a directional light, so there is no loss of light.

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 socket is the part that allows connecting the bulb to the socket. There is a wide selection of bushings for different types of bulbs. The nomenclature for each type includes 1 or more letters (type of lampholder), followed by 1 or more numbers (diameter of lampholder).
Example: The bush E27 would correspond to the type of thread E (Edison) of 27mm in diameter.

• E12: Diameter of 12mm, this is a tamYear smaller than the most commonly used standard E27.
• E14: It is the second most common cap, only varies a little of the E27, with a diameter of 14 to 17 mm. It is normally used for bulbs or lamps.
• E27: This is the most common cap. It has a thick cup shape with thread to be able to adapt to the connector. It measures 27mm wide.
• E40: Has a diameter of 40 mm, it is the largest thread of this tIpo.
• G4: With a distance between pins of 4.0 mm. It is a type of cap that is frequently used in appliqués, ceiling lamps and hanging lamps.
• G5.3: With a distance between pins of 5.33 mm. The GU 5.3 socket format is a format widely used in small led floodlights with transformer. Usually used in halogen lamps and dichroic halogens.
• GY6.35: With a distance between pins of 6.35 mm, trOf a model similar to the previous one.
• G9: With a ditancia between pins of 9,0 mm. Usually used for ceiling lamps and hanging lamps.
• G13: With a distance between pins of 12,7 mm. It is used in fluorescent tubes.
• GX53: With distance between pins of 53 mm. Its most common use is the installation in light bulbs to illuminate furniture or unusual places. It does not need transformer.
• GU10: With a distance between10 mm pins. The GU10 bushing shape is a widely used format in small transformerless LED spotlights. Usually used in dichroic halogen lamps.
• B22: Type of bayonet connector used in countries such as Africa, India and Ireland.
• MR16: Its use is normally limited to 12V halogen lamps.

VAC would be the abbreviation of Volt Altern Current which would be translated Volts of alternating current. The difference between VDC is that its sinusoidal oscillation achieving a more efficient energy transmission.

The alternating current is the energy that we receive in our homes, it is generated in the power plants by means of alternators.

The intensity of this type of current varies with time, and changes direction 50 times throughsecond (50hz). The generated voltage changes in the form of sine wave so it is not constant.

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
