What is SMD LED? What are the benefits?

What Is SMD LED? 

SMD LED stands for surface mount LED. Specifically, it's a light-emitting diode that is mounted onto and soldered onto a circuit board. An SMD LED is quite small since it has no leads or surrounding packaging that comes with a standard LED. This means it's best handled, not by a human, but by automated assembly equipment. An SMD LED also has a wide viewing angle, thanks to the fact that it does not have the standard LED's epoxy enclosure that focuses the beam. 

Benefits of SMD LED 

The SMD LED gives off very little heat. It also has a low voltage and current requirements. Like a standard light emitting diode, a surface mount LED gives off almost no heat. It also typically has similar low voltage and low current requirements. They are commonly used to indicate device status on computer motherboards, routers, hard drives, USB flash drives and any other application where physical space is at a premium. Computer motherboards, hard drives, routers, flash drives and other applications where there's no room for larger technology are also common uses. 

Others include LCD display backlighting, keyboard lights, and pushbuttons. They've also been used for instrument panels in aircrafts. A few manufacturers have created an SMD LED lighting solution by combining it with a resistor, small circuit board, lens and cable to provide and bright, cool LED light that runs on just 12 volts, and which is tiny enough to be mounted almost anywhere, (for instance, to light a cup holder). 

There are other, large-scale applications, too. For instance, they are used for indoor display screens. SMD LEDs work well because you can arrange a large number of diodes in tight groups of red, blue and green, generating a large variety of colors. This screen technology, which is now found in stores and malls, is now also popping up in large outdoor displays.

SMD LED gives high brightness while it has lower power consumption than of a normal LED light tubes (e.g. dip or cluster led) and traditional light bulbs.  See its features below:

FEATURES

Small Size: SMD LED light source is a very small and light chips enveloped by epoxy resin.

Low Power Consumption: Generally, the voltage per SMD LED is 2-3.6V, current 0.02A-0.03A. It uses very low voltage and current. Power consumption is very low, just equals to 1/8 of incandescent light, 1/4 of traditional light.

Long Life Span: Under proper current and voltage condition, the life span of SMD LED can reach 100,000 hrs.  Compared with the other LED tubes(like Dip LED),the optical decay reduce from 10% to 5% in 1000hrs. Produced by Automatic equipment, via heat emitting technical process, the life span of SMD LED is longer.

High Brightness: Mainly adopted 3528 and 5050 SMD high brightness chip, single SMD LED over 5.5lm/1800MCD.

As above, we have mentioned about SMD 3528 and 5050.  What do they mean and what is the difference between the two?  Let's see the following:

 SMD 3528

  • consists of one light-emitting chip

  • dimension of chip : 35 x 28 mm

  • power: 0.08W/ pearl

SMD 5050

  • consists of three light-emitting chips

  • dimension of chip : 50 x 50 mm

  • power: 0.24W/pearl

SMD 5630

  • consists of one light-emitting chips

  • dimension of chip : 56 x 30 mm

  • power:

Theoretically, SMD5050 is 3 times brighter than SMD3528.But even for the 5050 SMD, there are still many different versions. But there are three are widely used in the lighting industry. 1st:12-14 Lumen each SMD 2nd: 16 -18 lumen each SMD and the 3rd one which is the brightest in the normal applications: 22-24 Lumen each SMD. In LightingXY, our bulbs are normally installed the brightest 5050 chip and for the strips or LED tape, we normally use the 12-14 Lumen SMD unless we have the super bright products. SMD 5630 is high brighter than both 5050 and 3528.
