What is SMD LED?

The SMD LED is a very small and lightweigh chip enclosed in epoxy resin.

These provide extreme brightness while maintaining low energy consumption when compared to other type of bulbs (eg. incandescent).

Generaly the voltage needs per SMD LED is aprox 2 - 3.6V * , 0.02A-0.03A. It therefore has very low voltage and amperage needs.

Compared to incandescent bulbs, energy consumption is at 1/8th. In perfect conditions it's life expectancy might reach as many as 100,000 hrs.

Most popular SMDs, are product no.s 3528 and 5050.

SMD 3528 is a single light emiting package (chip), while SMD 5050 is inside a 3 light emiting package.

The 3528 is so called to describe the dimentions of the chip (35x28mm), while it's consumption is aproximately 12V * 0.08W / chip.

Contrary, SMD 5050 dimensions are 50x50mm, and its energy consumption is 12V * 0.24W / chip.

In theory the 5050 SMD is 3 times brighter than 3528.

 

* Note: while we say 12V, yet we described above that it is 2-3,6V per SMD.

Thus in an SMD LED tape we cannot power-up less than 3 SMDs (4x3smd=12V)

 

Benefits: 

  • Direct energy savings due to low consumption
  • Low heat emition
  • No need for maintenance due to very large life expectancy (therefore low running costs)
  • White light enhances the real colours of your products on display
