SMD LED Modules&Applications

SMD LED Modules are described by the dimensions of the LED package, an identification system that is a hold over from the time when only monochrome SMD LEDs existed. Monochrome SMD LED modules are good for accent lighting, task lighting and the like and generally come in a bright white or warm white variants. However, the advent of multicolor SMD LEDs has made this system of module identification by its package size a bit confusing. It thus requires the end user to have more familiarity with the technology than is normally expected. For example, an SMD 5050 LED module is a very popular type on online shopping sites for use in flexible LED strips. Armed with only the understanding that the individual LED modules used on a "5050 strip" have package dimensions of 5.0mm x 5.0mm does not clue the buyer into the fact that most 5050s sold have 3 individual LEDs within that package, one each of red, green and blue. Paired with the proper LED controller, these SMD LED packages can form many colors by varying the brightness of the three individual LEDs enclosed within them.

Common types of SMD LED modules are 0603 SMD LED Module, 1206 SMD LED Module, 3020 SMD LED Module, 5630 SMD LED Module and the SMD 5730 LED Module.[2] The brightness may vary depending on the driving current, inversely affecting the device's lifespan.


SMD LED modules are widely used, in LED lamps, for backlighting, home illumination, shop-windows, advertising, automobile interior lighting, Christmas lights, and numerous lighting applications.
