Avago has released the "World’s first waterproof RGB PLCC-6 LED-family" with IPX6-rated surface mount LED packages.
The objective of this Application Note is to provide users a general understanding of the IPX6 coding, its advantages as well as precautions needed when using these LEDs.
IPX6-rated surface mount LED packages are capable of withstanding direct exposed to the outdoor environment where rainfall, condensation, mist or water splashes can come in direct contact with the LED surface. Moreover, sign and display makers can now design their products without a transparent plastic cover when using Avago’s LED with IPX6 rating. This directly reduces the material and assembly costs of the end product as well as eliminating the unwanted reflection from the plastic cover.
