Abstract: A LED lighting device enables the assembly of one or more LED products in a variety of structures for a broad range of applications. In particular, one or more prefabricated individual water-resistant LED products are assembled in an attachable/detachable fixing frame in a variety of structures for use in a broad range of applications which include street lights, security lighting, tunnel lights, floodlights, etc. A further advantage of a LED lighting device is that it can be conveniently used with AC power, without the use of an AC/DC adapter or a stabilizer.
