Pendant or accent light with thermal expansion accommodation heat sink

摘要

An underwater pendant or accent light in contact with a body of water is provided. The underwater pendant or accent light has a housing. The housing has an at least one water tight end fitting at a first end of the housing and an at least one lens at a second end of the housing. An electronics section is further provided. The electronics section including an at least one controller contained within the housing and coupled to a power source. An at least one LED is coupled to the electronics section. An at least one heat sink is coupled to the at least one LED and the electronics section, the heat sink thermally coupled to and mounting the at least one LED and thermally coupled to the electronics section such that heat is communicated through the at least one heat sink. The heat sink has an at least one thermal expansion slot to accommodate thermal expansion of the heat sink as it absorbs heat, wherein the heat sink is in thermal communication through a thermal path with the housing and transmits the absorbed heat through the housing and lens to the body of water. A method of using same is also provided.
