Patent ID: 8905603

Claim:
A coupling for use with a lamp fitting operated by a power supply, which coupling allows safe mounting/dismounting of the fitting without electrical isolation from the supply, said coupling comprising: a mounting member having a first electrical connector element with shielded contact points connectable to the power supply, said member being suitable for fixing to a structure, wherein the first electrical connector is disposed within a housing of the mounting member to at least partially isolate the first electrical connector within the housing of the mounting member; and a holder member engageable with the mounting member and comprising a cylindrical element adapted to receive at least a portion of the mounting member and able to support a standard or industrial commercial lamp fitting having a lamp, said holder member having a second electrical connector element able to conduct power to a lamp fitting, wherein the second electrical connector is disposed within a housing of the holder member to at least partially isolate the second electrical connector within the housing of the holder member; wherein engagement of the mounting member and the holder member allows the first and second electrical connector elements to come into contact and disengagement allows electrical contact to be broken without substantial exposure of the contact points; wherein, when engaged, the mounting member and the holder member form a water-resistant housing and the housing has a longitudinal axis, and wherein the mounting member and the holder member are engageable through a full 360 degrees of rotation about the longitudinal axis.
