An underwater light fitting

摘要

The invention relates to an underwater wall mounted light fitting ( I ) comprising a sealed or scalable light source chamber (7) having a lens (3) and a scalable electrical supply connection chamber (22) including a port (35) to sealingly engage over an electrical supply line with a dividing wall (6) of insulating material provided between the two compartments and an array of electrical conductive connectors (24) embedded in the dividing wall (6) and each providing a connection terminal on opposite sides of the wall (6) within the chambers respectively. The dividing wall (6) is moulded around the connectors (24) which are provided as rigid spigots with circumferential grooves (31 ) to receive the moulded wall material. Grub-screws into cross passages are used to engage the electrical wire in each spigot. The connection chamber (22) is hollow cover (35) with the port (35) which includes a compression gland assembly (36) for an electrical supply line. The dividing wall (6) is securable against a peripheral frame (4) provided on the lens (3) and the frame (4) includes a continuous flange (5) extending away from the lens (3) which fits around the dividing wall (6). O-rings (15) between the components seal the two chambers (7, 22). The housing (2) is releasably securable to a wall mountable bracket (9). Surface mount-device (SMD) light emitting diodes (LEDs) ( 10) on a printed circuit board (1 1 ) provide the light source.
