A DC low voltage power distribution unit for a power grid and the corresponding DC low voltage power distribution system. A DC low voltage power distribution unit has at least one input connector for connecting the power distribution unit to a DC power supply, an electric distribution circuit comprising an input line connected to said input connector, and a reference potential line. The input line branches off into a plurality of output lines. The electric distribution circuit also has current limiting means in each of the output lines, wherein a current limit value is provided by the current limiting means to limit an output power at each of the output lines to an inherently safe value. A plurality of output connectors are connected to the output lines and to the reference potential line, wherein each of the output connectors are configured for outputting low DC voltage to a DC load.

DC low voltage power distribution unit and system for a power grid

A lighting fixture, such as for street lighting, comprises an external housing () which has a radio frequency antenna () integrally formed therewith. The RF antenna enables telemanagement signals to be passed to the lighting fixture, and for the telemanagement signals to be passed between lighting fixtures in a network. The RF antenna is ideally located in or on a translucent dome portion () of the lighting fixture which is invariably formed from a dielectric (non-conductive) material and therefore avoids undesirable RF shielding in at least preferred directions.
