US Patent 7741782 Lighting fixtures incorporating Rf antennae

A lighting fixture, such as for street lighting, comprises an external housing (11) which has a radio frequency antenna (26, 26a, 27) 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 (14) 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.
