Abstract:
1. A lighting fixture including an external lamp housing for confinement of a lamp and an electrical control system, the external lamp housing including: a first lower enclosure portion thereof formed from electrically non-conductive material, the first lower enclosure portion forming a suitable substrate for a radio frequency antenna which is integrally formed therewith preferably in the form of an electrically conductive pattern or wire disposed on or in a sidewall of the first lower enclosure portion, the radio frequency antenna including a plurality of electrically conductive elements of appropriate length to correspond to an appropriate operational frequency of an RF driver circuit, wherein each element is spaced at appropriate fractions of the operational wavelength for maximum transmission efficiency; and wherein the first lower enclosure portion is formed from a translucent material through which optical output of the lighting fixture is directed such that the lower enclosure portion presents a line of sight to the lamp in at least two opposing directions substantially along a horizontal plane passing through or adjacent to the lamp, and a second substantially opaque portion confining the electrical control system of the lighting fixture.
