Abstract
Disclosed is a light bar having improved weather resistance, aerodynamics, antenna performance, and platform versatility by accommodating user-selectable antenna modules.
Claims29
An antenna-equipped light bar, comprising:
- a light bar housing in which are mounted lighting devices communicatively coupled to electrical circuitry;
- a cover for the light bar housing, the cover including a domed region and a major surface region, the domed region defining an interior cavity for which at least a portion of the interior cavity is located above a plane defined by the major surface region;
- a shielding panel located in the light bar housing and electrically isolated from the electrical circuitry coupled to the lighting devices, the shielding panel positioned in the light bar housing to provide shielding of electromagnetic interference (EMI) associated with the electrical circuitry coupled to the lighting devices, in which the shielding panel is integrated into the cover;
- and
- an antenna mounted atop the shielding panel so as to be at least partly shielded from the EMI.

A system, comprising:
- an antenna-equipped light bar, including:
- a light bar housing in which are mounted lighting devices communicatively coupled to electrical circuitry;
- a shielding panel located in the light bar housing and electrically isolated from the electrical circuitry coupled to the lighting devices, the shielding panel positioned in the light bar housing to provide shielding of electromagnetic interference (EMI) associated with the electrical circuitry coupled to the lighting devices;
- and
- an antenna mounted atop the shielding panel so as to be at least partly shielded from the EMI;
- a human-machine interface (HMI);
- and
- an on-board unit for converting from first electrical signals into second electrical signals, the first electrical signals being generated by the HMI indicating that the lighting devices are on, and the second electrical signals being generated by the on-board unit for wireless broadcast using the antenna.

An antenna-equipped light bar, comprising:
- a light bar housing in which are mounted lighting devices communicatively coupled to electrical circuitry;
- a shielding panel located in the light bar housing and electrically isolated from the electrical circuitry coupled to the lighting devices, the shielding panel positioned in the light bar housing to provide shielding of electromagnetic interference (EMI) associated with the electrical circuitry coupled to the lighting devices, in which the shielding panel includes one or more lateral shielding panels and central ground plane on which the antenna is mounted;
- and
- an antenna mounted atop the shielding panel so as to be at least partly shielded from the EMI.
