Abstract

Systems and methods of providing illumination may be provided in accordance with the invention. A lighting unit may be provided comprising a plurality of light sources, each light source of the plurality being at least partially surrounded by an optical element, and a support assembly configured to support the light source above a surface. The light sources may be radio frequency (RF) coupled electrodeless plasma sources, and the support assembly may be a high-mast support assembly. In some embodiments, the optical element directs light toward the surface. In some configurations, each light source of the plurality may have one or more independently controllable and/or adjustable lighting characteristics. A lighting unit may communicate with a controller, which may provide instructions for controlling the light sources. A lighting system may be provided with a host controlling a plurality of lighting units, which may be organized into networks, and/or zones. The networks, zones, lighting units, and/or light sources may be independently controllable and/or adjustable. In some embodiments, management software may provide functionality for monitoring, reporting, controlling and/or interacting with the lighting system.

Claims

1. A high-mast lighting system to provide illumination for a large transportation yard or area with increased safety and security comprising:

a plurality of lighting units each of which comprising;

a plurality of radio frequency (RF) coupled electrodeless plasma light sources, each light source of said plurality being at least partially surrounded by an optical element, wherein the light source is configured to be rotatable along an axis parallel to a selected axis of the light source while the light source is providing illumination;

a high-mast support assembly configured to position the plurality of RF coupled electrodeless plasma light sources above a surface at a height of 60 feet or greater; and

a communication unit capable of communicating as a host, gateway, and/or controller with the plurality of RF coupled electrodeless plasma light sources; and

wherein the plurality of the lighting units are organized into a defined set of illumination zones for the large transportation yard or area, and each lighting unit or each RF coupled electrodeless plasma light source is independently controllable and/or adjustable based at least in part on a signal from one or more transponders provided on a pre-determined movable transportation object or vessel, wherein the signal from the one or more transponders automatically communicates a desired brightness level for a selectable subset of the plurality of the lighting units or the plurality of RF coupled electrodeless plasma light sources dependent upon the size or selectable requirements of the pre-determined movable transportation object or vessel for safety and security within one or more illumination zones selected from the defined set of illumination zones for an immediate or surrounding area in proximity to the pre-determined movable transportation object or vessel, and wherein the signal from the one or more transponders is received by a receiver located remotely from the plurality of lighting units positioned atop their corresponding high-mast support assemblies and in communication with the plurality of lighting units over a communication network.

2. The high-mast lighting system of claim 1, further comprising a removable modular optical assembly accessible from a bottom surface of the lighting unit, wherein the optical assembly contains the light source, wherein the light source is configured to be rotatable through a restricted range that includes the light source pointing directly downward towards nadir.

3. The high-mast lighting system of claim 1, wherein one or more lighting characteristics of each light source is adjusted based on software-generated signals or instructions from a controller, hardware-generated signals or instructions from a controller, or a combination thereof.

4. The high-mast lighting system of claim 3, wherein the software-generated signals or instruction are based on scheduling.

5. The high-mast lighting system of claim 3, wherein the hardware-generated signals or instructions are based on a real-time sensor reading.

6. The high-mast lighting system of claim 1, further comprising a housing having a bird deterrent assembly.

7. The high-mast lighting system of claim 1, further comprising a thermal management system comprising a venturi or orifice plate capable of promoting fluid flow driven by convection.

8. The high-mast lighting system of claim 1, further comprising a housing;

and an electronic indicator or transducer on an external portion of the housing, the electronic indicator or transducer providing information about an operational status or identification of the lighting unit.

9. The high-mast lighting system of claim 1, further comprising an

integrated wireless controller having a mechanism that enables non-wireless control of the lighting unit, wherein the integrated wireless controller is configured to receive a remote signal to activate the integrated wireless controller and enter a state of wireless control.

10. The high-mast lighting system of claim 1, further comprising an integrated optical assembly configured to attenuate RF emissions from the plurality of light sources.

11. The high-mast lighting system of claim 1, further comprising a housing;

and a wireless controller antenna mechanically integrated within the surface of the housing, wherein one or more lighting characteristics of each light source is adjustable based on a distance between a transponder in communication with the lighting unit and each light source.

12. The high-mast lighting system of claim 1, further comprises a plurality of sensors including at least one of the following:

(1) a light sensor configured to collect sensor data relating to one or more characteristics or parameters relating to a light source, a lighting unit, the lighting system, environment, the lighting system, or any combination thereof, (2) the receiver comprising a radio frequency (RF) ID receiver in communication with the pre-determined movable transportation object or vessel, and (3) a motion sensor for detecting motion in proximity to the high-mast light system, wherein each sensor is associated with a pre-selected brightness level for the illumination zones.

13. The high-mast lighting system of claim 12, wherein the sensor data are relayed by an external controller disjoined from at least a portion of the plurality of lighting units.

14. The high-mast lighting system of claim 1, wherein an individual lighting unit is configured to compensate for an event in one or more neighboring lighting units, wherein the event includes one or more of:

light unit turned off, light unit malfunctioning, and light unit experiences lumen degradation.

15. The high-mast lighting system of claim 1, further comprising a reserve light source, wherein the reserve light source provides reserve lumen capacity to compensate for desired light output.

16. The high-mast lighting system of claim 1, further comprising an internal control system, wherein the internal control system is bridged with an external control system, wherein the external control system comprises a security system, supervisory control and data acquisition (SCAD) systems, or enterprise resource planning/enterprise resource management (ERP/ERM) system.

17. A method for providing illumination for a large transportation yard or area with increased safety and security comprising:

providing a plurality of lighting units each of which comprising;

a plurality of radio frequency (RF) coupled electrodeless plasma light sources, each light source of said plurality being at least partially surrounded by an optical element, wherein the light source is configured to be rotatable along an axis parallel to a selected axis of the light source while the light source is providing illumination;
