Abstract
A light fixture for a security lighting system includes an elongated pipe having a lower pipe section, an upper pipe section, and an articulating joint coupling a lower end of the upper pipe section with an upper end of the lower pipe section for enabling the upper and lower pipe sections to articulate relative to one another. A clamping element is coupled with the lower end of the lower pipe section. A glare shroud is secured to the upper end of the upper pipe section. One or more LEDs are secured to an underside of the glare shroud. Each LED has an optical lens that is configured to pass light from the underside of the glare shroud at a predetermined beam angle of 137-156 degrees.
Claims20
A light fixture for a security lighting system comprising:
- an elongated pipe including a lower pipe section and an upper pipe section;
- an articulating joint coupling a lower end of said upper pipe section with an upper end of said lower pipe section for enabling said upper and lower pipe sections to articulate relative to one another;
- a clamping element coupled with the lower end of said lower pipe section;
- a glare shroud secured to the upper end of said upper pipe section;
- one or more LEDs secured to an underside of said glare shroud, wherein each said LED has an optical lens that is configured to pass light from said underside of said glare shroud at a predetermined beam angle;
- wherein said light fixture is mounted onto a vertical post of a perimeter fence having a fence line, and wherein a distance from the fence line where a glare zone begins is selected by knowing the predetermined beam angle of the light that is passed from said underside of said glare shroud, adjusting the height off grade of the upper end of said light fixture, and tilting said upper pipe section relative to said lower pipe section.
A security lighting system comprising:
- a perimeter fence having vertical posts spaced from one another along a fence line;
- security lighting fixtures mounted on at least some of said spaced vertical posts;
- conductive wiring interconnecting said security lighting fixtures;
- a power source coupled with said conductive wiring, wherein said power source produces extra low voltage that does not exceed 50 volts;
- each said security lighting fixture comprising
- an elongated pipe including a lower pipe section and an upper pipe section,
- an articulating joint coupling a lower end of said upper pipe section with an upper end of said lower pipe section for enabling said upper and lower pipe sections to articulate relative to one another,
- a glare shroud secured to the upper end of said upper pipe section;
- one or more LEDs secured to an underside of said glare shroud for projecting light toward a top of said perimeter fence and along said fence line.
A security lighting system comprising:
- a perimeter fence having vertical posts spaced from one another along a fence line and wire mesh interconnecting said vertical posts;
- security lighting fixtures mounted on said spaced vertical posts, wherein said security lights are spaced from one another and have upper ends positioned above a top of said perimeter fence;
- conductive wiring interconnecting said security lighting fixtures;
- each said security lighting fixture comprising
- an elongated pipe including a lower pipe section and an upper pipe section,
- an articulating joint coupling a lower end of said upper pipe section with an upper end of said lower pipe section for enabling said upper and lower pipe sections to articulate relative to one another,
- a clamping element for securing said security lighting fixture to one of said vertical posts,
- a glare shroud secured to the upper end of said upper pipe section and defining the upper end of said security lighting fixture;
- and
- one or more LEDs secured to an underside of said glare shroud.
