Low voltage light fixtures having articulating components for establishing blinding glare zones at selected distances from the fence lines of security fences

A security lighting system comprising:

• a perimeter fence having vertical posts spaced from one another along a fence line, said vertical posts having a height of 8-12 feet off grade;
• security lighting fixtures mounted on at least some of said spaced vertical posts, wherein said security lights are spaced from one another and have upper ends defining a height of 9.5-13.5 feet off grade;
• conductive wiring interconnecting said security lighting fixtures;
• a transformer coupled with said conductive wiring, wherein said transformer 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 rigid upper pipe section;
• one or more LEDs secured to an underside of said glare shroud, wherein each said LED is adapted to generate light having a beam angle of 137-156 degrees.

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, wherein said vertical posts have a height of 8-12 feet off grade;
• security lighting fixtures mounted on said spaced vertical posts, wherein said security lights are spaced 10-30 feet from one another and have upper ends positioned at a height of 9.5-13.5 feet off grade;
• conductive wiring interconnecting said security lighting fixtures;
• a transformer coupled with said conductive wiring, wherein said transformer produces extra low voltage that does not exceed 50 volts, and wherein said security lighting fixtures operate on 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 clamping element for securing said security lighting fixture to one of said vertical posts,
• a glare shroud secured to the upper end of said rigid upper pipe section and defining the upper end of said security lighting fixture;
• one or more LEDs secured to an underside of said glare shroud, wherein each said LED is adapted to generate light having a beam angle of 137-156 degrees.
