ABSTRACT:
A pivoted head lighting device for illuminating exhibit and display panels, display objects and work surfaces with substantially uniform spot-free spread of light. The device includes an elongated metal shell structure having an upper corner transition section and a lower front opening bearing a glass lens, a high intensity electric lamp tube positioned centrally within the shell structure, an elongated concave metallic light reflector within the shell structure between the lamp tube and upper corner transition section thereof, and an elongated support arm pivotally interconnected to the shell structure. The upper transition section includes integral internally-projecting tube gripping lip sections of semicircular configuration for holding a terminal cross-tubular swivel member for adjustable rotation therein. The internal cross-tubular swivel member is interconnected to an end of the support arm. The external diameter of the swivel member and the internal diameter of the gripping lip sections are substantially equal whereby rotation of the swivel member within the gripping lip sections to position the pivoted head of the lighting device and the light illumination therefrom is only accomplished by overcoming the rotation friction resistance between the swivel member and the internally-projecting tube gripping lip sections of the upper transition section of the shell structure.
