subject: Wall Washer Light With Internal Swivel Connector And Support Arm [print this page] A pivoted head lighting device for illuminating exhibit and display panels, display objects and work surfaces with substantially uniform spot-free spread of wall washer 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.
In a pivoted head lighting device for illuminating exhibit and display panels, display objects and work surfaces with a substantially uniform, spot-free spread of wall washer light consisting of: an elongated metal shell structure defining a pivoted head lighting device, said shell structure having an upper corner transition section and a lower front opening; a concave metallic light reflector within said shell structure extending over the length thereof; a high intensity electric lamp tube positioned centrally within said shell structure between said reflector and said front opening; a tempered glass lens spanning the front opening of said shell structure;
a terminal cross-tubular swivel member seated within and held by said gripping means for adjustable rotation therein, said swivel member being interconnected to an end of the support arm of said lighting device, the external diameter of said cross-tubular swivel member and the internal diameter of the semi-circular tube gripping means being substantially equal whereby rotation of said swivel member within said gripping means to position the pivoted head of said lighting device and the wall washer light illumination therefrom is only accomplished by overcoming the rotational friction resistance between said swivel member and said gripping means.
