A lighting device for illuminating exhibit, display and work surfaces with a substantially uniform wall washer light
. The device includes an elongated molded plastic housing having a front opening, a high intensity electric lamp tube positioned centrally within the housing, and an elongated concave metallic wall washer light reflector within the housing extending over the length thereof and positioned between the electric lamp and the rear of the housing to reflect light from the lamp outwardly through the front opening of the housing. The reflector has edge portions along its length impinging upon the edges of the housing along its length at its front opening for supporting the reflector. The reflector includes an extension of at least one of its edge portions to provide a strip of reflector metal external of the plastic housing whereby during use of the lighting device heat generated by the lamp within the housing and absorbed by the reflector is conducted thereby to the extension strip of reflector metal and radiated therefrom to maintain the plastic housing of the lighting device at a temperature well below its melting point.
In a lighting device for illuminating exhibit, display and work surfaces with a substantially uniform wall washer light as claimed in claim 1 wherein there is provided an extension of the edge portion of the reflector on both sides thereof to provide strips of the reflector metal external to the plastic housing of the lighting device for radiating heat therefrom.
In a lighting device for illuminating exhibit, display and work surfaces with a substantially uniform wall washer light as claimed in claim 1 wherein the molded plastic housing of the lighting device is provided with a multiplicity of molded-in air vent slots for the movement of air within the housing between said housing and said reflector for convection cooling of said device.
