Abstract: A lighting system includes a lighting fixture having a wall having an opening therein, the opening being defined by edges of the wall. The lighting system further includes one or more louvers. Each louver includes a louver body having a first and a second end and grips for gripping the edges of the wall disposed at the first and second ends of the louver body to suspend the louver body across the opening. The grips are slidably movable to different points along the edges of the wall. A method of making a lighting system is also disclosed.

Abstract: A hinge construction particularly for pivotally connecting the housing and cover of an electrical enclosure together is preferably formed integrally as part of the lid and as part of the housing so as not to require separate fasteners or hinge pins, yet the hinge portions on both housing and cover are formed in a straight-draw die casting operation not requiring side cores. The housing includes two outwardly extending appendages, each carrying a laterally extending pin cantilevered in the same direction as the other pin and axially aligned therewith. One pin at its outer end carries an obstruction jutting transversely outwardly therefrom in a predetermined angular orientation. Hinge portions on the cover also include appendages, but in the form of a pair of outwardly lugs with a laterally extending hole in each which is axially aligned with the hole in the other lug.
