Abstract
A fluorescent light fixture or luminaire having a housing which has hinge assemblies which pivotally support a mounting plate. The hinge assembly allows the mounting plate on which the lamps and ballasts are mounted to be pivoted to a generally vertical service position or latched by detents in a horizontal use position within the housing. The lens frame is also latched by detents and is pivotal to a vertical position for access to the housing interior. A selected number of lamp sockets can be selectively secured to the plate to receive the lamps. Reflectors and lamp stand-offs may be secured to the mounting plate at bendable tabs formed in the mounting plate. The light fixture is adapted for use with standard or high efficiency compact lamps.
Claims10
A light fixture for lamps comprising:
- (a) a housing having a side wall forming an enclosure, said housing having an open bottom;
- (b) first hinge members provided on the interior of said housing;
- (c) a mounting panel having opposite sides and ends, said mounting panel having an upper and lower surface, socket means associated with said mounting panel for mounting at least one lamp on the lower surface thereof and further including second hinge members cooperative with said first hinge members;
- (d) first detent means on said housing side wall and selectively engageable with said mounting panel whereby said mounting panel may be pivoted from a maintenance and installation position in which said mounting panel is generally suspended in a vertical position from said housing to a use-position in which said mounting panel is maintained by said first detent means in a generally horizontal position across said open bottom and
- (e) a lens panel hinged to said housing below said mounting panel and second detent means on said side wall selectively engageable with said lens panel whereby said lens panel may be pivoted from a maintenance and installation position in which said lens panel is generally suspended in a vertical position from said housing to a use-position in which said lens panel is maintained by said first detent means in a generally horizontal position across said open bottom of said housing.
A method of mounting a fluorescent fixture in a housing comprising:
- (a) providing a housing with a first hinge means;
- (b) providing a mounting panel having second hinge means associated therewith, said mounting panel having opposite top and bottom surfaces;
- (c) securing ballast means to said housing;
- (d) securing lamp sockets to the mounting panel in selected positions to mountably position at least one lamp extending along the bottom surface of said mounting panel;
- (e) suspending said mounting panel from said housing in a generally vertical position with said first and second hinge means in engagement;
- (f) completing electrical connections between the ballast and a source of power;
- (g) installing reflectors disposed between said lamps and said mounting panel wherein said reflectors are retained in place by extending at least one bendable tab integrally formed in said panel into retaining engagement with said reflectors;
- and
- (h) pivoting the panel to a generally horizontal position within said housing and latching the panel in an operative position at detent means.
A method of mounting a fluorescent fixture in a housing comprising:
- (a) providing the housing with a first hinge means;
- (b) providing a mounting panel having second hinge means associated therewith, said mounting panel having opposite top and bottom surfaces;
- (c) securing ballast means to said housing;
- (d) securing lamp sockets to the mounting panel in selected positions to mountably position at least one lamp along the bottom surface of said mounting panel;
- (e) suspending said mounting panel from said housing in a generally vertical position with said first and second hinge means in engagement;
- (f) completing electrical connections between the ballast and a source of power;
- (g) pivoting the mounting panel to a generally horizontal position within said housing and latching the mounting panel in an operative position at first detent means;
- and
- (h) providing a lens panel below said mounting panel, said lens panel being pivotally secured to said housing and being securable in a generally horizontal position with respect to said housing by second detent means.
