Abstract
A light fixture or troffer for directing light emitted from a light source toward an area to be illuminated, including a reflector assembly within which the light source is positioned; a housing defining at least one selectively enclosable ballast enclosure; and a ballast that is positionable in the at least one ballast enclosure.
Claims35
A light fixture having a linear light source in electrical communication with an external power source, comprising:
- a reflector assembly comprising an elongated base member having a first end edge and a spaced second end edge with, a first longitudinally extending side edge and, an opposed second longitudinally extending side edge extending from said first end edge to said second end edge, a base top surface, an opposed base bottom surface, and a base longitudinal axis extending between the first end edge and the second end edge of the base member;
- a housing having a first end wall connected to a portion of the first end edge of the base member, an opposed second end wall connected to a portion of the second end edge of the base member, and at least one angled cover having a first panel and a second panel, the first panel being connected to the second panel substantially along an angled edge, the first panel having a first side edge and the second panel having a second side edge, the first side edge of the first panel being connected to a portion of the first longitudinal side edge of the base member, the second side edge of the second panel connected to a portion of the base top surface of the base member, said angled cover extending between the first end wall and the second end wall of the housing so that portions of the first and second end walls, portions of the first angled cover and portions of the base top surface define a first ballast enclosure, wherein a portion of the at least one angled cover defines a first port adjacent the angled edge that is in communication with the first ballast enclosure, wherein at least a portion of the first port is defined in a portion of the first panel of the first angled cover and is spaced from the first side edge of said panel a predetermined distance, and wherein at least a portion of the first port is defined in a portion of the second panel of said angled cover;
- at least one ballast for electrically connecting the light source to the external power source, the at least one ballast being positioned in the first ballast enclosure;
- and
- a first closure plate configured for releasable connection to said angled cover such that, in a closed position, said closure plate is in substantial registration with the first port and the at least one ballast positioned in the first ballast enclosure can be selectively enclosed.

- a reflector assembly comprising:
- an elongated base member having a first end edge and a spaced second end edge with, a first longitudinally extending side edge and, an opposed second longitudinally extending side edge extending from said first end edge to said second end edge, a base top surface, an opposed base bottom surface, and a base longitudinal axis extending between the first end edge and the second end edge of the base member;
- and
- a first end face and an opposed second end face, each of the respective first and second end faces having a top edge and being positioned with respect to the base member such that a portion of the top edge of each respective end face is positioned in substantially overlying registration with a portion of the base bottom surface and spaced from the respective first and second edges of the base member;
- a housing having a first end wall connected to a portion of the first end edge of the base member, an opposed second end wall connected to a portion of the second end edge of the base member, and at least one angled cover having a first panel and a second panel, the first panel being connected to the second panel substantially along an angled edge, the first panel having a first side edge and the second panel having a second side edge, the first side edge of the first panel being connected to a portion of the first longitudinal side edge of the base member, the second side edge of the second panel connected to a portion of the base top surface of the base member, said angled cover extending between the first end wall and the second end wall of the housing so that portions of the first and second end walls, portions of the first angled cover and portions of the base top surface define a first ballast enclosure;
- and
- at least one ballast for electrically connecting the light source to the external power source, the at least one ballast being positioned in the first ballast enclosure.
