Abstract
A fluorescent light fixture is disclosed which is modular in construction and capable of accommodating different types and numbers of light tubes. The light fixture includes a first and a second socket bridge which include a plurality of socket mounting holes in a first and a second row to accommodate different lengths of light tubes as well as varying numbers and locational positions of the light tubes in the fixture.
Claims20
A light fixture for use in receiving and supporting at least one electrically powered light tube, the light fixture comprising:
- an elongate base defining a longitudinal axis along the length of the base and a lateral axis along a width of the base substantially perpendicular to the longitudinal axis;
- a first universal light socket bridge extending along the lateral axis and connected to the base, the first socket bridge having a plurality of light tube socket holes spaced apart in alignment along the lateral axis in a first row and a second row positioned outward from the first row along the longitudinal axis;
- and
- a second light socket bridge positioned opposite the first socket bridge along the longitudinal axis and connected to the base, the second socket bridge extending along the lateral axis and having a first row of light socket holes aligned along the lateral axis with the first and second rows of socket holes in the first socket bridge, wherein the first and the second socket bridges are readily adaptable to accept a desired number and varying length of the at least one light tube through selective use of the first and the second rows of socket holes in the first socket bridge and the first row of socket holes in the second socket bridge.

A light fixture for use in receiving and supporting at least one electrically powered fluorescent light tube, the light fixture comprising:
- a housing having an elongate base defining a longitudinal axis along a length of the base and integral angled side panels extending along a lateral axis along a width of the base substantially perpendicular to the longitudinal axis, the base and the side panels defining an interior cavity for receipt of the at least one light tube, the base further defining a plurality of ballast mounting holes for universal mounting of at least one ballast to provide power to the chosen number and type of the at least one fluorescent light tube;
- a plurality of integrally formed vents extending away from the housing and each defining a vent opening in communication with the interior cavity, the plurality of vent openings positioned so that each of four respective directions along the longitudinal and the lateral axes includes at least one vent opening directed toward the respective direction and substantially perpendicular to the respective direction;
- and
- a first and a second universal light socket bridge positioned in the interior cavity separated along the longitudinal axis and each extending along the lateral axis, each of the first and the second socket bridges are connected to the housing and define a plurality of light tube socket holes in a first row spaced apart and alignment along the lateral axis and a second row positioned outward from the first row along the longitudinal axis and in respective alignment with the other holes in the second row along the lateral axis, wherein the first and the second socket bridges are readily adaptable to accept a desired number and varying length of the at least one light tube through selective use of the first and the second rows of socket holes in the first and the second socket bridges.

A method of assembling a universal light tube fixture comprising the steps of:
- providing an elongate base defining a longitudinal axis along a length of the base and a lateral axis substantially perpendicular to the longitudinal axis;
- mounting a universal first socket bridge to the base, the first socket bridge having a plurality of light tube socket holes spaced apart and in alignment along the lateral axis in a first row and a second row positioned outward from the first row along the longitudinal axis and in alignment with the other holes in the second row along the lateral axis;
- mounting a second socket bridge to the base opposite the first socket bridge along the longitudinal axis, the second socket bridge having a plurality of light socket holes positioned in a first row aligned along the lateral axis with the first and the second rows of socket holes in the first socket bridge;
- selecting a number and a length of light tubes to be used in the light fixture;
- selecting a number and a type of ballasts compatible with the selected number and the length of light tubes;
- selecting the socket holes from the first and the second rows of socket holes in the universal first socket bridge to accommodate the number and the lengths of the selected light tubes;
- selecting the socket holes in the second socket bridge to accommodate the number of the selected light tubes;
- mounting light tube sockets in the selected socket holes in the first and the second socket bridges corresponding to the selected number and the length of light tubes in electrical communication with the ballasts;
- and
- mounting the selected number and the length of light tubes in the light sockets.
