Abstract
The present invention features an integrated, electronic fluorescent ballast fixture which includes an electronic ballast packaged with a set of fluorescent lamp connectors into an integral fixture. The fixture has a circuit board that selectably supports up to four fluorescent lamps. The housing of the fixture id configured to receive a number of lamp connectors. The connectors are electrically, connected to the circuit board use wire and poke-in type connectors. When used with conventional, straight fluorescent lamps, a second set of sockets at the far end of the lamps are also connected to the circuit board using wires received in poke-in connector on the circuit board. The integrated ballast package also works with U-shaped lamps. The housing of the fixture is shaped to accommodate projecting electronic ballast components attached to the circuit board. The transformers and transistors of the circuit board may be thermally sinked, so that their heat is carried to the housing by thermally conductive means. The housing consists of two halves that are assembled together with snap-in action latches, making the fixture quickly and easily fabricated. The ballast fixture can be used wi…
