Abstract
An overhead LED light fixture including a base member with a vertical sleeve secured to the top of the base member for alignment with a pass-through opening. The fixture has a driver-tray assembly with a bottom member engageable with the base member at the pass-through opening, a vertical driver-support structure extending upwardly therefrom, at least one driver secured to the support structure, and the driver-tray assembly is slideably received within the vertical sleeve. When used as a canopy light, the driver-tray assembly is removable from below the canopy to facilitate servicing, upgrading or replacing of components.
Claims17
An overhead LED light fixture comprising:
- a base member having a top and a bottom, the base member including an outward frame and defining a pass-through opening;
- a sleeve secured at the top of the base member for alignment with the pass-through opening;
- and
- a driver-tray assembly having a bottom member engageable with the base member at the pass-through opening, a driver-support structure extending upwardly therefrom, and at least one driver secured to the support structure, the driver-tray assembly being slideably received within the sleeve,
- whereby the driver-tray assembly is removable from below the frame to facilitate servicing.
An LED light fixture for installation with respect to an overhead canopy having a canopy sheet with a fixture-receiving opening therethrough, the fixture comprising:
- a base member having a top, a bottom, and a flange for engagement with the canopy sheet, the base member defining a pass-through opening;
- a vertical sleeve secured at the top of the base member for alignment with the pass-through opening;
- and
- a driver-tray assembly having a bottom member engageable with the base member at the pass-through opening, a vertical driver-support structure extending upwardly therefrom, and at least one driver secured to the support structure, the driver-tray assembly being slideably received within the vertical sleeve,
- whereby the driver-tray assembly is removable from below the canopy to facilitate servicing.
An LED light fixture for installation with respect to an overhead canopy having a canopy sheet with a fixture-receiving opening therethrough, the fixture comprising:
- a base member having a top, a bottom, and a flange for engagement with the canopy sheet, the base member defining a pass-through opening;
- at least one light bar secured with respect to the base member;
- a heat sink secured above and in contact with the light bar(s);
- a vertical sleeve secured at the top of the base member for alignment with the pass-through opening;
- a junction box secured atop the sleeve and having downwardly-facing plug connectors;
- a driver-tray assembly having a bottom member engageable with the base member at the pass-through opening, a vertical driver-support structure extending upwardly therefrom, at least one driver secured to the support structure, and upwardly-facing plug connectors mating with the downwardly-facing plug connectors, the driver-tray assembly being slideably received within the vertical sleeve,
- whereby the driver-tray assembly is removable from below the canopy to facilitate servicing.
A method for servicing or replacing the driver(s) of an LED light fixture installed with respect to an overhead canopy, the canopy having a canopy sheet and a fixture-receiving opening therethrough, the method comprising the steps of:
- providing a fixture including:
- a base member having a top, a bottom, and a pass-through opening;
- a vertical sleeve secured to the top of the base member in alignment with the pass-through opening;
- a junction box secured atop the sleeve and having downwardly-facing plug connectors;
- and a driver-tray assembly having a bottom member engageable with the base member, a vertical driver-support structure extending upwardly therefrom, at least one driver secured to the support structure, and upwardly-lacing plug connectors mating with the downwardly-facing plug connectors, the driver tray assembly being slideably received within the vertical sleeve;
- disengaging the bottom member of the driver-tray assembly from the base member;
- slideably withdrawing the driver-tray assembly from the vertical sleeve and, in starting such withdrawal, disconnecting the upwardly-facing plug connectors from the downwardly-facing plug connectors;
- servicing or replacing the driver(s);
- and
- slideably reinserting the driver-tray assembly into the vertical sleeve until the upwardly-facing plug connectors are reconnected with the downwardly-facing plug connectors.
An LED light fixture comprising:
- a base member having a first side from which fixture light is emitted and an opposite second side, the base member including an outward frame and defining a pass-through opening;
- a sleeve secured at the second side of the base member for alignment with the pass-through opening;
- and
- a driver-tray assembly having a base-engageable member at the pass-through opening, a driver-support structure extending therefrom in a direction away from the base member, and at least one driver secured to the support structure, the driver-tray assembly being slideably inserted within the sleeve,
- whereby the driver-tray assembly is removable by withdrawal through the pass-through opening to facilitate servicing.
