whereby the driver-tray assembly is removable from below the frame to facilitate servicing.

2. The fixture assembly of claim 1 wherein the LED driver-tray assembly is vertical and includes two vertically-secured drivers on the support structure.

3. The fixture assembly of claim 1 wherein the sleeve is vertical and serves as a cover enclosing the driver(s).

4. The fixture assembly of claim 1 wherein the bottom member of the driver-tray assembly includes a motion sensor with a lens exposed at the pass-through opening of the base member.

5. 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 and a bottom, and a flange for engagement with the canopy sheet, the base member defining a light-bar support region and a pass-through opening laterally offset therefrom, and including an outward frame surrounding the light-bar support region and 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.

6. The fixture assembly of claim 5 wherein the LED driver-tray assembly includes two vertically-secured drivers on the support structure.

7. The fixture assembly of claim 5 wherein the vertical sleeve is a cover enclosing the driver(s).

8. The fixture assembly of claim 5 wherein the bottom member of the driver-tray assembly includes a motion sensor with a lens exposed at the pass-through opening of the base member.

9. 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 and a bottom, and a flange for engagement with the canopy sheet, the base member defining a light-bar support region and a pass-through opening laterally offset therefrom, and including an outward frame surrounding the light-bar support region and 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.

10. The fixture assembly of claim 9 wherein the LED driver-tray assembly includes two vertically-secured drivers on the support structure.

11. The fixture assembly of claim 9 wherein the vertical sleeve is a cover enclosing the driver(s).

12. The fixture assembly of claim 9 wherein the bottom member of the driver-tray assembly includes a motion sensor with a lens exposed at the pass-through opening of the base member.

13. A method for servicing or replacing 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 and a bottom, the base member defining a light-bar support region and a pass-through opening laterally offset therefrom, and including an outward frame surrounding the light-bar support region and 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-facing 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.

14. 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 defining a light-bar support region and a pass-through opening laterally offset therefrom, and including an outward frame surrounding the light-bar support region and 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.

15. The fixture assembly of claim 14 wherein the LED driver-tray assembly is vertical and includes two vertically-secured drivers on the support structure.

16. The fixture assembly of claim 14 wherein the sleeve is vertical and serves as a cover enclosing the driver(s).

17. The fixture assembly of claim 14 wherein the base-engageable member including a motion sensor with a lens exposed at the pass-through opening.
