Abstract

Lighting fixtures having adjustable components configured to accommodate the application of force (e.g., from a moving patient bed) are provided. In one example embodiment, a lighting fixture can include a housing configured to house a light source. The lighting fixture can include a mounting bracket configured to attach with the housing to secure the housing to a surface. The mounting bracket can include a guide mechanism. The guide mechanism can define a guide channel. The housing is attachable to the mounting bracket such that at least a portion of the housing can move relative to the mounting bracket along the guide channel of the guide mechanism when a force is applied to the housing.

First claim

What is claimed is:

1. A lighting fixture comprising:
a housing configured to house a light source;
a mounting bracket configured to attach with the housing to secure the housing to a surface, the mounting bracket comprising a guide mechanism and a secondary bracket, the guide mechanism defining a guide channel, the secondary bracket being adjustable in at least one direction,
wherein the housing is attachable to the mounting bracket such that at least a portion of the housing is movable relative to the mounting bracket along the guide channel of the guide mechanism when a force is applied to the housing, and
wherein the housing is attachable to the secondary bracket such that the housing is movable relative to the mounting bracket in at least the one direction.

2. The lighting fixture of claim 1 , wherein the guide mechanism has a G-hook shape.

3. The lighting fixture of claim 1 , wherein the guide mechanism comprises a linear surface extending at a non-perpendicular angle from a back plate of the mounting bracket.

4. The lighting fixture of claim 1 , wherein the housing comprises an end cap, the end cap having a pin extending from a surface of the end cap.

5. The lighting fixture of claim 4 , wherein the guide mechanisms is configured to receive the pin of the end cap.

6. The lighting fixture of claim 5 , wherein the pin moves along the guide surface of the guide mechanism when the force is applied to the housing.

7. The lighting fixture of claim 1 , wherein the force comprises an upward vertical force.

8. The lighting fixture of claim 1 , wherein the lighting fixture comprises a control mechanism configured to alter movement of an object applying force to the lighting fixture.

9. The lighting fixture of claim 1 , wherein the lighting fixture is positioned within the vicinity of a patient bed.

10. The lighting fixture of claim 9 , wherein the lighting fixture comprises a control mechanism configured to alter the movement of the patient bed when the patient bed applies force to the lighting fixture.

11. The lighting fixture of claim 10 , wherein the control mechanism is configured to stop movement of the patient bed when the housing has moved a threshold distance.

12. The lighting fixture of claim 8 , wherein the control mechanism comprises a switch lever arm.

13. The lighting fixture of claim 12 , wherein the switch lever arm engages a pin extending from an end cap when the housing is attached to the mounting bracket.

14. A lighting fixture, comprising:
a housing configured to house a light source, the housing having an end cap, the end cap having a pin extending from a surface of the end cap;
a mounting bracket having a back plate that is attachable to mounting surface, the mounting bracket comprising a guide mechanism extending from the back plate, the guide mechanism defining a guide channel, the mounting bracket comprising a secondary bracket, the secondary bracket having a movable mechanism attached to the housing, the movable mechanism configured to move a distance range;
wherein the pin is received into the guide channel when the housing is attached to the secondary bracket, wherein the housing is movable relative to the mounting bracket when a force is applied to the housing such that the pin moves along the guide channel defined by the guide mechanism.

15. The lighting fixture of claim 14 , wherein the guide mechanism has a G-hook shape.

16. The lighting fixture of claim 14 , wherein the guide mechanism comprises a linear surface extending at a non-perpendicular angle from a back plate of the mounting bracket.

17. The lighting fixture of claim 14 , wherein the lighting fixture comprises a control mechanism configured to alter movement of an object applying force to the lighting fixture, the control mechanism comprising a switch lever arm, wherein the switch lever arm is disposed adjacent to the pin extending from the surface of the end cap.
