Abstract

A linear light fixture for use in a hazardous environment, the linear light fixture includes a housing body that defines a component compartment therein that is configured to receive electrical components. The linear light fixture also includes a light engine connected to the housing body and including a light emitting diode. The light engine is pivotable with respect to the housing body between a first position, wherein the light engine encloses the component compartment, and a second position, wherein access is provided to the component compartment. The light engine is separable from the housing body.

First claim

What is claimed is:

1. A linear light fixture for use in a hazardous environment, the linear light fixture comprising:
a housing body defining a component compartment therein configured to receive electrical components,
wherein the housing body includes opposite first and second sides extending longitudinally between opposite first and second ends thereof, and wherein a first handle is provided at one of the first and second sides of the housing body; and
a light engine connected to the housing body and including a light emitting diode, the light engine being pivotable with respect to the housing body between a first position, wherein the light engine encloses the component compartment, and a second position, wherein access is provided to the component compartment,
wherein the light engine is separable from the housing body, and wherein the light engine is pivotably attached to the housing body at the first side thereof.

2. The linear light fixture of claim 1 , wherein the light engine includes a sealed housing for isolating the light emitting diode from the hazardous environment.

3. The linear light fixture of claim 1 , wherein the light engine includes a plate having first and second opposite sides, wherein the first side of the light engine is pivotably connected to the housing body, and wherein a notch is formed at the second opposite side of the plate.

4. The linear light fixture of claim 3 , wherein the housing body includes a latching tab extending outwards therefrom.

5. The linear light fixture of claim 1 , wherein a second handle is provided at the other of the first and second sides of the housing body.

6. The linear light fixture of claim 1 , wherein the light engine is selectively locked in the first position via a latch such that the latch prevents the light engine from pivoting towards the second position.

7. The linear light fixture of claim 1 , wherein a hollow hub is provided at one of the first and second ends of the housing body and is configured to receive an electrical conduit therein.

8. The linear light fixture of claim 1 , wherein a hinge is provided at a side of the housing body and defines a pivot axis.

9. The linear light fixture of claim 8 , wherein the light engine includes a plate, and wherein a hinge pin is provided at a side of the plate.

10. The linear light fixture of claim 9 , wherein the hinge pin is removably received within the hinge such that the light engine is pivotable about the pivot axis between the first position and the second position.

11. The linear light fixture of claim 9 , wherein the plate includes opposite first and second surfaces, the light emitting diode being provided on the first surface, and the second surface facing the component compartment when the light engine is in the first position.

12. The linear light fixture of claim 10 , wherein the hinge pin is defined by a through-hole formed in the plate and disposed adjacent thereto.

13. The linear light fixture of claim 12 , wherein the hinge includes a vertical portion extending from the housing body and a curved portion at a distal end thereof, wherein the vertical portion of the hinge extends within the through-hole formed in the plate when the light engine is in the first position, and wherein the curved portion partially wraps around the hinge pin.

14. A linear light fixture for use in a hazardous environment, the linear light fixture comprising:
a housing body defining a component compartment therein configured to receive electrical components; and
a light engine connected to the housing body and including a light emitting diode, the light engine being pivotable with respect to the housing body between a first position, wherein the light engine encloses the component compartment, and a second position, wherein access is provided to the component compartment,
wherein the light engine is separable from the housing body,
wherein the light engine includes a plate having first and second opposite sides, wherein the first side of the light engine is pivotably connected to the housing body, and wherein a notch is formed at the second side,
wherein the housing body includes a latching tab extending outwards therefrom, and
wherein when the light engine is in the first position, the latching tab is received within the notch formed at the second side of the plate.

15. The linear light fixture of claim 14 , wherein the notch is a cut-out formed at an edge of the second side of the plate.

16. The linear light fixture of claim 14 , further comprising a latch secured to the plate, the latch and the notch collectively defining a pocket, wherein the pocket is configured to receive a protrusion of the latching tab.

17. The linear light fixture of claim 16 , wherein the latch is resiliently movable such that as the light engine pivots from the second position to the first position, the latch is moved away from the plate via a force imparted by the protrusion of the latching tab.

18. A linear light fixture for use in a hazardous environment, the linear light fixture comprising:
a housing body extending along a longitudinal axis and defining a component compartment therein, said component compartment being configured to receive electrical components, the housing body comprising:
first and second opposite sides extending along the longitudinal axis between first and second opposite ends of the housing body;
a hinge provided at the first side of the housing body and defining a pivot axis; and
a latching tab provided at the second side of the housing body;
a light engine removably connected to the housing body, the light engine comprising:
a plate having first and second opposite sides extending between first and second opposite ends thereof, wherein a notch is formed at the second side of the plate;
a light emitting diode provided on a first surface of the plate; and
a hinge pin provided at the first side of the plate,
wherein the hinge pin is removably received within the hinge such that the light engine is pivotable about the pivot axis between a first position, wherein the plate encloses the component compartment, and a second position, wherein access is provided to the component compartment,
wherein when the light engine is in the first position, the latching tab is received within the notch, and
wherein the plate includes a second surface, opposite to the first surface, that faces the component compartment when the light engine is in the first position.
