Abstract

A cabin light includes a panel coupled with a light source. The panel includes a pair of longitudinal portions extending along a longitudinal axis of the cabin light, a first lateral portion extending between the longitudinal portions along a lateral axis of the cabin light, and a second lateral portion extending between the longitudinal portions along the lateral axis. Each longitudinal portion includes a first surface and a second surface disposed at an offset from the first surface. The first lateral portion defines a first length and includes a first raised surface. The second lateral portion defines a second length, and includes a second raised surface. The cabin light also includes cover in alignment with the light source. The cabin light further includes a switch disposed between the cover and the second lateral portion.

First claim

What is claimed is:

1. A cabin light for a machine, the cabin light comprising: a panel adapted to couple with a light source, the panel including: a pair of longitudinal portions extending along a longitudinal axis of the cabin light, each longitudinal portion including a first surface, a second surface at an offset from the first surface, and a first width, wherein the first surface defines a second width, such that the first width is greater than the second width by a factor of at least two; a first lateral portion extending between the pair of longitudinal portions along a lateral axis of the cabin light, the first lateral portion defining a first length along the longitudinal axis, wherein the first lateral portion includes a first raised surface extending along at least a portion of the first length; and a second lateral portion extending between the pair of longitudinal portions along the lateral axis of the cabin light, the second lateral portion being disposed opposite the first lateral portion, the second lateral portion defining a second length along the longitudinal axis, wherein the second lateral portion includes a second raised surface extending along at least a portion of the second length; a cover fixedly coupled to the panel, wherein the cover is in alignment with the light source, such that the cover allows passage of light emitted by the light source therethrough; and a switch between the cover and the second lateral portion of the panel in a longitudinal direction of the panel, wherein the panel further includes an intermediate portion between the cover and the switch in the longitudinal direction of the panel, wherein the cover includes a first cover surface, a second cover surface, and a third cover surface between the first cover surface and the second cover surface, each of the first, second, and third cover surfaces extending from the first side of the cover to the second side of the cover, each of the first cover surface and the second cover surface being inclined with respect to the third cover surface which is substantially planar, wherein the switch includes a first switch surface, a second switch surface, and a third switch surface extending between the first switch surface and the second switch surface, each of the first switch surface and the second switch surface being inclined with respect to the third switch surface which is substantially planar, and wherein, in the longitudinal direction of the panel, the first cover surface is aligned with the first switch surface, the second cover surface is aligned with the second switch surface, and the third cover surface is aligned with the third switch surface.

2. The cabin light of claim 1 , wherein the cover extends between the first lateral portion and the intermediate portion, the cover defining a first side extending along the lateral axis and disposed adjacent to the first raised surface of the first lateral portion, such that the first side includes a plurality of first linear surfaces, the cover further defining a second side extending along the lateral axis and disposed adjacent to the intermediate portion, such that the second side includes a plurality of second linear surfaces.

3. The cabin light of claim 1 , wherein the second surface of each longitudinal portion, the first lateral portion, the second lateral portion, the intermediate portion, and the switch include a glossy surface finish.

4. The cabin light of claim 1 , wherein the first surface of each longitudinal portion and the cover includes a polished surface finish.

5. The cabin light of claim 1 ,
wherein the panel further includes a first side surface orthogonal to the first lateral portion,
wherein the panel further includes a second side surface orthogonal to the second lateral portion, such that the first side surface is substantially parallel to the second side surface, and
wherein each of the first side surface and the second side surface includes a polished surface finish.

6. The cabin light of claim 1 ,
wherein the cabin light is adapted to be removably coupled with an adapter, and
wherein the adapter is adapted to be removably coupled with an operator cabin of the machine, the adapter including:
a first continuous surface extending along an outer perimeter of the adapter; and
a second continuous surface extending along an inner perimeter of the adapter, the first continuous surface being spaced apart from the second continuous surface, the adapter defining a central opening that at least partially receives the cabin light based on a coupling of the cabin light with the adapter, wherein the panel is adapted to contact the second continuous surface based on the coupling of the cabin light with the adapter.

7. The cabin light of claim 6 ,
wherein the first continuous surface defines at least two through-openings, and
wherein each of the at least two through-openings receives a corresponding mechanical fastener fix removably coupling the adapter with the operator cabin of the machine.

8. The cabin light of claim 6 ,
wherein the first continuous surface includes a glossy surface finish, and
wherein the second continuous surface includes a polished surface finish.

9. The cabin light of claim 1 ,
wherein the first cover surface and the second cover surface are inclined in a first direction, from the third cover surface toward the panel, and
wherein the first switch surface and the second switch surface are inclined in a second direction, from the third switch surface away from the panel.

10. A cabin light assembly for a machine, the cabin light assembly comprising: a cabin light including: a panel adapted to couple with a light source, the panel including: a pair of longitudinal portions extending along a longitudinal axis of the cabin light, each longitudinal portion including a first surface, a second surface at an offset from the first surface, and a first width, wherein the first surface defines a second width, such that the first width is greater than the second width by a factor of at least two; a first lateral portion extending between the pair of longitudinal portions along a lateral axis of the cabin light, the first lateral portion defining a first length along the longitudinal axis, wherein the first lateral portion includes a first raised surface extending along at least a portion of the first length; and a second lateral portion extending between the pair of longitudinal portions along the lateral axis of the cabin light, the second lateral portion being disposed opposite the first lateral portion, the second lateral portion defining a second length along the longitudinal axis, wherein the second lateral portion includes a second raised surface extending along at least a portion of the second length; a cover fixedly coupled to the panel, wherein the cover is in alignment with the light source, such that the cover allows passage of light emitted by the light source therethrough, wherein the cover includes a first cover surface, a second cover surface, and a third cover surface between the first cover surface and the second cover surface, each of the first, second, and third cover surfaces extending from the first side of the cover to the second side of the cover, each of the first cover surface and the second cover surface being inclined with respect to the third cover surface which is substantially planar; and a switch between the cover and the second lateral portion of the panel, wherein the switch includes a first switch surface, a second switch surface, and a third switch surface extending between the first switch surface and the second switch surface, each of the first switch surface and the second switch surface being inclined with respect to the third
