Core troffer snap in and grounding assembly

A troffer-based lighting arrangement comprising end plates and a lighting unit configured between said end plates, wherein the lighting unit comprises a grounding point and head ends, wherein the end plates are associated with the respective head ends via connectors, wherein the lighting unit and end plates are in physical contact with each other for providing grounding continuity between the lighting unit and the end plates, and which connectors comprise head end locking tabs and end plate locking slots, wherein the locking tabs reside in the respective locking slots, the troffer-based lighting arrangement further comprising a troffer, wherein the troffer comprises side elements and said end plates defining a trough-like space for engaging at least part of said lighting unit, and wherein the lighting unit and said end plates are configured in interference fit for providing grounding continuity between the lighting unit and the end plates;

• wherein the lighting unit comprises a housing comprising cutouts, wherein the end plates comprise catching tabs, wherein the troffer-based lighting arrangement further comprises connectors which connectors provide grounding continuity between the lighting unit and the end plates, and which connectors comprise said catching tabs and cutouts configured in physical contact.

A troffer comprising side elements and end plates defining a trough-like space for engaging at least part of a lighting unit, wherein the end plates comprise end plate locking slots for engaging locking tabs comprised by said lighting unit, wherein the end plates comprise protruding elements that protrude from the end plates and which are configured for an interference fit with the lighting unit for providing grounding continuity between the lighting unit and the end plates.

A lighting unit comprising a grounding point and head ends, wherein the head ends comprise head end locking tabs for protruding locking slots of a troffer, which troffer comprises end plates, and which troffer is configured to engage at least part of said lighting unit, the lighting unit further comprising a housing, wherein the housing comprises cutouts for providing together with catching tabs of said troffer a physical contact configuration for providing grounding continuity between the lighting unit and the end plates.

A method of assembling a troffer-based lighting arrangement, the method comprising providing the troffer according to 5 and the lighting unit, moving the lighting unit into the trough-like space until the locking tabs reside in the respective locking slots, wherein the end plates comprise protruding elements that protrude from the end plates, and wherein the method further comprises moving the lighting unit into the trough-like space until the lighting unit is in an interference fit with protruding elements.
