1. An ultraviolet (“UV”) emission device for a conveyor system, the UV emission device comprising:
a housing that is configured to attach to a frame of the conveyor system, the frame supporting a moveable surface of the conveyor system, such that a return surface of the moveable surface is located within an interior cavity of the frame, wherein the housing is further configured to attach to the frame within the interior cavity,
the housing having a lateral edge and a longitudinal edge, wherein:
the lateral edge is configured to extend across the return surface within the interior cavity,
the longitudinal edge is configured to extend along the return surface within the interior cavity, wherein a first end of the longitudinal edge is arranged at a first location on the frame and a second end of the longitudinal edge is arranged at a second location on the frame, wherein the lateral edge intersects the longitudinal edge at the first end,
the return surface contacts the longitudinal edge at the first end and at the second end, such that (i) the longitudinal edge has a first angle between the first end and the second end, and (ii) a portion of the return surface between the first end and the second end has the first angle, and
each of the longitudinal edge and the return surface has a respective incline, the respective inclines being in a particular direction with respect to the frame;
an energy emission element arranged within the housing;
a barrier bracket arranged along the lateral edge of the housing, the barrier bracket having a first position and a second position; and
an absorptive barrier supported via the barrier bracket, wherein the absorptive barrier is configured to contact, along the lateral edge of the housing, the return surface of the conveyor system, wherein:
in the first position of the barrier bracket, the absorptive barrier contacts the return surface of the conveyor system and the barrier bracket activates an interlock switch, and
in the second position of the barrier bracket, the barrier bracket deactivates the interlock switch.
