Techniques for directing ultraviolet energy towards a moving surface

An enclosed fixture for an ultraviolet (“UV”) emission element, the enclosed fixture comprising:

• a housing in which the UV emission element is arranged, the housing having a lateral edge configured to extend across a moveable surface of a conveyor system;
• a suspension bracket that is mounted to the housing via a biasing member, the suspension bracket extending in a direction across the moveable surface along the lateral edge, the suspension bracket further having a flange that extends in the direction along the lateral edge;
• a barrier bracket that is arranged along the lateral edge of the housing, the barrier bracket being arranged to contact the flange of the suspension bracket,
• the barrier bracket having a first position in which the barrier bracket applies pressure to the flange of the suspension bracket in a direction away from the moveable surface of the conveyor system, wherein the pressure applied by the barrier bracket extends the biasing member, and
• the barrier bracket having a second position in which the flange of the suspension bracket applies pressure to the barrier bracket in a direction towards the moveable surface of the conveyor system, wherein the pressure applied by the suspension bracket is applied via a contraction of the biasing member;
• and
• an absorptive barrier supported via the barrier bracket, wherein:
• in the first position of the barrier bracket, the absorptive barrier contacts the moveable surface of the conveyor system and the barrier bracket activates an interlock switch,
• in the second position of the barrier bracket, the barrier bracket deactivates the interlock switch.

An enclosed fixture, the enclosed fixture comprising:

• an energy emission element configured to produce ultraviolet (“UV”) energy output;
• a housing configured to attach within an interior cavity of a conveyor system, the housing including electrical contacts configured to receive the energy emission element, the housing further including a lateral edge and a longitudinal edge, wherein:
• the lateral edge is configured to extend across a moveable surface of the conveyor system within the interior cavity,
• the longitudinal edge is configured to extend along the moveable surface within the interior cavity, wherein a first end of the longitudinal edge is attached at a first location within the interior cavity and a second end of the longitudinal edge is attached at a second location within the interior cavity, wherein the lateral edge intersects the longitudinal edge at the first end,
• the moveable 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 moveable surface between the first end and the second end has the first angle, and
• each of the longitudinal edge and the moveable surface has a respective incline, the respective inclines being in a particular direction with respect to a frame of the conveyor system;
• a power regulator configured to provide power to the energy emission element via the electrical contacts;
• an absorptive barrier arranged along the lateral edge of the housing, wherein the absorptive barrier is configured to contact the moveable surface;
• and
• an interlock switch configured to determine a status of the contact between the absorptive barrier and the moveable surface, wherein:
• responsive to determining a closed status of the contact between the absorptive barrier and the moveable surface, the interlock switch performs a first modification of the power provided by the power regulator to the energy emission element, and
• responsive to determining an open status of the contact between the absorptive barrier and the moveable surface, the interlock switch performs a second modification of the power provided by the power regulator to the energy emission element.
