Lighting fixture

An enclosure for coupling to a ceiling fixture for a light source comprising:

• a plate moveable between a deployed position and an undeployed position;
• a spring arm coupled to the plate and configured to urge the plate toward the deployed position;
• and
• a fire resistant material coupled to the plate,
• wherein the spring arm includes a sloped region extending between the plate coupling end and the enclosure coupling end such that compression of the spring arm causes the spring arm to move towards a horizontal position.

A ceiling fixture comprising:

• an enclosure;
• a light source, at least a portion of the light source is received within the enclosure;
• a fire mitigation system coupled to the enclosure, the fire mitigation system comprising:
• a plate moveably disposed within the enclosure;
• a spring arm having an enclosure coupling end and a plate coupling end, the enclosure coupling end coupled to the enclosure and the plate coupling end coupled to the plate;
• and
• a fire resistant material;
• a ceiling catch pivotally coupled to the enclosure;
• and
• a catch lock configured to selectively restrain pivotal movement of the ceiling catch, wherein the catch lock includes a latching arm, a deformable arm, and a deformation channel extending between the latching arm and the deformable arm and the ceiling catch includes an arm passthrough through which at least a portion of the catch lock extends.
