The intumescent material has a shape complementary to a shape of the housing. The plate is positioned adjacent to the stepped surface and to an upper surface of the intumescent material.
Claims21
A recessed luminaire comprising:
- a housing supporting a light emitter and configured to be positioned at least partially through an aperture in a ceiling, the housing including a stepped surface;
- an intumescent material directly contacting an outer surface of the housing and having a shape complementary to a shape of the housing, the intumescent material having an upper surface substantially co-planar with the stepped surface along a first plane;
- and
- a plate coupled to the housing and to the intumescent material, the plate positioned in contact with the stepped surface and in contact with the upper surface of the intumescent material along the first plane.
A recessed luminaire comprising:
- an upper housing configured to house a driver;
- a lower housing coupled to the upper housing, the lower housing including a light emitter coupled to the driver and a reflector;
- a first intumescent material directly coupled to the lower housing and positioned radially outside of an outer surface of the reflector;
- and
- a second intumescent material positioned between the upper housing and the lower housing.
A luminaire for attaching through an aperture in a ceiling or wall of a structure comprising:
- a first housing having a first diameter smaller than the aperture and including a light emitter;
- a first intumescent material directly coupled to an outer surface of said first housing;
- a second housing having a second diameter smaller than said first diameter and coupled to a top surface of said first housing;
- and
- a second intumescent material coupled to said second housing proximate said top surface of said first housing.
