Patent attributes
A fire rated lighting housing (can) has: (a) a bottom that is open; (b) a top that is at least mostly closed or entirely closed; (c) a sidewall that runs from the bottom to the top; and (d) a fire-retarding material that is physically touching at least some portion of the sidewall when the sidewall is in a cool-state. The cool-state is when a temperature of the housing is at or below a predetermined normal operating temperature for the housing. This fire rated lighting housing, with the fire-retarding material, is configured to slow a fire from a lower floor reaching an above located adjacent floor with a minimum predetermined fire rating, which may be at least one (1) hour or more. Additionally, the top and the sidewall at least mostly enclose an internal-volume that is configured to directly house a light emitting element, like a LED (light emitting diode).
