A cover (22) for a lighting fitting (10) intended to be mounted in a panel (12) includes a light-transmitting part (30) of a heat-resistant material and a flange (32) which extends at least partially around the light-transmitting part (30). The cover (22) is arranged to be fitted over a lighting fitting (10) installed in a panel (12) so that light from the fitting (10) can pass through the light-transmitting part (30). The flange (32) lies adjacent to the panel (12) and includes a material (50) which is arranged in use to inhibit the passage of fire in a region between the flange (32) and an adjacent panel (12). A lighting fitting (10) suitable for mounting in a panel (12) is also disclosed. The lighting fitting (10) includes a body (20) in which a lamp (21) may be mounted, a light-transmitting part of a heat-resistant material arranged so that light from the lamp can pass through the light-transmitting part, and a flange (26) which extends at least partially around the body (20) of the lighting fitting (10). The flange (26) includes a material (27) which is arranged in use to inhibit the passage of fire in a region between the flange (26) and the panel (12). |
