Abstract
A lighting unit includes a fire resistant housing (11) that is adapted to be mounted within an aperture in a partition (2). The housing (11) is made from a material that has a melting point in excess of 1000° C. and has a front side and a rear side. An LED lighting element (17) is mounted within the fire resistant housing on the front side thereof, and a heat sink (21) is mounted on the rear side of the fire resistant housing. The lighting element (17) and the heat sink are mounted in thermal contact with the fire resistant housing to dissipate heat generated in use by the lighting. Heat generated in use by the lighting element (17) is transferred by conduction to the heat sink (21) via the fire resistant housing (11).
Claims21
A lighting unit including a fire resistant housing that is adapted to be mounted within an aperture in a partition, said housing having a front side and a rear side, a solid state lighting element mounted within the fire resistant housing on the front side thereof, and a heat sink for dissipating heat generated in use by the solid state lighting element, wherein the solid state lighting element is mounted in thermal contact with the fire resistant housing so that heat generated in use by the solid state lighting element is transferred by conduction into the fire resistant housing, and the heat sink is mounted in thermal contact with the rear side of the fire resistant housing to dissipate heat from the fire resistant housing, the arrangement being such that heat generated in use by the solid state lighting element is transferred by conduction to the heat sink via the fire resistant housing.
