Abstract: A two-part inductive connector comprises a primary part having a primary half core and a secondary part having a secondary half core, the primary part including first locking means which are engageable with second locking means on the secondary part, one of the primary or secondary parts further comprising a pin which is receivable in a recess formed in the other of the primary or secondary parts, the connector having an unlocked position in which the primary and secondary half cores are not aligned and in which the first and second locking means are not engaged, and a locked position in which the primary and secondary half cores are aligned and the first and second locking means engaged, the connector moving between the unlocked and locked positions by relative rotation of the primary and secondary parts about the pin.

Abstract: The invention relates to LED-based lamps, luminaires and lighting systems for buildings particularly, though not exclusively, for providing emergency light in the event of power failure. In particular it provides a light-emitting diode lamp comprising a support (26) and an array of light emitting diodes (58) on the support, an optical axis (72) passing through the middle of the array (58) and diodes increasing in number and increasing in inclination with distance from the optical axis (72). It also provides a luminaire (24) comprising a lamp as described above and a lens (30) having facets for generally un-deviated and un-reflected passage of light from off-axis diodes, and a building emergency lighting system comprising luminaires (24) as described above. In an alternative embodiment inclination of the light is through progressively increasing inclination of the facets.
