Abstract:
1. A light source comprising a housing containing an array of light emitting elements having a depth, and a fresnel prism disposed in front of the array to receive light from the array, the fresnel prism serving to divert light from the array to a direction oblique to the array, the light diverted by the fresnel prism thereby forming an output beam whose depth, measured transverse to the beam direction and in the same plane as the depth of the array, is smaller than the depth of the array, the arrangement of the array and of the fresnel prism being such that there is a line of sight which does not pass through the fresnel prism and which extends from at least part of the array to the exterior of the housing so that light is emitted by the light source along said line of sight as well as through the fresnel prism.
