A portable lighting device adapted to provide an area light, said device including a body having a battery housing to hold batteries to power said device. The device includes a light panel functioning as a lens to act as an area light emitter, characterized in the said light panel is slidable into and out of said body, said light panel being constructed of a substantially flat panel portion.

Lighting device construction

A near-field lens is provided. The lens includes a lens body positioned about an optical axis. The lens body includes an input surface for receiving light from a light source and defined by a focusing surface and a convex hyperbolic surface. The lens body also includes an output surface through which light exits the lens body and a lateral surface extending between the convex hyperbolic surface and the output surface. The focusing surface is configured to collimate light along the optical axis towards the output surface and the convex hyperbolic surface is configured to substantially collimate light towards the lateral surface to be internally reflected towards the output surface.
