Light emitting device, in particular a lamp or lantern
First Claim
1. Light-emitting device, comprising a housing (11), at least one light source (12) and at least one lens system (13) to direct the light radiated by the light source, characterized in that the lens system (13) has a catadioptric lens with a zone which exhibits a light admission surface (33), a reflection surface (34) and a light emission surface (26), with the light emission surface (26) having a ring-shaped or at least partially ring-shaped circumferential configuration and that the light issues from the lens system (13) on all sides as a strip of light having a limited height.

Abstract
The invention relates to a latern with a housing, a LED as light source and a catadioptric lens as a lens system to direct the light radiated from the light source. The light source in the housing can be adjusted relative to the lens system. The light emerges from the lens systems on all sides as a narrow strip, i.e. limited in height.

19. Light-emitting device comprising a housing (11), at least one light source (12) and at least one lens system (13) to direct light radiated by the light source (12), characterized in that:
-
a. the lens system (13) comprises a catadioptric lens with a light admission surface (33), a reflection surface (34) and a ring-shaped or at least partially ring-shaped circumferential light emission surface (26); b. the lens system (13) further defines an optic axis; c. light coming from the light source (12) enters the lens system (13) approximately axially with respect to the optic axis or as an open cone; and d. the light emerges from the lens system (13) with respect to the optic axis in an approximately radial direction. - View Dependent Claims (20, 21)
