Light-Emitting Device and Luminaire Incorporating Same |
| abstract |
A light-emitting device includes a lens of refractive index n having a spherical exit surface of radius R and a luminous element positioned such that at least a portion of an edge of an emitting surface of the luminous element lies on a sphere of radius R/n opposite the exit surface, whereby that portion of the edge of the emitting surface is aplanatically imaged by the spherical exit surface. The light-emitting device may further include one or more reflective sidewalls arranged to reflect a fraction of light emitted from the luminous element before it is refracted by the exit surface. A luminaire incorporating a housing and a light-emitting device of this type is also provided, which may include one or more additional optical elements such as reflectors or lenses to further direct and shape light from the light-emitting device. |
