Abstract
Light apparatuses and lighting systems are described. According to one aspect, a light apparatus includes a plurality of light sources individually configured to emit light in a respective primary direction, and wherein the light sources are configured such that the primary directions of the light emitted by the light sources are at different angles with respect to a common plane, and a lens configured to direct the light from the light sources to a surface of an object which is to be illuminated.
Claims26
A light apparatus comprising:
- a plurality of light sources individually configured to emit light in a respective primary direction, and wherein the light sources are configured such that the primary directions of the light emitted by the light sources are at different angles with respect to a common plane;
- a lens configured to direct the light from the light sources to a surface of an object which is to be illuminated;
- and wherein the light sources are arranged in a plurality of groups, and the light emitted from different ones of the groups only illuminate respective different regions of the object.
A light apparatus comprising:
- a plurality of light sources individually configured to emit light in a respective primary direction;
- a lens comprising:
- a curved input surface which is configured to receive the light from the light sources;
- and an output surface which is configured to direct the light from the light sources to a surface of an object which is to be illuminated;
- wherein the primary directions of the light emitted by at least some of the light sources are substantially orthogonal to a plurality of different locations of the curved input surface of the lens;
- and wherein the light sources are arranged in a plurality of groups, and the lens is configured to direct the light emitted from the different groups to respective different regions of the surface of the object which is to be illuminated.

A lighting system comprising:
- a light apparatus configured to emit light in a defined shape which is different than a shape of a surface of an object which is to be illuminated, wherein the light apparatus comprises:
- a plurality of light sources arranged in a plurality of different groups;
- and a lens configured to receive light emitted from the light sources of the different groups and configured to direct the light of the different groups to respective different regions of the surface of the object which is to be illuminated;
- and a mount configured to position the light apparatus with respect to the surface of the object which is to be illuminated such that the shape of the light which is emitted from the light apparatus substantially corresponds to the shape of the surface of the object when the light is received at the surface of the object.

A light apparatus comprising:
- a plurality of light sources individually configured to emit light in a respective primary direction, and wherein the light sources are configured such that the primary directions of the light emitted by the light sources are at different angles with respect to a common plane;
- a lens configured to direct the light from the light sources to a surface of an object which is to be illuminated;
- a diffuser configured to widen the light emitted by individual ones of the light sources;
- and wherein an input surface of the diffuser is curved and the primary directions of the light emitted by at least some of the light sources are orthogonal to a plurality of different locations of the curved input surface of the diffuser.
