LIGHTING DEVICE FOR A LIGHT SOURCE

The present disclosure relates to a color tunable lighting device comprising at least one light source (302), a symmetry axis (306) and an envelope (304). The at least one light source (302) is disposed on a base (301) extending within a plane and the envelope (304) is disposed at least above the ba...

Zusammenfassung:	The present disclosure relates to a color tunable lighting device comprising at least one light source (302), a symmetry axis (306) and an envelope (304). The at least one light source (302) is disposed on a base (301) extending within a plane and the envelope (304) is disposed at least above the base (301) and defines a cavity (305) extending along the symmetry axis (306). The at least one light source (302) is arranged at a distance X from the symmetry axis (306) along a radial direction relative to the symmetry axis. The plane is arranged to intersect the symmetry axis (306). The distance X may be at least 50% of a total distance between the symmetry axis (306) and an edge of the envelope (304), or a projection of the edge of the envelope (304) on the plane in which the base (301) extends, as seen along the radial direction. A curvature of the envelope (304) is monotonically increasing with an increasing distance from the base (301).
