LIGHT SOURCE COMPRISING A LIGHT EMITTER ARRANGED INSIDE A TRANSLUCENT OUTER ENVELOPE
First Claim
1. A light source comprising a light emitter arranged inside a translucent outer envelope,the translucent outer envelope being connected to a base, and further comprising a symmetry axis, an imaginary base-plane being defined substantially perpendicular to the symmetry axis and intersecting with a connection point being part of the translucent outer envelope, the connection point being a light transmitting part of the translucent outer envelope at an interface between the translucent outer envelope and the base at a furthest distance from a center (M) of the translucent outer envelope,the light emitter comprising a light emitting device and a translucent inner envelope at least partially surrounding the light emitting device, wherein the light emitting device is arranged on a substantially flat circuit board arranged substantially parallel to the imaginary base-plane, the translucent inner envelope comprising a diffuser for diffusing at least a part of the light emitted by the light emitting device, a diameter of the translucent inner envelope being smaller than a diameter of the translucent outer envelope,the light emitter being arranged inside the translucent outer envelope at a distance from the imaginary base-plane away from the base.

Abstract
The invention relates to a light source (10, 12) comprising a light emitter (20) arranged inside a translucent outer envelope (30, 32). The light emitter comprising a light emitting device (40) and comprising a translucent inner envelope (50) at least partially surrounding the light emitting device, the translucent inner envelope comprising a diffuser. A diameter (di) of the translucent inner envelope is smaller than a diameter (do) of the translucent outer envelope. The translucent outer envelope is connected to a base (60) not being translucent. The translucent outer envelope further comprises a symmetry axis (S). An imaginary base-plane (P) is defined substantially perpendicular to the symmetry axis (S) and intersects with a connection point (C) being part of the translucent outer envelope. The connection point is a light transmitting part of the translucent outer envelope at an interface between the translucent outer envelope and the base at a furthest distance from a center (M) of the translucent outer envelope. The light emitter is arranged inside the translucent outer envelope at a distance from the imaginary base-plane away from the base.
An effect of the light source according to the invention is that the emission profile of the light source according to the invention is increased.
