Abstract
The invention relates to a light source () comprising a light emitter () arranged inside a translucent outer envelope (). The light emitter comprising a light emitting device () and comprising a translucent inner envelope () at least partially surrounding the light emitting device, the translucent inner envelope comprising a diffuser. A diameter (d) of the translucent inner envelope is smaller than a diameter (d) of the translucent outer envelope. The translucent outer envelope is connected to a base () 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.
