LIGHT SOURCE COMPRISING A LIGHT EMITTER ARRANGED INSIDE A TRANSLUCENT OUTER ENVELOPE |
摘要 |
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. |
