1. An illumination device comprising:
- a light source arranged to generate light,a carrier, comprising at least one carrier part, arranged to support said light source, said light source being in thermal contact with said carrier,an envelope enclosing said light source and said carrier,wherein the carrier is arranged in physical contact with the envelope for dissipating heat out of said illumination device,wherein the envelope includes at least two enveloping parts which, when joined together, form said envelope, andwherein a curved outer contour defined by the at least one carrier part matches at least a majority of a curved inner contour defined by an inner surface of at least one of the at least two enveloping parts in a direction parallel to a longitudinal axis of the illumination device from a position adjacent a portion of the at least one of the at least two enveloping parts that is insertable into a socket to an opposite side of the illumination device.

Abstract
The present invention discloses an illumination device (100). The illumination device (100) comprises a light source (110) arranged to generate light, a carrier (120) arranged to support the light source and an envelope (130) enclosing the light source and the carrier. The envelope comprises at least two enveloping parts which, when joined together, form the envelope. Further, the carrier is arranged in thermal contact with at least one of the enveloping parts for dissipating heat out of the illumination device.

12. An illumination device comprising:
-
a light source arranged to generate light, a carrier, comprising at least one carrier part, arranged to support said light source, said light source being in thermal contact with said carrier, an envelope enclosing said light source and said carrier, wherein the carrier is arranged in thermal contact with the envelope for dissipating heat out of said illumination device, wherein the envelope includes at least two enveloping parts which, when joined together, form said envelope, wherein the carrier is arranged at a junction between the two enveloping parts, and wherein a curved outer contour defined by the at least one carrier part matches, at a widest portion of the envelope, a curved inner contour defined by an inner surface of at least one of the at least two enveloping parts in a direction parallel to a longitudinal axis of the illumination device from a position adjacent a portion of the at least one of the at least two enveloping parts that is insertable into a socket to an opposite side of the illumination device. - View Dependent Claims (13, 14, 15)

16. An illumination device, comprising:
-
a light source operable to emit light; a carrier in support of the light source, the light source being in thermal contact with said carrier; a multi-part envelope enclosing said light source and said carrier, wherein the carrier is arranged in physical contact with the envelope for dissipating heat out of said illumination device through the envelope; wherein the multi-part envelope includes at least two enveloping parts which are joined together to form the envelope, a curved outer contour defined by the carrier matches a curved inner contour defined by an inner surface of at least one of the at least two enveloping parts along a substantial portion of the multi-part envelope in a direction parallel to a longitudinal axis of the illumination device from a position adjacent a portion of the at least one of the at least two enveloping parts that is insertable into a socket to an opposite side of the multi-part envelope; and the multi-part envelope including at least one enveloping part and at least part of the carrier to form a single integrated part. - View Dependent Claims (17, 18, 19)
