| 摘要 |
The present invention discloses an illumination device (100) and a method (4000) for assembly of such an illumination device. 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. The method comprises the steps of mounting (4100) the light source in thermal contact with the carrier and enclosing (4200) the light source and the carrier with the envelope. The present invention is advantageous in that it provides a convenient design which facilitates the assembly of the illumination device. Further, the present invention is advantageous in that it provides an illumination device with improved heat transfer. |

1. A bulb-shaped illumination device comprising:
at least two light sources arranged to generate light, a carrier comprising two or more carrier parts, the carrier arranged to support said light sources, said light sources being in thermal contact with said carrier, and a bulb-shaped envelope enclosing said light sources and said carrier within an open interior space, the envelope integrated with a threaded annular socket, wherein said envelope comprises at least two enveloping parts which, when joined together, form said envelope and the surface of the illumination device, wherein the carrier is arranged in thermal contact with at least one of the enveloping parts for dissipating heat from said light sources out of said illumination device, the carrier extending inwardly from the at least one enveloping part, the carrier positioned to divide a light mixing space defined within the envelope into at least two compartments, the light sources positioned on each side of the carrier with a first light source on a first carrier side in a first compartment and a second light source on a second carrier side in a second compartment and facing away from said first light source in an outward direction of the envelope, and the envelope extending around the carrier and to the socket to form a heat sink and enclosing the first light source, the second light source, and the carrier and forming the bulb shape illumination device; wherein a curved outer contour defined by the two or more carrier parts matches a curved inner contour defined by an inner surface of at least one of the enveloping parts in a direction parallel to a longitudinal axis of the bulb-shaped illumination device from a top of the illumination device to a position adjacent a portion of the at least one enveloping part that is inserted into the threaded annular socket. |
