Lighting device with connector for add on electrical device
First Claim
1. A lighting device comprising:
- a solid state light source;
a first portion adapted to receive a direct or alternating current power source;
a second portion mounted on the first portion, the second portion having an outer surface, wherein at least a portion of the outer surface of the second portion is light transmissive for outputting light originating from the solid state light source;
a metal heat sink extending at least partly along the outer surface of the second portion, the metal heat sink arranged to be in thermal contact with the solid state light source; and
a connector arranged at a position on the metal heat sink for connecting an electrical device from outside of the lighting device, the position on the metal heat sink being on a part of the metal heat sink that extends along the outer surface of the second portion;
wherein a distance from the first portion to the connector is longer than a distance from the first portion to at least one light transmissive portion of the outer surface of the second portion.

Abstract
A lighting device (100, 600) comprises a first portion (110, 610), a solid state light source (120, 620), a second portion (130, 630), a metal heat sink (140, 640-641) and a connector (150). The first portion is arranged for electrically connecting the lighting device. The second portion is mounted on the first portion and has an outer surface, wherein at least a portion (131, 631) of the outer surface is light transmissive for outputting light originating from the solid state light source. The metal heat sink extends along the outer surface, and is arranged in thermal contact with the solid state light source. The connector is arranged at the metal heat sink for connecting an electrical device (160, 660). A distance (D1, D3, D4) from the first portion to the connector is longer than a distance (D5) from the first portion to at least one light transmissive portion (131, 631) of the outer surface.
