ILLUMINATION DEVICE
An illumination device (100) is provided, comprising a light source (110), an envelope (120) adapted to at least partially enclose the light source, and a positioning member (130) adapted to position the light source within the envelope. The positioning member can be arranged to assume a first state...

| description | An illumination device (100) is provided, comprising a light source (110), an envelope (120) adapted to at least partially enclose the light source, and a positioning member (130) adapted to position the light source within the envelope. The positioning member can be arranged to assume a first state in which the light source is positioned at a first distance (d1) from an inner surface portion (123) of the envelope and a second state in which the light source is positioned at a second distance (d2) from the inner surface portion. The positioning member comprises a shape-memory material adapted to shift the positioning member from the first state to the second state as the shape-memory material is exposed to an external stimulus such as a temperature or magnetic field exceeding a predetermined threshold value. Since the second distance is smaller than the first distance, the light source can be moved towards a wall of the envelope and hence the efficiency of heat dissipated from the light source via the envelope may be increased. |
