Abstract
The lamp includes an illumination source; and a housing structure having an inner wall forming an inner housing with an inner aperture, and outer wall forming an outer housing with an outer aperture. The inner housing encloses the illumination source, and the outer housing encloses the inner housing with the outer aperture arranged around the inner aperture so that light produced by the illumination source can exist the inner housing. A space between the inner and outer wall forms a thermal barrier between the illumination source and the exterior of the lamp. A first outlet is connected to the inner housing for air to flow from the inner aperture towards the first outlet. The lamp is used in a hyperspectral imaging system of a medicine inspection system.
Claims17
A lamp for hyperspectral imaging, the lamp comprising:
- an illumination source, the illumination source is a tube-shaped light source;
- an inner housing having a rectangular-shape or line shaped inner aperture, the inner housing containing the illumination source such that light produced by the illumination source can exit the inner housing through an inner aperture;
- an outer housing containing the inner housing, the outer housing including an outer aperture disposed around the inner aperture and a space between the inner housing and the outer housing forming a thermal barrier between the illumination source and an exterior of the lamp;
- and
- a first outlet, formed in a wall of the inner housing, the first outlet forming a connection between the inner housing and an outside of the lamp, such that a first gas flow entering the inner aperture can move towards the first outlet,
- wherein a longitudinal axis of the rectangular-shaped or line-shaped aperture being oriented substantially parallel to a longitudinal axis of the tube-shaped light source.
A hyperspectral imaging system comprising:
- a lamp and a hyperspectral imaging camera, wherein the lamp comprises:
- an illumination source;
- an inner housing including inner aperture, containing the illumination source such that light produced by the illumination source can exit the inner housing through an inner aperture;
- an outer housing containing the inner housing, the outer housing including an outer aperture disposed around the inner aperture and a space between an inner wall and an outer wall forming a thermal barrier between the illumination source and an exterior of the lamp, and a first outlet, formed in a wall of the inner housing;
- and
- a cooling system connected to the first outlet such that a first flow entering the inner aperture is propelled towards the first outlet.
A medicine inspection system comprising:
- a transport structure comprising a transport path for guiding one or more medicine objects;
- a hyperspectral imaging camera having a field of view including at least a portion of the transport path;
- and
- a lamp configured to illuminate the one or more medicine objects that are located in the field of view of the hyperspectral imaging camera, the lamp comprising:
- an illumination source;
- an inner housing including an inner aperture, containing the illumination source such that light produced by the illumination source can exit the inner housing through an inner aperture;
- an outer housing containing the inner housing, the outer housing including an outer aperture disposed around the inner aperture and a space between an inner wall and an outer wall forming a thermal barrier between the illumination source and an exterior of the lamp;
- and a first outlet, formed in a wall of the inner housing;
- and
- a cooling system connected to the first outlet, such that a first flow entering the inner aperture can move towards the first outlet.
