A light-emitting glazing assembly (100, 100', 100", 200, 200', 200", 300, 300a, 300b, 300c, 300d, 300', 700, 800, 900, 910, 920) for a door for a piece of refrigerating equipment comprising an insulating glazing unit having an external main face and an internal main face, the insulating glazing unit containing: - a first glazing unit comprising the external face and a first edge formed from edge faces (13a to 13d), said first glazing unit including a first glass sheet having a first main face and a second main face, the first face being the external face or the first sheet being laminated to another glass sheet or the first glazing unit being the central pane of a triple glazing unit; - a second glazing unit comprising the internal face and a second edge formed from edge faces (13a to 13d), said second glazing unit including a second glass sheet, having a third face and a fourth main face, the second and third faces being spaced apart by a first gas-filled cavity, the fourth face being the internal face or the second sheet being laminated to another glass sheet or indeed a third sheet made of glass is spaced apart from the second sheet by a second gas-filled cavity; - on the periphery of the second and third faces, a first polymeric seal forming a frame; - a light source external to the insulating glazing unit, said source preferably being chosen from: - light-emitting diodes each comprising a semiconductor chip having an emissive face, and - an optical fiber having a lateral portion forming the emissive zone, said light source external to the insulating glazing unit being optically coupled to one of the edge faces, referred to as the injection edge face, in order to propagate light by total internal reflection in the thickness of the first glazing unit, which then plays the role of a light guide; - a source carrier (20, 20') bearing the light source and not extending beyond the first edge in the direction of the external face and, which, for said diodes, is a printed circuit board; and - means for extracting the guided light, associated with the first glazing unit, in order to form at least one luminous zone; the glazing assembly furthermore comprising: - a part, referred to as a fastening part, adjacent to the injection edge face, and that is a profile placed along the periphery of the injection edge face; and - what is referred to as a bottom part (5, 5'), facing and spaced apart from the injection edge face, the light source then being housed between the bottom part and the injection edge face, the source carrier for the optical fiber possibly being the bottom part or the fastening part directly characterized in that the fastening part, making direct adhesive contact with the external edge face of the polymeric seal. - a first glazing unit comprising the external face and a first edge formed from edge faces (13a to 13d), said first glazing unit including a first glass sheet having a first main face and a second main face, the first face being the external face or the first sheet being laminated to another glass sheet or the first glazing unit being the central pane of a triple glazing unit;
