Abstract
A panel lighting module includes a light guide plate which is intended for the outcoupling of light on at least one of its plate large faces, a light source arrangement having at least one light source arranged adjacent to a first plate narrow face of the light guide plate for coupling light into the first plate narrow face, and a biasing arrangement that resiliently biases the light source in the direction towards the first plate narrow face.
Claims18
A panel lighting module, in particular for fitting into a domestic cooling device, comprising:
- a light guide plate which is intended for the outcoupling of light on at least one of its plate large faces;
- a light source arrangement having at least one light source, in particular in the form of a light-emitting diode, arranged adjacent to a first plate narrow face of the light guide plate, for coupling light into the first narrow face of the light guide plate;
- and
- a biasing arrangement which resiliently biases the light source in the direction towards the first plate narrow face.
A method of making a panel lighting module, the method comprising:
- obtaining a light guide plate having plate edges wherein the light guide plate is intended for the outcoupling of light on at least one of its plate large faces;
- obtaining a module frame having two frame components, each having a plate edge region, wherein the two frame components when placed one on top of the other delimit between them a receiving space wherein at least one of the frame components has at least one groove that extends along the plate edge region and is open towards the receiving space;
- filling the at least one groove with a curable sealant such that the curable sealant protrudes over a groove edge of the at least one groove;
- and
- enclosing the light guide plate in the module frame at the plate edges of the light guide plate wherein the light guide plate projects into the receiving space causing the curable sealant in the at least one groove to come into contact with the light guide plate when the two frame components are joined together thereby ensuring good sealing against the ingress of moisture.
