Abstract
A sub-assembly of a light-emitting device package and/or a light-emitting device package, the package comprising a cavity filled with an encapsulant, are disclosed with means preventing the encapsulant delamination. The means comprise an expansion volume within the light-emitting device package, together with means allowing the encapsulant to flow from the cavity into the expansion volume as the encapsulant expands, and to flow back into the cavity as the encapsulant contracts during heating and cooling of the light-emitting device package.

A sub-assembly for a light-emitting device package, the sub-assembly comprising:
- a support member comprising an upper face adapted to be attached to a reserved area of a light-transmissive cover;
- a bottom face adapted to be attached to a reserved area of a substrate;
- and at least one opening.
A sub-assembly for a light-emitting device package, the sub-assembly comprising:
- a light-transmissive cover comprising a reserved area adapted to be attached to an upper face of a support member;
- and at least one groove introduced into the reserved area.
A sub-assembly for a light-emitting device package, the sub-assembly comprising:
- a substrate comprising an area reserved for placement of a light-emitting device sub-assembly on the substrate;
- and at least one groove introduced into the reserved area.
A sub-assembly for a light-emitting device package, the sub-assembly comprising:
- a substrate comprising an area reserved for placement of a light-emitting device sub-assembly on the substrate;
- and at least one opening introduced inside the reserved area.
A light-emitting device package, comprising:
- a substrate;
- a support member;
- a light-transmissive cover;
- and
- an expansion volume connected with the inside of a cavity, the cavity being delimited by the substrate, the support member, and the light-transmissive cover.
