Claim:
1. A light-emitting device comprising: a heat sink having at least one first locking part, a planar mounting part, and two outer edges located proximate two sides of the mounting part, the at least one first locking part being shaped so as to form at least one locking slot between the mounting part and one of the two outer edges, the at least one locking slot having a planar inward bending part at an end of the at least one locking slot extending away from one of the outer edges of the heat sink, the inward bending part being parallel to the mounting part; a cover formed of an elastic, optically transparent material having at least one elastically deformable second locking part along an edge of the cover; and a light-emitting assembly mounted onto the mounting part, wherein the at least one second locking part pressingly engages with the at least one first locking part to form an enclosed cavity for the light-emitting assembly so that an entirety of the at least one second locking part is on a cavity side of the at least one first locking part, wherein the at least one second locking part has a pressing part pressing the light-emitting assembly in a first direction against the mounting part of the heat sink, wherein the at least one second locking part has a supporting part pressing the at least one second locking part against a first surface of the inward bending part of the at least one first locking part in a direction opposite to the first direction, the supporting part being disposed entirely in the at least one locking slot, the at least one second locking part having a counter connecting edge contacting a second surface of the inward bending part opposite the first surface of the inward bending part, and wherein the at least one second locking part has a first recessed arc-shaped part forming the pressing part, and wherein the at least one second locking part has a second recessed arc-shaped part forming the supporting part, the first recessed arc-shaped part and the second arc-shaped part being directly connected to one another to form an S-shape in cross-section.
