Abstract

The present invention relates to a heat sink structure and a flexible light-emitting device with heat sink structures. The heat sink structure according to the present invention dissipates heat through a heat sink part. A hooking part on one end of the heat sink structure hooks a fixing part of another heat sink structure for forming flexible and bendable heat sink structures. Bending the heat sink structures gives a first nonlinear structure. The flexible light-emitting device can be disposed on the heat sink structures. The heat generated by the flexible light-emitting device can be removed by the heat sink structures. The heat sink structures can adapt to lamps with various designs. Then the design freedom and reliability of lamps can be improved.

Claims22

Dependent claims

A heat sink structure, comprising:

a body, having a heat sink part disposed below;
a hooking part, including a first bending part connected to one end of said body, the other end of said first bending part extending downwards to form one end of a first extending part, and the other end of said first extending part extending inwards and then upwards to form a hook;
a fixing part, disposed corresponding to said hooking part, including a second bending part, one end of said second bending part of said fixing part formed by extending the other end of said body downward, the other end of said second bending part extending downwards to form a second extending part, and said second bending part including a hole;
wherein said heat sink part further includes an extension and bending mechanism having a first bending part, a second bending part and a third bending part;
said first bending part of said extension and bending mechanism is extended downwards to said second bending part of said extension and bending mechanism;
said second bending part of said extension and bending mechanism is extended horizontally to said third bending part of said extension and bending mechanism;
and said third bending part of said extension and bending mechanism extends upwards and against said body.
