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.

A vehicle dual-functional lighting module is provided, including a light guide layer having a top surface, a bottom surface and at least one side surface, one lateral solid-state light source located on the side surface of the light guide layer and emitting a first light in a first direction, and one direct light solid-state light source located below the light guide layer and emitting a second light selectively in a second direction. The first light is guided by the side surface and led out of the top surface to present a surface-illuminated surface light source. The first direction is substantially perpendicular to the second direction. The second light is emitted toward the top surface to present an intensified light source which is located in the surface light source to selectively enhance the illumination intensity locally of the surface light source. A vehicle dual-functional lighting set is also provided.

Light emitting devices

A direct emitting LED illumination module for eliminating chromatic dispersion improves a vehicular LED lamp to comply with related regulations. The LED illumination module includes a LED light source and a plano-convex lens. The LED light source is located at the focus of the plano-convex lens. The LED light source emits light to the plane of the plano-convex lens, and the light exits from the convex surface of the plano-convex lens. The plano-convex lens focuses the light to form a desirable light pattern. Besides, the plane of the plano-convex lens has a microstructure thereon to suppress the angular correlated color temperature deviation of the light pattern and eliminate chromatic dispersion.
