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.

Abstract

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.
