led light having a good heat dissipation effect

The present invention discloses an LED light source having a good heat dissipation effect, including one or more LED chips and the heat sink, the LED chip is directly connected by a thermally conductive adhesive to the upper surface of the radiator; on the heat sink the surface is also provided with a layer of a metal conductive film electrically connected to the respective network or power input of LED chips on the metal conductive film web is provided between the heat sink surface with an insulating film; the LED chip and the each node of said metal conductive film are connected by a metal wire network. The present invention is in direct contact with the substrate through the LED chip and the heat sink, thus greatly reducing the heat dissipation paths, thereby enhancing the heat dissipation effect. Further the present invention is a disposable heat sink, a light source, a lens integrated with the package is reduced from the normal process flow to the lamp.
