Encapsulation structure of RGB (Red, Green and Blue) three-color LED (Light-Emitting Diode)

The invention discloses an encapsulation structure of an RGB (Red, Green and Blue) three-color LED (Light-Emitting Diode). The encapsulation structure disclosed by the invention comprises a heat sink aluminum substrate, an RGB three-color LED chip and a silicone lens, wherein the heat sink aluminum substrate is provided with a reflecting tank and an electrode plate; the RGB three-color LED chip is fixed on a bottom plane of the reflecting tank via solid crystal glue; a positive electrode and a negative electrode of the LED chip are connected to the electrode plate on the heat sink aluminum substrate via a gold wire; the silicone lens is covered above the reflecting tank and the RGB three-color LED chip; and a light outgoing side of the RGB three-color LED chip is inclined to the tank shape direction of the reflecting tank, so that the RGB three-color LED chip is integrally encapsulated. The LED encapsulated by the encapsulation structure disclosed by the invention has the advantages of being capable of randomly adjusting color temperature according to the requirements, emitting light by a large angle on a directing plane, being high in optical coupling efficiency and high in uniformity of light intensity distribution.
