The invention provides a support frame structure, an LED device and a support frame array, wherein the support frame structure comprises a support base plate and a conductor sheet group; the side annular peripheral surface of the support base plate comprises two long edge surfaces in mutual deviating arrangement and wide edge surfaces in mutual deviating arrangement; the conductor sheet group is embedded in the bottom of the support base plate; the partial surface is exposed to the wide edge surface position so as to form the side edge exposed surface; the side edge exposed surface comprises an electrode metal surface and a plating layer metal surface connected with each other; a metal coating is formed on the plating layer metal surface. The problems of unreasonable arrangement mode and poor assembly stability between the support base plate and the conductor sheet of the support frame structure for manufacturing the LED device in the prior art, the conductor sheet can be easily corroded so that the conduction performance of the conductor sheet and the integrated attractive appearance of the support frame structure can be influenced are solved. The support frame structure realizingthe economical performance and functional reliability is not provided in the prior art, so that the practicability of the LED device and the support frame array is poor.
