Abstract

[Use of the article]; This invention is a light-emitting diode carrier for packaging light-emitting diode chips.; [Features of the invention]; As shown in the attached figures, the light-emitting diode carrier of the invention has a carrier body in the shape of a long rectangle; as shown in the three-dimensional figure and the top view, the carrier body has a cup groove that is concave downward from the top surface and has a long rectangular opening, and the four corners of the cup groove are all formed with a chamfered edge, and the diameter of the cup groove is in a downwardly tapered shape, wherein two concave rectangular groove areas are formed on the bottom surface of the cup groove, and there is a non-straight-line spacing area between the two groove areas. ;As shown in the bottom view, metal bumps extending from the bottom and protruding from the short sides of the bottom of the carrier body are symmetrically provided at the center of the two short sides of the bottom of the carrier body, and the metal bumps have two concave arc-shaped missing corners; in addition, there are two roughly rectangular metal heat dissipation areas between the two metal bumps at the bottom of the carrier body. ;This creation has not yet disclosed the public articles before the application date, and meets the new patent requirements of novelty and creativity, so a new patent application is filed in accordance with the law.
