    摘要: Provided is a LED device and a backlight module. The LED device comprises a bracket, a LED chip and an encapsulation layer. A reflective cup is arranged on the bracket, and the LED chip is arranged in the reflective cup. The encapsulation layer encases and encapsulates the LED chip in the reflective cup, the encapsulation layer has a top surface of the encapsulation layer. The top surface of the encapsulation layer is located above a top surface of the reflective cup, and is a lens curved surface. In an on-state, the LED device has virtual cross sections passing through a geometrical center of the LED chip and perpendicular to a top surface of the bracket, in at least one of the virtual cross sections of the LED device, the LED device has luminous efficiency greater than or equal to 95% within a beam angle of at least 60°.

    摘要: A triangular-combination LED circuit board, comprising a plurality of triangular LED units, wherein vertexes of every six of the LED units are superimposed to jointly form a hexagonal central point such that every six of the LED units form a hexagonal LED array; the LED unit includes a substrate and pads disposed on the substrate; the pads include die bond pads; and three die bond pads are provided, respectively disposed at three vertexes of the triangular LED units. In the present invention, triangular LED units are set to form triangular LED devices which can be more densely arrayed on a PCB, so an LED display with LED devices arrayed at a smaller distance is generated, and pixel definition is strengthened. Meanwhile, in an LED circuit board, the LED units are closely arranged in a hexagonal shape, so the utilization rate of materials can be enhanced; moreover, a plurality of LED units can be bored at one time at the central point of the hexagon, and finally the LED devices can be quickly obtained by simple cutting, thus effectively enhancing the processing efficiency and reducing production cost.
