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.

摘要： A white light emitting device, a light bar and a light apparatus. A relative spectrum of the white light emitting device is ϕ(λ). A relative spectrum of a black body radiation with a corresponding color temperature is S(λ). An area normalization is performed on ϕ(λ) and S(λ) to convert an equal energy spectrum ϕ′(λ) of the white light emitting device and an equal energy spectrum S′(λ) of the black body radiation with the corresponding color temperature. A degree of similarity R of the equal energy spectrum of the white light emitting device and the equal energy spectrum of the black body radiation satisfies the following formula:
