Arc-shaped hexagram cone graphical LED substrate and LED chip

The invention discloses an arc-shaped hexagram cone graphical LED substrate. Patterns of the substrate are formed by multiple arc-shaped hexagram cones which are arranged on the surface of the substrate and are identical in shape, any horizontal section of each arc-shaped hexagram cone is an arc-shaped hexagram, and each arc-shaped hexagram is a closed graph formed by surrounding of six circular arc sections which are connected end to end. The invention further discloses an LED chip comprising the arc-shaped hexagram cone graphical LED substrate. By the arc-shaped hexagram cone graphical LED substrate and the LED chip, light emitting efficiency of an LED is improved greatly, so that external quantum efficiency of the LED is improved.
