Abstract

The utility model discloses an LED substrate set, comprising an outer ring substrate, a middle ring substrate and an inner ring substrate. The outer ring substrate, the middle ring substrate and the inner ring substrate are cut out of the same square base material. Recessed portions and protruding portions of an inner ring edge of the outer ring substrate are corresponding to protruding portions and recessed portions of an outer ring edge of the middle ring substrate in a one-to-one manner. Recessed portions and protruding portions of an inner ring edge of the middle ring substrate are corresponding to protruding portions and recessed portions of an outer ring edge of the inner ring substrate in a one-to-one manner. Due to the concave-convex design of the substrates, the distance between the inner ring edge and the outer ring edge of each substrate is increased, and thus reasonable distribution of LEDs is facilitated to achieve the optimal light distribution. Compared with the traditional circular substrate, the LED substrate set adopts the concave-convex design, and thus components on the substrate to connect LED chips are omitted, thereby saving materials. Four corners of the square base material can cut out a circular substrate respectively, and a central position of the square base material, which is surrounded by the inner ring substrate, can cut out a circular substrate at an upper part, a lower part, a left part and a right part respectively, and thus waste of the base material can be substantially reduced, and the use efficiency of the base material is maximized.
