Detailed Description

The invention is further described with reference to the following specific drawings and examples.

As shown in fig. 2: the utility model provides an avoid stress concentration's punching press supporting structure, wherein: the LED lamp comprises a first plane 1, a second plane 2 and a third plane 3, wherein the first plane 1, the second plane 2 and the third plane 3 are all provided with notch parts, and a fourth plane 4 is formed at the intersection of the first plane 1, the second plane 2 and the third plane 3.

Wherein: first plane 1 is the rectangle, and lower right-angle side and left right-angle side both sides intersection set up first breach portion, first breach portion accounts for the area on first plane and is 5 ~ 10%.

Wherein: the second plane 2 is a right triangle, a second notch portion is arranged at the intersection of the two right-angle sides, and the second notch portion occupies 5-10% of the area of the second plane.

Wherein: the third plane 3 is a rectangle, a third notch part is arranged at the intersection of two sides of the upper right-angle side and the left right-angle side, and the third notch part accounts for 5-10% of the area of the third plane 3.

Wherein: the fourth plane 4 is in the shape of a regular triangle.

Wherein: the angles of the first upper edge of the fourth plane 4, the lower right-angle edge of the first plane and the left right-angle edge of the first plane are both 110-140 degrees.

Wherein: the angles of the first side edge of the fourth plane 4 and the two right-angle edges of the second plane are both 110-140 degrees.
