Principle of the utility model: the two welding positions are designed to be stepped, and there is no spatial limitation on the two welding points, the size of the chip can be enlarged, and the solid crystal is not limited by the spatial area; because the two welding points and the solid crystal position are not on the same horizontal plane, the two welding points are prevented from sticking to the solid crystal glue to cause a cold solder joint; the step shape effectively blocks the flux or harmful substances from penetrating along the joint gap between the plastic and the metal electrode plate, thereby improving reliability.

[0005] As an improvement, the first electrode plate, the second electrode plate and the plastic frame are integrally formed.

[0006] In order to solve the above technical problems, the second technical solution of the utility model is: an LED package, including a bracket and an LED chip arranged in the bracket, the bracket includes a plastic frame, the bottom of the plastic frame is provided with a first electrode plate and a second electrode plate, and an insulating strip is provided between the first electrode plate and the second electrode plate; a first solid crystal area is formed on the first electrode plate, a second solid crystal area is formed on the second electrode plate, a first welding platform formed by bending the first electrode plate is provided in the first solid crystal area, and a second welding platform formed by bending the second electrode plate is provided in the second solid crystal area; a first LED chip is provided on the first electrode plate, and two welding points of the first LED chip are provided on the first welding platform; a second LED chip is provided on the second electrode plate, and two welding points of the second LED chip are provided on the second welding platform. Principle of the utility model: the two welding positions are designed into a step shape, the two welding points do not have spatial limitations, the size of the chip can be enlarged, and the solid crystal is not limited by the spatial area; because the two welding point positions and the solid crystal position are not on the same horizontal plane, the two welding points are prevented from sticking to the solid crystal glue and causing a cold solder joint; the step shape effectively blocks the flux or harmful substances from penetrating along the joint gap between the plastic and the metal electrode plate, thereby improving reliability.

[0007] As an improvement, the first electrode plate, the second electrode plate and the plastic frame are integrally formed.

[0008] As an improvement, the first welding platform is higher than the first LED chip, and the second welding platform is higher than the second LED chip.

[0009] As an improvement, the width of the first welding platform is greater than the two welding points of the first LED chip, and the width of the second welding platform is greater than the two welding points of the second LED chip.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The second welding position is designed to be a step shape. There is no spatial limitation for the second welding point, the size of the chip can be enlarged, and the die bonding is not limited by the spatial area. Since the second welding point position and the die bonding position are not on the same horizontal plane, the second welding point is prevented from sticking to the die bonding glue and causing cold soldering. The step shape effectively blocks the flux or harmful substances from penetrating along the joint gap between the plastic and the metal electrode plate, thereby improving reliability.
