Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings.

[0048] like Figure 1 to Figure 2 As shown, it is a schematic diagram of the structure of the present invention. A matrix LED pixel light optical system for automotive lighting consists of a light source base 1, a matrix LED chip 2, a first lens 3, a second lens 4, and a third lens 5. , a fourth lens 7, a diaphragm 8, and an outer glass 9.

[0049] like image 3 Shown is a schematic diagram of the implementation of the optical system of the present invention. The system adopts a reverse design method, and the position of the LED chip is set as the image plane S1, and the light receiving surface is set as the object plane S13. There are 13 planes from the image plane to the object plane, namely S1 to S13.

[0050] The S1 is the light-emitting surface of the LED chip, and its length is 32mm and the width is 21mm. The structure of the matrix LED chip according to the ...
