The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, the light-variable light distribution structure provided in this embodiment is formed by an aluminum substrate printed circuit board 1, a patch type LED chip 1-1, a light distribution lampshade 2, and an aluminum alloy support 3, and the basic connection structure is as follows:

in the embodiment, the patch type LED chip 1-1 is soldered to the printed circuit board 1 of the aluminum substrate to form a light source module.

In this embodiment, the aluminum alloy support 3 is provided with a second hook 3-2 and a third hook 3-4 at the position where the aluminum substrate printed circuit board 1 is mounted, and an aluminum alloy support lamp panel fixing groove 3-3 is formed between the two hooks. The aluminum substrate printed circuit board 1 is arranged between the second clamping hook 3-2 of the aluminum alloy support and the third clamping hook 3-4 of the aluminum alloy support 3 and is fixed on the lamp panel fixing groove 3-3 of the aluminum alloy support through screws.

In the embodiment, the light distribution lampshade 2 is fixed with the first clamping hook 3-1 of the aluminum alloy support and the fourth clamping hook 3-5 of the aluminum alloy support on the aluminum alloy support 3 through the first clamping hook 2-1 of the light distribution lampshade and the second clamping hook 2-4 of the light distribution lampshade, and covers the light source module.

As shown in fig. 3, in the present embodiment, in order to realize that the light emitted by the patch LED chip 1-1 forms a starry sky effect through the convex light distribution lens 2-2 on the light distribution lampshade 2, the light distribution lampshade 2 is specially designed. The light distribution lampshade 2 is provided with an optical material substrate, a plurality of light distribution convex lenses 2-2 are arranged on a base surface of one side, facing the light source module, of the optical material substrate to form a lens group, and the light distribution convex lenses 2-2 are long in strip shape and are arranged in parallel. The light distribution convex lenses 2-2 are connected through a section of concave curved surface 2-3 to form a special-shaped light distribution lens. Meanwhile, the relation among the surface light spots of the surface light distribution lampshade 2, the surface light distribution convex lens 2-2 on the surface light distribution lampshade 1-1 of the patch type LED chip is also specially designed, and the focal length f of the surface light distribution convex lens 2-2 on the surface light distribution lampshade 2, the distance u from the patch type LED chip 1-1 to the surface light distribution convex lens and the light spots v of the surface light distribution lampshade 2 meet the following light distribution formula:
