A method for realizing diversified illumination through optical fiber cladding design is characterized in that a plurality of positions in a single large-diameter optical fiber are removed, an opening is formed at the position where the cladding is removed, the refractive index and the incident angle do not meet the total reflection condition, partial reflection and partial transmission occur, wherein the transmitted light beam forms an illumination light source of the point, and each opening on the optical fiber path is equivalent to providing a point light source, so that diversified illumination modes are formed.

And a specially designed lampshade can be arranged at each point of the light source formed by removing the cladding, so that the decorative effect with complex patterns can be obtained.

The principle of the invention is that the optical fiber light transmission utilizes the design of a specific fiber core and a cladding to realize the total reflection of an optical signal in the fiber core, the optical signal is transmitted from a fiber head to a fiber tail almost without loss, when a crack occurs at a certain position in an optical fiber path, the total reflection condition is destroyed, and partial light leaks from the position to form light leakage. If the active light leakage design is performed by using the crack, multi-point illumination can be obtained on one optical fiber.

In the invention, the cladding is removed at a certain position in the single large-diameter optical fiber, so that the refractive index and the incident angle at the point do not meet the total reflection condition, and partial reflection and partial transmission can occur, wherein the transmitted light beam forms an illumination light source of the point, as shown in fig. 1.

The cladding is removed at a certain position in a single thick-diameter optical fiber, and different material structure designs are arranged on the cladding, so that the emergent illuminance, the emergent light direction and the emergent spectrum of each illumination point are designed differently.
