The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention and are not to be construed as limiting the present invention. The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in a variety of different configurations.

[0016] In the present invention, unless otherwise clearly specified and limited, terms such as "installed", "connected", "connected", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two components.

[0018] like Figure 1 As shown, a linear lighting system based on multi-mirror splicing in this embodiment includes an LED light source group, a converging lens group, an imaging lens group, and a wave lens 4. The LED light source group includes multiple LED light sources 1, which are mounted on a base and arranged linearly. The converging lens group includes multiple converging lenses 2, which are arranged one-to-one with the LED light sources 1. Each converging lens 2 is aligned with one LED light source 1, and the converging lens 2 is used to shape the light emitted by the LED light source 1; the imaging lens group includes multiple imaging lenses 3, which are arranged in parallel. Each imaging lens 3 is aligned with the same number of converging lenses 2, and each imaging lens 3 is aligned with two converging lenses 2. The imaging lens 3 is used to image the light beam of the LED light source onto the surface of the illumination target for illumination; there is one wave lens 4, which is arranged between the illumination target and the imaging lens group, and is used to shape the light beam passing through the imaging lens group into a straight light band. The linear array camera captures the illumination target through the linear lighting system, achieving ultra-long-distance imaging.

[0019] A linear lighting system based on multi-mirror splicing in this embodiment is used to generate a high-brightness linear lighting light band, which is achieved by using less than 10 large-aperture converging lenses; the wave lens shapes the light band so that it changes from scattered image points to a continuous light band.

[0020] In other embodiments, each imaging lens 3 is aligned with three or more converging lenses 2 .
