| Summary: | The invention provides a cavity type surface focusing guide device. The guide device is provided with a plurality of reflecting walls defining a cavity with a large inlet and a small outlet, wherein an inner side surface of the reflecting wall is a reflecting surface, at least one of a plurality of reflecting walls is an inclined reflecting wall, a stepped wave guide structure body is formed on aninner side of the inclined reflecting wall, and the stepped wave guide structure body is provided with a plurality of wave guide triangular prisms which are arranged in sequence to form a structuralequivalent or effect-raising cavity type surface focusing guide device (structural generalized Fresnel guide device). Compared with an original solid cavity type surface focusing guide device, the surface focusing wave guide device is advantaged in that the guide device is simple, visual, convenient and the like, is easy to design and manufacture, can easily achieve large-scale parallel connectionand series connection comb |
