The present invention relates to a lamp structure, which comprises a light guide plate, a lamp plate, and a lamp housing. The light guide plate includes an inner loop, an outer loop, and an annular tortuous structure. The annular tortuous structure includes a plurality of top recesses and a plurality of bottom recesses. The plurality of top recesses and the plurality of bottom recesses are interlaced to give a continuous concave-convex structure. The lamp plate is disposed inside the inner loop. The lamp housing includes a top housing member and a bottom housing member. The top and bottom housing members are located on both sides of the lamp plate and disposed on the two loop openings of the inner loop and opposing to each other. Thereby, the light of the lamp plate illuminates outward via the shape and structure of the light guide plate.
