Cross light guide arrangement structure and super-long linear atmosphere lamp

The utility model discloses an arrangement structure of a crossed light guide and an ultra-long linear atmosphere lamp. The arrangement structure comprises a support, two lamp holders and the crossed light guide. According to the arrangement structure of the crossed light guide and the ultra-long linear atmosphere lamp adopting the technical scheme, the light-emitting initial sections of the two linear light guides are arranged in a crossed mode, the bending radius between the light inlet section and the light-emitting initial sections and the bending radius between the light-emitting initial sections and the light-emitting main body section can be greatly increased, meanwhile, bifurcation positions do not exist, and the light-emitting effect is improved. Therefore, the problem of light leakage is avoided, the consistency and uniformity of the overall brightness of the atmosphere lamp are guaranteed, the two linear light guides are each independently provided with one lamp holder, the overall brightness of th
