In this article, we study the two-body strong decays of the bottom mesons with the heavy meson effective theory in the leading-order approximation and obtain all the analytical expressions of the decay widths of the light pseudoscalar meson transitions among the S-wave, P-wave and D-wave bottom mesons. As an application, we tentatively assign the bottom meson as the 2S , 1D 1- and 1D states, respectively, and calculate the decay widths of the , , , and , which may be confronted with the experimental data in the future.
