1. A lighting apparatus, comprising:
a light source for emitting a light:
a light passing cover with a first ladder edge;
a back cover; and
a rim frame having an inner frame and a light source holder, wherein the back cover, the rim frame and the light passing cover define a concealed space, the light source is disposed in the light source holder in the concealed space, the inner frame defines a light opening for the light to escape from the lighting apparatus, the inner frame has a second ladder edge surrounding the light opening, wherein the back cover, the first ladder edge and the second ladder edge are arranged sequentially, wherein the first ladder edge and the second ladder edge press each other, wherein multiple ladder protrusion surfaces between the first ladder edge and the second ladder edge prevent water to enter the concealed space, wherein the rim frame has an extension socket for attaching a function module outside the concealed space, the extension socket provides a structural connection and wireless charging to the function module.
