Abstract
A lighting apparatus includes a light source, a light passing cover, a back cover and a rim frame. The light source is used for emitting a light. The light passing cover has a first ladder edge. The rim frame has an inner frame and a light source holder. The back cover, the surface rim 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. The first ladder edge and the second ladder edge are pressed by the back cover to press to each other. Multiple ladder protrusion surfaces between the first ladder edge and the second ladder edge prevent water to enter the concealed space.
