The lamp casing has a first sidewall, a second sidewall, a bottom wall and an upper connective structure, together they encloses a central space. The first sidewall has a first opening and the second sidewall has a hook groove. There is a second opening between the second sidewall and the bottom wall. The spring has a first end and a second end. A central portion of the strip-shaped spring can be latched by the hook groove. The first end of the spring is fixed by the first opening on the first sidewall. The second end of the spring has an internal recess structure.
