In this arrangement, the installing member  340  can be flush with a surface of the cabinet body  100  as far as possible, and the lighting power-taking system in the cabinet may also enhance a certain industrial aesthetic feeling. 
     In one embodiment, in order to further control the lamp  300  to achieve a certain lighting effect, the cabinet lighting power-taking system may further include a controller (not shown) through which the wire-distribution box  210  is connected to the lamps  300 . The controller is configured to control the luminous color temperature or brightness of the lamps  300  and to control the opening or closing of the lamps  300 . 
     In some application scenarios, the brightness, color temperature and continuous flashing time of the lamps  300  need to be adjusted to meet various lighting requirements of users. The controller in this embodiment can adjust the luminous color of the lamps  300  according to a preset program of a system, for example, in a first preset time range, the lamps  300  are controlled to emit red light, in a second preset time range, the lamps  300  are controlled to emit yellow light, in a third preset time range, the lamps  300  are controlled to emit white light, and in a fourth preset time, the lamps  300  are controlled to be powered off to stop emitting light, and the like. The specific control method of the controller is not limited here. 
     The foregoing is only an alternative embodiment of this application and is not thus limiting the scope of this application.
