求翻译：对于小户型家庭而言，要让有限的空间发挥最大的功能，选择可以一物两用的灯具，不仅起到照明的作用，还能增加一重功用。让你既能省钱，又能节省空间，一举两得。是什么意思？

For small families, to have limited space for the most features, selection of dual-use of lighting, not only play the role of lighting, also increases the weight function. You can save money and save space, two birds with one stone.
