有木有人知道这句怎么翻译的，LED方面的

原句是这样的“In home use, where carrying capacity matters - on an edge of a stair for instance - the use of profiles is the common solution”? ? 主要是“the use of profiles”这个不懂 整段是这样的The carrying capacity of strips is generally very low. Hey-duty strip lights are not usually sold for home use, but much rather for commercial use on ships and in factories for instance. In home use, where carrying capacity matters - on an edge of a stair for instance - the use of profiles is the common solution. 各位大侠走过路过不要放过啊~~~~~~~~~~~~~
