The present application relates to a method and an apparatus for controlling a device, a smart home device and system and a storage medium the device may be a lighting device. The method for controlling a device comprises: receiving a data stream including data for playing audio; acquiring reference data corresponding to a device control command controlling the device to perform one or more functions; determining whether at least a portion of the data in the data stream matches the reference data; and controlling, in case at least a portion of the data in the data stream matches the reference data, the device to perform one or more of the functions according to the corresponding device control command.

Disclosed are a method and apparatus for storing data. The method includes: acquiring data to be stored; converting the data to be stored from an initial data type to a target data type, a data length corresponding to the target data type being less than that corresponding to the initial data type; and storing the data to be stored of the target data type to a database. In the method according to the present disclosure, a storage space occupied by the data to be stored in the database is greatly reduced. In addition, the method according to the present disclosure is performed prior to lossy or lossless data compression storage of the data to be stored in the related art. That is, on the basis of a compression ratio when the data to be stored is stored in the related art, the present disclosure further improves a compression effect of the data to be stored by reducing the data length when the data to be stored is stored, and further saves storage resources of the database.

A method of preparing nanostructured single crystal silver, comprising placing a high-conductive molded porous active carbon containing chloride ions, which has been reductively treated, into a silver-containing precursor solution. After several hours at room temperature, the nanostructured single crystal silver grows on the surface of the active carbon. The silver-containing precursors and appropriate amount of chlorine provide a crystal nucleus and a slow stable crystal growth environment which are required for single crystal silver growth, and said nanostructured silver single crystals could be obtained with various morphologies by controlling the concentration of the silver-containing precursor solution and the growth time. The method of the invention is an environmentally friendly synthesis method with the nanostructured single crystal silver grows on the surface of the molded porous active carbon at room temperature, which is pollution-free and does not need any additives.

A three phase rectifier rectifies received three phase a.c. power to generate a ripple d.e. voltage. A power distribution bus conveys distribution power comprising the ripple d.c. voltage or an a.c. voltage derived therefrom to a location of an LED based lamp that is distal from the three phase rectifier. Additional circuitry disposed with the LED based lamp drives the LED based lamp using the distribution power.
