Abstract: A lateral light emitting atmospheric downlight includes a light body, a first light source module, a second light source module and a light guide module. An upper end and a lower end of the light body are respectively provided with a communicating opening, the first light source module is arranged around an inner wall of the light body, the light guide module is arranged in the light body, and a light exiting surface of the first light source module is opposite to the light guide module; the second light source module is arranged around an outer wall of the light body, and one side, away from the light body, of the second light source module emits light. With the design above, multi-directional light emission of the downlight is achieved.

Abstract: The present invention discloses a method for query of domain names of telephone numbers, e.g., E.164 numbers. The method comprises: in ENUM DNS (Electronic numbers to URI Mapping Domain Name System), dividing a domain name of a telephone number into a public domain name part and a digit domain name part; storing sequentially public domain name information separated by spacer(s) in the public domain name part and the data obtained by arranging digits in the digit domain name part in a preset order into nodes of a search tree according to storage rules of the search tree; on receiving a query request, the ENUM DNS obtaining the public domain name information of the domain name and finding the corresponding nodes according to search tree rules; obtaining the digits separated by spacer(s) in the domain name, arranging the digits into data in a prescribed order of the system, and finding the next-level nodes of the search tree.
