Abstract: The present disclosure relates to methods and devices for accessing a service device in a local area network. One example method includes sending a first request message to a first router, receiving a first feedback message sent by the first router, and accessing at least one service device by using a communication address of an electronic device in a second network. The first request message is used to request the communication address of the electronic device in the second network. The first feedback message is used to indicate the communication address of the electronic device in the second network.

Abstract: A light emitting device includes a light-emitting laminate and an insulating reflective structure. The insulating reflective structure includes n pairs of dielectric layers stacked on the light-emitting laminate. Each of the n pairs of dielectric layers includes a first material layer and a second material layer. The first material layer has a first refractive index, and the second material layer has a second refractive index that is greater than the first refractive index of the first material layer. For each pair of dielectric layers among m1 pairs of dielectric layers out of the n pairs of dielectric layers, the first material layer has an optical thickness that is greater than that of the second material layer, where 0.5n?m1?n, and n and m1 are natural numbers greater than 0.

Abstract: Provided are an LED chip and a light emitting device, which include a light emitting epitaxial layer, a first insulating layer covering the light emitting epitaxial layer, and a first pad and a second pad located on the first insulating layer. Each of the first pad and the second pad includes a stress buffer layer, a nickel metal layer, and a protective layer. The stress buffer layer includes aluminum metal layers; and by adjusting the thickness distribution of the aluminum metal layers, an aluminum metal layer closest to the nickel metal layer is set to be the thickest, and the aluminum metal layers are thickened, especially the thickness of the aluminum metal layer closest to the nickel metal layer is greater than or equal to the thickness of the nickel metal layer, therefore, the ductility and tensile property of aluminum metal are utilized to play a role in stress buffering.

Abstract: A method for reducing power consumption of a mobile terminal and a mobile terminal are provided. The method includes: A mobile terminal establishes a Wi-Fi connection to an electronic device by using a Wi-Fi module; the mobile terminal interacts with a server by using the Wi-Fi connection; if the mobile terminal doesn't send or receive a packet within a first time period, the mobile terminal controls the Wi-Fi module to enter a sleep state; and after the Wi-Fi module enters the sleep state, if the mobile terminal needs to send a heartbeat packet, the mobile terminal may establish a Bluetooth connection to the electronic device by using a Bluetooth module, and send the heartbeat packet by using the Bluetooth connection.
