摘要： A light-emitting device having at least one spacer located at a bottom surface is disclosed. In two other embodiments, an electronic display system and an electronic system having such light-emitting device are disclosed. The light-emitting device comprises a plurality of leads, a light source die, and a body. The body encapsulates a portion of the plurality of leads and the light source die. The body has a least one side surface and a bottom surface. The at least one spacer is located at the bottom surface. In use, the light-emitting device is attached to a top surface of a substrate. The spacer is configured to create an air vent between the bottom surface and the top surface of the substrate when the light-emitting device is attached to, and the spacer is in contact with the substrate.

摘要： A flash module includes a point light source, a lens assembly, an actuator mechanism, and a control system. The lens assembly includes a lens that is positioned in front of the point light source. The actuator mechanism enables adjustment of the distance between the lens assembly and the point light source. The control system is provided to flash the point light source. A camera including a flash module, and a method for illuminating an object during flash photography, are also disclosed.
