Abstract: A mouse device includes a casing, at least one aspheric light guide plate and a light source. The casing includes an upper cover and a base. The upper cover includes at least one lateral surface. The aspheric light guide plate is installed on the lateral surface of the upper cover. Each aspheric light guide plate includes a light input surface and a light output surface. The light input surface and the light output surface are not in parallel with each other. The light output surface is aligned with the corresponding lateral surface of the casing. The light source is installed on the light input surface of at least one aspheric light guide plate. The light source emits light beams. After the light beams are inputted into the aspheric light guide plate through the light input surface, the light beams are outputted from the light output surface.

Abstract: A light source module includes a supporting substrate, plural light-emitting unit and a light mixing structure. The light mixing structure is disposed on the supporting substrate. The light mixing structure includes plural crooked light mixing channels. After the light beams emitted by the light-emitting unit are introduced into the corresponding light mixing channel, the light beams are mixed together in the corresponding light mixing channel, and the mixed light beams are outputted from the corresponding light mixing channel. Moreover, an electronic device with the light source module is provided.

Abstract: A housing structure for an electronic device includes a light-transmissible housing body, a first light-shielding layer, a second light-shielding layer, a protective layer and an engraved trench. The first light-shielding layer is formed on a second surface of the light-transmissible housing body. The engraved trench is formed in the second surface of the light-transmissible housing body and not covered by the first light-shielding layer. The second light-shielding layer is formed on a first surface of the light-transmissible housing body. The protective layer is formed over the second light-shielding layer. A pattern corresponding to the engraved trench is visible.
