  • Patent number: 11556187
    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.

  • Publication number: 20210247032
    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.

  • Patent number: 10791642
    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.

  • Publication number: 20110062332
    Abstract: The present invention discloses a charge-coupled device monitor, comprising a lighting device, at least one charge-coupled unit and a processing unit. The lighting device comprises an infrared light emitting diode, an electrical conducting unit and a light guiding unit. The infrared light emitting diode receives a power to emit a light. The electrical conducting unit is positioned on a side of the infrared light emitting diode, electrically connecting to the infrared light emitting diode to provide the power. The light guiding unit, positioned on the other side of the infrared light emitting diode, changes the projecting profile of the light to a predetermined projecting profile, which comprises at least one straight edge. The charge-coupled unit receive the light emitted by the lighting device in the predetermined projecting profile and transforms the light to at least one electrical signal.
