Abstract:
1. An electronic device comprising: a first light source; a second light source; a first light guiding lens comprising a first light input surface and a first light output surface away from the first light input surface, the first light guiding lens being configured to receive light from the first light source through the first light input surface, and to guide the received light to the first light output surface; a second light guiding lens comprising a second light input surface and a second light output surface away from the second light input surface and close to the first light output surface, the second light guiding lens being configured to receive light from the second light source through the second light input surface, and to guide the received light to the second light output surface; a light shielding plate interposed between the first and second light guiding lenses, at least a portion of the light shielding plate having a height higher than the first and second light input surfaces; and a coupler comprising a coupling portion coupling the first and second light guiding lenses over the light shielding plate, the coupling portion having a cross section smaller than other portions of the coupler.
