Abstract
A keyboard with a light guiding nameplate includes a keyboard body, a light source, and a light guiding nameplate. The keyboard body includes an outer housing, a plurality of keys, and a circuit board. The plurality of keys is exposed outside of the outer housing, and the circuit board is accommodated inside of the outer housing. The light source is disposed on the circuit board. The light guiding nameplate has a light incident surface, a reflective surface, and a light emergent surface. The light incident surface is located inside of the outer housing and adjacent to the light source, and the light emergent surface is located outside of the outer housing. The light source is configured to emit light to enter into the light guiding nameplate from the light incident surface, the light is totally reflected by the reflective surface, and then emerges from the light emergent surface.
