The keycap of the traditional structure is light-transmitting itself, while the keycap prints light-transmitting characters on the surface and adds an opaque coating on the surface other than the characters, so that the light on the backlight panel is transmitted to the keycap to achieve the light emission of the characters on the keycap. The lamp cavity 101 of the present solution is equivalent to setting a recess at the thickness of the keycap. When the light source is placed in the lamp cavity 101, the light 101 enters the interior of the keycap from the thickness direction, and when encountering the optical microstructure, the light is emitted from the optical microstructure to achieve a focusing effect.

[0025] In addition, in order to achieve the effect of focusing light at multiple locations in the keycap, the plurality of optical microstructures 2 form a plurality of optical microstructure sets distributed at intervals, which is equivalent to the light emitted from the light source in the lamp cavity 101 being transmitted along the inner layer of the keycap and being gathered on the plurality of optical microstructure sets to form a plurality of concentrated light spots, thereby facilitating the realization of a variety of light effects on the surface of the keycap.
[0026] Specifically, in this embodiment, the optical microstructure set includes a first optical microstructure set 21 distributed along the periphery of the lamp cavity 101, a second optical microstructure set 22 located outside the first optical microstructure set 21 and distributed along the periphery of the back side 110, a third optical microstructure set 23, a fourth optical microstructure set 24, a fifth optical microstructure set 25, a sixth optical microstructure set 26, and a seventh optical microstructure set 27.
[0027] Moreover, in this solution, in order to facilitate manufacturing, the optical microstructure 2 and the lamp cavity 101 are integrally formed with the key cap 1 .
[0028] In addition, in the embodiment of the utility model, the lamp cavity 101 is close to the center of the key cap 1 .
[0029] The utility model also provides a keyboard, comprising a keyboard body, on which the luminous keyboard keycap is arranged. As the luminous keyboard keycap is included, the keyboard also has corresponding beneficial effects.
