The application relates to the technical field of keyboards and discloses an independent light-emitting keycap module and a keyboard device. The keycap module comprises a main body part and a base part, the main body part is a key unit capable of being independently disassembled, is provided with a downwardly-opened groove, a side light-emitting type light-emitting
diode is arranged on the side wall of the groove, and an electric connection terminal is located in the center of the groove and is electrically connected with the light-emitting
diode through a conductive circuit. At least two opposite acrylic reflective bumps are arranged in the groove to enhance
light reflection. The base part is provided with an electric interface matched with the electric connection terminal, mechanical and electric pluggable connection is realized. The keyboard device comprises a plurality of independent light-emitting keycap modules, is installed on a
key frame of a keyboard body, and is electrically connected through a
printed circuit board. Therefore, each keycap of the application can independently emit light, is of a detachable structure, and is convenient for replacement and maintenance.
