Abstract

The invention discloses a light-guide fiber colorful light-emitting keyboard and a main board control circuit thereof. The keyboard includes a color-varying light-guide fiber ring, RGB light-emitting diodes providing light sources, a circuit main board, a keycap plate and a bottom plate; the RGB light-emitting diodes are fixed on the circuit main board; two lead-out ends of the color-varying light-guide fiber ring are respectively connected with the circuit main board; the circuit main board is fixed in the bottom plate; the keycap plate is bonded on the bottom plate; a wire clamping ring groove for accommodating the light-guide fiber ring is formed at the edge of the bottom plate; a protruding cover matched with the wire clamping ring groove is formed at the edge of the keycap plate; and the wire clamping ring groove and the protruding cover are both made of a transparent material. According to the light-guide fiber colorful light-emitting keyboard, the light-guide fibers are clamped in the wire clamping ring groove; light-emitting effects of two of the RGB light-emitting diodes are led out to the periphery of the whole keyboard by means of the light-guide features of the light-guide fibers; the RGB light-emitting diodes and the light-guide fibers are used in cooperation, so that colorful light emission can be realized at the periphery of the whole keyboard.

Description

technical field [0001] The invention relates to the technical field of luminous keyboards, in particular to an optical fiber colorful luminous keyboard and a main board control circuit thereof. Background technique [0002] The keyboard is currently the most common input device and is used in various electronic products, such as mobile phones, remote controls, personal digital assistants, personal computers, and so on.
