Luminous keyboard

Abstract

The invention relates to a luminous keyboard which comprises a key module, a keyboard base plate, a light guide plate, a light source and a first reflecting piece, wherein the key module is provided with a keycap, a scissor bracket, an elastic component and a film circuit board; the keyboard base plate is provided with a key connecting part which corresponds to the keycap and is integrated on thekeyboard base plate and used for fixing the key module on the keyboard base plate; the light guide plate is arranged under the key module and on the keyboard base plate and is provided with an incident surface, a bottom surface which is crossed with the incident surface, an emergent surface which is opposite to the incident surface, and light holes which correspond to the key connecting part; thelight source is arranged at one side of the incident surface of the light guide plate and is used for projecting light into the light guide plate by the incident surface and ejecting the light out ofthe light guide plate by the emergent surface; the first reflecting piece is arranged under the bottom surface of the light guide plate, is used for reflecting the light output from the light source into the light guide plate, and is provided with through holes which correspond to the key connecting part; and the through holes also correspond to the light holes.

Description

technical field [0001] The present invention relates to a luminous keyboard, in particular to a luminous keyboard with an innovative light guide plate. Background technique [0002] Illuminated keyboards have gradually become a new trend in computer equipment in recent years. More and more computer keyboards will introduce light guide plate and light source technology, so that users can still use the keyboard easily in many occasions where the light source is not ideal. The existing light-emitting keyboard structure generally includes, for example, a keyboard portion, a backlight device, a bottom plate and a light guide plate. Some existing layer design structures are complicated. The light guide plate in the light-emitting keyboard using the light guide plate has a multi-layer design, and this kind of light guide plate is mostly arranged at the bottom of the keyboard, far away from the desired lighting part of the key, and the light source passes through the light guide pla...

Problems solved by technology

The backlight device 25 is an EL. Although the overall thickness is relatively thin, the EL requires a large voltage when activated, has a short life, and will become darker and darker. The circuit is complicated, and there is also the problem of electromagnetic interference with the keyboard film circuit board.
