illuminated keyboard

Abstract

The invention relates to a light emitting keyboard. The light emitting keyboard comprises a base board, a light source circuit layer, a switch circuit layer with a plurality of switch units, and a plurality of key caps which correspond with the plurality of switch units. Each key cap has a transparent area and a key cap projection space. A key cap gap, a plurality of light emitting assemblies in each key cap projection space and a plurality of light guiding plates are arranged between two adjacent key caps, wherein the plurality of light guiding plates are arranged in the key cap projection spaces in a manner of being separated from each other. A light guiding plate gap is arranged between two adjacent light guiding plates. The light guiding plate clearance at least extends below the key cap gap. The plurality of light emitting assemblies correspond with the plurality of light guiding plates, thereby supplying light to corresponding light inlet surfaces of the light guiding plates. Furthermore each light guiding plate guides the light to be emitted out of each upper light outlet surface, thereby emitting the light out of the transparent area of the corresponding key cap. Therefore, the light guiding plates which are separated from each other form an independent light guiding mechanism, thereby limiting the light so that the light can only be transmitted in the corresponding key cap projection space and preventing optical interference between adjacent buttons.

Description

technical field [0001] The present invention relates to a light-emitting keyboard, in particular to a light-emitting keyboard which can avoid the interaction of light energy between light-emitting keys. Background technique [0002] Keyboards are very important input devices for electronic products (especially computers), and the development of keyboards is closely related to the convenience of users. In order to operate the keyboard smoothly in the dim environment, the illuminated keyboard has gradually become the first choice of consumers. In the existing light-emitting keyboards, light from a single or several light sources is usually guided to all keys of the keyboard through a whole light guide plate corresponding to the size of the keyboard, thereby making each key light. However, the light between the keys of the light-emitting keyboard is easy to interfere with each other, and the independent control of the light emission of each key is lacking. [0003] Therefore,...
