Luminescence keyboard device

Abstract

The invention provides a luminous keyboard device, which includes a plurality of keys, a plurality of luminous elements and a membrane switch circuit. Each button includes a key cap and an elastic element, the elastic element is arranged under the key cap, and each key cap has at least one light-emitting area, and each elastic element has a protrusion, and the protrusion is located inside the elastic element. A plurality of light-emitting elements are arranged under the plurality of elastic elements to generate a plurality of light beams projected to the plurality of light-emitting regions. The membrane switch circuit is arranged under the plurality of keys, and the plurality of elastic elements are arranged on the membrane switch circuit, and its protrusion is located above the plurality of contacts of the membrane switch circuit. When any one of the keycaps is pressed, the protrusion The part is pressed downward against the membrane switch circuit, so that the corresponding contacts of the membrane switch circuit are in contact to generate a corresponding key signal. The invention can effectively improve light use efficiency and luminous uniformity.

Description

technical field [0001] The present invention relates to a keyboard device, in particular to a keyboard device with a light-emitting function. Background technique [0002] The keyboard is a commonly used computer peripheral device for inputting text or commands to the computer. Recently, keyboard manufacturers are devoting themselves to developing various keyboards with special functions to meet the various needs of different users. For example, in order to enable users to clearly see the words on the keys in an environment with insufficient light, there is a luminous keyboard. . [0003] The following describes the structure of the existing luminous keyboard, please refer to figure 1 , figure 1 It is a schematic cross-sectional view of an existing luminous keyboard. [0004] Firstly, the elements of the existing luminous keyboard will be described. As shown in the figure, the conventional luminous keyboard 1 includes keys 11 , a membrane switch circuit 12 , a support p...

AI Technical Summary

Problems solved by technology

[0011] Based on the above description, it can be seen that the light use efficiency and uniformity of light emission of the existing luminous keyboard 1 are not ideal, so an improved luminous keyboard is needed to improve the problems of the existing luminous keyboard 1
