Problems solved by technology

[0007] However, since the light-emitting module 23 is arranged on the other side of the membrane switch circuit 21, the existing light-emitting keyboard 2 is close to the space bar (please refer to figure 1 ) transmits a relatively large amount of light, while in the existing luminous keyboard 2 the light transmitted from the side away from the space bar is relatively small, thus resulting in uneven luminous effects of the luminous keyboard 2

Abstract

The invention relates to a luminous keyboard. The luminous keyboard comprises a plurality of keys, a membrane switch circuit, a light emitting module used for generating light beams, and a light shield layer, wherein the membrane switch circuit is triggered by the keys to generate signals; the light shield layer used for shielding the light beams is arranged on the membrane switch circuit; and the amount of the light shielded by the light shield layer close to the light emitting module is large, so that the luminous keyboard can emit light uniformly.

Description

technical field [0001] The invention relates to a keyboard, in particular to a luminous keyboard with a luminous function. Background technique [0002] The keyboard is a commonly used computer peripheral device for inputting text or commands to the computer. see figure 1 , which is a schematic diagram of an appearance structure of an existing keyboard. There are a plurality of keys 10 on the surface of the existing keyboard 1, and these keys 10 are classified into general keys 101, number keys 102, and function keys 103, etc. These keys are pressed by the user's fingers to generate corresponding signals to the user. The computer enables the computer to execute the pressed key functions, for example, the general key 101 is used to input symbols such as English letters, the number key 102 is used to input numbers, and the function key 103 is used to provide various functions, such as F1-F12 and so on. The normal key 101 includes a space bar 1011 located on one side of the ...
