Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments in the present description, belong to the protection scope of the present invention.

Example one

As shown in fig. 1, this embodiment provides a luminous key, including key body 1 and control circuit, key body 1 includes a plurality of keys, and each key below is equipped with corresponding backlight unit, backlight unit includes backlight 2 and luminous body 3, luminous body 3 sets up one side of backlight 2, preferably, luminous body 3 sets up one side that the user was kept away from in backlight 2, just luminous body 3 with the control circuit electricity is connected. Then when the user pressed the key, can make control circuit switches on to control luminous body 3 gives out light, and the light source spreads to whole key surface through the diffusion of 2 boards in a poor light this moment, carries out even luminescence, thereby the user is when playing the key, and light covers on whole key surface, thereby avoids the user hand to hide and influences user experience as light or the luminous inhomogeneous.

Wherein it should explain, it is concrete, equally divide in the below of each key body 1 and do not be provided with a board 2 in a poor light, and all be provided with corresponding luminous body 3 in one side of each board 2 in a poor light, and each luminous body all is connected with control circuit electricity, and when the user pressed the key, trigger control circuit switched on with the luminous body that corresponds to make luminous body 3 send the light source, and spread to the surface of being pressed the key through the diffusion of board 2 in a poor light and carry out uniform light-emitting.
