Keyboard lamp and control method thereof and keyboard with keyboard lamp

Abstract

Disclosed is a keyboard with a keyboard lamp. The keyboard lamp comprises a light emitting unit and a controller, wherein the light emitting unit is arranged on the keyboard and the controller is used for controlling the light emitting unit to light or extinguish after the keyboard is powered on and comprises a key input detecting unit, a timing unit, a comparing unit and a control unit. The timing unit is used for calculating halt time after key input on the keyboard is stopped when the key input detecting unit stops receiving the key input signals. The comparing unit generates a comparing signal when the halt time is longer than the preset time. When the lighting unit emits light, the control unit generates a first control signal after receiving the comparing signal and controlling extinguishment of the light emitting unit according to the first control signal. The invention further provides a control method of the keyboard lamp. The keyboard and the keyboard lamp thereof are simple in structure, and the light emitting unit can be lit and extinguished according to actual using conditions of the keyboard of the user, so that power is saved.

Description

technical field [0001] The invention relates to a keyboard light, in particular to a keyboard light with power saving function, a control method of the keyboard light and a keyboard with the keyboard light. Background technique [0002] The keyboard is one of the input devices of the computer, but the keyboard itself does not have a lighting lamp.
