Problems solved by technology

[0002] The keyboard is the computer peripheral most frequently used by users, but when the light is insufficient, the letters on the keyboard are often invisible to those who use the keyboard, which makes it very inconvenient for people who cannot touch type.
Although there are some luminous keyboards, most of these luminous keyboards can only emit light when the computer is turned on.

Abstract

A keyboard comprises a keyboard body, a keyboard control circuit, a plurality of keystrokes, an interface, a switch, and an LED, wherein the keyboard control circuit is arranged in the keyboard body and the plurality of keystrokes and the first groups of pins of the interface are electrically connected, the second group of pins of the interface are connected to the anode of the LED through the switch, the cathode of the LED is grounded, and the second group of pins are also used for receiving a positive 5V standby voltage and a positive 3V standby voltage on a main board. The keyboard can still shine when the computer is in a shutdown state.

Description

technical field [0001] The invention relates to a keyboard. Background technique [0002] The keyboard is the computer peripheral most frequently used by users, but when the light is insufficient, the letters on the keyboard are often invisible to people who use the keyboard, which makes it very inconvenient for people who cannot touch type. Although there are some luminous keyboards now, most of these luminous keyboards can only emit light when the computer is turned on. Contents of the invention [0003] In view of the above, it is necessary to provide a keyboard that emits light without turning on the computer. [0004] A keyboard includes a keyboard body, a keyboard control circuit, several keys, an interface, a switch, and a light emitting diode. connection, the switch is set on the shell of the main body, the second group of pins of the interface is connected to the anode of the light-emitting diode through the switch, the cathode of the light-emitting diode is gro...
