The invention provides an operation state indication circuit for electronic equipment. The operation state indication circuit comprises a control unit, at least one buffer and a plurality of light-emitting diodes, wherein the control unit is used for correspondingly outputting a plurality of groups of different electric signals according to the operation state of the electronic equipment, the buffer comprises at least one input terminal and at least one output terminal, the at least one input terminal is simultaneously electrically connected with the control unit for respectively receiving a group of electric signals output by the control unit, each output terminal corresponds to each input terminal for correspondingly outputting a group of level signals which are the same with the electric signals received by the corresponding input terminal, and each light-emitting diode is electrically connected with each output terminal and used for indicating the operation state of the electronic equipment under the control of the level signals output by the output terminal. The operation state indication circuit for the electronic equipment can facilitate the monitoring of the operation state of the electronic equipment by a user.
Description
technical field [0001] The invention relates to an indicating circuit of electronic equipment, in particular to an indicating circuit used for indicating the operation status of components inside the case of the electronic equipment. Background technique [0002] The motherboards and hard disks of electronic equipment such as desktop computers (Desktop) and servers (Server) are all placed in the case, and it is usually difficult for users to know the operation status of the motherboard and hard disk in real time while using the electronic equipment. When it is found that the electronic equipment is operating abnormally, the user often needs to disassemble the case for inspection, which brings a lot of inconvenience to the user. If a separate indicating device can be set outside the casing of the electronic equipment to instantly display the operating conditions of the main board and the hard disk, it will be beneficial for users to monitor the electronic equipment at any tim...
